Check engine lights
Fault codes are the start of diagnosis. Lorenzen Motors traces the cause through data, tests, and model-specific repair information.
Diagnostics
Find the cause before replacing parts.
Mercedes warning lights and electrical faults need a measured diagnostic path that starts with symptoms, data, and testing.
Electrical faults
The shop uses a Fluke 199C scope meter and Fluke 289 multimeter to help locate electrical malfunctions.
Internal inspection
A HawkEye borescope can inspect internal combustion areas before expensive disassembly is considered.
