Hi,
For the Audi A8 code P0735 "Gear 5 Ratio incorrect" is a transmission problem and should be taken to a transmission shop that you trust. Have a good day.

clean your carb out

lock up control solenoid A B C is in fault causing your code that is inside the transmission most likely possible need rebuilt or used trans in if solenoid will not cure the problem

Sounds like the Catalytic converter needs to be looked at or replaced.

have the same code on my 2002 jetta with 1.8t. pulled the tranny apart on the car from the side tranny cover and found only one set of really burnt up clutches. very easy to change. i also had that po730 code. car felt like wouldn't shift into 3rd 4th 5th. better than spending $2000 for a used tranny!!

indicates a TCM problem
run the fault codes to determine the exact problem area

replace the input and output speed sensors
