Hi All, just purchased a 2000 pre-facelift 230k and the headlamp switch has a minor intermittent fault. Does anyone know whether this switch is fitted to any other mercedes car? Also, any link to a service manual would be grateful (Haynes don't appear to list one). Thanks, Robert

Pm me your vin (or post it here) and I'll look up the part number for you. You can then most likely find a replacement on eBay or similar...
Will only get to it in about 6 hours though, if no one else responds first...

Mine failed. Progressively. At 110,000km.on a '98 SLK230.
Instrument lights would not come on.
Bought new replacement, was not cheap.
Fixed problem.
I am pretty sure it was a '170....' part number which seems to indicate it is not shared with other models.
I pulled the old one apart. It has a folding flexible wrap around printed circuit board.
During assembly it wraps around the core and
Is progressively soldered to each side, and various plastic bits snap on.
Very interesting design idea, and absolutely not serviceable.
The core has all the contacts that engage as the switch is turned, and pulled(for foglights).
I never did find any evidence of the faulty contact.
Makes a rubic cube look just too easy.

Just buy the new replacement part and fit.
A second hand part might be years or just weeks from going bad.
Set my limit of $100 for a used part, if reasonable mileage.,$50 for high mileage, but never found one.
Replacement ( see Pelican Parts) can be done out the side, but is easier if you remove
some of the lower trim screws to give some more room.
Now replaced , should last another 20 years.,,,,,,for whoever buys my '230.

Switch p/n

Hi
Part number for the headlight switch module is A1705450504
Yes, that is the same part number that I bought, for a '98, 230K , RHD.

Fitment took less than an hour, maybe 30 minutes taking it really gently so as not to break any more screw
fittings.

Thanks again. I am now on the lookout for one at a reasonable price.

Thanks Bryn, been looking most places and yesterday managed to get one from a breakers yards for £35+vat. It's not arrived yet, so can't report on its function. Will update when I've fitted it.
