Common issues with Mercedes


DPF: The Diesel Particulate Filter removes harmful chemicals from your vehicle’s emissions. So when this is not working correctly, it can cause a failed NCT. Save yourself the stress and let one of our team check the life of your DPF.


Injector Problems: Leaking injectors can cause an extensive build-up of carbon in your engine, which will eventually cause significant damage if left undetected. This is a common problem with Mercedes vans in particular. If you notice a change in performance, we strongly recommend you get this checked by one of our Mercedes technicians.


Adblue warning light: AdBlue is a fluid designed to remove harmful chemicals from your Mercedes’ exhaust emissions, but we have also seen a problem with the software and sensors, which causes the engine not to start. Contact one of our team to check your AdBlue levels.


Wiring: A faulty wire can bring your Mercedes to a halt as it can affect several of the vehicle sensors. A common problem we see is faulty wiring causing your DPF sensor to misread and therefore causing a drop in performance.


Water Pumps: Water pumps are vital in making sure coolant is pumped around your Mercedes’ engine. With a faulty pump, you may notice your engine overheating or coolant loss. Running your Mercedes at an increased temperature for a prolonged period will end up in extensive repairs.
