In that case put this page down a moment, keep your ignition and motor off, then ring 0333 366 0103. Caught before the motor runs, it's generally a drain and a thorough flush, done where the car is around Church Garforth. Reading in advance? In that case the rest covers how it comes about and how to prevent it happening at all. ## AdBlue in a diesel car: two tanks, two fillers Not one liquid but two: that's how many modern diesels near Church Garforth and Lidgett carry, with diesel feeding the engine. AdBlue's own tank keeps it, and from there it goes to the exhaust, and there spraying cleans the gas. Each tank has its own filler. Plenty of cars share a single flap for both, while some put the AdBlue filler to the boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. The AdBlue side is fuelled far less frequently, normally from a bottle, and usually by someone who has to stop and think where it goes. It is in that gap that the error lives. ## How AdBlue in your diesel tank takes place in Church Garforth Rarely is it carelessness: normally three things line up. The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Oak Crescent before work, or in the car park outside The Podger on the way home. Next, the hand reaches for the cap it knew on the old car — because a hire car, a new car or a company car places the fillers where your last one did not. A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. And so the pour, after started, carries on. The same few seconds settle it, in the middle of Church Garforth or out in East Garforth. ## Telling the AdBlue filler from the diesel filler A few seconds is all the checks take — so check them before you tip anything, on a driveway in West Garforth or a forecourt in Church Garforth. - Colour and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not its position. - The size. On many motors the AdBlue filler neck is the smaller of the two. - Open the filler flap and look for a label — many vehicles mark what goes in which inlet just there. - The handbook says which it lives if the filler is not next to your diesel cap: the boot, or under the bonnet. - Picking up a hire or company car, perhaps at the car park at Garforth? Check with the person who drove it last before leaving, rather than once the light comes on. ## Topping up AdBlue without it reaching the diesel tank When the light goes on, anywhere in West Yorkshire, use this routine. - Turn off after you park — level ground, engine stopped, and never in a rush beside Croft Foulds Court on the verge. - Find the AdBlue filler, read the cap, and say the word "AdBlue" out loud while unscrewing it. It sounds daft. It does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the car on. - Slowly is best, through the bottle's own spout, until it's full or the bottle is empty. - Only then, start the car: close the cap, check once more, and make sure the diesel cap was never opened. If at step two or three you find you have already poured into your diesel side, stop there. Do not go on to stage five. ## Church Garforth: already put AdBlue in the diesel tank? The short order of things, beginning with not starting your motor. Leave the ignition off as well, because on plenty of diesels switching it on alone starts the fuel pump. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is pulled from. Ask the attendants to help push your car clear of the pump if you are on a forecourt — the Tesco, the Esso or somewhere else. Your own driveway around Church Garforth is where it stays. Stop as soon as it is safe then switch off, if your motor has already run. The next exit is the place to leave when you are on the M1, under a mile from Church Garforth. Distance matters — a quick hop across Church Garforth makes a smaller job than driving under 10 miles to Leeds — so tell us about how far it went. ## Church Garforth: what occurs when our engineers turn up The van reaches the car anywhere it stopped — your own driveway, near St Mary's, or outside St Benedict's Catholic Primary School. Those replies decide the work and the quote, so our technicians ask what was put in, roughly how much, and whether it's run. The price is given over the phone, ahead of any van leaving. Next: draining, then a thorough flush of the entire system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. After the fuel filter has been cleaned — or replaced, where needed — fresh diesel is added, and finally your vehicle gets tested. We don't leave until it has been started and is running smoothly. If the engine has not run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is part of many insurance policies — so make use of the wait to check yours. ## About Church Garforth Church Garforth is a suburban area in West Yorkshire, situated approximately 7 miles east of Leeds and 166 miles north of London.
