Update of Technical Background and Service Information
Condition
The customer complains of a lack of cool air coming from the A/C vents, or intermittent A/C fan function. The 		
workshop finds the following fault present:
=>
=>
Control unit: Air conditioning (BKE)
Fault code: 008300 – Heater/fresh-air blower motor front – electrical fault
Technical Background
The air conditioning control unit (BKE) contains a current-limiting function to prevent damage to the blower motor
upon cold starting the vehicle. Therefore, if the fan settings on the A/C control panel in the center console are
set to a high fan speed at cold start, the current demand for the blower regulator may not be met. The BKE
then misdiagnoses the current regulation as an electrical fault with the blower motor.
Service Information
Please update the A/C system to software version 0760:
1.
Ensure that the PIWIS Tester is updated to version 41.400.020 or newer.
