I respect the fact that you are willing to say, "I don't know." Thanks for putting out genuine content that helps point us in the right direction rather than just trying to sell us expensive parts!

17:05 Me watching the clutch pack fall apart and tossed to the side: “I hope you remember the order it goes back together ”

You have no idea how your tutorials have helped me out in the last year. They've helped me approach difficult repairs with way more confidence. Thanks guys.

I did this in my driveway with jackstands in the middle of winter. Took 2 weeks. You guys make it look easy!

I love the raw honesty that you portray, but the best comment had to be “it was better than replacing a heater core”! Cheers Drew

"it was better than a heater core" says so much... rad video, thanks as always for the very genuine content!!

I just fixed my sons S4. 2nd gear shift solenoid intermittent failure. When re-installing the valve body, the humble mechanic on his page said 28mm. In this video, he said it may depend on your year. Well my sons B8.5 I noticed it was about 4mm off. I set the servos for 32mm and it fell right into place. Great video.

Just from my experiences, after seeing the clutches were burnt and that was more than likely the "main" problem. I would have done a timing kit since the trans was out. 19:08 was some scary stuff man. Imagine the motor being just fine but the hydraulic tensioner decided to fail on start-up from sitting for a period of time. I enjoy watching your shows. Keep it up.

Thank you for these fantastic videos. They are of enormous value. Well done.

I am planning on buying a DSG VW this year and I am glad I bumped into this channel.

I did the circuit board replacement on my B8 S4 on my driveway. Here is a tip. If you ended up like me trying to push the mechatronics and it doesn't go in place, even with everything aligned by the book. Get six M6 long bolts(100mm long). Use them in place of the short bolts, they'll keep all aligned properly, push it in place(was a snap), then replace with the correct bolts. My S4 is working like a champ, don't know for how long. 😊

18:27 I was afraid my wife would walk in the room during this part

The fact you can deal with these transmissions speaks to the skills you have learned over the years.

For anyone who needs this… I have a b8 s4 and from complete stop to driving it would jolt really hard. 500$ harness and valves on the mech unit and it runs smooth now!

Charles nailed it "Better than a heater core!"

The stalling looked like the clutch calibration was way out of whack, most likely because operated for so long when faulty. The controller just tried to slowly creep, but because the old shot clutch needed rather high pressure to do that, the controller just send that high oil pressure there. The new clutch grabbed way stronger on it, so before the controller had any chance to respond, the engine stalled. Same reason for the jerky shifting afterwards. I would guess normal procedure would be to reset the calibration. But as it managed to run, it will gradually recalibrate itself even on its own, it will just take some driving time, preferably involving a lot of shifting at various engine loads. For the exhaust bolt direction: I'm pretty sure the engineers knew what they were doing. The thing is, they have to observe other objectives too. First of them is to make sure it will be possible to disassemble even when exposed to road salt. The thing is, the flange forms a kind of barrier, preventing the salty mist just above the road to go above that flange. So what is below, will be way more exposed to that salty mess vs what is above that flange. This way below, so more exposed is just the bolt head, which is rather immune. The way more sensitive thread is then on the upper, cleaner side. Putting the nut down means the thread would be the more exposed part, so more likely get completely jammed by corrosion. And the other aspect is related to the car makers priorities: They care for these things to be serviceable at least somehow, last till the end of the warranty period and then be cheap, so fast and simple to assemble on the production line. The fact it becomes harder, so more expensive (labor) to service after the warranty goes out is not their problem, that would be paid by the customer. Plus I don't think disassembling this would be that big of a deal either, taking into account you have to replace that bolt anyway. So taking an impact hammer-wrench to loose it from the bolt head side and so eventually snapping off that bolt heat would still be good enough way to disassemble that.

In 2007 I bought a 2005 TT with DSG. The DSG was a new thing then, it was only the second year of production. and everyone worried about how costly it would be to repair. About a year in, my TT started shifting really badly…and I thought to myself “oh hell, this is gonna hurt”. I took it into a dealer and they called me the next day to say it was fixed. Turns out the DSG was fine. They replaced a Brake light switch for $45 bucks and it ran perfectly. Apparently, a signal from the brake light harness is important info the car uses to decide which gear to preselect? Anyhow… I still have that car at 130k. The 6 speed DSG still runs perfect.

Where have you guys been? Miss the more frequent videos and definitely miss the cars with cocktails podcast.

I have a 2013 S4 that has a donor transmission from a 2016 S4. I was one of the first S4 owners to post online about upgrading the transmission. Got it done at JH Motorsport . Turns out the B8.5 Transmission does fit in the B8 , but it needs to ODIS to code the unit to the car. Great content fellas.

Just bought a 17 S7 with 55k on the clock and mech unit was JUST done by Audi before I purchased so hopefully I dont have to try and tackle this anytime soon... great informative video!!!

