In that case set this page down a moment, keep the ignition and engine off, and call 0333 366 0103. In Stretton, catching it before the engine turns usually means a drain and a thorough flush where it stands. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't. ## AdBlue in a diesel car: two tanks, two fillers Plenty of modern diesels on the roads around Stretton and Rolleston on Dove carry two liquids, not one. Diesel goes to your motor. Its own tank keeps it, and from there it is sent to the exhaust, where spraying treats the fumes. Each tank has its own filler. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. At the pump, the diesel side is topped up constantly. Far less frequently, the AdBlue side is filled — mostly from a bottle, by someone working out where it goes. That gap is where the error lives. ## How does AdBlue in the diesel tank occur in Stretton? Carelessness rarely explains it. Instead is three things lining up together. Hurry comes from the warning. The vehicle warns you as AdBlue runs low, and an empty tank puts it into limp mode — so the top-up happens quickly, before work on a driveway off Church Road, or heading home in the car park at The Junction. Unfamiliar motors come second, as well. Rentals, new motors and company vehicles place their fillers differently, and habit reaches for the cap used on the old one. Lastly, the spout fits: a diesel filler or AdBlue filler, it goes in as readily, and once the tip begins, nothing halts it. The same few seconds settle it, in the middle of Stretton or out in Horninglow. ## How to tell the AdBlue filler from the diesel one Before you pour anything, whether on a driveway in Egginton or a forecourt in Stretton, check these. They take a couple of seconds. - The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap normally is not. Read it rather than going by where it sits. - Check the size: the smaller neck is, on plenty of cars, the AdBlue one. - Open the flap and look for a label — plenty of cars mark what goes in which inlet right there. - In your boot or under the bonnet: that's where your filler sits if it's not by your diesel cap, and the handbook tells you which. - The previous driver knows. Ask when you pick up a rental or company car — from Burton-On-Trent's car park, perhaps — rather than when the warning appears. ## 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 and switch off. Not on a slope, not with your motor running, and not in a rush on the side of Bridge Street. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - The two under one flap? Then make sure the lid on your diesel filler stays closed before lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Shut the cap, and check again — confirm the diesel cap stayed closed throughout. Only then, start the car. Spot at step two or three that it's already gone into the diesel side? So stop right there. Don't go on to step five. ## Already put AdBlue in the diesel tank in Stretton? Brief order, then. First: your engine remains off. Keep the ignition off as well, since on plenty of diesels it by itself starts the fuel pump. Topping up with diesel will not thin it: rather than mixing, AdBlue drops to the bottom of your tank, right where the fuel is drawn from. On a forecourt — Esso, Shell or any other — the attendants will normally help roll the vehicle clear, when you ask. Your own driveway around Stretton is where it should stay. Stop as soon as it is safe then switch off, if your engine has already run. On the M42, under 15 miles from Stretton, that means the next junction. A short hop across Stretton is a smaller job than a run towards Derby, under 10 miles away, and so tell us roughly how far it went. ## What happens when we turn up around Stretton Outside William Shrewsbury Primary School, close to St Marys or on your own drive: wherever the car has stopped, our engineers come to it. What fluid got in, the amount, and if it ran: our engineers ask because those replies set the work and price. That price is given over the phone, ahead of any van leaving. The fuel system is then flushed thoroughly, once the tank is emptied. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and neither clears away unaided. Hence it matters more. The filter cleaned or, if it must be, replaced; clean diesel in; and then a test of your car. The engine is started next and checked to confirm it runs smoothly, all before our technicians head off. If the motor has not run, most jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. Paying is on the day, not upfront, and you are given the paperwork an insurer wants: an engineer report and a VAT invoice. Before we get there, have a look at your policy; many carry cover for misfuelling. ## About Stretton itself Stretton is a village in Staffordshire, situated on the riverside at an elevation of 54 metres, with semi-detached housing being the predominant type of accommodation.
