Hi
In this video I will take you through the dismantling and re-assembly of a mechatronics unit from a DSG 7 Speed gearbox.
The unit was failing to build pressure, making the car to jump out of gear, and throwing a P189C and a P0841...
I have mistakenly, gave some inaccurate torque settings for some steps, watch the video fully, as I will correct myself later... also, this torques are just my own feel, as I don't have any credible sources with the torque settings for this procedure...
Feel free to share it if you have them...😉

Hope you enjoy the video.

Like always, thank you for watching! - ยานยนต์และพาหนะ
Thank you so much for this video. I had a P17bf fault but like you when I dismantled the mech I could not find any obvious reason for the fault. I replaced the accumulator with an aftermarket one and then replaced most of the seals as per your video. The hardest part was getting the clutch actuator sleeves out. I ended up putting on a latex cleaning glove which gave me more purchase on the sleeve. All back together and working a treat, no faults and pressure is correct. 👍

That's great!

Good afternoon Luis,
Excellent detailed breakdown of the steps for repairing / servicing the DQ 200 followed by clear explanation.
Enjoyed watching every minute of the video clip. 😊
☺️
Thanks!
👍👍👍
Great great video Luis. I put mechatronics together in my office with the door closed because I get disturbed very easy. No joke and I have forgotten O rings.
☺️🤪
It is easy to miss things...
👍👍👍
A master class again Louis,and I hope you had a good catch up at automekanica (apologies for spelling lol) 👌
☺️
Thanks!
Yes, was a nice day...

Hi Luis another great video the detail is great good information see on your next video 😊
☺️
Thanks!

good morning LUIS thanks for the video i have a vw with dsg so much appreciated just in case
👍👍👍
@@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
Great job, thanks for this video.
☺️
Thank you for watching!
👍👍👍
The correct torque spec for those inside are 5nm +1/4 turn. This was found in the DSG repair manual.
So do you mean those 20 M6 bolts inside?
Hi La Auto thanks for your help my Audi A5 oil level sensor was broken in the oil sump tank that was giving false readings and no oil was leaking but I did find out that the car was smoking very bad till oil level reset it self and stopped smoking put in catalyst clean and dpf clean

Excellent video. What brand kit did you use and where did you purchase it? I see a lot online.
Hello sir! You have done a very good and explained video "webinar" ! Do you have a link for the repair kit you used so we can also buy because there are many "repair kit" from different shops and the quality isn't sure if it is good ,and your kit you prefer shows good and quality and i want to minimize the chances buying a not good kit and i will appreciate if you can sare the source you buy and buy the same! Thanks in advance!!
Great vid, as always. Where do you get your repair kits? Presumably you go for the more expensive ones - about £150?
Can't remember how much it was...
👍👍👍
Wow that was so cool!!
☺️
👍👍👍
Great video 👍, good work 🙂
Thanks!
👍👍👍
Great video, very helpful. Thanks!
One question - you said (at 36 mins) that the screw + washer that goes into the valve body (assuming it's not there in the new one) has a spring and ball bearing behind it but when I removed the screw on my old valve body to move it to the new one there was nothing in the hole. Is that right?
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!
Very interesting video!

Hello
Is it possible to book in audi a1 2012 with gearbox problem?
Dsg.
Many thanks
Very helpful 👌🏾

👍👍👍
Can you fix tcu units on this mechatronic?
Great video as always, many people hear dsg gearbox and decide not to buy those cars .. rebuild kit must be expensive plus labour and stress at first test, It's high mileage on this car? Obviously regular oil change will extend life...
Can't remember now...
I might have shown the mileage on the other video...
👍👍👍
Helpful vedio as always

Hello Mr Luis , nice video as always , problem solved ... but we still don't know what caused this pressure problem , this mistery will remain unsolved , like Lochness giant monster...
😅
Kinda of... yes...
👍👍👍👍
Top Video
Thanks!

Hey, i have a virtus and It got hit underneath due to which one of the engine mounting came out and merchantronic was leaking a bit ( no facial or engine damage to car ) Now they will change the Merchantronic. And concerned parts.
My question is will i be facing any issue or it will be like new If they change the whole part ?
Onlt damage as of now merchantronics and excel leaked.
If they replace the mechatronics and not other damage was inflicted to the gearbox, should be ok...
👍👍👍
Luis could you share which pins you connected when you tried to benchtest the Mechatronic? I ordered VCDS cable and would like to benchtest it before assembly since my Mechatronic is still failing to build pressure after rebuild (the pump runs continuously).
Just google "dq200 pinout" and you will see the connections...
👍👍👍
@@LMAutoRepairs
Thank you sir 🙏
hi mate fantastic job were did you buy the kit from
eBay... if I recall correctly...
👍👍👍
Great video! My car has the same problem, i think is the plate. Can I ask you how much do you thighten the screws of the pump?
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....
I just want to see if you can change the oils on DQ200. The dealerships says you cannot change it without taking the whole unit apart.
That's incorrect...
You can change the hydraulic fluid without removing the mechatronics...
👍👍👍
Nice
☺️
Thanks!
👍👍👍
There was a recall in 2013 to change from synthetic oil to mineral oil because in very hot climate countries there was a chance of causing shorts on the circuit board. Also before the recall the oil was supposed to be for life. After that you have to change it every 40K miles/60K km.
☺️

