Got an AdBlue warning, a countdown to no start or limp mode on your car or van? We offer mobile AdBlue repair across the UK from £249. Our engineers come to your home, workplace or roadside, scan the system, find the fault and fix it on the spot, so you do not need a tow to a dealer.
Most AdBlue faults come down to a failed pump, a blocked injector, a faulty NOx sensor, a dead tank heater or a level sensor that reads wrong. We repair the part at fault, clear the SCR codes, code the system and reset the countdown, so the warning does not return a few miles later.
We repair BMW, Mercedes-Benz, Audi, Volkswagen, Ford, Land Rover, Volvo and Nissan, along with Peugeot and Citroën, and vans like the Transit Custom and Vauxhall Combo. Choose your make below to see the faults we fix on it, the models we cover and the warning codes to look out for.
Drag to see what each warning stage means.
Every make has its own AdBlue system, warning messages and weak points. Pick your vehicle to see the models we repair, the faults we fix and the codes behind the warning. Every repair is done at your location, from £249.

Our engineers repair AdBlue faults on every make above at your home, workplace or roadside. Search for your town or pick your region to open the local page for your area.
No area matches that search. We come to you across the UK, so call 0330 043 4431 and tell us where the vehicle is.
Can't see your area? Our engineers travel across the UK. See all locations or contact us with your postcode.
We repair BMW, Mercedes-Benz, Audi, Volkswagen, Ford, Land Rover, Peugeot, Citroën, Jaguar and Vauxhall, including vans such as the Ford Transit Custom, Vauxhall Combo and Vauxhall Vivaro. If your make is not listed, call us with the warning and we will tell you if we can help.
AdBlue repair starts from £249 on every make we cover, and diagnosis starts from £199. The final price depends on the part at fault, such as a sensor, pump, heater or injector. We tell you the cost before we book the visit.
Yes. Our engineers come to your home, workplace or roadside across the UK, so you do not need to tow the vehicle to a dealer.
P20EE means the SCR system is not cleaning the exhaust well enough. On a BMW, a dosing fault or a NOx sensor fault can set it, so we check those first before blaming the catalyst.
It is the AdBlue countdown. The car is counting the miles left before it refuses to restart. Once it reaches zero and the engine is switched off, it may not start again. We repair the cause, such as a weak pump, a failed heater or a NOx sensor, then reset the countdown.
You can drive until the countdown ends, but do not switch the engine off with only a few miles left. At zero the Audi may refuse to restart. Book the repair while miles remain. We can fix the supply module, the sensors or the injector at your location.
A warning that appears on a cold engine and then fades often points to a tank temperature sensor or a heating fault. AdBlue freezes at about minus 11 degrees Celsius, so a weak heater shows up first in cold weather. We test the sensor and the heater and repair the one at fault.
Yes. We repair the Transit, Transit Custom, Transit Connect and Ranger, and cars such as the Focus and Kuga. We service weak or blocked dosing modules, repair heater and tank module faults and check for exhaust leaks that upset the NOx sensors, then relearn the system and test drive the vehicle.
Land Rover calls AdBlue exhaust fluid, so exhaust fluid level low and exhaust fluid system fault are AdBlue warnings. We repair corroded connectors, tank heater and sender faults, blocked lines and injectors, and quality sensors that read wrongly.
That message is the AdBlue countdown, and the car may refuse to start after the set distance. Get it diagnosed before the miles run out. We repair tank heaters, pressure sensors, injectors and damaged plugs or wiring at your location.
A level sender that reads wrongly can make the range drop when the tank is not empty. We replace the level sender, repair leaking or cracked fittings, clean injector deposits and update the software where needed, then relearn the system.
Usually not. A warning that clears and returns often points to a power or earth fault, a tank module fault or a blocked dosing valve. We trace the fuses, relays and wiring, repair the tank module or dosing valve, then relearn the system and road test the car.
It is the AdBlue countdown, warning that the van may not restart after a set distance. On a Vauxhall, pump and heater faults can stop the BlueInjection module working. We repair or replace the module, replace level or quality senders that read wrongly, then relearn the system.
Yes. We do dealer level coding on every job, so the SCR system relearns and the fault does not return.
Often yes. If the countdown has ended and the vehicle will not start, we can still repair it, but it may need a workshop visit.
