ADBLUE & SCR SOLUTIONS

Diagnosis and ECU work for SCR-equipped diesels with AdBlue faults: failed pumps and injectors, NOx sensor codes and countdown warnings.

AdBlue systems are expensive to keep alive. Pumps, injectors, NOx sensors and tank heaters fail, the dash starts counting down the miles until the engine will not restart, and a main dealer quote often comes to more than the vehicle is worth. Remap Man will identify which part of the SCR system has actually failed rather than replacing parts on guesswork, and tell you honestly whether it is worth repairing and what the alternatives are for your vehicle.

SCR is emissions equipment fitted from new and a road vehicle is expected to have it present and working. Send your registration and what the vehicle is used for, and you will get a straight answer about where you stand.

Remap Man offers mobile AdBlue and SCR diagnostics from Swadlincote, covering customers within around 20 miles, including Burton upon Trent, Ashby-de-la-Zouch, Coalville, Tamworth, Derby and Lichfield. Send your registration, make, model and postcode to confirm availability and pricing for your vehicle.

Remapping by make: Alfa Romeo, Audi, BMW, Citroen, Fiat, Ford, Hyundai, Isuzu, Jaguar, Jeep, Kia, Land Rover, Mazda, Mercedes, Mini, Mitsubishi, Nissan, Peugeot, Porsche, Renault, SEAT & Cupra, Skoda, Toyota, Vauxhall, Volvo, VW.

AdBlue & SCR Solutions questions answered

What are AdBlue and SCR?

AdBlue is a urea solution that is injected into the exhaust of many modern diesels. The selective catalytic reduction (SCR) system uses it to turn nitrogen oxides into nitrogen and water.

What does the AdBlue countdown warning mean?

The system has detected low fluid or a fault, and the vehicle is counting down the distance until it will not restart. That restart lock is built in by design, so the warning should not be left until the count runs out.

Why has my AdBlue warning not cleared after topping up?

If low fluid was the only problem, the warning normally clears after a top-up and a short drive or restart. If it stays on, the likely culprit is a component: the pump, the injector, a NOx sensor, the level sensor or the tank heater.

Is it worth repairing an AdBlue system?

It depends on which part has failed and on the vehicle. Finding the actual failed component first, rather than replacing parts on guesswork, is what keeps the bill sensible.
