- 1991 SL 500 (R129) and 2008 C220 CDI (W204)
Hi,
I've been looking for a good (but not too expensive!) R129 500 SL for some time now and I recently purchased a 1991 500SL in astral silver with navy interior. This is my first SL and I'm really pleased with it - it's got full service history and only done 57k miles.
It has however just developed an idling problem - it is over 1000rpm in drive and when I shift to N or P it surges to around 2500rpm. It is so bad that it has really become undriveable (when I shift from P to D because of the revving I get wheelspin!). The gearchanges have become snatchy and I don't want to damage the transmission.
I've Google'd the problem and it seems the issue could be with the Idle Control Valve? Have any of you experienced similar issues & from where could I obtain this part at what sort of price?
Any help would be gratefully received as it is stopping me enjoying my new toy!
