AdBlue top-ups

Low AdBlue warning? We top up your car’s AdBlue and advise on the warning message and next step.

What is AdBlue?

AdBlue is a fluid used by some diesel cars to reduce harmful exhaust emissions. It has its own tank, separate from the diesel fuel tank.

Top-up or diagnostic check?

We check the vehicle’s requirements and top up the AdBlue tank where needed. The warning message helps us decide whether that is the right starting point.

Top-up or diagnostic check?
Message or situationNext step
Low AdBlue levelArrange the correct fluid top-up for the vehicle.
Persistent warning or emissions-system faultArrange diagnostics; dosing equipment, sensors or other components may need investigation.
Distance-to-no-restart countdownTell us the exact wording and distance shown so we can advise.

A top-up alone will not repair a system fault. The required quantity and recognition of a top-up vary by vehicle.

The right fluid, in the right tank

AdBlue has a dedicated filler and must not be added to the diesel fuel tank. When enquiring, send the registration and recent top-up details so we can understand whether the level or a continuing fault needs attention.

Frequently asked questions

Does every diesel car use AdBlue?

No. It depends on the vehicle and its emissions system. Give us your registration if you are unsure.

Can I book a top-up between services?

Yes. Call to arrange a visit and confirm the cost. You do not need to wait for your next service.

What if there is a restart countdown?

Contact us promptly and tell us the exact message and remaining range. A low level or system fault can prevent restarting once the countdown reaches zero. We will advise on the next step.
