I am having the following code on my primary chipped ECU & back up ECU...
18020: Engine Control Module Incorrectly Coded.
I have a 98 Audi A4 1.8T Quattro (AEB) that is Drive By Cable.
I am trying to change a soft code from both a 557N & 557P ECU.
The 557P has a coding of 06001 which is meant for a Manual transmission.
The 557N has a coding of 06251 which is suppose to be the correct one but
now I am not sure. I spoke to SpeedTuning whom chipped my ECU and I was told
that my coding is incorrect for the 557N.
Unfortunately i don't have a good registered Vag-com (YET!) do to low funds at the moment.
Anyone with a registered legit Vag-com able to help me?
I live in Fremont, CA (East bay Area). I will definitely come to you!!
if you like, i will by you a case of beer! (if over 21 of course) = D
