Leave your motor and ignition off then ring 0333 366 0103 first — the rest can wait when AdBlue is already in your diesel tank. In Harley Wood, catching it before your motor turns normally means draining and a full flush where it stands. Nothing happened yet? Below, the page covers the reasons it happens and the ways to avoid it altogether. ## AdBlue in a diesel car, and its separate tank Many modern diesels around Salford, as well as Harley Wood, carry on two fluids; your motor takes just your diesel. The exhaust, not your engine, is where AdBlue goes: dosed into the fumes to fresh it, from its own tank. Each tank has its own filler. Plenty of cars share a single flap for the two, while some move the AdBlue filler to your boot or under the bonnet. The diesel side is filled at the petrol pump all the time. Much less often, the AdBlue side is topped up — mostly from a bottle, by a person thinking about where it goes. The mistake lives in that gap. ## Harley Wood: how AdBlue in the diesel tank happens It's rarely carelessness. Three things tend to line up. First, the warning. Low AdBlue triggers a message from the vehicle, and letting it run dry leads to limp mode — hence a rushed top-up, maybe before work off Fern Valley Chase, or at Hare And Hounds on the way home that evening. Unfamiliar vehicles come second, as well. Hire cars, new motors and company motors place their fillers in new places, and the hand goes for the cap used on the old one. Third, the bottle goes in: diesel filler or AdBlue filler, it goes in as readily, and after the tip starts, nothing stops it. The same few seconds settle it, in the middle of Harley Wood or out in Lydgate. ## How to tell the AdBlue filler from the diesel one Look at these before pouring, on a forecourt around Harley Wood or a drive out in Priestwell. Seconds, that's all. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". The diesel cap usually is not. Read it instead of going by where it sits. - Many motors give AdBlue the smaller neck of the two. - The flap. Look inside the fuel flap for a label. Many cars say there which fuel goes where. - Can't see it beside the diesel filler? Then check below the bonnet or in the boot — the owner's manual will say which. - The previous driver will know. Ask when you collect a rental or company car — at Todmorden's car park, perhaps — rather than when the warning appears. ## Topping up AdBlue without it reaching your diesel tank For the day the warning appears — wherever you are around West Yorkshire — a routine to follow. - Pull in on level, motor off, with time in hand — never hurried on the side of Sigget Lane. - Daft as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — after you have found your filler and read it. - Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Close the cap and check once more. Make sure the diesel cap was never opened. Only then start your car. If at stage two or three you find you have already poured into your diesel side, stop there. Don't go on to stage five. ## Harley Wood: already put AdBlue in the diesel tank? Do not start your engine: that's where the short order of things starts. On many diesels the ignition alone runs the fuel pump, and so do not switch it on. Diluting it with more diesel won't work, because AdBlue settles to the base instead of blending — and that's where your fuel is pulled from. Ask the staff to help roll the vehicle clear of the pump if you are at a forecourt — the Shell, the Texaco or anywhere else. If you're on your own driveway in Harley Wood, leave the vehicle where it is. Already run? Pull over once it's sensible, then turn off. The next junction is where to leave if you're on the M62, under 10 miles from Harley Wood. Distance counts — a quick hop across Harley Wood is a smaller job than driving under 25 miles towards Bradford — so say roughly how far it went. ## When our technicians turn up in Harley Wood, what occurs? Anywhere your car has stopped, be it by Castle Hill Primary School, beside Todmorden Sports Centre or on your own drive, the van travels to it. Both the work and the quote depend on three answers — what liquid, what quantity, and whether it has run — so we ask. During the call itself, you hear the quote — ahead of dispatch. Then the tank is cleared and the system purged thoroughly. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of it washes out by itself. Hence it matters more. Testing comes last: before that, fresh diesel goes in, and the filter is cleaned or replaced as needed. The motor is started next and tested to confirm it runs smoothly, all before our engineers leave. Unrun cars usually need a half-hour job after arrival. The equipment is safe on a busy filling station, and quiet enough for a residential street after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth looking at your policy as the van travels to you: misfuelling cover is included with plenty of policies. ## About Harley Wood, briefly Harley Wood is a suburban area in West Yorkshire, situated near the riverside and surrounded by nearby places such as Lydgate and Hole Bottom.
