Condensation drain / various electrical faults

If there are any electrical faults in the above vehicles, these may be caused by a faulty or missing condensation drain.

Another cause may be an air distributor that was damaged during production.

A faulty drain may allow water to reach the BCM (Body Control Module), leading to the following faults:

• Central locking system does not work
• Wipers do not work
• Horn activates itself
• Engine will not start
• Body systems do not work
• Various fault codes

Proceed as follows to rectify the problem:

• Check that the condensation drain is present and whether it is broken
• If necessary, fit/replace the condensation drain
• Check the air distributor housing for damage/traces of water and replace if necessary
• Check the BCM for water ingress and corrosion and replace in the event of water ingress
• Clear the fault memory
• Carry out performance check
