Re: How to change ECU chip A4 1.8T?

[John Cunningham <johnc@together.net>]

Peter -

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.
