Audi A6 Quattro Check Engine Light Due to Faulty Torque Converter

(65 reports)

A problem with the torque converter can cause the Check Engine Light to illuminate.

Check engine light comes on, goes off, no pattern. Dealer and independent shop both state faulty converter, yet symptoms dealer said I would experience are non-existent. No slippage, no change in gas mileage or performance, nothing. I do not believe this is anything more then a sensor or computer problem. -
My torque converter started going around 80k, but around 100k it began to really act up and had to be replaced. Complete garbage service from Audi and this is by far not a rare problem, LOTS of user's have this problem and a class-action suit should be filed. The failure rate is ridiculous and there are many mechanics reporting faulty designs in the torque converter itself. The "joke" at an Audi dealership here in NJ that is owned by my friend's father and a partner, (Mr. Reynolds); Every Tiptronic Audi from 2000-2005 will need a torque converter and every car with the 2.7t (twin-turbo motor) will need turbos because of faulty designs. What a sick joke especially when his son said that to me after the fact I bought the car and had the work done, if I knew that then I would of never bought one. Like I said, I talk to the owner's son and other mechanics at Bernardsville Audi in New Jersey this is a serious problem. Mr. Reynolds is in partnership with another person and they also own and operate the Mendham Audi dealership. -
2003 A6 2.7T Check Engine Light on for 4 years. Codes point to faulty torque converter - No impact on performance and I have not repaired. Pain to get past Maryland emissions test. -
My check engine light came on & brought to Audi Dealer & they just told me I need to replace torque converter....I am in the market to buy a new car within the month & do not want to invest $2500+ dollars....the car has been running fine, no symptoms & after reading all the comments on this site I will NOT be replacing it!!! -
Po741 code came on took it to mechanic could not find anything wrong car drives and shifts great cleared code, came back on after about 200 miles. Not repaired yet. -
Check engine would come on and off for about an hour or so. Replaced the torque converter -
CEL after driving in snow - code states TCC most sites point to faulty converter... cleared code and it is back on within 20 miles. Just bought it and it's a fortune to maintain so far.... but that's the price for a good German engineered car, right? -
You all know the story. Check engine light came on...went to have the code scanned, yep...Error Code PO741 Torque Converter Clutch Circuit Performance … but it could also be a clog, a torque coverter clutch solenoid, etc. etc. bottom line is Audi refuses to help becase the transmission is sealed....about as sealed as our fates. I've heard others talk of a class action movement. I, for one, would do it. Where/how do we proceed? -
Haven't had it fixed yet so don't know cause of issue but the check engine light has come on and off since about 20,000 miles. Dealer just tells me to ignore it. Haven't experienced any engine problems as of yet. -
Code p0741 came on. Not fixed yet. I was told I need a new torque converter. -
Bad tourque converter! Weak from 1st, 2 gear took it to Jim Ellis Audi of Atlanta Ga. Said I will need a new transmission. -
MIL indicates faulty torque converter...not fixed yet -
MIL indicates torque converter -
check engine light was on when i bought the car at around 70k and still has not been fixed. -
Check engine light came on after passing 100,000 miles. Dealer checked it and said it was toque converter. After much researchand talking to mechanics I trust, determined that tranny and wheels don't lock up 1 for 1 at highway speeds. Affects performance, gas mileage and maybe emmissions. The tranny will not fail. I drove from California to Colorado last week and had no problems. I felt no slipping ever. My tack was near 4000 rpm at 80 mph. I don't know what it was prior to check engine light. My only concern now is Colorado emmissions test this summer. -
My 98A6 has had the same problems how can I get Audi Co in Asheville to fix it the car has multiple problems I think its crazy that there is so many problems with these cars all of the problems should be fixed for free!!!! Hello Audi my names David Bradshaw I am from Johnson city TN,37601 my email is davidbradshaw484@gmail.com -
I brought the car in 2014 with only 25,000 miles. So imagine my surprise the check engine light came on indicating a fault with torque converter! Except for the check light being on, there were NO signs or symptoms of any engine or transmission problem. I noticed that this problem occurs in Audi at about 90,000 to 100,000 mile mark (about 10 years of average driving), so it makes me think that fault code is rigged to go off at about 10 years? I know it sounds silly, but would be consistent with programing the fault sensory to indicate potential problem as well as real problems. -
Check engine light with P0741 code. Still driving but haven't repaired yet. -
Check Engine light goes on and off. Still drives and handles fine but I will not pay thousands to get this fix, will trade it in. -
