I wanted to come back to this video and say thank you. My TCM lost communication and all three lights went on. Engine, traction and TPMS so I used my OBDEleven to verify that there was no communication. First thing I noticed is that it wouldn't shift at all. After watching this video, I pulled the seat and base frame, opened the passenger side wiring loom plastic case and EXACTLY where you shower lay three wires separated and apart. I spliced them together and taped it up and re assembled, all codes are gone. One thing I wanted to point out is that my carpets are very dry on top, but once I pulled the carpet up to look for the wires I was shocked at how much water was being held by the foam underneath. Which also means the drain plugs on both sides and the a/c drain plug all need to be cleaned. Even though I got the car working 100%, there is still the drains to unclog. Thank you for taking the time to share this fix!
You're very welcome and thank you for your feedback, I gain absolutely nothing by making these videos but I feel good reading comments and seeing LIKES because I was able to save a good amount of $ for someone.
@@pandydiy you saved me $900 for a TCM and most importantly a HUGE mistake in buying it. The wires were my issue not the TCM itself. What's even better is my 2014 TDI is not post dieselgate modified, so it shift nicely and feels strong. I had a 2013 that went thru the emissions recall and the difference is very noticable. When I saw your wiring loom I was thinking "no way I am comfortable slicing all the way up the loom to find that junction." What I didn't realize was that the loom is fully exposed under the carpet and protected by a plastic case. It was much easier than I expected! You are helping a lot of people, and more to come as the cars age and this becomes more prevalent
Same thing happened to me, kids left a huge water jug on my floor and it leaked about a gallon of water into the harness. This video saved me hundreds (if not thousands) of dollars at the Audi dealer!!!
@@jerrywang3590 I had to pull the passenger seat and trim, from there it wasn't bad. Had to pick up the tool to remove the seat bolts, looks like a Torx but it isn't.
PANDYDIY. I have a 2013 Q7 with the exact same issues you had. Sure enough I checked the wires from the TCM and they were corroded. I cleaned them up and soldered the wires now the transmission is working properly. Thank you for taking the time to post your video it was very helpful and saved me lots of time and money.
Thanks Bro. I had the same issue. I located the wiring after removing the seat and the carpet. I found a corroded pair-to-one wire. I clipped the ends then twisted them together and like magic, or the grace of God, my truck was able to shift out of park. I know you saved us thousands. Be careful tho, Audi wants to charge thousands of dollars to locate and solder this wire and you're messing up their money. 😀 Thanks again sir!
Thank you very much for making this video. I was 600Km from home this weekend when this happened. Thankfully, I had my VCDS cable with me. A few hours later, after finding someone with a laptop and a quick trip for some triple squares, I had it all fixed. Again, thank you!
Just wanted to say I have a customers 2012 Q7 with 90k miles and it had this exact failure. No communication with TCM, no start, couldn't put into gear. Started having intermittent issues on customer. Tow truck driver was even able to load and unload but when I went to pull it in it would no longer even start or come out of gear. (other than the override method but would not start)
Thank you soo much!! This video help me fix my 2013. Didn't even know I had a water issue. Sure enough the connection was broken. Thank u Thank u thank u
Hi, unfortunately I have experienced the same problem, the water leaked into the car throught the roof. The engine starts, but I a have no respond from the following modules: -Transmission -abs -airbag -air conditioning -Electrical installation -phone -Pdc -The comfort system -rear climatronic -Rear door -Passenger door -Comfort systems 2 Any idea how to fix it? (or what should I start with? ;) The car is 3.0 tdi 2006 automatic trans. Thank you in advance for any advice!
Check the same wiring that I check on the video, if your carpets are wet then thats a sign right there, located your TRANSMISSION CONTROL MODULE AND START CHASING WIRES FROM THE MODULE, make sure the wiring from TCM to the rest of the car is not rotten
Hi, can you please tell where the gateway is located, I need to access the extended CAN bus of the vehicle to get radar sensor data. Is there any y-connector available so that I can use it instead of destroying the insulation of the copper wire of the CAN bus ?
Just had exact issue, including poorly spliced wire and leaking in my 2015. Why is this not a recall? Paid out of pocket for a tow truck plus several hours of shop labour
My Polo has U111100 and 01315, gear letters are not showing on the dashboard, the lights at the gear stick are not illuminating and the stick cant move either, sometimes when i want to start the car it won't start, it says --P/N yet the shifter is in park though it is not showing on the dash, at first there was Check engine, Traction and ABS, after fixing the loose terminal the check engine light is gone but the ABS and Traction are still there and still the gear won't show hence can't drive the car, what could be wrong
I have a 2010 Audi q5 that won't shift to drive. It stalled while driving and died in gear. Now it won't come off park. Im thinking there's no power that module. Hopefully the location is the same for the Q5 as yours. I'll update
The problem was bad resistance where the ECU is connected. TCM was only getting 6 volts. We jumped the fuse using power probe and bam it worked. So now i have to clean all the corrosion out from the box. Stupid design of letting water accumulate anywhere near the ECM and power to components.
