FIND THE CAUSE BEFORE REPLACING THE PART
A check-engine light does not always mean the same thing. It may be caused by a sensor, misfire, air leak, fuel issue, cooling problem, ignition fault or control-unit communication issue.
At OFJ Automotive, Mercedes-Benz engine diagnosis starts with fault-code reading, but it does not stop there. We test the related systems, review live data and confirm the actual cause before recommending repair.

FAQs
What does a check-engine light mean on a Mercedes-Benz?
It means the engine or emissions control system has detected a fault. The cause may be minor or serious, so the vehicle should be diagnosed properly.
Can I drive with a check-engine light?
If the light is flashing or the vehicle is misfiring, overheating or losing power, avoid driving and arrange inspection. A steady light should still be checked as soon as possible.
How does OFJ diagnose engine faults?
OFJ uses XENTRY Diagnosis, live data, visual inspection and supporting tests such as smoke testing, leak checks and electrical testing where required.
Can OFJ diagnose engine misfires?
Yes. OFJ checks ignition, fuel, air intake, compression and related control systems to identify the cause of the misfire.
Do you replace parts immediately after scanning?
No. A scan gives direction, but OFJ tests the affected system before recommending part replacement.
