Finally on the DYNO + FMIC! Audi A6 BiTDI Project! 

Ryan reliably coming through with the Sunday funday content like a boss 👌🏽

I just dropped my transporter to Darkside yesterday can’t wait to see what it’s like after they’ve done a few upgrades

Amazing content as usual👍I like how you guys explain everything in details and not only talking about numbers but also reliability of the car.Thumbs up Darkside😁👍

I'm loving the beep, every time I hear it I think oh the bloody dishwasher needs emptying. Then I realise it's on your vid, ANOTHER OF YOUR LOVELY VIDS cheers to you all.

Love these vids don’t understand it but still brill.

Love your work guys!!

Literally waiting for a A6 to get inspected by rac. Interestwd to find out what you guys can make happen

Great vid and info. Cheers

Hello great work once again 👍

Reyt then, love it!

Reyt then!!

Exciting times ,turbo next 😊👍

Loved the episode Ryan, I really enjoy seeing the small changes making differences or sometimes making things even worse. 25:1 afr and you're making 370 hp, even when going to lowest safe afr (16:1 and without dpf maybe) you still would only gain 20ish HP?

Production quality, now on the. Same level as, tuning science. #darksidesunday 👍🏻

I've done the air box mod using a sofet board round vent (No I'm not joking) ... I'm interested to see the next installment and see the MAF readings...🤔

Looking forward to seeing how the air box mod works would love to buy a similar piece for my A4 airbox. Please show the difference with dpf on & off in a video also.

Can't wait the ability to order parts for my A6 TDI from you.

Are you guys planning on removing the swirl flaps? Can't wait for the hybrid turbo vid...

Would like to see a vid on A4 2.0 tdi b8.5 sometime if possible but great content as always 👍🏻

I enjoyed this episode. I can’t wait for the rest of this series. It would be interesting to see what difference the DPF delete makes on power on this tune before the hybrid turbo upgrade. The results of this project will decide what I quote for you to do to mine!

fun to watch! just got myself a bitdi also, so its extra fun to see the mods and power you can get :) what do you also think of the oilchange in the tiptronic? since audi and other shops says no.. its "lifetime"..

Miss mine, hope your having fun with it, if you've even touched it (Audi A6 Avant) really wanted mine to go through this after you did the testing but unfortunately it wasn't to be Still enjoy these vids either way and I will continue watching

My Labrador hates your videos thanks to that beep 😂

That beep man🤣🤣

Very informative content as always. Wondering how often you get pulled over for the private plate though.

Great video guys, does a tune from you solve the Audi EGR emission fix issues?

13:27 "Sackable offense" :D

what would be interesting would be the difference between an original dpf and then a down pipe with race dpf, on this car.

That’s what darth vader tows his star destroyer to his mechanics with 💪🏻💪🏻💨💨

Ryan I have no Idea what you are talking about but it's brilliant lol

Picking up a cheap 15 3.0 a6 allroad this coming week hmmmmmmm ideas ideas ideas 🤑

What happened to the airbox mod ? Any update ?

Watching this project closely. I have the slightly newer 320bhp engine rather than the 313bhp can I expect similar levels of power increase? Would you advise against remap without new intercooler? Is that a false economy? What impact does the intercooler have on turbo lag?

hello, maybe you can write the dimensions of the air ducts with the hole where you make the 3d printer

Very informative video. Whats the max egt the car can handle without damaging anything? Ofc without the dpf

We only get the single turbo here in the US. Does anyone know if the block is the same? Or at least if ours is as strong? I want to modify but I've never messed with these tdi before. Doesn't seem like there is much support over here (I get that we don't have as many diesels here.)

The normal 3.0 TDI engine after 2012 is it problematic? What do you guys have for experience with those engnies. Are they good and relaible?

Got the same car, with a tune. Should i be worried about My dpf? I would like to have it for some years, ha.. Should i also Chang the oil Thing? Mine got 374 and 770nm. I am from Denmark, and had the tune from the best here..

I have a 2. 0tdi c7, 190hp, would this fmic fit? Do you make one specifically for it?

I MAY (ahem) have had a remap on mine, only got it to 360, my daily driver so didn't want to push it too hard but I didn't get an intercooler, it's just stock. Is there any cause for concern you think? Many thanks and great vid :)

Does the intercooler fits plug and play with the single turbo? The bitdi needs different silicone hoses, but the single turbo doesnt need, or?

Hi DD. How come you dont use the Wagner Competition intercooler, that you offer to this car from your webshop?

Very interesting article. I have bought a 3.0 BiTDI and it kangaroos slightly at around 20mph...stuttering. Audi UK is aware and apparently it's gone all the way back to Germany for review. They are hoping to publish a technical note on what it is. Audi UK says it not the turbos, rails or injectors. V odd.

What is the difference between Darkside intercooler and the Wagner intercooler? Because I'm looking to buy one and the difference in price is huge.

Is it correct that you shouldnt tune the 272ps engine with the 7 speed S Tronic 'box because it cant cope with the increased torque? Hence why Audi fitted the 8 speed ZF to the BiTDI engines.

