Vehicle Information

Condition

A/C Inoperative after Control Unit Replacement

The climatronic control unit does not function after replacement.

Technical Background

NOTE:  

The condition as described does not compromise visibility.

Production Solution

New control unit beginning with VIN 1F_8V000337 (CW 22/07).
