In Boughton Heath, finding it before your engine turns usually means draining and a full flush on the spot. If you're reading before it has happened, the rest of this page is about why it takes place and how to make sure it doesn't. ## AdBlue in a diesel car: two tanks, two fillers Many current diesels on the roads around Boughton Heath and Christleton carry two liquids, not one. Diesel goes to the motor. Its own tank holds it, and from there it goes to your exhaust, and there a spray cleans the gas. There's a filler for every tank. Under one flap, next to each other: that's the arrangement on a lot of motors. On others, AdBlue's filler is under the bonnet or in the boot instead. Diesel goes in on each filling station visit, week in, week out. Rarely topped up, AdBlue usually comes from a bottle, poured by someone who has to stop and think which filler it needs. The mistake lives in that gap. ## AdBlue in your diesel tank in Boughton Heath: how it occurs Carelessness rarely explains it. What does is three things coming up together. Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up happens quickly, before work on a driveway off Waters Reams, or heading home in the car park outside The Peacock. Next, your hand reaches for the cap it would have used on the old motor — since a hire car, a new vehicle or a company car puts the fillers where your last one did not. Nothing halts the pour once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Dee Banks or the heart of Boughton Heath: it takes the same few seconds in both. ## How to tell the AdBlue filler from the diesel one Before you pour anything, whether on a driveway in Littleton or a forecourt around Boughton Heath, check these. They take a couple of seconds. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap normally is not. Read it instead of going by position. - On plenty of vehicles, the size tells: AdBlue gets the smaller filler neck. - The flap. Look inside your fuel flap for a label. Many motors say there which fuel goes where. - In the boot or under the bonnet: that's where the filler sits if it is not by the diesel cap, and the handbook tells you which. - 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 at Chester. ## Keeping AdBlue out of your diesel tank when you top up On the day the light appears — anywhere you are in Cheshire — a simple routine to follow. - Turn off after you park — level ground, motor stopped, and never in a rush beside Round Hill Meadow at the roadside. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Before starting the vehicle, close the cap and look a second time that your diesel cap never came off. Stop there if you find, at step two or three, that you have already poured into your diesel side. Don't carry on to step five. ## Already put AdBlue in the diesel tank in Boughton Heath? Then the order of things is short. Don't start the motor. The fuel pump starts on many diesels as soon as the ignition is switched on — and so keep it off. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from. At a forecourt — Sainsbury's, Shell or any other — the attendants will normally help push your car away, if you ask. Leave it where it is if you are on your own drive around Boughton Heath. When your engine has been run already, pull over somewhere safe then switch the car off. Come off the M53 — under 3 miles out of Boughton Heath — at the first exit. Tell us roughly how far it went: a run towards Chester, under 3 miles away, is a bigger job than a short hop across Boughton Heath. ## Our arrival around Boughton Heath, and what takes place next Anywhere the car came to rest, whether outside Boughton Heath Academy, beside 1st Christleton Scout Group or on your own drive, our van travels to it. Both the work and the price depend on three answers — which fluid, what amount, and whether it's run — so our engineers ask. That price comes over the phone, before any van leaves. Your system is then purged thoroughly, once your tank is drained. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. The filter cleaned or, if it must be, swapped; clean diesel in; and then a test of the car. Before leaving, our technicians start the engine and make sure that it's running properly. Most jobs are finished in about half an hour once our technicians arrive, as long as the engine hasn't run — and the pumps our engineers use are fine on a busy forecourt yet quiet after dark beside a house. The insurer usually wants the engineer's report and the VAT invoice, and you get both once this job is done. Payment comes on the day, with no money upfront. Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way. ## About Boughton Heath, for a moment Boughton Heath is a suburban area located on the outskirts of Chester, situated near the River Dee in Cheshire.