Whats your future plans regarding the emissions test get stricter,will you always be diesel tuners

Hello, I have an Audi A6 (allroad 4g c7) 3.0 diesel biturbo 313 hp, I broke the turbo and I want to replace it and I want to install a good turbine to work well and powerfully. Can you recommend something?

I've a question about this engine, can it be fit to a b8 a4 quattro 3.0 tdi ?

is there a way to remove egt ? :D or thers alternative to it so it wont melt down ? if u get more horsepower than 400+ ?

How reliable are these engines? Heard issues with them- true or not?

Dude do you do these vids straight after lunch down the pub?

Hi guys, I've got a 2010 A4 B8 with the CAGA engine. Having a problem with coolant temp not reaching 90' degrees, even after an hour drive - only reaches 75'/80' degrees (although fairly quickly). Temp also drops going down hills. Could this be the secondary inline thermostat behind the engine?

What is the difference between the C7 and C7.5 bitdi engine, looking at stage 1 tunes offered by companies the C7.5 is alot more capable factory is this true?

Ryan can you recommend an a5 3.0tdi wheel bearing puller?

so what did u actualy do with rail presure sensor ? how do u guys upgrade it ?

Does anyone know what the park code is for the fuel rail pressure sensor?

Could you maybe add water/meth injection before adding the hybrid turbo?

R E Y T T H E N

What do you all think? BMW 335D or A6 3.0 BiTDI what would you prefer?

You went from 77°C to 29°C on the Intercooler? Asking for a friend who purchased a intercooler.

Small edit seen the direction of replies, I do not like to start a flamewar about numbers, far too old for that shit. Below post was intended to help others with my (expensive) lessons learnt, what happens in case you push the biturbo tdi over the max. I do not care if the power claims of "my tuner" are toom high, the engine didn't last and I moved on. Love the DSD content a lot, keep up the good work guys. I have quit some bad experience with a tuned Biturbo TDI A6. It was done by a apperantly very respectable tuner, mounting the wagner FMIC, and replacing the airbox by a RS6 airbox (which is less restrictive). It got a custom tune delivering very solid numbers, 460hp/925Nm, speed limit was removed, so managed to put close to 300kmh on the odo several times commuting Amsterdam - Hamburg every week. The fun didn't last too long.On the Autobahn (unlimited speed) the engine seems to get overheated at Autobahn moderated speeds (200-220kmh), without showing any alarm, it just starts dumping coolant till it reaches minimum levels, and then the alarm comes. The coolant spill will initiate below the tank. If you increase the common rail pressure, another point of attention are the 6mm tension bolts that are holding down the injectors, they will fail in the end causing injectors to start leaking and in the end loosing them completely by being blown from their seats (again without alarm). On top of that, with the cone filter upgrade in the RS6 airbox, the car was eating MAF sensors, and with a MAF limb mode the car was unable to being driven. In the end I always carried a MAF sensor with me, which is luckily only a 125 euro piece that is nowhere to be found on stock.....and it always happened on Sunday nights too.... For me this was the moment I decided to leave Audi for what it is (having the 4th injector tensioner, and continuous overheating / coolant dumps inside the left wheel causing braking problems in the end, switched to ///M and never looked back. Keep up the good work and you very informative channel, but be aware of the problems when pushing these engines, mounting these massive FMICS in front of a radiator is in general not a good idea. I do believe the problems only surface at extended periods of 200+kmh therefore the upgrades it could work when driving and occasionally sprinting in any country other then Germany, however the 6mm tension bolts seem to remain the bottleneck even when in standard tune, so it would be great to develop a quick fix, which should be easy, but reassuring for your customers. Cheers Erik

What did the 4.2 touareg you mentioned, make on the dyno!?!

Why do you never show the dyno runs?

Have you ever flowed the TDI cylinder heads or before and after dynoed a car after having the cylinder heads have been properly ported?

what pressure makes the small turbo?

Think the cooler is to big . Maybe 25% bigger would give better power but higher intake temp .

what do you think of the 3l I6 diesel engines from BMW? the B57, is it better than these TDI units, and are they tunable?

Any reason why you went with Bentley wheels?

Now remove the DPF and straight pipe it. : )

Shame they don't do Mercedes

Where do you get the silicon air intake tip from?

Ffs Tom 😂😂😂😂

All The btdi is the same? 313,320,326 (competition)? Same engine? I have a competition, stage 1 tuned, claimed to be 406 hp, 750 newton, thats bullshite then?

Where’s the follow up video? Keep checking but sad reacts only.

hello, i have one question: in croatia, police interceptors are stock a4 3.0 tdi, quatro ,single turbo and i doubt they tuned it illegally, because it can reach 263km/h. so they remove speed limiter(250), and should do some things more, question is what they changed , but it must be done by few clicks on laptop and without dyno test, because they have dozens of that cars and it woult take too long and too expensive

You should make him present the next video as punishment for interrupting you...

you could damage the dp... what? 😅😂

if i win lottery ..im there man :) engine master! .respect. i own a6 2 td

What happened to this guy?

I can't understand what he is talking...

Water meth??
