Diagnostic Equipment

Railway Street Garage have been, and continue to use, the same professional Mercedes diagnostic equipment as main dealers to diagnose faults and program the cars computers. The Mercedes Star Diagnostics system and Xentry is kept updated to ensure we are able to keep your vehicle at its best. We are able to complete online SCN coding, the same way as a Mercedes Dealership.


Diagnostics has become our key area and with more electrical and computer controlled items being fitted to cars we are seeing an increasing number of faults occurring.

Fault-finding and rectification requires expensive dedicated test equipment and well trained technicians of which we have both. This places us in a strong position to provide "Diagnostic Services" to the general public and trade alike.



We have the experience and capabilities to fault find Mercedes electrical systems to component level. We are able to supply, fit and program new and sometimes used Mercedes electronic control modules and ECU'S. We are able to encode or SCN code new and used control modules using specialist electronic equipment, something that main agents are not able to do.

Common Faults:

Water damaged ECU'S

Corrupted Sam Modules

Suspension Compressor failure

Electronic steering lock failure

Airbag lights

ABS mechanical/electronic faults

Misfire on petrol and diesel engines

NOx sensor failure
