Fit the two mounts -2- to the rear spoiler -1- by hand by screwing them in by at least 3 turns.







2. Secure rear spoiler at the left and right hydraulic cylinders.
2.1. Socket-wrench insert P 9752 -4- must be inserted into the bores on the outer pipe -3- and on the mount -2-, and the mount -2- on both hydraulic cylinders must then be screwed into the rear spoiler -1- completely and tightened. Tightening torque: 30 Nm (22 ftlb.)+5 Nm (+3.5 ftlb.)







2.2. Turn outer pipe -3- using the socket-wrench insert P 9752 -4- until the bore on the mount -2- is directly covered by the outer pipe -3-. The bore on the outer pipe -3- must point towards the rear in the direction of travel.

Subsequent work

Checking rear spoiler

INFORMATION:
- The rear spoiler reduces the drag and, particularly at higher speeds, reduces the rear-axle lift.
- The rear spoiler extends at approx. 120 km/h (75 mph) and retracts again at approx. 80 km/h (50 mph).

1. Extend rear spoiler.
1.1. Switch on the ignition and press the button until the rear spoiler reaches its upper limit position.
1.2. Switch off ignition.

2. Check extension height of rear spoiler.







2.1. Check extension height in the centre between the lower edge of the rear spoiler -1- and the upper edge of the rear lid -2-.

Extension height on Coupe: -X= 35 mm-
Extension height on Cabriolet: -Y= 60 mm-

3. Retract rear spoiler.
3.1. Switch on the ignition and press the button until the rear spoiler reaches its lower limit position.
3.2. Switch off ignition.
