DQ200 DSG Mechatronics full service! (Originally not building pressure) *PLEASE READ DESCRIPTION* 

☺️ That's great! 👍👍👍

☺️ Thanks! 👍👍👍

☺️🤪 It is easy to miss things... 👍👍👍

☺️ Thanks! 👍👍👍

☺️ Thanks! 👍👍👍

☺️ Thanks! 👍👍👍

☺️ Thanks Igor! 👍👍👍

👍👍👍

@@LMAutoRepairs could the oil filter be restricting flow or is the oil pressure sensor before the filter if switch is after filter with a few small leaks or pressure drop similar to your final test ie drop then build pressure then drop again ifthe filter not flowing enough it would not build enough pressure to cycle the motor on and off so my thoughs are filter thanks Luis

☺️ Thanks! Yes, was a nice day... 👍👍

☺️ Thank you for watching! 👍👍👍

Thank you for watching! 👍👍👍

☺️ Thanks! 👍👍👍

So do you mean those 20 M6 bolts inside?

☺️ Thanks! 👍👍👍

☺️ 👍👍👍

😅 Kinda of... yes... 👍👍👍👍

☺️ Thanks!

Can't remember how much it was... 👍👍👍

Thanks! 👍👍👍

Never seen one without the spring and the ball... Are you sure is not stuck in the old one, or you haven't drop it? 👍👍👍

Bizarre. I'm 100% sure there was nothing in the hole. Strange thing is I've also got a second new valve body which did come with the screw installed so I took that out to see and there was nothing in there either. Not sure what to do now!

That's incorrect... You can change the hydraulic fluid without removing the mechatronics... 👍👍👍

eBay... if I recall correctly... 👍👍👍

☺️ Thanks! 👍👍👍

Just google "dq200 pinout" and you will see the connections... 👍👍👍

@@LMAutoRepairs Thank you sir 🙏

☺️ 👍👍👍

If they replace the mechatronics and not other damage was inflicted to the gearbox, should be ok... 👍👍👍

I believe I covered that on the video... Or did I missed it? 🤔 👍👍👍

​@@LMAutoRepairs Mmmm. I think, this part is missed because I watch the video again but I didn't see the assembling of the pump. Do you know how much is thighten ? Please. 😰😓👃

@emmanuelnunezpereyra7347 OK... I might missed it... No, I don't know the torque specs... so I did it as I felt it was OK... Just make sure whatever you torque them all the same....

Yes... CAN high and CAN low... 👍👍👍

@@LMAutoRepairs and for Nm ?? Is possible send me your email or WhatsApp on pm ??

The title says to read the description... if you read it and follow the link in there, you will see if the car ended up working or not... ☺️ If the tcm is dead, that will most likely require a replacement.. 👍👍👍

@LMAutoRepairs read it after commenting thanks mate did itvit worked 😝

Enough...🤪 Unfortunately I don't have the specs for it... 👍👍👍

Just google the pinout of the mechatronics plug... then connect accordingly... that's just how I have done it... 👍👍👍

Oil pressure? You might need a good service on the mechatronics... 👍👍👍

@@LMAutoRepairs Thanks for the prompt reply. My transmission code is MFL, if I replace mechatronic with a used one from MFL…would it work or requires programming? Also, what do you mean by good service? Thanks

It might require coding... As for the service, have you watched this video?

@@LMAutoRepairs Yes, I did. This video gave me the idea to rebuild the mechatronic.

@@LMAutoRepairs Thanks a lot for replying back and sharing your knowledge. God bless you!

There is circlip, then just pull it out... ☺️

@@LMAutoRepairs yeah, i removed the circlip, i made an excessive amount of force, and even then, they wont budge, none of the 4, i will try a bearing puller today. i have made a lot of them but i never was able to remove any of the fork actuators.

👍👍👍

@@LMAutoRepairs compressed air through ports did the job!

