i've had a search but can't find what i thought i'd seen before.cheers,phil.

What is the engine code Phil?

[philS2]

good question.hold on i'll make a call.it's the 8 valve by the way.

[Nuvo]

It's likely to be either ABK or ACE I think.

[philS2]

he's just said it's the aad mate.

[Nuvo]

AAD is an earlier block. What year and model of car is this? Audi 80 series 3 or 4 (90-92 and 95 onwards)? Also availble in Audi 100s (91-92) I think. Oh and not forgetting Coupes (90-91).

[philS2]

yeah it's in a 91 coupe.

[Nuvo]

I'll have a dig for you when I get a chance.

[philS2]

thanks mate.

[Nuvo]

This AAD engine uses the KE Motronic system, so this should help:
