This Service Information bulletin supersedes SI M51 07 08 dated May 2008.

[NEW] designates changes to this revision

SUBJECT
Tailgate will not Latch Closed

MODEL
R56 (Cooper and Cooper S) produced up to 4/2008

SITUATION
The tailgate latch will not latch in the closed position and the latch appears to be inoperative.

CAUSE
During assembly, the emergency release lever may have been pulled too hard. As a result, the black plastic ball which secures the cable to the latch may have broken off and become lodged in the latch.

CORRECTION
A process improvement has taken place to prevent this situation.

PROCEDURE

1. Remove the rear latch cover trim per repair instruction RA 51 46 050.

2. [NEW] Early production cars have a manual release tether located under the rear seat bottom cushion, which has been eliminated from later production cars.

A. If the car does not have the manual release Bowden cable, operate the manual release lever of the latch, and then remove any debris which may be lodged in the latch.

B. If the car does have the manual release Bowden cable, determine whether it is still connected to the release lever on the latch. If the cable is NOT connected to the latch, the retaining lug is likely lodged in the latch. Continue with the following procedure.

3. Remove the lodged black plastic ball from the area around the release lever (1).

4. [NEW] Replace the emergency release Bowden cable per repair instruction RA 51 24 065.

NOTE:
If the vehicle was not equipped with a release cable from production, it should not be retrofitted to that car.

5. Ensure proper operation and reassemble the vehicle.

Hi,

I hope you are doing well. As far as the issue, for it to unlatch at random times, there must me some shorting to power. Take your test light and see if you start moving wiring around if you get hits of power.

Let me know.
Joe

You mean hits of power to any of the wires just by moving them? Isn't some of them supposed to have some power already even when the latch is open or closed?

I looked through the schematic, and to the best of my knowledge, power should only be sent to the latch when requested.

Something is shorted to power. Chances are the switch is bad.

Let me know if you need anything.
