What code did you have, and what code is the new one?

@@arnoldca8377 I had a transmission code NJM and the new one is NLQ

Thomas and V10DTDI, wondering if either of you have seen codes " P1689 - 000 - Implausible Message from Elect. Load Controller - Intermittent", " P1862 - 000 - Missing Message from Instrument Cluster - Intermittent", " P1867 - 000 - Missing Message from Steering Wheel (J527) - Intermittent" Found these 3 codes after I noticed a quick flash of the EPC light ( I think, it happened so quick it was hard to tell) 2008 mkv GTI, I was going through an "S" turn fairly aggressively and the car pretty much lost power for a split second, I thought it was traction control at first since i had just done some ABS work. Other than this one event, car is fine. Leaning towards bad connection/loose since I was cornering hard... Any ideas or experience with this? VCDS measuring blocks to graph while logging data? Thanks a ton! Great vids from both of you guys!

V10PDTDI

cause of the bearing?

Hi I think you should make sure they are the same code and you can check with your local VW dealership with both serial number of both car and ask if they would interchange.

@@V10PDTDI This gearbox is together with the corresponding mechatronic. I am not changing one mechatronic to another box. So it should be possible if I do a complete gearbox swap plus the mechatronic?

Wow. How did the car catch fire?

Brian Mccormick what I found is the gears had wear on them.

Hi the transmission wasn’t working properly and if I remember right it also had some fault codes but I can’t remember what they were then we ordered a new mechatronic but sadly the amount of metal stuck on the old part prevented us of installing a new part into this transmission so we had to put a used one in and the car ran fine for quite a few months after but I learned from the customer that it had a under dashboard fire and the car was totaled

If there is that much stuff that falls out of the filter when you remove it, then you have bigger issues. The filter is designed to capture the fine partials very well that accumulate under normal wear from regular use, and should not fall off when you remove it. The DSG transmission is supposed to be serviced every 35-40,000 miles. Due to the complexity, and the various sensitive speed sensors and actuators in the Transmission and Mechatronics Control Unit, I personally change the Fluid every 20,000 Miles/2-Years (Whichever comes first), and the filter itself every 10,000 Miles/1-Year (Whichever comes first). Is it over doing it, maybe, but these Dual Clutch transmissions are very costly to repair or replace. Depending on the issue, there is not much serviceable parts in it. The Mechatronic Control Unit is around $1,000, the Dual Clutch Pack Assembly is around $400, The Entire transmission Assembly itself $5,000, or even the Dual Mass Flywheel, which is around $400 (This part is technically not part of the transmission itself, but it is a higher than normal failure rate than most other types of transmissions. I have seen them fail in as little as 20,000 miles, but for the most part they can start to fail at 80,000-120,000 miles). VW will only replace those items I listed, or the entire transmission assembly, they will not go deeper into it. I have the correct tools to fill the transmission, and the scan tool/software to monitor transmission fluid temperature to properly set the fluid level. So for me to do a DSG Fluid and Filter Service, it costs me $83 for 5 Liters of Fluid, Transmission Filter, Filter Housing O-Ring, and Drain/Fill Plug Seal, plus the hour or so time/labor to to the service. I use only OEM VW/Audi parts and fluid. The Factory fluid on these transmissions is Pentosin. The Part number for the Pentosin DSG Service kit is #8038207-KIT I have worked on maybe 50-60 02E DQ250 DSG Transmissions, and the biggest cause of failing parts is improper care and maintenance. Some people had 80,000+ miles and the transmission has never been serviced. If you service them every 35,000 miles, don't use Launch Control and shift at 6,500-7,000 rpm at every single stoplight trying to race Grandma in the next car over, they can last 300,000+ miles, even behind a Stage 2+ K04 engine making 350 Hp and 350 Lb-Ft of Torque at the front wheels (400-Hp/400-Tq at the engine). With a proper DSG Tune from a reputable company such as Integrated Engineering, APR, or Unitronic, the clutches will hold up to 450 Lb-Ft of Torque coming from the engine. Tho, anything really over 400 Torque at the engine, I would highly recommend a High Torque Clutch Kit. These transmissions are very well built and can hold up to some serious power levels. With the proper high torque clutches, and a DSG Tune, they are holding up to 650 lb-ft of Torque at the wheels, which is roughly 700 Lb-ft of Torque at the engine. That is really the max of this transmission and is now limited by the strength of the transmission case, gears, shafts, and overall fluid dynamics of holding the power.

@@1badk20 drivers don't care, they simply crank the car and into the road without letting them warm up. Drive the car fast even when cold, clutch packs need hot fluid for proper engagement and lubrication, just like an ATV transmission, when cold they do not bite, once hot the transmission works, but need to let it warm before getting on it. I see it always, start car cold and immediately doing 60mph fast, causing damage to discs.

Hi I have taken the transmission apart and there was a lot of wear on the gears themselves.

+V10PDTDI Did you film the teardown?

