Default A5 S Tronic gearbox fault

I have intermittent gearbox fault that flashes an error for a few seconds and then disappears. I plugged the car into my solus computer and it gave an error code of 8040-P17D8 ( torque limitation due to clutch temperature ) I ve been told there is a technical service bulletin out for my year and model regarding this fault. ( TSB number 2022497/18 ) I can't seem to lay my hands on this though but I am told the repair is to replace the mechatronic ecu bord due to a known problem with it. Please could any shed any more light on this problem or even post the tsb ?

Default Cheers for ur help audi users !!!!

To answer my own question, yes there is a known fault and yes there is a tsb out from audi for this very problem. It basically involves removing the mechatronic unit and replacing the circuit bord which is approx 300 rather then the 2500 for the complete mechatronic unit. Although my car was out of its warranty period. My local audi dealer was prepared to give me a good will contribution towards my total repair which was 1200 which in the end only cost me 230 I am please to say I have a very good local dealer. However this was based on the fact my car had a full Audi service history and the fact this was a known problem. Keep up the good work Audi Leicester. 👍, cheers Audi users I don't know what I would have done without ur help.......... 😡
