Year of Manufacture *: 2001
Engine Code or Type *: 1400 AUA
( Optional ) Scanner used: VAG COM
WAUZZZ8ZZ1N018989 model code 8Z0014 engine AUA gearbox FDM
We have the above Audi A2 in at the moment it cranks over ok but wont fire.
No communication with engine ECU using VAG com. Connecting to other ECU’s ok.
Other ECU’s report connection problem with engine ECU.
Malfunction indicator light not coming on with ignition so am assuming it’s a voltage supply problem IE relay fuse etc.
I have checked all the fuses in the main fuse box and all ok.
With the fuel pump relay pulled out the fuel pump can be operated with a power brobe. And when refitting the relay the pump runs for a few seconds as normal.
Injectors are not switching.
Good voltage at coil.
Has anyone got any pin out data for ECU or are there any common problems that may cause this fault.
Hope you can help.
Best wishes
Peter Cooper
