R230 Roof issue

[Swabyk]

Hi,
I have a low mileage 2009 SL300 R230.

Today I tried to take the roof down for the first time since the winter and it doesn’t work. If I try to open the roof with the boot separator open then I get the message on the dash to tell me to close it, so that works ok. But once the boot separator is closed the roof open switch does nothing. There’s no noise from the pump, no error message at all, just silence.

the battery is ok as all other items work, the roll bar works also, just silence from the roof mechanism.

any ideas what this could be?

thanks
Ken

Could be a fuse, check your hand book to find out which one.

My previous 2007 R230 SL350 developed a similar fault in 2014. A visit to MBS revealed a failed Roof Flap Drive Support (I just looked it up!). This a hinge with a narrow track contacting a microswitch of some kind but the microswitch goes 'off track'. There is a modified part available which has wider track.

Your car is 2009 so may already have the modified part. So just a thought but could equally be just a microswitch failure. MB diagnostics is king here.

OK good luck with it.
PS my car is a 2013 model year.

The roof relies on a lot of things to work correctly, e.g. microswitches in lots of places, windows dropping correctly, flaps, PSE pump, I reckon you'll have to connect it to STAR diagnostics to see where the problem is.

Welcome Ken.

STAR diagnostics are essential - go to a good indy not a main dealer!

If you complete your profile with your location we may be able to recommend someone.

Good luck. NJSS