Love your video. Now I know why I recently purchased a manual (5 speed) VW car (not sold in the USA) rather than spend the USD 2,000 for the more powerful engine but 7 speed DSG. I couldn’t face having transmission issues in the future. Keep up the good work.

Hey! That's why I rather have a manual transmission, RELIABILITY!!!!! and proven repair method 😁. Nice job guys, I love to watch both of your channels 👍

Amazing content, I replace mechatronics units on these gearboxes regularly, and I love the job, as I work at VW as a master tech in the U.K. ! We also replace the internal filters, the job at Audi here is about £4k £3299 for the mech So it’s amazing to see you repair one as we just replace and code with ODIS. Great video 👌👌

Very interesting video, personally I have never really worked on DSG gearboxes. I once worked on a Mercedes w221 gearbox that had it's clutches all burnt due to oil starvation, the transmission oil ran close to the radiator with coolant. Defective seals were the culprit.

Have before. Bought a Mk5 Jetta TDI from a customer that needed a K1 solenoid. Pulled the mech, cleaned it, changed the fluid/filter and swapped the K1. Still running and driving years later.

My mechanic just recently bought a s4 with a bad Trans, and he replaced it for about $2500, considering that the mech unit alone cost basically as much you 100% should just replace the Trans and don't bother with dsg nightmares.

Oh man im happy that i only have manuals 😂 It was still interesting to watch and a lot to learn.

GREAT! GREAT! GREAT! video on the DSG trans!! 17.7015 in-lb = 2Nm

Big reason why I Sold my MK7 GTI (DSG). It was having horrible whiny noises when in 5th-6th gear. It drove me insane. local Volkswagen shop told me it was definitely the transmission, and that I was better off just replacing the whole thing. It was still gonna cost me an arm and a leg even if I were able to find a used one. Parts + labor was still too much. Considering this was going on during the pandemic, when money was tight. I miss the car like crazy, but oh well. Definitely not worth the headaches.

Its so cool to see the trans pulled apart and fixed nowadays, as an audi tech the modern “repair method” is just replacement rather than fixing it

Just did this today on the Q5 and the measurements got our heads spinning trying to put it back with a 28mm. We ended up reading some comments here and 30.2 mm got us going. Thanks everyone 🎉

My obdeleven was in fact, purchased from shop DAP

Great work, knowledgeable and funny!

I replaced the clutches in my 13 S4 in my garage. I ended up just putting the car into service position and pulled the entire engine out. Having a lift would be nice, but it is possible to do it without it, just a "bit" more work lol Mine were a little toasty, nothing like those clutch packs were... Mine were slipping due to a piggy back without a TCU tune.. extra power without extra clutch pressure is a bad idea everyone!

I have replaced a dsg gearbox in a 2010 125TDI diesel Jetta with one from a 2007.103 TDI Jetta. It worked straight up with no coding however the gear change points were not right for the more powerful engine. So I then replaced the mechatronic unit with the one from the original gearbox and presto it all worked as it should and we still have car.

Awesome video! I know you guys are super busy I just wanted to throw it out there that I really miss Cars and Cocktails! Will they're ever be anymore episodes?

I already LOVE Manual Cars, after watching this, makes me love them even more 😂

If you guys ever create guides on how to fix a DSG, I would pay. Just as a heads up as an additional revenue line for the both of y'all. I'm an electrical engineer and I love seeing these beautiful units get tore down. I also laugh at your comments about the engineers not knowing any better, cause man, it's so true. I have to try to realign my ME's design so that it doesn't piss of a significant amount of people later lol.

I bought a 2012 S4 and the metatronix was installed incorrectly and all I had to do was installed it correctly and the thing ran like a champ. Make sure install correctly.

love it so much when you guys are together lol

Just to make things easier. The measurements depends on the pins that must be set to neutral inside the box. And for some knowing the production date. Thank you for the video 🇿🇦

Replaced a mech unit on a mk6 golf and just like yours it would stall in drive even after adaptation of clutches, but after some driving it got a lot better with mild problems when cold. In the end car got to the dealer and they replaced the clutches too. Old mech unit had a cracked housing on the accumulator.

Great video, very helpful did you run all the Adaptation below? 1, Erase Counter for Start Stop Process. 2, Clutch Valve Calibration 3, Distance Sensor Calibration 4, Reset Start Point Adaptation to Factory Settings. 5, Engagement Point Adaptation

Iv got a GOLF MK6 R in the UK and it’s only in 76K and runs like a dream,gear changes are so fast,but I’m going to be putting in a DQ500 in next year as there stronger than the DQ250 because I’ll be going for much more power,DSG is a great box i love it but I’m really lucky because my mate build these boxes and knows them inside & out does RS3 builds in a MK6 GOLF R or a R36 engine in a MK6,many things so I’m blessed if something were to go wrong

Very nice video . Please note that these tcu's can be cloned with tools like PCM FLASH , this will allow the DIY guys to not have to go to the dealer or use ODIS with geko account .

