Relay SIEMENS V23078-C1002-A303 BMW VW Mercedes Audi

Do you have sometimes problems with the electric windows in your BMW, Mercedes, Audi, Citroen, Seat or VW?

In the 99% of cases is there a failure of the power relays on the ECU’s / modules / computers. This problem occurs when the electrical contacts within the relays are burning off through short sparks during the switching operation (take a look to the attached picture). At the beginning you will observe the malfunctions on hot days or if the car is parking in the sun and some time later they will stop their function.

The affected relays from manufacturer Siemens/Tyco with the ID V23078-C1002-A303 xxxxxxx you will find in following cars:

· BMW E46, E83 X3, E52 Z8, E85 Z4, E53 X5, E39, E38 (Grundmodul/ZKE - el. windows)

· Citroen (el.Windows, central locking system)

· Audi A2 A3 A4 (el. windows, locking system)

· VW Golf 4 and Sharan (el. windows)

· Seat Alhambra (el. windows)

· Mercedes 500 sl (el. windows)

There is no need to change the whole electronic control unit – just change the spoiled relay
