Then set this page aside a moment, leave the ignition and engine off, then phone 0333 366 0103. In Clannor Heath, finding it before the engine turns normally means draining and a thorough flush where it stands. Here in advance? Then what follows covers why it comes about and how to stop it happening at all. ## AdBlue in a diesel motor: two tanks, two fillers Plenty of current diesels on the roads round Clannor Heath and Blakelow carry two liquids, not one. Diesel goes to the engine. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. There's a filler on each tank. On a lot of vehicles 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 petrol pump, your diesel side is topped up constantly. The AdBlue side is filled far less frequently, usually from a bottle, and usually by someone who has to stop and think where it goes. The mistake grows in that gap between them. ## Clannor Heath: how AdBlue in the diesel tank occurs Three things tend to come together, and carelessness is seldom one of them. The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Dig Lane before work, or in the car park at The Elephant on the way home. Then the car is unfamiliar. A hire car, a new motor or a company car puts the fillers where your last one did not, and your hand gets to for the cap it would have used on the old one. Lastly, the bottle fits: diesel filler or AdBlue filler, it slides in just as easily, and once the pour begins, nothing halts it. It's seconds, be it out in Wybunbury or right in the centre of Clannor Heath. ## Telling the AdBlue filler from your diesel filler Look at these before pouring, at a forecourt in Clannor Heath or a drive over in Hough. A few seconds, no more. - Read the cap rather than going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel caps normally are not. - Plenty of cars give AdBlue the smaller filler of the two. - Lift the flap and check for a label — many motors show what goes in which filler right there. - Can't see it beside the diesel inlet? In that case check beneath the bonnet or inside the boot — the handbook says where. - Picking up a hire or company car, perhaps at the car park outside Crewe? Ask the person who drove the car last before you set off, rather than when the light comes on. ## AdBlue top-ups that never reach the diesel tank When the light goes on, anywhere across Cheshire, follow this routine. - Pull in somewhere level, motor off, with time in hand — never hurried on the side of Stock Lane. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, perhaps, but it works. - The diesel cap remains on. Where the two sit under a flap, confirm it's closed before lifting the bottle. - Finish when your tank fills or the bottle is empty; until then, tip slowly using its built-in spout. - Close the cap, and check once more — confirm the diesel cap remained closed throughout. Only then, start the car. Discover at the second or third stage that the bottle went into the diesel filler? That is where you stop. Do not go on to stage five. ## Already put AdBlue in your diesel tank in Clannor Heath? Short list, then. First: your motor remains off. On many diesels the ignition alone runs the fuel pump, and so don't switch it on. Topping up with diesel won't dilute it: instead, AdBlue sinks to the bottom of that tank, right where the fuel is drawn from. If you are on a forecourt, whether it's the the nearest petrol station or the Esso, ask the attendants to help roll the vehicle clear of the petrol pump. Leave it where it is if you're on your own drive in Clannor Heath. Where the engine has been run already, stop safely and switch it off. Come off the M6 — under 10 miles out of Clannor Heath — at the next junction. Tell us about how far it went: a run towards Stoke-on-Trent, under 15 miles away, is a bigger job than a short hop across Clannor Heath. ## Clannor Heath: what happens when our technicians get there The van reaches the car wherever it stopped — your own drive, beside Wybunbury Methodist Chapel, or outside Shavington Primary School. Our technicians ask what went in, roughly how much, and whether it has run, since those replies settle this work and the price. That quote is given on the call, before any van leaves. Your system is then rinsed thoroughly, after your tank is cleared. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more here than with petrol. Testing comes last: before that, clean diesel goes in, and the fuel filter is flushed or changed as needed. The engine is started next and tested to be sure it runs properly, all before we head off. If your engine has not run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night. Your insurer will ask for the engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way. ## About Clannor Heath, for a moment Clannor Heath is a suburban area in Cheshire, situated inland at an elevation of 61 metres, and is located near the cities of Stoke-on-Trent and Crewe.
