In the workshop this morning we have a B7 Audi A4 2005 with symptoms all relating to convenience system.
No windows function, no remote central locking.
Upon initial serial investigation we had no communication with central convenience module.
We then quickly removed the floor mats to discover a wet carpet both in the front and rear passenger foot wells.

Water in foot well from Pollen filter housing
Not at all unusual found on these models but annoyingly avoidable with good servicing and maintenance to ensure all water drains are properly cleaned to avoid.
When we removed the passenger seat and carpet trim we discovered the extent of the damage which was very severe having completely submerging the control module and wiring loom leading to significant wring damge and complete failure of the module.

Badly water damaged convenience system module
As you can clearly see the damage the water has caused to the main circuit board which is beyond repair but we shall attempt to repair the sockets in situ to avoid replacing the entire wiring loom inside the vehicle.[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
