Initial publication

The rear spoiler extends slowly or operates erratically. An error light for the rear spoiler may be illuminated.

Technical Background
The rear spoiler operation can be restricted due to corrosion in the spoiler drive unit. As a result, the rear spoiler
becomes stiff and does not reach its end points. This may cause a rear spoiler error light to be illuminated.

Production Solution
The drive hinges are now pre-oiled at the supplier. The material of the hinge bushings has also been improved.

2. If corrosion in the drive unit hinge is found to be the cause of the function restriction, the
hinges can be lubricated using special lubricant G 052172A1 (Figure 2).
Move the spoiler mechanism outward to expose the hinges and apply the special
lubricant. Run the spoiler in and out several times to distribute the lubricant thoroughly into
all of the hinge components.