wow,very good video..is possible help me to find a Nm of screws ?? for connect with VCDS is only connect to bus of dq200 ??
very thanks for this video
Yes... CAN high and CAN low...
👍👍👍
@@LMAutoRepairs and for Nm ?? Is possible send me your email or WhatsApp on pm ??
Insigtfull vid tahnks .... but did the car end up working ? And how do we sot if the tcm is dead
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 😝
hi sir, would you mind share the diagram to connect vcds to mechatronic as shown in video? refer to minutes of 45.00
Thank you in advance.

Hello, excellent video! How do you remove the fork selector cilinders? i am having issues removing them and i dont want to force anything.
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.

Hi Luis - Great video buddy.
My vehicle 2011 Golf TDI is throwing a 17252 error code, what could be the issue?
It changes gears on higher RPMs...around 3800-4000 especially from 2nd>3rd. However, everything works properly on demand by shifting in manual mode.
I have replaced the filter and oil but it is still doing that. But I haven't driven it much since then.
Also, would you know how I can clear the error code?
Thank you in advance.
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!
Hey man. I have a dq200 7 speed my car isn't going into reverse and making a lot of noise only in reverse but in drive gear it's working smooth as butter can you give me some suggestions as the people at VW told me when they scanned the error was in mechatronic
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...
👍
I have a DQ200 DSG SKODA 2016. Only code came up is P17BF00. Mechanic is sorting out the mectronic but now saying the TCM is gone to. I have no symptoms and it drives and changes gears perfectly. Only problem it lights up and says gearbox error once a day if that.
What do you think? As now it’s costing me £1400 as originally was £800.
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...🤞
Hi,
I got used dsg gearbox vw golf 2.0 gtd 2016,, same metronic from my old dsg gearbox, fill up gearbox oil, around 6 litres, not going in reverse and also jump in drive gear too, I code up p271100 unexpected michanical. disengagement,?
Thank you
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...
Hi mate have got same problem mines running at 36 bar still drives fine though how long would it last if i kept driving it ?
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
Mine said loss in connection in transition module. The car would not start
I am having this problem now, the mechatronics was replaced but now after 1 month it is back going in and out of gears whilst i am driving and especially going over humps. Can you help me
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
Good Afternoon Luis, I from Malaysia and have a DQ200 gearbox and I meet some problem now. when I driving the gear will turn to nothing and I cannot run aways my car. after that I need restart back the engine then just can continue driving. what is the problem?

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
I have had this issue in Seat Arona 2022 .. It is again Mechatronic and found it leaking oil.. It is extremely expensive
I had to get a VW genuine Hydraulic oil and I replaced the oil and it looks fine now, but at least I need to change gasket to stop the leaks

Good morning Luis. I have a question. Can You virginise KIA/Hyundai ECU SIM2k-141? I need it for my private car for diagnostic purpose. Best regards.
Any fix on the p1707 code please
On the 7 speed dry clutch?
nice to see you work in this but i would ask aqusetion how i check pressure acmoulator with thanks im your foller from iraq
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 Leo,great video,s, love the content,keep um cummin ,a question if might ask about some thing not relevant to this video,basically had to replace my engine ecu as was intermittently causing engine failure by way of detination,I have a forth engine to replace 3rd that's still in the car ,so have replaced ecu, uch,steering lock and key card ,o lying problem is not opening hatch other than that all good,used clip to go to uch access setup,scrolled down the list,tailgate is in the list,but says absent,all others say with or with out,is there a way of sorting this problem out it's a reno scenic 1.5dci 2005 with the N2 uch,any help or advice welcome,using car at moment with boot locked thanks
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...
👍👍👍
Unfortunately the driver and lack of knowledge of these dsg/ getrag powershift gearboxes is the main problem . Once a driver understands the workings and maintenance involved, they will then full appreciate it!
☺️
👍👍👍
Did you really put 70 Nm on the accumulator? When I disassembled the Mechatronics I could remove the accumulator by hand. I wonder if it is possible that it screwed itself out and that caused the loss of pressure 🤔
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...
👍👍👍👍

Hey Luis,
I'm having a hard time with my rebuild. Is it possible to get a paid video consultation from you? Something like 30-60 minutes. Alternatively you can pick out some stuff from your wish list you'd like to have.
Could really use some help right now. Thanks :)
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...😊
good work but 😭you talk so so much..love you ❤️
☺️

@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...

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