In that case put this page aside a moment, keep your ignition and motor off, then ring 0333 366 0103. Normally, if the motor has not run, it is drained and fully flushed where your car is around Bemerton Heath. Not happened yet? Below, the rest of the page covers the why it takes place and the how to avoid it altogether. ## Why does AdBlue in a diesel motor need its own filler? Plenty of modern diesels on the roads around Bemerton Heath and Fugglestone St Peter carry two liquids, not one. Diesel goes to the engine. The exhaust, not your engine, is where AdBlue ends up: sprayed into the fumes to fresh them, from its own tank. Each tank comes with one filler of its own. Under one flap, next to each other: that's the layout on many motors. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. Filling the diesel side at the petrol pump happens constantly. A driver who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and far less often. The mistake grows in the gap between them. ## Bemerton Heath: how AdBlue in the diesel tank happens Seldom 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 drive off Woodside Road before work, or in the car park at The White Horse on the way home. Then your car is new. A hire car, a new car 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. Nothing halts the pour after it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Westwood or the middle of Bemerton Heath: it is the same few seconds either way. ## Telling the AdBlue filler from your diesel filler Before you tip anything, whether on a driveway in Churchfields or a forecourt in Bemerton Heath, check these. They take a few seconds. - Read the cap rather than going by position: AdBlue caps are often blue or marked "AdBlue", and diesel ones usually aren't. - Look at the size: the smaller filler neck is, on many cars, the AdBlue one. - Open the flap and look for a label — plenty of vehicles show which belongs in each filler right there. - The handbook says which it is if your filler isn't next to your diesel cap: the boot, or under the bonnet. - The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Salisbury, ask before you leave, not when the light comes on. ## How to top up without AdBlue in the diesel tank Anywhere around Wiltshire the light comes on, here is a routine for the day. - Turn off after you park — flat ground, engine off, and not in a rush beside Pembroke Road at the roadside. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, yes, yet it works. - Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Only after that, start your car: close the cap, check a second time, and make sure the diesel cap was never opened. Stop there if you find, at stage two or three, that you've already poured into your diesel side. Leave out step five entirely. ## Put AdBlue in your diesel tank around Bemerton Heath already? Then the order of things is short. Don't start your motor. The fuel pump runs on plenty of diesels as soon as the ignition is switched on — so leave it off. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from. On a forecourt — Texaco, Shell or another — the staff will usually help roll your car clear, if you ask. If you are on your own driveway in Bemerton Heath, leave it where it is. Where your motor has been run by now, pull over safely and switch the car off. On the M27, under 25 miles from Bemerton Heath, that means the next exit.

Unstarted vehicles usually mean a half-hour job from arrival. The kit is safe on a live forecourt, and hushed enough for a driveway late at night.
