Audi A4 B6 CVT GEARBOX TCM REPAIR
Vložit
- čas přidán 7. 09. 2024
- This is a common problem for all Audi A4, A6 2001 to 2008 (B6 and B7) owners, who have a car with automatic continuous variable transmission (Multitronic). After using the car for a few years the transmission control module gets faulty. Approximately in 90% of cases the problem is that some of TCM sensor's aluminium wires are broken and there is no electrical contact anymore.
When this gearbox TCM fails, it will normally start with the “PRNDS” light flashing on the dash when driving instead of just the “D” symbol. This fault will normally start out as intermittent, but always becomes more permanent with time. When the “PRNDS” light comes on, the gearbox will normally go in to fail-safe mode and lose power. Other common symptoms include complete loss of reverse gear or no drive at all.
This video will help you to understand, how to fix TCM by yourself and save your money.
All you need is a special soldering flux for aluminium and a good soldering iron.
Here's a list of fault codes that could be caused by this problem:
17090 - Transmission Range Sensor (F125): Implausible Signal
17106 - Transmission Output Speed Sensor (G195)
17114/P0730/001840 - Gear Ratio Monitoring: Incorrect Gear Ratio
17134 P0750 Shift Solenoid A-N88: malfunction - Value of resistance too great.
17137 P0753 Shift Solenoid A-N88: electrical - Output dose not have a contact short to earth
18201 - Transmission Output Speed Sensor 2 (G196): No Signal
18226 - Pressure Control Valve 2 (N216): Electrical Malfunction
P1818 - 007 - Short to Ground - Intermittent - MIL ON

This is great. Shows what can be done with a minimum of tools and money. People don't always realize what's behind the $2k repair job at the dealership. Thank you. Great video.
such a professional tools ....
Good stuff!
Great video and very helpful. Thank you.
Hello kristaps Priede do you know how to remove the special thermo and vibro gel?
You need to use non aggressive alcohol. I think it was Schwegmann 8809 Cleaner z, but I'm not sure.
Thank you so soo much. Wish u all the best.
Juan, did you check the main tcm connector? There is no mechanical damage on it? When you did the soldering, the alluminium wires should not touch each other. It's really tough work these wires can be easily damaged. I suggest re-check soldered wires. Sometimes they look, ok but there is no contact.
So if you mean only TCM repair costs there was approximately 10€ for soldering flux, 5€ for epoxy glue. The soldering tin 5€, silicon is no need to use, with epoxy glue it's already hermetically sealed. But I want to draw attention to the fact that if there is different damage than this, repairing costs could be more expensive, there are some guys who do repair service starting from 120€ to 300€ per unit. Also i want to mention that when you do this repair you need to be very careful, because it is very easy to damage other elements.
Sveiks! Remontejat blokus?
Hi Kristaps, I also have this transmission control board problem. A few wires came off and when I tried to re-solder them in place, my tin/lead solder didn't stick to the terminals!! However, after watching you re-solder them I noticed you kind of struggled a bit, but somehow you managed to get the job done with that secret flux of yours. I'm using Alum solder from Poland, supposedly for this type of job.
I have a few questions for you if you don't mind answering:
1. I got a hold of 99.3% tin, 0.7% copper solder now but I still have problems on my "test" pieces of aluminum. What type of solder did you use?
2. I have tried from 240°C up to 350°C iron temperature. What temperature did you use in your iron ?
3. I also filed my test aluminum pieces. Did you use that small file you were holding in your hand for that reason, too ?
I have cut small pieces of aluminum off a heat sink trying to mimic the size of the terminals where the wires are connected to. This is in order to practice. I've been able to have the solder stick to aluminum foil, but I have failed miserably to have solder stick to these small aluminum pieces.
I look forward to hearing from you soon, and thanks in advance for any input you may provide.

