Hi!
When going over small sharp bumps in the road, there is some noises coming from the roof where it locks to the windscreen frame.
Is there a way to adjust/ lubricate it to reduce the noises it makes?
I get a "permission denied" trying to access the link, but the part number (0009893660) is the genuine MBZ lubricant and I highly recommend it. It will cost your around $45 at the dealer, but it's worth it and the tiny little vial will last you for years - probably the life of the car.
try adjusting the bump stops, also lubricate all the rubbers to ensure the roof pulls tight when closing.
Warning: You need to open the roof half way, so be careful when working as it will close after a few mins, you are alerted by a chime. The correct safety measure is to use a tool to support the front edge to the windscreen, or a piece of wood about 1ft long will do.
Tips Use a little lubricant on the rubber stop to allow the plastic tube to slide over easier and carry a 10mm spanner in the car so you can adjust then drive then adjust more if needed. All in it takes less than a minute to adjust.
The upper bump stop has a tube cover for aesthetics as it can been seen in the cabin. the lower one does not as it is hidden. Upper bump stop with tube pushed down, using a flat screwdriver, lubricate the rubber stop first to assist, lower bump stop.
