R107, New Parts Kits and Manuals

Many owners forget that sunroofs need to be serviced. If neglected there is a price to pay. The NUMBER ONE cause of sunroof failure is lack of lubrication! When a sunroof can not slide easily on the tracks due to dried out lubricant and dirty slides, it puts a heavy strain on the drive mechanism. This leads to tilt arm, motor drive and cable failures. Even manually operated sunroofs can suffer from broken handles and latch mechanisms due to lack of proper lubrication.
