Re: How to change ECU chip A4 1.8T?
The chip is soldered onto the PCB in the ECU, and can't be updated through
the diag port. Tuners either remove it and resolder their chip on, or put a
socket in and then give you the ability to swap them. Most tuners have a
loaner program where you can give them a deposit and get a 'new' ECU then
send yours back to them as soon as you make the swap. Tuners include: MTM,
Wetterauer, TAP, and then a host of smaller operations. I had a Wett chip in
my A4, was great - have more info and web links etc. if you are interested.
