HELP 300SL Another Roof Problem
 
Hi i have reacently bought a 300SL 24v 1990 G reg, when i got the car the roof was in good working order. Now the roof isn't working at all. one night i decided to put the hard top on. I placed on the hard top and it wouldnt go down in one corner, the red roof operation switch was flashing a pinging everytime we drove the car. We decided to leave the car parked up and have another look the morning after, we then had the roof up down on and off for several times not realising that your not meant to operate the roof more than ten times we then heard a loud grinding sound and stopped everything. we later realised that one of the switches had fallen of on the rear right roof clip. We then manually put the hard top on and it has been into Mercedes Dealership garages several times but all they seem to want to do is change every component of the roof system equaling to the value of £3000. I have tried the code Diagnostic check (thanks to bobterry99) and the codes that i got out of it were 6, 10, 11, 20, and 25. all of the codes have erased excepted from 20 which wont clear and the roof is still not working. the red switch is still pingings and lit up.

Any help at all would be gratefully appreciated

Seems to me that code 20 is for the hard top being in place and is similar to a code 1 in other controllers (no fault found).

I would guess you have a switch that isn't confirming the hard top being engaged.

Hi stevebfl thanks for your reply, from reading other posts I beleive these switches can be adjusted,(not sure how ) will make this starting point,hopefully this would cure the roof alarm and will be able to use my car,
