Caught before the motor runs, it's generally a drain and a thorough flush, done where the vehicle is in Biddulph Moor. Here in advance? Then the rest covers how it comes about and how to stop it ever happening. ## Why does AdBlue in a diesel motor need its own filler? No single liquid but two: that's what many newer diesels around Biddulph Moor and Cowall Moor run, with diesel for your motor. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. There is a filler for each tank. Other motors keep the AdBlue filler in the boot or under the bonnet; plenty of others place both side by side under one flap. Diesel gets filled at every forecourt call-out, again and again. Rarely topped up, AdBlue normally goes in out of a bottle, tipped by someone who must stop and think what filler to use. Mistakes happen in that gap between the two. ## How does AdBlue in your diesel tank take place around Biddulph Moor? Three things tend to come together, and carelessness is rarely one of them. Haste comes from the warning. The car warns you as AdBlue runs low, and an empty tank puts it into limp mode — so the top-up gets done quickly, before work on a driveway off Wraggs Lane, or heading home in the car park outside Rose & Crown. New-to-you motors come second, as well. Hire cars, new cars and company cars place their fillers in new places, and habit goes for the cap it used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour once it has started. The same few seconds decide it, in the middle of Biddulph Moor or out in Robin Hill. ## Telling the AdBlue filler from your diesel filler Before you tip anything, whether on a driveway in Rock End or a forecourt around Biddulph Moor, check these. They take a few seconds. - Colour and marking: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not where it sits. - Look at the size: the smaller neck is, on many vehicles, the AdBlue one. - Lift the filler flap and look for a label — many motors show what belongs in each inlet right there. - Can't see it next to your diesel filler? Then look below the bonnet or inside the boot — the handbook will say where. - Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Congleton. ## Keeping AdBlue out of your diesel tank when you top up A routine for the day the light comes on, wherever in Staffordshire that is. - Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of New Street. - Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud as you unscrew it. It sounds daft. It works. - The diesel cap remains on. When the two share a flap, make sure it's shut before the bottle comes up. - Finish once the tank is topped up or the bottle runs dry; until then, pour slowly using the built-in spout. - Shut the cap, then check again — making sure the diesel cap remained shut throughout. Only then, start the vehicle. Find at stage two or three that it's already gone into your diesel side? So stop just there. Stage five stays out. ## Already put AdBlue in the diesel tank around Biddulph Moor? Brief order, then. First: your motor remains unstarted. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. Diluting it with more diesel fails, because AdBlue settles to the base instead of blending — and that is where your fuel is sucked from. On a forecourt — Esso, Sainsbury's or another — the attendants will usually help push your car away, if you ask. At home around Biddulph Moor? Then the vehicle remains put. Where the engine has been run already, pull over somewhere safe and switch the car off. Biddulph Moor sits under 10 miles from the M6; there, take the first junction. Mileage matters — a quick hop across Biddulph Moor is a smaller job than driving under 10 miles to Stoke-on-Trent — so tell us roughly how far it went. ## Our arrival around Biddulph Moor, and what happens next Wherever your car has stopped, be it by Moor First School, beside Christ Church or on your own drive, the van travels to it. Both the work and our quote rest on three replies — what fluid, what quantity, and whether it's run — so our engineers ask. No one heads out before you've heard our price over the phone. The fuel system is then flushed thoroughly, once that tank is drained. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why the flush counts more with AdBlue than with petrol. Testing is last: before that, fresh diesel goes in, and the filter is cleaned or replaced if necessary. The engine is started next and checked to make sure it runs correctly, all before our technicians leave. Most jobs are done in roughly half an hour once our engineers get there, as long as the engine hasn't run — and the pumps we use are fine on a live forecourt yet quiet at night beside a house. Payment happens on the day, not upfront, and you receive the paperwork an insurer asks for: an engineer's report and a VAT invoice. Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way. ## About Biddulph Moor itself Biddulph Moor is a village in Staffordshire, situated near the River Biddulph and overlooking the surrounding countryside from an elevation of 291 metres.
