Can you service my Mercedes and keep my warranty?

Yes. Under block exemption rules, an independent garage can service your Mercedes using manufacturer-specification parts and fluids without voiding your warranty. We record all work and can update your digital service record.

My Mercedes AdBlue warning light is on — what should I do?

If AdBlue level is simply low, a refill resolves it. If the warning persists after refilling, there may be a NOx sensor or SCR system fault. We diagnose the system properly to confirm whether it is a fluid level or component issue.

Do you work on Mercedes vans — Sprinter and Vito?

Yes. We service and repair Sprinter and Vito vans regularly at our Oldbury workshop. Common work includes DPF issues, brake service, and timing chain maintenance on diesel engines.
