Auto Clinics High Wycombe diagnoses and repairs all AdBlue system faults on diesel vehicles. Whether you have an AdBlue warning light, a failed NOx sensor, a faulty pump, or a system that won't accept fluid, our technicians have the equipment to find and fix the fault.
AdBlue is a diesel exhaust fluid (DEF) used in vehicles fitted with Selective Catalytic Reduction (SCR) systems to reduce harmful NOx emissions. It is required in most modern diesel vehicles manufactured after 2016. Running out of AdBlue or having a faulty AdBlue system will trigger warning lights and, if ignored, can cause the vehicle to be limited in speed or refuse to restart after switching off.
AdBlue faults we diagnose and repair include AdBlue warning lights, low AdBlue level warnings, AdBlue quality fault warnings (indicating contaminated or incorrect fluid), NOx sensor failures, AdBlue pump failures, AdBlue tank heater faults, SCR catalyst issues, and AdBlue injector blockages.
We connect our specialist diagnostic equipment to read all AdBlue and SCR system fault codes, identify the root cause of the warning, carry out the necessary repairs or component replacements, and clear the fault codes to confirm the system is operating correctly.
If your AdBlue warning light has come on simply because the fluid is low, we can top up your AdBlue fluid on site using the correct specification fluid for your vehicle.
We work on AdBlue systems across a wide range of diesel vehicles including BMW, Mercedes, Volkswagen, Audi, Ford, Vauxhall, Renault, Peugeot, Land Rover, Volvo, Toyota, and more.
