My car metal roof is making noises like asif it is stuck somewhere and its not closing properly ? any ideas
When the roof is closing and it stops does it make a juddering noise or is it quiet. First of all open the roof fully and check that the guide rails on either side are free of dirt, use a paint brush and WD40 and use plenty of cloths to prevent dirt splashing every where. I have a '96 E-class but I think the roof mechanism is very similar.
If the roof make a juddering noise this is not so good. The motor is located above the left rear wheel in the boot. The mechanism consists of a toothed cable driven by the motor through a pipe guide to the rear of the roof panel. You will have to disassemble this motor and gain access to its drive gear in order to clean it of metal shavings/debris and to re-grease it. It is a very frustrating job and one that may wish to leave to the Mercedes experts because even having rebuilt the motor there is a real knack to adjusting it.
If the roof is just coming to a stop and not making any noise then you in luck. Locate the motor and the large central nut on top is the clutch adjuster. Tighten it by 1/6th of turn and try to close the roof again. Keep adjusting the clutch tighter until the roof closes. If you hear juddering noises, immediately slacken the nut off and the above notes will apply.
