Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Look for dashboard messages and additional warning lights—these narrow the issue quickly for a 2025 Mercedes-Benz Maybach EQS SUV.
• If the vehicle is driving normally, note any changes in range, charging behavior, or noises; document them for the technician.
• If the vehicle behaves erratically, loses power, or emits odors, stop safely and contact our service team immediately.

How long does a check engine light service take?

• Initial diagnostic typically takes 30–90 minutes, depending on the issue and whether live data or road testing is required.
• Minor fixes like sensor replacements or software updates can often be completed the same day; larger items such as battery or inverter repairs may require additional time.
