S3 Fault Code Woes...

A few weeks ago i hit a speed bump....the speed bump shoved my exhaust up, smashing my lambda sensor off the heat shield. It was broken and obviously my engine management light came on.

I went to my local motor factors and bought a universal, wire it up yourself, lambda and installed it. i cleared the fault codes and 1 hour later, the engine light was on again.

I put this down to the lambda i bought not being compatible so i bought a specific NGK Audi S3 lambda and installed it. cleared all codes and sure enough, 1 hour later, engine management light.

The thing is, im getting an array of codes now!!! Could damaging the lambda have done something more serious? shorted something? it snapped at the nut.

Heres my codes now

All those things run from the same +12v feed.

If you check for voltage between the blue/yellow wire from any of those components and earth you'll probably find there isn't any, there should be lol.

It'll have blown a fuse in the fusebox on the side of the dashboard, can't tell you which one it is of the top of my head, but it's one of the many listed as 'engine management' on the index card.

Thanks for the help.... Although any tips on which fuse to try?

i love you

yes indeed. thanks very much.