Hi, the problem is that aluminium very fast oxidize, thats why its not soldering. Main issue is right flux, I used one made in russia, there is written on it flux for aluminium (Флюс для пайки Алюминия), For you I suggest to try different flux the soldering iron is not so important. On the market there is a lot of fluxes, but there are only few which works.
Aren't the plates made of copper and soldered with tin?Isn't an ordinary soldering iron possible?
Broken wires and connection points are made from aluminium, it could be different in newer cars, you can use ordinary iron if it heats up enough and you have the right flux.
Hello, the erro was the sensor f125 implausive signal. If the person who has experience welded.
Hi. There is a smaller covering that looks like it could also be opened. Have you tried opening that too?
Ameera Arendse No I didn’t, I just repaired damaged connections.
Very helpful 👍
did any one try changing out bad multitronic with a 6 speed tiptronic from same audi b6? only wondering is that posible and what do u need to do.
I heard that it is possible to replace to manual, but I don’t know about tiptronic.
@@kristapspriede7758 i change out mine from multitronic fwd to manual 6 speed quattro. now gearbox acting up again(grinding in 2 and 3). was thinking abaut buying a donor car with tiptronic quatrro and changing out again (i really like automatic, reason why i bought this car) but i m not sure abaut electric and what else do i need to do. mehanic is easy. tuwm for your answer. greetings from croatia
Hey Kristaps,
Excellent Video. I have a question for you. I have a 2004 Audi A4 Cabriolet 3.0L CVT trany. I search and found that the TCM is in the Gearbox. I don't many small to mid range jobs and I am a DIY type of guy. Question to you is, how hard is it to get to the gearbox and remove the TCM. Thank you any feedback.
what tools do you need to take the tcm out? Do you need anything to support the engine or transmission?
You need pruning shears, screwdriver, and a file.
How do you suggest I take that backing plate off? Should I heat gun it and slowly peel it up?
Hi, do you mean plastic cover? I used Dremel rotary tool.
@@kristapspriede7758 thank you so much! I’ve been replacing these on Audi A4’s with the cat transmissions but I’ve been using used ones so I have 2 spare ones. I really want to try to repair it myself and this video really helped me! Thanks! I was thinking to use a dremel but wanted to be sure first. Did you heat it up with a heat gun first? Or did you just cut the edges before slowly peeling it off?
@@oriamzepol Hi, no I didn't use heat gun. I just cutted edges with dremel.
do you need to do an adaptation after repair? using vcds or similar. mine drives perfectly for 10 mins or so then starts to shudder on idle as if it does not know what gear it's supposed to be in. then lunges forward on take off. prnds flash and error for reverse lights comes up. any ideas?
For me everything worked fine without adaptation. For u I recommend to read fault codes with vcds or similar tool. If error code is similar as I mentioned on video description, then it's probably the same problem TCM is faulty.
Hi, I had the same code as you and repair it by soldering the cables, but now the car does not recognize the tcm. You have some idea. I need help please
Hi, can you please send me your error code before you started repairing? Do you have previous experience in soldering?
I have audi A4 B6 2005
Trouble code 17090 could you please find out for me please let me know thanks 😁
Can I ask you a question? After u Fix did you need to scan tool? Or reprogram
I used a simplest obd2 scan tool and just cleared errors
Paldies Kristap, domāju šī vaina vai nē, bet nu esmu pārliecināts "same shit"
Dažs reiz pats pārlec uz S, kaut arī selektors stāv D. Pēc kā ieliekot N sāk mirgot visi burti, aizmugurējā ieslēdzas ar triecienu, būs vien jāver vaļā!
Sveiks! Ja ir iespēja pieslēdz pie kompīša nolasi kļūdas, bet izklausās tieši tāpat kā mana problēma. Esi uzmanīgs sačakarēt tur kaut ko ir pavisam viegli. Tie alumīnija vadiņi baigi slikti lodējas. Ja, kas dod ziņu ir viens džeks, kas tieši uz šiem specializējas pameklēšu varbūt varu kontaktus atrast, ā vēl to hermētiķi nevajag iekšā smērēt.
