MODEL
E93
Produced to July 2012
SITUATION
2010 BMW 335Cic Convertible (E93) L6-3.0L Turbo (N54) 515
The RHT frame is bent or twisted and cannot be operated in either direction, or the roof shells are not stacking properly.
CAUSE
The hydraulic roof cylinders operate out of sequence causing the frame to twist.
PROCEDURE
1. Replace the complete roof module assembly.
Note:
The new replacement roof module will have a new hall sensor installed to the top frame. This hall sensor will require a wiring harness
modification to the body side harness in order for the hall sensor to function properly.
2. Refer to ISTA Repair Instruction 54 37 900 "Additional work for hall effect sensor in roof package" and modify the wiring harness accordingly.
3. Use ISTA/P to code the vehicle with "Conversion CTM - new sensor roof package stowed, left"
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the latest software.
For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service / Workshop Technology / Vehicle
