Have a 2001 A6 2.7T tiptronic and this came up, I think twice. I had some cat codes coming up and don't know if this just came up the once or if it came up twice. What does this mean and am I going to have to replace this? I see from some searching on here it is a big ticket item.

I haven't really noticed anything on the peformance as far as when it shifts between gears. Do I have to actually notice a problem before this is something to look into?

Youknowho

I just had same problem. i droped my a6 at the auto shop and had them chance the fluid and filter. got about 20miles so far so good no more engine light

Malfunction Indicator Light (MIL) on, DTC 17125 (Torque converter clutch circuit performance or stuck off) stored in transmission fault memory.
This is caused by torque converter internal oil seal failure.The torque converter must be replaced as the seal is not replaceable. Good news is if your car is Audi Assured or if you have extended warranty, it's covered. If you need more info let me know. I in ATL

I had check engine light on for my Audi A6 2.7t, 20000. I took to one german mechanic, he ran vag-com and found P0741, torque converter clutch problem. My mechanic is asking me to sell the car, which I dont want. Please advice me where can fix? how much it cost? do I really need to change my transmission? or any other fixes solve this problem.

Just had my 2001 A6 fixed for the same code. You will notice your gas mileage drop (mine went from 23 highway to 16 while on a trip across the country) and if you are lucky enough to live in a "smog check" state, it won't pass with the code because of the lower mileage. You can tell if it's happening by reaching highway speed and then accelerating a little. If the tach goes higher but speed does not, it's not working. I went ahead and had a rebuild done, because the car still runs great and the death of a tiptornic can be expensive. Cost me $3400.

I have the same code and though I cleared the DTC before but it returns. What is interesting is I have logged the clutch slip and whether/how it is locking and engaging through VAG, compared it with other Tips and studied the log a bit. I know for sure that the TC clutch closes on the highway and the slip numbers all around look pretty decent and comparable to healthy Tips. My clutch doesn't lock up much if ever while driving around town. I need to replace the fluid and filter though. My mechanic saw small metallic flakes floating in the fluid (ouch) and recommends me not to drive cross-country anytime soon =/

Would be interested in seeing even more VAG logs of the Torque Converter Clutch, Slip speeds and related info from both those getting this DTC and those who have healthy Tips.

are you really asking if you can buy a warranty to fix a problem you already have? who in their right mind would do that? you need to sell your car and take the bus. you are to dangerous to be on the road. stupid people shouldnt drive.
