the E-Class model series W210
(1995) and W211 (2002).



Diagnostic Approach

Your vehicle’s is fully electronic and requires one or several diagnostic equipment to be connected first in order, to locate the problem; our technicians use a diagnostic approach. First, they test to see whether components and systems are proper and secure, then they isolate the components or system that could not logically be the cause of the problem. Our technicians will have to test-drive the vehicle or use a variety of BOSCH / other testing equipment, such as on-board and handheld diagnostic computers or compression gauges to identify the source of the problem. This computerized equipment provides a systematic performance report of various components to compare against normal rating. First, the faults codes stored in the engine management computer’s memory must be cleared this could be several codes; the technician must then road/dyno test the vehicle either with the BOSCH / other test equipment in the cab of the vehicle or vehicle or reconnect it back in the workshop. This must continue until the actual faulty component is found, and a new part replaced. After the new parts are replaced the BOSCH / other test equipment must be reconnected, and the final road/dyno test must be carried out.

You would need to book your vehicle into our workshops at your convenience in order to carry out the diagnostic tests.
