If a customer complains about the above problem, this could be caused by a frayed cable harness. Additionally there may be electrical failures/malfunctions. The cable harness runs from the fuse box in the engine compartment (front left) through a passage opening in the wheel arch to the headlamps. Since the cable is not protected at this opening, it may become frayed here due to vibration. This then leads to the above-mentioned problems. In this case, the damaged areas on the cable must be repaired. Then protect the cable harness in the area of the passage hole with a corrugated pipe in order to avoid repeated chafing. Below is a summary of corrugated pipes. For details on installation material, refer to Hella Bulletin with order 9Z2 999 029-115.