☺️ Good technique... 👍👍👍

If the pressure accumulator is bad, your pressure on live data will drop really quick... As the accumulator is not really accumulating anything... Hope it makes sense... 👍👍👍

Hi one person should pour fluid on pump as u turn it should shoot out quiet firmly thanks

Hi It can be the mechatronics, however, if all the other gears and gear changes are OK, I would be more inclined for a mechanical issue in the gearbox itself... 👍👍👍

@@LMAutoRepairs could it be the synchronizer ring? Or low transmission fluid because once I took the car it started working in reverse but stopped again. Don't wanna sell my kidney to get it fixed

@@anki2451 It could well be... But until you take it apart it is difficult to tell... I just dubious that is the mechatronics, because if it was, you would most likely have issues on other gears... 👍

🤷‍♂️ Impossible to say what the problem is... Scan the car, check live data and go from there... Anything else, it is pure guess work... 👍👍👍

​@@LMAutoRepairs hi how much for a repair to a VW dgs 7 speed

That is the code for an internal leak or lack of pressure... could be many things, the accumulator, a seal somewhere, a cracked accumulator base... Needs opening checking and service... 👍👍👍

@@LMAutoRepairs all in the mechtronic unit? What about the TCU they saying that’s gone to and need a new one.

@Jason-hz5zc Why do they believe the tcu is gone? If the car is driving and just reports a fault I don't see it being faulty... Yes, the tcu is inside the mechatronics...

@@LMAutoRepairs he said the he refurbed the mechtronic and car doesn’t start so TCU needs a new one.

🤷‍♂️ Don't know what to say... Initially you said was driving and changing gears, now after refurbishment car doesn't start... Well, good luck...🤞

Previous dsg gearbox had issue made bang noise, lost power in gear, I had to get used gearbox

Which DSG is that, 6 liters seems a bit too much oil.... but, have you used the old mechatronics or is that the "new" one? 👍👍👍

@@LMAutoRepairs Old metronic

@kerbsideauto4940 OK... so, I would say, do an adaptation etc... if same problem, than you either have a bacd mechatronics or you got a bad gearbox...

Not long... as the pump will be constantly running trying to build up pressure... I am surprised that is running always OK, and not stopping with overheating codes... I would get that sorted ASAP... 👍👍👍

@@LMAutoRepairs no fault codes are showing mate live data shows it constantly running though and I can hear it buzz when I turn ignition on apart from that you want think anything was wrong with it it still drives fine

​@@shanehutchinson785 Again, the pump/motor is not designed to be constantly running, if it is now, will not last as long as it should, plus, I am sure soon or later it will start overheating, and the module will shut the pump off... I would have it sorted, or, you can drive it untill it goes bang... 🤷‍♂️

@@LMAutoRepairs thanks for your time mate

I was never able to undo one by hand... They are usually pretty tight! That could have been your issue...

I’m having problems to remove the acumulator: how do you release the pressure on it?

If you have the mechatronics removed, there is no pressure on that accumulator... Use a breaker bar... 👍👍👍👍

Can you not code it as present? 👍👍👍

No because in the uch using clip these options are greyed out and say absent using 210 of clip,is the security side on a separate chip,thinking only option is to see if either clone original data or exchange the chip etc

Ah... Try perhaps renolink...

I have renolink 152,can parts of the uch be reprogrammed separately,so as not to interference with security side of it.thanks paul. Have a great evening

Renolink goes a bit more in depth depending on the hardware and software of the modules, etc... Might worth to give it a go... 👍👍👍

☺️ 👍👍👍

Was replaced with what? A used unit? 👍👍👍

@LMAutoRepairs apparently a new 1 but it's still jumping in and out of gears after receiving it back within a month

👍

​@LMAutoRepairs Hi mate. I can see a licking from the pistons k1/k2 on my mechatronic. Is it possible to change the seals on the pistons without dismantle the whole thing? From the video it seems you can .

@@katalin9482 no you cannot you have to remove the mech in order to change both k1/k2 pistons.

You should be to do it, yes... Need to take the mechatronics out of the gearbox obviously... 👍👍👍

😊 👍👍👍

You just connect powers and can lines directly to VCDS... 👍👍👍

@@LMAutoRepairs I don't know which are the power and can lines im new at this

@LDR-cv5jr Just google DG200 pinout... 😉

Out where?