+V10PDTDI Do you plan on posting a video on it and what exactly was the issue with it once you took it all apart? Thanks

Abuse or possibly not performing proper maintenance.

I’m not sure about a 100 % new one that was ordered with the serial number it might be plugged and play but it’s possible that the coding would need to be changed to the same one as the old transmission. I never installed a new DSG transmission ever so I’m not sure.

Also if it’s a newer car you might have to deal with components protection I replace a transmission into a 2015 Audi S3 it was a used part and I had to use the factory VW and Audi scan tool to unlock the transmission because it would not work unless it was done. Then again I don’t know what would have happened if it had been a new transmission.

@@V10PDTDI so if they are used they have already been “activated” for lack of a better word? Thinking on going to the junk yard and taking off those plates to see if there are metal shavings as you demonstrated. Just want to make sure any additional coding is necessary to get it squared away.

Having same, did you find a resolution?

@@cha0zsprtin2 yes, long story short, DSG was bad, had audi replace it under warranty. I have a new DSG sitting in my garage cus the A3 quattro is now wrecked. After a short while of having that issue, the trans just went into limp mode

Best Software for Audi, VW, Skoda and Seat ist VCDS. After changing the clutches or mechatronic, you have to make basic settings on the DSG-Gearbox. In youtube are many videos, how to do that with VCDS, also in english.

@@fuppmanns_karel thank u for ur reply , i have VCDS i will give it a try

most of the bearings seemed ok but some of the gears had abnormal wear but you are right the metal shavings caused problems with speeds sensors on the mechatronic unit.

Dimche Zizo Hi when you order it from the dealer I think it already comes pre coded so it would just need to be installed and probably do a basic setting on the clutch. I never had the opportunity to install a DSG mechatronic but I did install 2 mechatronic on CVT transmission on Audi A4

Red Falcon He bought the core, i'm pretty sure we will see a video shortly

Hi I'm too familiar to this engine and transmission combo we did not get them here in Canada the engine has a timing chain ? And the transmission has a filter ? Or it is a 7 speed dry clutch transmission if it's a 7 speed dry clutch then I have heard of bad things about that transmission is you're check engine on or flashing when the car is not running right .

V10PDTDI hey dude what was the problem. The gearbox internally where there teeth chewed out lack of oil or bad oil change or was it the mechatronics which controls the gearbox shifts

John Yu Hi I can’t remember because it’s been a while since I did this car I think it still drove but the transmission would not work properly and I cannot remember if the PRNDL was flashing or not but I have presently a 2012 Golf TDI that the transmission is faulty possibly the Mechatronic it takes a very long time for the first gear and reverse to engage and there are fault codes 2 of them we are going to replace it for a used one because we don’t want to risk installing a New Mechatronic and it would not work then be stuck with buying a used transmission after that.

Ak Ak Hi looks like you’re transmission is very similar to the one in my video so when the mechatronic is removed or the transmission is drained from doing a service then there’s a big Allen bolt under the transmission and then in the same hole there a plastic tube that you remove in order to drain the transmission fully including removing the filter on the top so you put back the plastic tube then you need a special tool that screws into the place of the big allen plug and then your need a pump to push approximately 4.3 to 4.5 litres of DSG oil into the transmission the Mechatronic is exposed to the same oil as the rest of the transmission unlike the 7 speed dry clutch DSG it has two different types of oil the 6 speed has only one type that lubricates all the parts but if you have lot’s of time and patience you could fill the transmission from the oil filter housing when the filter is removed. Hope that this helps.

I also heard about a aftermarket dsg oil cooler. Would it bring the temperature inside the transmission down?

hi, did you ever find a fix ? im being told it’s the g182 sensor

ventolen I can’t remember but it all depends if the car needs a mechatronic or a complete transmission then it depends of the price of the used transmission.

Is this a 5 speed automatic transmission ? With a torque converter ? If it is it a Jatco Japanese manufacture.?

Yes you don't have to drain the transmission but the car could be lifted more on the driver side but in reality you will loose a very little amount .

thank you for the reply

Clifford Lebel hi I’m not sure I think that if you have the serial number from your car and the wreck car then you can check with your local VW dealer and see if they’re interchangeable but here is a link to a list of transmission were I found that list with the same code www.car-part.com/cgi-bin/search.cgi I tried the link that I gave you but it brings you to that web site but not the list I was talking about go from the start and chose the year and model of you’re car and then the item you are looking for then chose the right transmission code then it will show you a list of cars with the same code as you but I would ask for the vin number of the car you’re intent to buy and then check with VW to se if it’s compatible.

Did you find out if the transmission codes are interchangeable? I have a 11 GTI with LQZ code and would like to use a trans with a different code

No it was the same code so it was the same.

@@V10PDTDI so msy to msy, no need to reprogram?

Yes the metal particles are coming from the internal parts inside the transmission that is wearing faster than it should and then theses same small metal particles stick to any magnetic surfaces inside of the transmission and then premature wear occurs in the mechatronic unit then the transmission doesn’t work well anymore.שי שי

ProfessionalDad are you talking about the ones on the black metal cover in front of the mechatronic ?

