Mercedes-Benz Specialist


Cornerstone Garage in Tiverton opened in July 2010 with the appointment of Mercedes Benz Master Technician Stephen (Jed) Chamberlain. Stephen brings a wealth of knowledge regarding Mercedes Benz vehicles and their complex electronics.

Cornerstone Tiverton, like Ilton, have a fully licensed Star Diagnostic machine to ensure work procedures are carried out exactly as required whether it be Service Assyst Plus or a fault diagnosis. Star also allows us to code new keys and control units, update current control units and code new equipment to the vehicle. Services previously only available at a dealership.

Cornerstone Garage can offer you up to a 50% saving on dealership labour rates.

All parts are genuine Mercedes Benz delivered to us daily from Mercedes.

Star Diagnosis:

 This diagnostic system comes straight from Mercedes Benz and is an essential tool for the workshop.

With the increasing complex control systems this equipment allows us to test, check and diagnose faults as quickly as possible. It also enables us to code new control units and keys.

A software update comes from Mercedes Benz in Stuttgart every month to ensure we are fully up to date with all the required information.
