My 09 Q7 TDI was suffering a random g31 code upon turning the ignition on. The code was a map vs baro correlation code.(Baro in the ECU) limp mode, barely moves itself.
Off to the dealer.
The map sensor(covered under warranty) did not resolve the issue and was swapped back to original.
I was told it could be the ECU and it is most likely covered under warranty.
The tech support told the dealer to run an overlay harness from the g31 to the ecu and re pin.
I asked why wouldn't you check voltage resistance and continuity?...
The dealer was told they needed to run new wires to the sensor before Audi would approve a new ECU.
When reading the MAP and Baro, Key on Engine Off, the MAP read whatever the barometric pressure was in the weather forecast. When reading the baro it would read world record high pressure last seen in Siberia around 1969...
Paid to have the overlay installed to appease Audi USA. Make the hour drive to the dealer turn the key and pull it into their bay, same deal...
Day later, the ecu is not covered, not in the US, and $2800 3 weeks out if we're lucky.
I've been without a car for nearly 2 months.
Why not cover an obsolete ECU to save a car and save some dignity?
No one will pay 3grand for a computer and programming on that old of a car.
VAG will be paying someone to sort through and scrap this ecu in 5 years so why be greedy?
What are my odds of buyback at this point? Ive already submitted the request.
I'm open to thoughts rants raves insight.
I hate to give up on my love of TDI's but the Q7 is looking like the end of my adventure.
