Frequently Asked Questions
Outside Devon, we book an independent mobile technician from our national network to come to you in Harpenden, and manage the job for you. Call with your postcode and we'll tell you straight away who can get to you.
AdBlue is widely sold in cans at fuel stations and motor factors, and many larger stations on main roads have it at the pump. If the warning stays on after a correct top-up, the problem is a fault rather than the level.
It depends on the fault, the vehicle and whether parts are needed, so we do not publish prices. Call with your reg and the warning message and we will quote for your vehicle.
