Then set this page aside a moment, keep the ignition and engine off, and ring 0333 366 0103. A drain and a thorough flush, carried out just where your car stands in Barcroft, is usually all it takes if found before the motor runs. Not happened yet? Further down, the rest of the page covers the why it happens and the how to avoid it for good. ## AdBlue in a diesel car: two tanks, two fillers Diesel goes to your engine — but plenty of modern diesels seen round Barcroft and Harewood Hill hold another fluid as well. Your exhaust, not the engine, is where AdBlue goes: sprayed into the fumes to fresh them, from a separate tank. Each tank comes with a filler of its own. Other motors put the AdBlue filler in your boot or under the bonnet; plenty of others have both side by side under one flap. The diesel side is filled at the petrol pump all the time. Seldom topped up, AdBlue normally comes from a bottle, poured by a driver who has to stop and think what filler it needs. The slip lives in that gap. ## How AdBlue in your diesel tank takes place around Barcroft Rarely is it carelessness: normally three things coincide. Haste follows from the warning. The car warns you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up gets done in a rush, before work on a drive off Barcroft, or heading home in the car park at The Cross Roads. New-to-you cars come next, as well. Rentals, new motors and company cars put their fillers in new places, and habit reaches for the cap it used on the old one. A spouted bottle finds no resistance at a diesel filler any more than at an AdBlue one. So the pour, after begun, keeps on. The same few seconds settle it, in the middle of Barcroft or out in Cross Roads. ## Which filler is for AdBlue, and which for diesel? A few seconds is all the checks take — so check them before you tip anything, on a driveway in Flappit Spring or a forecourt in Barcroft. - Check the cap instead of going by position: AdBlue ones are frequently blue or marked "AdBlue", and diesel ones usually aren't. - Look at the size: the smaller neck is, on many cars, the AdBlue one. - Lift the filler flap and look for a label — many motors mark what goes in each inlet just there. - The handbook says which it lives if your filler is not next to your diesel cap: the boot, or under the bonnet. - The previous driver knows. Ask when you pick up a hire car or fleet car — at Keighley's car park, say — not when the warning comes on. ## Keeping AdBlue out of the diesel tank when you top up Wherever across West Yorkshire the light comes on, this is a routine for that day. - Pull in on level, motor off, with time to spare — never rushing on the side of Myrtle View. - Silly as it sounds, speaking "AdBlue" aloud while you unscrew the cap does the trick — after you have located your filler and read the cap. - Both under a single flap? So make sure the lid on the diesel side stays shut before lifting the bottle. - Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only after that, start your car: close the cap, check a second time, and make sure your diesel cap was never opened. If at step two or three you find you have already poured into your diesel side, stop there. Don't carry on to stage five. ## Already put AdBlue in your diesel tank around Barcroft? Then the order of things is short. Do not start your motor. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. Diluting it with more diesel fails, because AdBlue settles to the base rather than blending — and that is where the fuel is pulled from. If you are on a forecourt, whether it is the Shell or the another forecourt nearby, ask the staff to help push the vehicle clear of the pump. Your own drive in Barcroft is where it stays. Stop as soon as it is safe and switch off, if the motor has already run. The next exit means the place to leave when you are on the M606, under 10 miles from Barcroft. Mileage counts — a short hop across Barcroft makes a smaller job than heading under 10 miles towards Bradford — so tell us about how far it went. ## Barcroft: what occurs when we get there We come to the car wherever it has stopped, whether that's outside Lees Primary School, close to St James or on your own driveway. Both the work and the price rest on three answers — what liquid, what quantity, and whether it's run — so we ask. You hear that quote by phone, before anyone heads out. The system is then purged thoroughly, after the tank is drained. Not like petrol, AdBlue leaves crystals and attacks some fuel-system metals, and none of it clears out unaided. Hence it counts more. Testing is last: before that, clean diesel is added, and the fuel filter is cleaned or replaced as needed. Your engine is fired up next and tested to confirm it runs smoothly, all before we head off. With pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs in which your motor has not run need roughly half an hour once our technicians arrive. The insurer will ask for an engineer's report and your VAT invoice, and you get both once this job is done. Payment is on the day, with no money upfront. While we travel, take a look at your insurance documents; many include cover for misfuelling. ## About Barcroft itself Barcroft is a suburban area situated on the outskirts of Bradford, near the lakeside in West Yorkshire.