Kristaps Priede Kļūdas nolasiju, tā teikt klasika "P0706 17090" , kāpēc hermetiķi nevajag? Kad viedo smerejāt ciet ar nodomaju "šito otreiz ārā vairs nedabūt, na nu kaut kur nepielodejās" . Ar šāda veida lodešanu esmu nodarbojies (ABS blokiem) tīri sekmīgi, bet ja ir kas profesionāli pielodē tad kontakti noderēs )))
1. Kā jau tu teici, ja kaut ko vajadzēs pārlodēt nevarēsi vairāk vaļā dabūt. 2. Hermētiķis ir uz accetona bāzes nav veselīgi skābe uz plates, oksidējās saēd alumīniju utt. skābe paliek skābe. Kad tā izdarīju pēc tam apsmadzeņoju, ka nav īsti labi tā darīt.

Hello. Do I need to drain the transmission for oil before i change the TCM? Or Can i lift the car in the back so the front tilt forward? Best Regards Lauritz
Hello! You don't need to drain oil. The TCM is accessible from the back, take off rear transmission holders then disconnect connector, take off transmission cover and TCM out. You will loose some oil while taking out TCM. When reassembling, oil leveling will be necessary.
Sveiks Kristap, man tāds jautājums. Ir tāda iespēja ka man dēļ šīs kļūdas nestrādā spidometrs?
17106 - Transmission Output Speed Sensor (G195)
P0722 - 35-00 - No Signal
Sveiks, cik man ir nācies saskarties ar spidometra problēmām, parasti bija aukstais lodējums uz paša spidometra plates. Piem. rezistoram viens savienojums atlecis nost no plates. Spidometru ir jāizjauc un rūpīgi jāpārskata. Ja atrodi, tad ar lodāmuru pielodē kā nākas un viss aiziet.
Sveiks, paldies par atbildi, vari ludzu iedot kontaktus facebokā vai watapā, es varetu rit viņu izskruvet un apskatities, ja kkautko nesapratišu varesi man iedot kordinates lai saprotu kur un kas man jameklē :)@@kristapspriede7758
But no display prnds on the display
Hey nice video, is there a way I can DM you with some questions. Have me an Audi A4 2005 sline and I need some advice. Thank You.
Escoban13 did this problem happen to u?
Yes I believe I am. I need him to message me @ brendelle13@gmail.com
Hi, Juan! Can you please send me your error code before you started repairing? Do you have previous experience in soldering?
Kristaps Priede Hi love your video thinking I'm having the same problem can you help me decode what I'm looking at

Hello Kristaps,could you tell me the name of the tools you used ?
Hello Vicky, please kindly see in description under the video. There are tools and links.
thank you
What is the part number on the TCM?
Hi, I am not 100% sure, but I think it was 01J927156 AH or 01J927156 AE Temic Hytronic VL300..
This the mechatronic?
It's multitronic
hi Kristaps, thank you for the great video. In my case at the begining it was the fault code 17090, I opened the tcm and there was one conector broken, I repaired but after the instalation of the tcm came the codes p0750 and p0753. To mention that its not the first time that I'm repairing this type of connection, 01j tcm is my first.
I opened one more time, and inspected again, all conections are ok, and that connection that i made was one contact to the n88 valve. I messured the connection it was ok.
Do you have some idea, what was not made.
p.s. I fill new oil, multi cvtm from motul.
Hi, Gor. I think it is possible that during the soldering process you overheated the connection, so it came off on the side of the chip board. I suggest recheck that. Maybe now there is bad connection.
what is the name or type of wire and flux to use
Didn't this video used to have audio of you talking and then some nice piano music while you were soldering? It was better then.
Hello Jerry,
That's true, after editing sound crashed so now it is as it is.. At the moment it is not possible to get that previous version.
