Known Problems

Front thrust arm and control arm bushings can crack and sometimes tear completely. If this is not repaired quickly, damage to the front subframe unit will occur, which is very expensive to repair. Updated control arms (that prevent damage to the subframe when the bushings wear out) are available.

Leaks in the pneumatic system will cause problems with the dynamic seats and the trunk and/or door closing assist.

As vehicles age, various problems may develop with the hard and soft tops. If problems are encountered, it would be recommended to have a technician familiar with these tops perform the diagnoses.

On higher mileage vehicles, wear causes noise at the vario roof seals. Lubricating the seals can usually cure the problem; in most cases, the seals do not need replacement.

This vehicle has sensotronic brake control (SBC). If the SBC light on the dash illuminates, have the brakes checked. If the SBC is not working, limited brake pressure is delivered to the front brakes, increasing the distance it takes to stop. The SBC hydraulic unit has a specific service life programmed into the control module. Follow the manufacturer's recommended service procedure for proper maintenance of the SBC.

Internal leaks can cause problems with the load leveling suspension in the rear; the vehicle may ride harshly (no give in the suspension, like you are riding on a brick).
