Vehicle Weaknesses

WeaknessCost
!Convertible roof doesn't close fully

The E64 convertible roof sporadically won't close fully — it stops about 30 cm before the windscreen. Cause is a faulty rotation angle sensor on the main post, left side. Cheaper to repair than the roof itself.

Symptoms: Roof won't close to windscreen, stops halfway, roof fault message, manual assistance needed to close.

!Water ingress in hood compartment and boot

Water enters the boot through blocked drain channels and faulty vent flaps under the rear bumper. In 95% of cases the left/right vent flaps under the bumper are the cause. Wet carpets and damage to electronics under the boot floor result.

Symptoms: Damp boot, wet carpets, water smell in cabin, standing water in spare wheel well
