B7 RS4 Engine Management Light On

Post by D8MEY » Wed Oct 10, 2018 6:34 pm

Hi guys

My new RS4 avant has the engine light on but no loss of power etc. Have attached a photo.
The car had been to Audi Portsmouth and they confirmed that there was no issues but couldn’t get the light off.

Any ideas what it could be? Thanks

Right done some more digging.... the car had two lamber sensors replaced at a non Audi specialist, and the engine management light couldn’t be taken off using the kit they have.
It went to Audi Southampton to fix the DRC.

Fingers crossed

Audi Portsmouth should have been able to clear the fault then. Unless the fault is still on.
When they plug it in they should be able to do a scan for any faults. Then try a reset. If it doesn't reset the fault is still on.

Hi Mike

There lies the issue.... the car went to Audi Southampton for a suspension issue & the other garage were due to sort the management light as this down to change of the lamba sensors.... the owner needed it back in a rush so h nice why the light is still on... hopefully

I’d strongly recommend buying yourself a genuine VCDS cable - that way you can read and clear codes yourself. It’ll soon pay for itself in saved diagnostics.
