Ordered a set of R8 coil packs from Alex on Monday, arrived within a day. Top service as usual.
All sorted this afternoon. I reckon I could have done the job in under a minute if I didn't have an engine cover! Pain in the arse that thing.
Anyway, I got the codes cleared afterwards (cyl 2 misfire), took it for a good spin, and all seems well.
Hope it behaves itself for a while now!
