FACTORY BULLETINS

摘要

Automatic headlights that switch on or off "without reason" may be caused by problems with the rain sensor, which also operates the automatic headlights. The lights will work properly using the switch manually. An adhesive pad is used to attach the sensor to the windshield behind the inside rear view mirror. The problem may occur if that area of the windshield is dirty or damaged, if the windshield has been replaced and the wrong sensor was installed or the sensor was installed improperly, or if the wiring in the roof is damaged. The sensor can be tested and new sensors must be "coded" using the factory scan tool. MIL illumination with P0087 indicates low fuel rail pressure. This may be accompanied by P2293 (fuel pressure regulator) and/or P1093 (fuel trim malfunction). The problem may be caused by excessive wear on the cam lobe that drives the high-pressure fuel pump, which will cause excessive wear on the pump's cam follower. The lobe is on the intake camshaft. A new camshaft (06F 109 101 B) has been released with a special hardened finish on the cam lobe. The bulletin states it may be a good idea to replace the cam follower at the same time. The bulletin includes photos showing normal and excessive wear patterns, but no repair instructions.
