Dash message saying the engine will not restart in 400 miles, or an AdBlue warning that will not clear? Our mobile technicians attend across Kensington, Chelsea, Knightsbridge, Earl’s Court and Notting Hill, diagnose the fault and repair it where the vehicle is parked. Mobile AdBlue repair starts from £249, with a fixed price agreed before we begin.
We repair AdBlue quality faults, SCR efficiency codes, leaking tanks and lines, failed pumps and dosing modules, heater and wiring faults, and NOx and level sensor problems. Each job includes diagnosis, repair and a proper reset, so the countdown clears and stays cleared.
Large diesel SUVs on short local runs, cars left standing for weeks and builders’ vans working on basement conversions are all common here, and each one puts a different strain on the AdBlue system. HGV, economy and performance remapping is available too.
Tell us about your vehicle — we’ll reply with a fixed price.
Most of our Kensington and Chelsea callouts come from owners whose dash has started a countdown, or a builder whose van has cut power on site. Send your postcode, the make and model and what the dash says, and we will head over. We agree a safe place to work with you before we start.

From a Range Rover on the school run to a builder’s Transit on a Kensington basement job, our mobile technicians cover SW3, SW7, SW10, W8 and W11 with AdBlue repair, diagnosis and resets. We also work on BMW X5, Mercedes GLE, Audi Q7 and Volvo XC90 diesels. Repairs start from £249.
The warning is on and the cause is unclear. We trace it through the fault codes and fix the part behind it, so the message stays off.
Pump, dosing module, tank, lines, heater and sensor repairs carried out at your address, with the part and price agreed first.
A full scan of the AdBlue, SCR and NOx systems on site. You leave with a named fault and a price, not a guess.
After the repair the system is relearned and tested, so the start countdown clears and the car behaves normally again.
Only raised where a repair keeps failing. We go through the MOT and emissions consequences before anything is agreed.
Testing, cleaning and replacement of NOx sensors, based on what the live readings show and not on the warning alone.
For lorries and larger commercial vehicles supplying the borough's shops, hotels and building sites, set up around the loads they carry.
For vans and diesels doing long days in slow London traffic, aimed at reducing fuel use.
Sharper response for diesel SUVs and saloons, done with engine and emissions hardware in mind.
A simple process built to get you back on the road with as little disruption as possible.
Make, model, postcode and the exact message on the dash. A photo of the warning helps.
Our technician reads the AdBlue, SCR and NOx codes at your address before anything is touched.

We cover the whole of Kensington and Chelsea, from Notting Hill and North Kensington in the north to Chelsea and World’s End in the south. Response time depends on your exact location and current demand.
From AdBlue warning lights and start countdowns to quality faults, SCR efficiency codes, dosing problems and sensor failures, our mobile technicians diagnose and repair common AdBlue faults across Kensington and Chelsea. We come to your address and work to get your vehicle running properly again.
The dash counts miles down to zero. At zero many cars will refuse to restart once switched off, so the repair is best done beforehand.
The tank is full but the car reports poor quality fluid. The cause can be diluted or contaminated AdBlue, or a quality sensor that has failed.
The exhaust system is no longer cutting emissions as it should. A worn NOx sensor, a weak pump or a blocked dosing module can all set this code.
White crusty residue near the tank, filler or lines is dried urea. It points to a leak or a seal problem that needs looking at.
Cars left in mews garages for weeks can return with crystallised fluid or sensor errors the first time they are driven again.
Damaged wiring or a corroded connector to the pump, heater or sensor can set a warning even when every part is working.
Heavy diesel SUVs spend much of their time on short hops between home, school and the shops. The engine warms up, then gets switched off before the exhaust has done a full cycle. Over months that wears on the NOx sensors and the dosing module. A dash message on one of these cars is worth reading early, since the parts involved cost more the longer the fault runs.
Basement conversions keep vans on the road all day, loading, idling outside sites and moving a few streets at a time. Dust and idling put load on the same AdBlue parts. Builders lose most when a van drops into limp mode with materials on board, so we book these repairs around the site day where we can.
A car parked for two or three weeks can come back with a warning. Fluid can crystallise in the lines, and a quality reading can drift. Topping up is rarely the fix in that situation, and a scan will show whether it needs a clean, a sensor or a replacement part.
We cover the borough from Notting Hill and North Kensington in the north to Chelsea and World's End in the south, and from Knightsbridge across to Earl's Court.

The car is counting down miles until it will stop allowing a restart. It can happen from low fluid or from a fault in the AdBlue system. Once the count reaches zero, the engine may not start after being switched off. We scan the car at your address, find the cause and repair it before that point where possible.
Usually yes. We need a safe, legal spot to work from. If the street has tight restrictions we will agree the position with you first, and suggest a nearby alternative if needed.
Repairs start from £249. The final price depends on the fault and the vehicle, and parts for premium SUVs can cost more than parts for a standard van. You get a fixed price once the fault is found and before any work begins.
Fluid left standing can crystallise in the lines or pump, and its quality reading can drift. That can set a warning the first time the car is driven again. A scan shows whether it needs a clean, a sensor or a part.
Yes, if the level really is low. Use proper AdBlue and never add water or another fluid, and don't overfill. If the warning stays after a top up, the fault is elsewhere in the system and needs a scan.
The quality sensor is reading the wrong concentration. That can come from diluted or contaminated fluid, or from a sensor that has failed. We check the sensor readings first, then tell you whether the tank needs draining or a part needs replacing.
Yes. We attend vans and light trucks at building sites across the borough. Give us the site postcode and the working hours, and we will book a slot that fits around the job.
We can offer a slot within a window you give us, and we come to wherever the car is parked. Tell us the earliest and latest times when you book, and we will confirm what we can do.
It often does. The residue is dried urea from fluid that has escaped, usually at a filler, line, seal or the tank itself. It needs inspecting, since the leak will not stop by itself and the level will keep dropping.
It depends on the fault. We diagnose first, so we can give you a realistic time once we know the cause. A sensor swap is quicker than a pump or tank replacement.
From £249. We scan, quote and repair at your address, from Chelsea to Notting Hill.
