Hi all firstly iv got a b7 rs4 the car started misfiring and then it started to clear the misfiring I turned the engine off and then try to start it but won't start iv checked to see if there any power to the coil. Packs and there no power coming to the packs so any thoughts on this problem and second thing does any one know were the rpm (g28) sensor is located Iv looked everywhere and can't find it any pics of location will be great

Thanxs

Does the engine turn over?
Most cars I've had previously (but don't know with the RS4) will cut out the starting mechanism if the crankspeed sensor is playing up to protect the engine.

I know it's the obvious thing, but have you checked the fuses and relays?

Do you have an engine failure lamp on the dash? (either the MIL or EPC lights)?

Yes the engine does turn Over but no spark does anyone know if it could be the fuse or relay but which one engine light on but stated misfire on a few cylinders so did change all coil packs and plugs

I'm struggling with that response... really hard to understand (and not tims ).
Do you have an engine light on on the instrument cluster? if so then get the codes scanned using VCDS/Vagcom or even a cheap ODB reader.

Engine light was on now reset no fault code
