Hi guys. I hope someone can give me some advice.
I have the above mentioned car. Its a 2007 model. I bought it as a non runner. The car didnt want to start because it had a electrical issue. The previous owner told me that the module for central convenience was soaked in water(under the carpet of the passengers foot well). So i had it replaced and tried to start the car but the immobilizer blocked the car from being started. Then i had the immobilizer bypassed on the ECU as the immobilizer is also built in the cluster which prevented the car to start. Now the car start and drive but doesnt change gears. Its as if it goes into limp mode. Changing gears manually then the car moves good. What i also noticed is that the speedo, rev counter and temp gauge doesnt work.
So i did a scan again and it keep telling me that the "powertrain data bus is defective"
So what i did was i got hold of a lock set(ecu,cluster, ignition,key and door lock) from a scrapyard.
So i had it installed hoping that it will eliminate the powertrain data bus defective problem.
I did a scan after the install and the same problem shows up again "powertrain data bus defective"

So my conclusions is: either there is a module not communicating with the ecu or cluster or there is a wiring problem somewhere.

Any suggestions or advice appreciated.
Thanks in advance

Perhaps posting this in the A4 Forum would net you a response. Q5/7 guys don't seem as prone to tweaking with their computers...