@@LMAutoRepairs on top next to the valve

Not sure what you are referring to... But either way, oil should not coming out from the mechatronics unit... You need to investigate further... 👍👍👍

I am on the other side of the pond... ☺️

Low battery can cause all sort of glitches and weird behaviours... 👍👍

@@LMAutoRepairs I left my lights on all night had to jump start my battery since the incident my spanner light comes on and D1 D2 D3 etc start flashing have live scanned it it's reading 32 bar and when I turn ignition you can hear the pump or motor on mechatronic I really believe it's down to my battery what damaged my mechatronic has it was fine before

​@@shanehutchinson785 Could be...

Got a quote for my mechatronic 850 British pound my pump/ motor stays on when you switch ignition on a bad battery would not cause that would it I'm i correct, what actually keeps the motor/pump constantly running please ?

​​@@shanehutchinson785 Possibly an internal hydraulic leak...

What are you struggling with? 👍👍👍

@@LMAutoRepairs I did the rebuild and it went fine but pressure couldn't build so the pump kept running. The only problem I could find when I first took it apart is that there was a significant amount of debris on two solenoids which I cleaned. The solenoids were tested and all worked and sounded the same when actuating. Then when I took it apart the second time I found that the O ring on the accumulator had split partly but looked fine otherwise. I believe that it could have happened due to not using any grease or oil when installing it to the new (and dry) valve body housing. Could this be the issue? I didn't use a torque wrench so maybe there was unequal distribution of tension on the screws? Although I felt I was tightening them all pretty much the same. My idea now is to take everything apart. Clean it with solvent and compressed air. Put it all back and torque everything the same. The new valve body came with the extra screw on the side and the pin on top but I'm now starting to question if there is a ball in there or not or if I was supposed to transfer the ball or balls from my original housing. Is it okay to take the pin out and the screw to check or is it very hard to put back together? Sorry for the long text but I tried to compress it as much as possible.

Easy to put back on... Yes, some housings come without it... You need to make sure that is in place. Also, check and double check the pump... if in doubt, get a new pump... 👍👍👍

@@LMAutoRepairs Okay let's see the latest development... I got a new O-ring. My tightening torques are, 5 Nm Solenoid plastic housing 12 Nm Valve body screws 35 Nm Accumulator The result is 6.5 bar in VCDS. I know the accumulator is low torque but I wanted to see how it changes so I hit the accumulator with somewhere between 45 - 50 Nm. This time I get 9.5 bar So my question to you, sir, is if you believe that I can achieve the needed pressure if I go to 70 Nm with the accumulator or if there is something else that's going on or needs to be tightened? It's just really scary for me to apply that kind of torque to that flimsy looking aluminum housing. I feel like I'm going to break it.

Is the pump running freely and to the right RPMs? Perhaps a bad or worn pump? As for the torques, I usually do it by feeling, as I never really found decisive torque settings... surely they are it there somewhere though...😊

☺️ 👍👍👍

​@LMAutoRepairs I want to ask something my dq200 give me code p177f lowe voltage motor not coming on again my research say that I must replace mechatronic tcu I was thinking I can I use a 3 phase controller to control the motor to build pressure. Because once the tcu detected pressure it will work ?

@ricardodavis9972 Doubt it will work... As the tcu will not not be able to control the motor and most likely will throw faults for it... Check powers and grounds... Make sure the controller is getting a good voltage and current feed... 👍👍👍

@LMAutoRepairs when I remove mechatronic cover after remove the oil with key on the motor only pulsing like it want to spin but nothing more no matter I do I just bought this car vw golf estate mk5 2009 battery is brand new I teat all the wiring at the connection everything is OK tcu is picking on my scan tool

What is the voltage readings of the motor on live data? Could be a bad tcu...

I didn't really announced it this year... Next time! 👍👍👍

They are the cheap ones, but I have replaced the wires, just keeping the alligator... I know the original ones are crap... 👍👍👍

What? Buy comments? What are you talking about?

Which programs are you talking about? 👍👍👍
