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.

The new ISTA Version is also able to be used in case of a Remote Software Upgrade (RSU) programming failure to get the customer car reprogrammed on site. In case of a Remote Software Upgrade failure, the engine start is prevented for safety reasons until the vehicle is programmed correctly. Most of the errors occur when only one control unit fails to program correctly.
