Frequently Asked Questions

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

• Confirm there are no other warning lights (oil, temperature, ABS) on the dash that indicate a more urgent condition.
• Check the fuel cap for proper seating and tightness—an unsecured cap is a common, low-cost cause.
• Note any changes in performance, smells, or exhaust smoke and avoid heavy towing or loads until inspected.
• For warranty protection, schedule a diagnostic with our certified technicians—repairs covered under warranty must be performed at a certified dealership.

What is the most common reason for check engine light on a 2018 Mercedes-Benz Sprinter 2500?

• Common causes include emissions-related components such as DPF/DEF system faults, oxygen sensors, or EGR/DPF regeneration problems—especially on turbo-diesel engines.
• Sensor failures (mass airflow, boost pressure) and issues related to the turbocharger or fuel system can also trigger codes.
• Minor causes like a loose fuel cap or poor fuel quality may be quick fixes, but diesel-specific systems often require specialized diagnostics.
• Our technicians diagnose with manufacturer tools to identify exact causes and help minimize both immediate repair costs and long-term downtime.

How long does a check engine light service take?

• Basic diagnostics to read and interpret fault codes typically take about 30–60 minutes.
• Simple repairs (tightening a fuel cap, replacing a sensor) can often be completed the same day; more involved repairs like DPF regeneration, turbo work, or fuel system service may require several hours to a day or more.
• We prioritize accurate diagnosis to avoid unnecessary parts replacement—this saves money and time compared with repeated visits to independent shops.
