[s-cars] New sensor still got codes

[iain.atkinson at tesco.net]

i have replaced what i thought was a failing engine speed sensor (G28) on my S6 but it's still throwing me the code, intermittant signal, car is even now starting to cut out on me, not at speed but slow stuff like pulling in the drive or coming up to a junction, any further ideas on why this should be??

I know this one runs off the flywheel teeth, am pretty sure i don't have a damaged flywheel (like missing teeth)as the car starts fine, had a recent clutch done but the car has always thrown this code ever since i first got it 5 months ago. Bentley doesn't seem to show any sort of gap adjustment on this like abs sensors for instance.

Thanks
