2000 e200 exhaust problems and more

[shifty]

recently purchased first mercedes. 2000 e200 115000miles auto petrol.

1) when first purchesed the exhaust seemed very noisy on start up and also caused vibrations. the cat was thought to be the problem and was changed on warranty. however problem stills seems to be there. am being told now that cat takes a bit of time to settle thus causing noise.vibration is gone. does this sound right.

2) srs light on dash and air bag light on middle console stays on. garage says that there are no faults being read and that there is a possible trapped wire causing the lights to stay on.

3) finally what are the w and s in the middle console for and which setting should it be on.

Hi,
Welcome to the forum,
1, Could try lose/collapsed baffles in the exhaust boxes, CATs i thought made a tinkling sort of sound when U/S.
2, SRS light is the airbag warning light when this is lit the cars airbag system will not work. I would,nt except the car till this fault is cleared.
3, W setting= Winter (pulls away in 2nd changes gear at lower revs)..
S setting= Summer (Starts in 1st gear changes gear at higher revs).

Hope this has been of some help.

SRS light means that there's a fault somewhere - best to get it checked out properly. Your car will fail an MOT for a start, as well as the safety considerations. The SRS light must also come on briefly and then go out when turning the ignition on. If it stays off then someones bodged it!

Check the exhaust heat shields. The fixings for these are known to corrode (they are aluminium) causing them to rattle, although admittedly normally at the back. Easily fixed with larger washers and some sealant between the heat shiled and the washer (helps to prevent recurrance).
