🚨 AdBlue problems? Don’t ignore them! 🚨
This Mercedes C250 BlueTEC came into us with an issue within the AdBlue dosing system.
AdBlue is an important part of the vehicle’s emissions system. It is injected into the exhaust system to help reduce NOx emissions. But when the system develops a fault, AdBlue can crystallise around the dosing valve and restrict or affect the correct delivery of the fluid.
As you can see from the pictures, there was significant AdBlue crystallisation around the dosing valve.
We carried out a proper diagnostic test using our Bosch diagnostic equipment, measured the dosing quantity and checked it against the manufacturer’s specified values.
🔧 Diagnose it properly. Fix it properly. 🔧
At Fine Drive Auto Centres, we don’t just clear the warning light — we find the cause.
