We have a 2004 S4 Cabriolet and when we first got it we noticed a 'grindy' on and off noise when starting the car if you held the key fully locked for a second or so before releasing the key.
Normally of course you don't hold the key fully locked, as you release it as soon as the motor starts.
However, this 'grindy' noise could be heard for a split second before you release the key - and sounded AWEFUL!!!
So, logic said starter motor (???). So we removed it, had it reconditioned with a 12 month warranty, and put it back in.
But the noise is still there!!!
Is there something apart from the starter motor this could be - or is it possible they screwed the recondition job?
Has anyone else had this similar issue?
The noise is ONLY when the engine starts and key is fully locked. As soon as you release the key the noise stops.
It's a 2004 manual.
