Can you list all your module part numbers, so thats levelling, central electrics, headlights, gateway, just tryng to see where your issue is as for me it has to be a module or wiring errors.
So tell me, does the levelling module let you login with security access or does it not allow this?
Leveling is 4L0907357 with software 4L0910357 dating from 09. It was from an A3 8P cabrio
CE is a K rev. I also have some issues regarding the coding on CE. Ther's something on byte 1 regarding xenon headlighs and other on byte 2 i think regarding xenon-shutter without shutter installed (bi-xenon)... Don't know what's the right one for bi-xenon...
Gateway is an AD version i recently bought, but this error also appeared on the previous gateway...
Headlights both have a ballast 8E0 941 329, only one dif one is H02 (the one i already had) and the one i put on recently is H03.
I noticed that before the right ballast didn't appear on VCDS, intead of the PN some ---- appeared. Now everything is detected.
It let's me do the sec access no problem with 02000. But when i go to coding and try to replace the 0000255 code with the A3 8p 0000020 it says what i posted above...
"Coding rejected"
"Error 78: unknown"
The faults that appear on the 55 only reffer to coding now. Before i had a comunication problem with the right ballast that was defective.
Now the faults are:
01539 - Headlights Not Adjusted
005 - No or Incorrect Basic Setting / Adaptation - MIL ON
01042 - Control Module; Not Coded
000 - - - MIL ON
02658 - Power Output Stage for Left Headlight (J667); Not Coded
000 - - - MIL ON
02659 - Power Output Stage for Right Headlight (J668); Not Coded
000 - - - MIL ON
Don't know why on earth i can't code this biatch
