An AdBlue pressure sensor fault means the sensor watching pressure inside the dosing system has stopped sending the ECU a reading it trusts. Could be flat. Could be jumping around erratically. Could just be drifting outside what’s normal. It’s not…
An AdBlue injector leaking means fluid’s escaping from the injector, or from the seal where it meets the exhaust, instead of landing in the exhaust stream in the precise dose the system needs. Flip side of a blocked injector, really.…
An AdBlue tank module communication fault means the module sitting inside or on top of the tank, the one handling the level, temperature and quality sensors and often the heater circuit too, has stopped talking to the rest of the…
Most people have never heard of the AdBlue filter. That’s fair enough. It’s tucked away inside the tank or the pump module, nobody sees it, and it doesn’t appear on any service schedule. But when it clogs, it can cause…
You paid for the clean. The garage pulled the injector, chipped the white crust out of the pipework, sprayed everything down, and sent you off with a clear dashboard. Then a few weeks later (sometimes a few days) the light’s…
A new AdBlue pump that leaves the warning light on usually means the pump was never the real fault, or something was missed when it went in. The usual causes are a blocked or crystallised line or injector, a worn…
Battery’s brand new. Everything else on the dash looks normal. And there it is anyway, an AdBlue warning that wasn’t showing before anyone touched the battery at all. Confusing moment for most people, because the AdBlue system and the battery…
Pump’s running. You can hear it. And the system still won’t build pressure, like it’s working for nothing. That particular combination throws people more than almost any other AdBlue symptom we see, because the obvious assumption, that the pump’s dead,…
Warning light’s on. Tank’s full. And somewhere in the fault codes sits a reference to temperature rather than level or pressure, which throws a lot of people, because nobody expects a thermometer to be the thing stopping their van from…
Tank’s full. Warning light’s still on. Vehicle still won’t start properly. That’s the exact moment most people call us, confused and a bit annoyed, because they did the obvious thing and it didn’t work. Running the AdBlue tank properly dry…
