What the hazard is
Cabin smoke or a vehicle fire could increase the risk of injury or death to vehicle occupants, other road users and bystanders, and/or damage to property.
What to do
Owners of affected vehicles will be contacted by BMW requesting they immediately schedule an appointment with their preferred authorised BMW dealer to have the rectification carried out, free of charge. Note: Owners/operators should NOT use the following remote functions until the repair has been completed: Climate control, departure plan, pre-cooling, pre-heating, Remote Engine Start (if available in the market).
Defect
The air conditioning (A/C) wiring harness may become damaged during routine microfilter (cabin air filter) replacement. This may cause an internal short circuit, which could lead the sensor to overheat. This could pose a risk of smoke entering the cabin or a vehicle fire while driving.
