Mercedes Benz C class for diagnosis of the wipers not working! Extensive checks of the wiring to the motor confirmed the LIN signal was not been supplied by the front SAM control module which on the W204 chassis also acts as the Central gateway!

A 2nd hand unit was supplied by the customer and thanks to our new state of the art diagnostic computer – the Topdon Phoenix Max.

He carried out the latest software update and SCN coded the new module. Vehicle now repaired for a fraction of dealer costs.

The Phoenix Max really helps for following:
Mercedes Benz control module programming;
SCN coding;
Software updates;
electrical testing.
