CLIMATRONIC Control Module A/C Control Head: Removing
-- Check coding and adaptation of A/C control head Climatronic Control Module -J255- via the Replace Control Module function of Guided Fault Finding (in the event that A/C control head Climatronic Control Module -J255- is to be replaced).
-- Switch off ignition.
The removal of the Climatronic Control Module -J255- A/C control head is identical for both Comfort and Basic versions.
The Climatronic Control Module -J255- A/C control head -A- is secured in the center console by four retaining clips -E-.
As of the beginning of 2006, Climatronic Control Module -J255- are installed with gradual introduction of modified clips -A- on the top (clips on bottom remain the same, version -B-), at the same time instrument panel center sections with modified mounting bracket for the top clips version -C- are also introduced. For Climatronic Control Module -J255- units on which clip -B- is installed (force-fitted clip with an angle of approximately 120° installed, on the version that was installed up to beginning of 2006, panel colored pearl-gray metallic), this control and display unit can be removed without removing the center instrument panel vent.
For Climatronic Control Module -J255- units on which clip -C- is installed (form-fitted clip with an angle of approximately 65° installed, on the version that was installed as of beginning of 2006, panel colored black), this control and display unit can only be removed with the center instrument panel vent removed. Refer to CLIMATRONIC CONTROL MODULE A/C CONTROL HEAD . So that clips -C- can be disengaged, one slot -D- each in the instrument panel center section has been installed in the area of the upper mounting bracket for clips.
- With the introduction of form fitting clips -C- (with an angle of approximately 65°) on top of the A/C control head, modified instrument panel center sections have also been introduced (can be detected by a vertical slot -D- in area of top mounting bracket.) If an A/C control head with clips -C- should be installed in an instrument panel center section without this slot -D-, possibly it can only be removed after removing the instrument panel center section (form-fit connection can only be disengaged via this slot from the front).
Climatronic Control Module -J255- units which were installed at the beginning of 2006 with a panel colored pearl-gray metallic, force-fitted clips -B- are installed on the top, deviating from this however during the transition period, form fitting clips -C- may also be installed at some components, only form fitting clips -C- are installed with the introduction of A/C control head units with a panel colored black.