You guys together is just the best shit ever!

Yes b8.5 videos. Love it. I have a 14 s5

great video.

After replacing the clutch pack the clearances will be different to the adapted values. Therefore using a new or used clutch pack always requires basic settings and adaptions to be performed. Hence when you tried to select drive or reverse it stalled. But repeated attempts will probably get it to work as its always adapting.

Good engineering job guys, congratulations from Hungary. You might know a country where the A3, TT, S3 were produced and still.... Rgds Jácint

Love S4 content

Maybee you will tend with making such a great video with the Jatco Tiptronic wich were used in the MK4 Golf.

My dad and I replaced the clutch and mech unit on my 2013 s7 last month, fixed all my shifting/slipping problems! Did it in the driveway on jackstands as well, that was a nightmare lol

As long as you have the tools and repair manual, you're good to go!

Hi, so I'm at a stand still on my issue. I'm currently stage 2+ ecu stage 2 tcu with unitronic, and I have had quite the issue with the car jerking really bad on upshifts with moderate to heavy acceleration. Transmission shop said it was mounts so I replaced those with street densities but im still having those issues. What else could this be if it's not Transmission/mechatronic issue? I have obd11 but not sure how to read/watch logs and no codes ever show up. EDIT: I'm not sure if this is an issue with the tune or k04, it was doing this beforehand at stock and k03 as well

My experience is limited to a 2011 Jetta with 7 speed DSG. Two recalls, both for DSG made no difference to the shift and take up quality, which was very poor before and after. At 45,000 km we decided to sell. The best we could get for it was Au $12,500 - for a four year old, always VW serviced, in otherwise good condition. So the depreciation was Au$0.50 per km!! An expensive car

I did think you were gonna read that whole list. I was pleased when you didn't. : )

Sounds like an endless money pit, and time sapping excercise, given it seems like the bermuda triangle of transmission issues. Give me a cold beer at the beach anyday over doing that, sure was fun to watch though.

I worked on several 1st gen DSG’s or Don’t Shift Good transmissions... the Megatronics were a HORRENDOUS mess!

Watching this makes me happy that I got rid of the Audi I had I had an 05 A4 quattro it got to the point where every week something was wrong with it it lost power had sounds of air leaking from the boost piping and would not go faster than 50 mph

I refer to an article called [DSG SOP 5.0] Thru it I really understand how properly to use DSG

There are torque screwdrivers for this sort of thing. Check PB swiss tools for example.

The wheeler fat wrench is good for light torque specs, goes 10-65 inch pounds. 3 newton meters is about 26.5 inch pounds.

ive been an audi mechanic for 7 years now, incredible how bad those things are, the s-tronic in the b8 s4 is the worst, i am so happy to drive a stick shift with a single mass flywheel from factory that doesnt rattle and without a pos mecatronic, at least the b8+ are easy to work on, more money and less hassle for me :D

Nice video!!! do you think it is also possible to have the same result by only replacing the friction plate discs? or it is necessary, let's say a "long term repair" to completely change the clutch

I have a 2018 ttrs. Tried to put a wavetrac diff in. Must have gotten a clutch plate in backwards. Anyway reverse would not engage (only odd gears worked). New oem clutch and now I have R but still only odd gears. And r is slipping. Any idea? New oem clutch kit, New oem mech unit. Oem fluid used

I purchased a 2010 s4 which had a bad mechatronic 6 years ago. Purchased a new mechatronic online and had the dealership put it in. Cost me about $3500 with parts and labor. The interesting part was that the new mechatronic that I received stated that it was made it 2014. So I’m wondering if this would be the same mechatronic that is in the b8.5 s4? It was changed when the vehicle had 35k miles. I am currently at 123k miles on the vehicle and haven’t had any mechatronic problems since than.

Is there a final verdict on the GTI 6 speed DSG vs 7 speed DSG when it comes to tuning, power handling, and overall reliability?

What's the deal with the hesitation on the A3 when you take your foot off the brake? Feels like it's going to stall or its not in gear.

Ended up doing both tsb’s and a clutch upgrade on my b8 by myself. Tons of labor and parts and now i have all these special tools I’ll probably never use again.

