01
The problem
Common AdBlue messages on diesel cars and vans
What the warning means
What the message is telling you
'No start in 500 miles' means a fault or low level has been confirmed and it is time to act. 'No start in 100 miles' leaves little margin, so plan to stay where help can reach you. A full tank with the warning still on points to a level or quality sensor, a heater, or a stored fault the refill has not cleared. 'AdBlue system malfunction' means the car has found a fault in the system. Reduced power or limp mode means the engine is protecting itself, often AdBlue but not always. A vehicle that will not restart has reached zero. A NOx sensor warning means the sensors that check the SCR system are reporting a problem.
Problems after a previous repair
If the warning came back after a part was changed, the cause may be elsewhere: wiring, a second faulty part, or a fault that was cleared without being fixed. Tell us what was done.

What we offer
What we do
Do this first
Note the number: photograph the message and the miles left. Do not keep turning the engine off and on to test it, as on many vehicles the no-start applies at the next restart once the count hits zero. If the tank is low, fill it with fresh AdBlue (ISO 22241) and drive for a few minutes; if the message says malfunction, refilling will not clear it. Then send us the registration, location and photo by WhatsApp or call.
Can it be sorted at the roadside?
Most diagnosis can be done wherever the vehicle is: home, work or roadside, as long as it is safe to work there. If the vehicle is immobilised, tell us so we can plan the visit.
What we actually offer
We don't replace AdBlue parts. Our service is AdBlue Delete, also called AdBlue Removal: a software change that stops the engine running or monitoring the AdBlue system and clears the related warnings and countdown. We check your vehicle is suitable before quoting.
No Fix, No Fee
If we cannot complete the job, there is no charge. Lifetime Software Warranty: applies to the software work on that vehicle. If the covered software work develops a problem, we correct it again. Later software updates or recalls void the warranty, and callout charges are not covered.
Normal appointments and 24/7 emergencies
Standard hours are Monday to Sunday, 8 AM to 8 PM. 24/7 Emergency Callouts Available.
- The AdBlue warning and restart countdown are cleared
- No more buying or topping up AdBlue fluid
- Done at the vehicle, wherever it is parked
- No Fix, No Fee: if the job cannot be completed, you pay nothing
- Eligible work carries a lifetime software warranty

Ask an AdBlue Specialist on WhatsAppQuestions customers ask us
Why is the AdBlue warning still there after refilling?+
The car may have stored a fault, or the level sensor may not be reading. A short drive sometimes clears a pure low-level warning. If not, send us the message and registration and we'll tell you whether our Delete and Removal service is suitable.
Can you help if the countdown has reached zero?+
Often, yes. We come to the vehicle where it is.
Can a NOx sensor cause a no-start countdown?+
Yes, on most vehicles.
How much does emergency attendance cost?+
It depends on location and time. The emergency charge is confirmed before anyone sets off.
What do you need for a quote?+
Registration, postcode or location, mobile number and a photo of the warning.
Do you offer 24/7 emergency callouts?+
Yes. Our normal business hours are 8 AM to 8 PM, Monday to Sunday, and we also offer a 24/7 emergency callout service across England. We confirm the price with you before a technician is sent.
