I have a 2001 A4 and the car will not start intermittenly. Turn the key and nothing, no click sip. If I disconnect the battery and reconnect every thing is fine. I have a new battery and it has done it with the old battery and the new. I'm stumped, I've checked the 5 grounds I can fine and they all look good. I don't know if one of mt battery leads could be going bad. I just don't know. Any ideas would be helpful.
Thanks, Laurence

Try cleaning the resistor on the key?

I had the same issue a couple of years ago. Replaced the starter and all is good.

Thanks I'll try that. I had the starter out for the heads and cam I did so I know how to do that.

Only because you said you disconnect and reconnect the battery and its ok . . .

The battery cables on the C5 sometimes look fine but in fact are loose (not where you tighten them, but in the crimpied connection that attaches the lug). Might take a look there. Move them and see if there is play at the connector when you jiggle the cable.