Chia David Hi if I remember right you have to connect a diagnostic tool to the car and look a the ECU no. In the transmission section of the diagnostic tool a Rosstech tool works fine for that but I think that to be more precise you would have to call your local VW dealer with you're serial no. And then they can check to see what is the current part no. Also you can ask if there is any other number that would work the same I think there are after the part number some codes letters that identify the mechatronics and the price New at the dealer is around 1500$ Canadian.

Hi Alec, No, it is a Security Mode of the DSG. Is the DSG Oil Temp. over 160°C , the DSG goes in Security Mode and the PRNDS Display Flashs !

Cargofan How much would it cost for a shop to replace just the temp sensor?

Sorry, i dont know! You sure the the sensor is the problem?

Dustin Bubb hi no it just worked fine I don’t know if I was just lucky or what but it did work not long ago I also replaced the transmission in a MK5 r32 but it was also a used transmission but with the correct transmission code it worked fine I think in total I have changed only 3 or 4 DSG transmission.

@@V10PDTDI ok I have a 2013 va jetta gli my transmission went bat at 80000 got a used one vw told i would have to flash it didnt know if you had to or not never know when they are bull shitting lol

Aymen B Sami the metal particles seems to come from worn gears and the maintenance was supposed to be done at the dealer I don't know why this append because it's the only car that I had to replace The DSG transmission.

the TDI?

NICHOLAS LANDOLINA no it a 2.0 litre turbo gas engine TSI

sola sola are you talking of the black side cover with at least 6 torx head bolt ?

V10PDTDI I think it's called the transmission pan

Valeri Venkov hi I did not replaced the mechatronic at the end I had to replace the complete transmission for a used one I just erase the fault codes in the used transmission and then did the basic settings for the clutches with the VCDS.

I have no idea if this will be checked 3 years later but what did you end up doing about the p1929 issue? I have a p1824 code

@@jaredmiklaus5053was getting ridiculous quotes to have it repaired and the car wasn’t worth money, time and effort so sold it as spare repair. All the best

Yes I know better now. What I do now is I remove the small side cover to see and inspect the magnetic trigger when any see if there are some metal shavings stuck to this part it gives you a pretty good idea of the condition of the transmission.

@@V10PDTDI thanks mate, we all do now!

Thats what I gotta know ? do I mortgage the house ?

2k if you go to the stealership

Some of the gears were quite worn surprisingly.and all the metal particles made the transmission unhappy.

U solve ?

Yes it was plug and play in this application I use the complete transmission including the mechatronic it was a different transmission code but I think it was the same year car but different production date I don't know what other year and model you can mix match and it would work I think both transmission had the same gear ratios.

Pirat Pergan Hi I never posted the tear down of the transmission but I can say that the bearing seemed ok but the gear were extremely worn for the millage I don't know it it's just bad metals or what.

Lolo Stream It's very bad for any automatic transmission to engage and disengage the clutch while the car is moving at high speeds. Guaranteed metal on metal friction

Yes I did but did not have time to fix the video and post it but what I found is the some gears seemed worn but all bearings seem ok I don't know if it's a bad batch of gear set some of the look like new strange . The transmission was full of oil

+V10PDTDI I want to see the vid too, mine is doing strange things, like overreving when shifting and my shifterfork is making sounds. Very werid things.

MultiXZen late reply but I currently have a CC as well getting the megatronics unit replaced, I will let you know my findings but when I used to put the car in D it made that clunky noise and also at low speeds downshifting.

@@travisdeibert9474 is this clunky noise gone after changing the mechatronic? I have the same problems with my 2010 DSG on 170 hp diesel at 200k km when shifting down at low speed.

o koymparos toy giwrgoy hi I assume that you are talking about The DSG with the 7 speed with the dry clutch. If it is then I’m sorry but I have almost no experience with this transmission for us here in Canada we only got it on the Jetta hybrid and I only worked on one but i had seen video on u tube and it seems like a very problematic transmission what i saw is the mechatronic seems to crack and the pressure gets low and affects the transmission hopefully you find someone with more experience than me to fix your’re problem.

Maybe it's mechatronic

eM hi what I found is that some gears had unusual wear so the metal shavings came from gears the bearing seem normal.

V10PDTDI Thanks for the update

eM - did you check the differential .... From what I heard, they deteriorate and spread bits everywhere

Seecil Bard I was commenting on the video. I did a fluid change to my car with new clutch and Mechatronic, it only fixed the issue for 1 day, before the DSG kicked the bucket again

eM - ya I have terrible lurching when I first put the car in drive in the morning .... Did you ever fix your dsg?

:D it would grind into the moving parts and the little bit becomes not so little anymore :D

Jesús Guerrero I personally never seen a problem like that but have you checked if there are any faults in the transmission computer? Do you see the gear position indicator? Change from park to reverse to drive etc ...
