Door/Window seal lubricant
I had squeaking/clicking noise coming from the top of the door window (and goes away if I lower the window). I took it to the dealer. All they did was to put some lubricant on the seal. It did help to lower the level of noise, though it did not go away completely. At this it's more bearable.
I asked them what lubricant they used. They said it's proprietary MB tube and it's not for sale.
Does anyone know what kind of lubricant it is?
Thanks