When I saw the video 2 weeks ago the car was only shifting erratically upon start. But one week ago all of a sudden I got the exact same issue, tpms, esc warning lights came on and car lost transmission to the tcm.
@@pandydiyhey it seems I can just pull up the carpet to expose the wires and fix them from there. I was able to slip the carpet out of the sill plate. But don’t know how to get it out from underneath the vertical trim piece by the door. I noticed you had it removed in the video how did you do it? Thanks
I’ve got a u0101 error code. 09 Audi a3. Fuses and relays are good no crank no start. Car starts if I jump relay for starter. Power is going to the tcu plug. I unplugged it from tcu and oil came out mech unit. Tried to clean. No luck. P flashing at selector inside car. I have a mech on order but want to be sure before I fit it. Maybe I should check full wiring loom
@@rodneygriggs1747 yep it was the Mechatronic unit. Ordered it on cascadegerman for the best possible price and installed it myself and readapted it with VCDS! there was no other solution for it. The trans brain was dead
so being my gear shifter isnt coming out of park, the TCM module under passenger seat your saying is the problem where the wires have corrosion fix those and the vehicle will then allow me to shift from park to reverse neutral drive etc ????
@@pandydiy But i haven't had any water collect down in the floor board area as you had shown in your video on the matter and issue. When i started the vehicle with shifter knob off i was able to press the brake and it came right out of park no problem. does the vehicle allow you to take it out of park without any power supplied which energizes the system for that purpose? Or the vehicle MUST be started to which power is supplied permitting the vehicle to be taken out of park? somethings not right there maybe its the switch in the assembly i dont hear any click sound or nothing. I use the push start button way to start the vehicle. The shifter knob button doesn't stay pushed out, it stays pushed in for some unknown reason. Thats why i am leaning more towards the shifter knob being faulty/defective and nees changing its got me sorta stumped lol..i can't be over thinking this i dont believe ..
hey. My transmission shifts erratically. I tried using Manual Mode to control the shifting. But still when the car is cold, it could go from M2 to D to M4, then M3. I suspected an issue with TCM. but couldn't figure out what could be the cause until now. So it seems water damage can cause loss of tcm communication with the car. But can water damager or moisture cause the TCM to send wrong instructions to the transmission? I did find a lot of water under my passenger side footwell. Thanks in advance.
I would start from this wiring issue here, if wiring is good then look for other possible issues, fluctuating voltage can cause all kind of issues with electrical systems
hey please tell me, the car was starting, or because of the wire it wasn't starting, I have a Q7 and it won't start, it stopped suddenly and won't start again
I have a 09 q7, its issue is it will run correct for 2 min then automatically shift its self as such at idle....D1,D2,D3,D4,D5, then i get gearbox malfunction message with tranny lockdown. I am just curious if this is familiar at all to your symptoms.
I feel like it's a solanoid or my trans is dirty and keeps clogging the screens. I can clean the mech then run it flawlessly for about 20 miles then it pulls the same shit.
Does this lead to no crank? As when scanned mine said TCM no communication. But mine the gears can be selected when the switch is on. Am thinking if because of the TCM the car will not start. Thanks
Make sure your shifter is on PARK OR NEUTRAL when you're trying to start the car, if the car thinks that the car transmission is in DRIVE OR REVERSE then that would make the car not turn over
@@pandydiy thanks for the reply, it is in park and won't start. So its unlikely its the TCM fault right? If the wire corrosion is bad would it not cause it not to start?
Can you or someone explain how to remove the carpet properly? I can’t figure out how to remove plastic door sills or kick plates. My carpets are soaked
Had to tow it, but I’m in Toronto and we have caa so the tow was free. It was a pain in the ass because my car is underground in my condo parking so the tow was very tight … but yes specialized mechanic that deal with Audi/volkswagen, they’re fantastic. Essentially parts of the wires have corroded from the moisture and water and that part needs to be cut and cleaned and covered and put back together sort of like the video suggests. My mechanic said he had the exact problem on a Touareg the week before me too
Hey thanks for the reply. I finally found the corroded wires. Was looking for some thin wires. Took me some time but finally saw them. They were thicker than i expected. The three wires were in some kind of electrical wrap. But not the rubberized type. More like some cloth. I don’t believe it’s water proof. The connection was covered with green paste then dust after I blew dry the wires. When I tried to open up the connection the wires simply broke. After I was done with taking them apart I didn’t find any copper strands left. They were melted away or something. There are two burnt holes on the cloth. I suspect at one point the wires came apart and caused a spark and burned the cloth. I had to strip the wires. Because of that the wires are now shorter than they used to be. I couldn’t splice them together. So much trouble with the fix. But I think I am getting close!
Was able to manage to get the carpet out from underneath the trim pieces. i thoroughly dried the area where the wiring sleeve and wires are. unfortunately there is still no communication with the tcm. i left the sear in place as i am not sure how to remove the seat base. next step is to cut open the sleeve and look for any connection issues. The exposed wire are all one piece i dont see issues. But did notice some green color on the sponge next to the blacking case that holds the wires. So there must be some corrosion.
Check video at 1:40 there is 2 red power wires coming put which along the way join into 1 wire only, my corrosion was at the joint where double wire became 1.
