defects in materials and/or workmanship that causes a false seat occupancy alert to occur has been extended to 10 years / 120,000 miles as determined from the vehicle's original in-service / first delivery date.

This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle discharged battery complaints.

The seat heater and power supply are inoperative. During the vehicle test, the seat module does not respond. The power supply fuse for the seat module isfound to have blown.

The following fault codes are stored during a vehicle test: 80419A - Left high-beam headlight: Short circuit and/or 8041A5 - light outputs: Number of permitted short circuit cycles exceeded

As a result, the 12-volt battery becomes discharged and may cause a no-start condition.

As a result, the 12-volt battery becomes discharged and may cause a no-start condition.

In the instrument cluster, the red air bag warning light lights up permanently. One of the following fault codes is stored in the ACSM (air bag control unit): 930949 - Knee airbag, driver: short circuit to negative terminal 93094F - Knee airbag, front passenger: short circuit to negative terminal 93094C - Knee airbag driver's side: Resistance too great 930952 - Knee airbag, front passenger: Resistance too great.

A rattling noise may also be heard coming from the electrical coolant condenser (EKMV).

The vent outlet temperatures vary by 25 degrees Fahrenheit or more (38 F to 60 F+; 3 to 15+ Celsius) without changing any climate control settings. A difference may be felt in cooling power compared from left to right. In some cases, the air conditioning may have stopped blowing cold air altogether. A rattling noise may also be heard coming from the electrical coolant condenser (EKMV).

Odor from the engine compartment. Smoke formation in the area of the belt drive. Drive belt damaged or prematurely worn. Torn drive belt.

The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomotors.
