Makes We Cover
AdBlue Specialists for Your Make of Vehicle
We work on diesel vehicles from just about every manufacturer, and we do it every day of the week. Vans, cars and light commercials arrive with the same story: an AdBlue warning on the dash, a countdown to a vehicle that will not restart, and a dealer quote running well into four figures for parts that may not even cure the fault. Our answer is different. We resolve the problem entirely in software, from £250, with no parts to wait for and a lifetime warranty on the work.
The eight makes below are the ones we see most often. Each links to a dedicated page covering that manufacturer’s specific AdBlue failure patterns, the warning messages you are likely to see and what the fix involves. That detail matters, because a Mercedes Sprinter with a failed NOx sensor is a very different starting point from a Ford Transit with a dosing pump fault, even though both end up with the same countdown on the dash. Knowing where each system tends to fail is what lets us quote accurately and complete the job in a single visit.
Everything we do is mobile. Our technicians attend homes, workplaces, yards and safe roadside locations across London, Surrey, Sussex and Kent with everything needed to finish the work on the spot. You can check our areas covered page for your postcode, read more about our AdBlue repair and AdBlue delete services, or see our NOx sensor delete page if a sensor fault is behind your warning light.
If your vehicle is not listed below, do not worry. The makes on this page are simply the ones we handle most, not a limit on what we cover. Send us your registration through the quote form, browse the FAQ for common questions, or call 0207 046 1823 and we will confirm what we can do for your exact model.
By Manufacturer
The Eight Makes We See Most
Every manufacturer’s AdBlue system fails in its own way. Choose your make below for the failure patterns, warning messages and the software fix that solves them for good.

Mercedes
Sprinter, Vito and C, E and GLC diesels are regulars for NOx sensor failures and the start prevention counter.
Mercedes AdBlue Fixes
BMW
Later 2.0d and 3.0d engines suffer NOx sensor and dosing faults with warnings that keep returning after a top up.
BMW AdBlue Fixes
Ford
The Transit is the vehicle we see more than any other, usually with pump, injector or pressure faults behind a countdown.
Ford AdBlue Fixes
Vauxhall
Insignia, Vivaro and Movano owners know the AdBlue system fault message well. Heaters, sensors and dosing all trigger it.
Vauxhall AdBlue Fixes
Peugeot
BlueHDi engines in the Boxer, Expert and 3008 are prone to urea tank and pump unit failures that cost four figures at a dealer.
Peugeot AdBlue Fixes
Citroen
Sharing the BlueHDi system with Peugeot, the Berlingo, Dispatch and Relay develop the same tank, sensor and injector problems.
Citroen AdBlue Fixes
Jaguar
Ingenium diesel XE, XF and F-Pace models throw DEF quality warnings and restricted performance, often with a no-start countdown.
Jaguar AdBlue Fixes
Range Rover
TDV6 and SDV6 Range Rovers and Discoverys suffer DEF dosing and quality faults that dealers struggle to resolve for good.