I have a q5 2012 that was unable to engage in reverse gear. Mechanic indicated that I should replace transmission. With the replacement transmission I had to change the drive shaft. Took it to an independent programer to delete TCU files. Currently the replacement transmission drives smooth and engages all gears when cold, and when it is warm it slip in gear 3 and it produces the following intermittent codes: p17e100, p174d00, p17d800, p176b00. and it also produces static code: p179c00 This vehicle is a pain in the ass

Thanks for the video. My Passat flashes the PRNDS on the dash display when I put it into reverse :( and it hangs ... have to restart the car :((

Nice guys

My 2008 Volkswagen Rabbit. I'm glad it has a manual transmission built to last

Hello, I have a problem with the transmission when I enter the gearbox of 2 4 6, it gives me slight oscillations when walking at 20-30 km and in the march R it turns off when the car is cold

Can you fix my worn DSG clutch plates for me :), Its the dreadful 7 speed dry gearbox on the MK6 Golf

I'm having trouble with my auto Mk5 gti, tuned, apr catback exhaust, ecs air water separator, apr intake. NO CEL, but under heavy acceleration, when going into 3rd and 4th gear it almost hiccups or coughs but continues on as it should. 🤔 any suggestions? I'm getting alot of change coils and plugs but I don't feel like it's a misfire

Hi guys, my 170k S3 8P with DQ250 DSG made some clunk noise when shifting between D and R gears at a standstill, all gears function and no clutch slippery during full throttle, the gearbox had TVS stage 2+map, just the clunk noise make me wondering is there anything need to worry about? Thanks in advance!!

Hi .i got the leak from pin Connector on the inside on of my mechatronic unit.I have no errors ,but when changing from reverse to drive or other way round my clutch sometimes slips or just when driving in lower gears 1 and 2 ,Gears think changes at very low revs.In sport mode doesn’t change gears.I have no shavings in oil. Clutch and dms flywheel was changed like 30 000 miles ago.Adaptation was done.Any advice why is it leaking please?.I would much appreciate it.Thanks

Thanks Gentlemen very informative looking at an Audi TT mk1 3.2 with a gearbox fault fingers crossed I’ll be able to sort Can the mk1 be converted to manual transmission? Thanks folks 👍👨🏻‍🏭🇬🇧

My 2008 mk5 fsi 1.6l has a error code P0734 gear 4 incorrect ratio. What you show in this video would u say the fixes are the same

I changed my trans in my 16 S6, I had to swap my stock TCM over to the new trans. Everything went smoothly though. The old Mech was completely melted

I have a mk5 gti 2006 dsg suddenly every time it downshifts or hit the break a clunk sound appears like i hear the sound of the clutch engaging on every shift sound disappear on higher speed can someone help plz !!

I would like to know if the dsg of an Audi A1 or A3 would be easier/cheaper to repair? 2011 model

Halo, I have a Jetta 2006 DSG 6 gears. When I accelerate/decelerate past 1000 rpm the car jacks and drives smooth after that. The car jacks as well when in traffic if I shift from Drive to Neutral and vise versa.. what could be causing this?!

Please do more upgrade videos on the B8.5 s4! Something like the motor mounts! There are no videos on that!

Would it be cheaper to fix the DSG or do a manual swap?

Did you open the replacement clutch pack for inspection. Why didn't you simply replace the clutch friction and steel plates.

Hey guys, I've been watching your good videos for some time now and I saw this one more of my interest because I have a Golf mk7 2014 with DSG7 Diesel I bought this car used back in 2019 and I never replaced the oil of the gear also I'm in Portugal so I know some stuff is different from the US models, I was told that this oil of gear doesn't need to be replaced, is that true? I really want to keep my car running well specially in this department since it's very expensive to repair. BTW my car already have 212k km. I do confirm my motor housing is super clean no oils no nothing spilled. Thank you

2013 audi s4 b8.5, what type of oil do you use for the front diff? Or center diff?

I have an obd11 - what can I do to find the adaptations needed if I change the mech electrical harness?

Struggling with a no reverse and no even gears. Solved the slamming and jerking replacing the clutch pack but now ive got a clutch pressure too high code

Great video, I recently had a DSG issue where I could no-longer go into reverse or into even numbered gears ( 2,4,6) on my B8.5 S4 that had only 37k miles. Luckily I had an extended warranty as AUDI quoted the repairs to be £11k

Do you have any content on a 6sp automatic Quattro trans for a 2014?

hello please 2can you tell me how or what's the best way to know the oil level of this transmission

I recently brought an Audi A4 b6 avant 1.9tdi cvt. There’s continuous vibration when it’s in park, drive, neutral and reverse and the only time it would go away is if I put the car in neutral while am driving. The vibration gets louder at higher rpm. The other issue I notice, after while of driving hard and if I switch the car off and turn it back on it would crank up straight away I have to crank few times. If anyone had any issue like this please let me know how you managed to resolve this issue.

Have same issue with reverse was stall the engine. The problem was I was getting the pressure high for both clutches and I couldn't do the adaptation. So I checked the harness was good and I order the solenoids and now it running without problems

A common problem is mechatronic failure. You need to learn how to swap the mechatronic and flash it with it software. You can do it with aftermarket tools like kess cmd…

Is there an option for converting it to manual?
