Car Diagnostic Inspection for Mercedes-Benz
A car diagnostic inspection costs RM 80 for a small car and RM 120 for a large one, taking about an hour. The inspection identifies the likely cause of a warning light, poor performance, or an unknown fault before you commit to repairs.
What does a diagnostic inspection include?
The inspection starts with a review of your symptoms. An OBD scan reads any fault codes stored in the engine computer. A visible multi-point inspection checks fluid levels, battery condition, hoses, and connections. You receive a findings report and a quote for any repair needed.
Why does Mercedes-Benz need a diagnostic inspection?
A-Class, C-Class, E-Class, GLA, and GLC models commonly present battery and charging faults, cooling and air-conditioning leaks, and suspension wear. A diagnostic scan pinpoints whether the issue is electrical, fluid-related, or mechanical before work begins.
What symptoms should I mention when I book?
Tell the workshop whether you see a check engine light, battery warning light, or oil pressure warning. Describe any noise, loss of power, or unusual smell. If the car feels wrong but you cannot name it, describe what changed and when it started.
What changes the inspection cost?
The base inspection is RM 80–120 depending on your car size. If specialist testing emerges during the scan—such as compression checks or electrical circuit tracing—those are quoted separately after the initial inspection is complete.
Diagnostic inspection cost and duration by car size
| Car size | Cost | Typical duration |
|---|---|---|
| Small car (A-Class, GLA) | RM 80 | ~1 hour |
| Large car (C-Class, E-Class, GLC) | RM 120 | ~1 hour |
Mercedes-Benz specifics
Mercedes-Benz A-Class, C-Class, E-Class, GLA, and GLC frequently come in with battery and charging faults, cooling leaks, and suspension wear. A diagnostic scan identifies whether the warning light points to an electrical fault, a refrigerant or fluid issue, or worn components, so you know what repair to approve.
Frequently asked questions
Will the diagnostic tell me exactly what is wrong?
The OBD scan reads fault codes that point to the problem—for example, a misfire in cylinder two or a battery voltage fault. A physical inspection confirms whether the cause is a loose connection, a failed component, or wear. Some faults need specialist testing to confirm; that is quoted after the initial inspection.
Should I book a diagnostic before I book a repair?
Yes, if you see a warning light or the car is behaving oddly. A diagnostic is faster and cheaper than guessing. Send the light or symptom on WhatsApp before you set off, and the workshop can confirm whether it needs the full hour or a shorter booking.
How long after the diagnostic do I get a repair quote?
You receive a written findings report and quote immediately after the inspection is done. The quote is an estimate and stands for approval before work begins. If specialist testing emerged during the scan, that is quoted separately once the results are known.
What if the diagnostic finds nothing wrong?
This happens—sometimes a warning light clears itself or a sensor reads falsely. You still receive a report documenting what the scan found and what the physical inspection showed. The workshop advises whether to monitor the car or whether a follow-up inspection is wise.
