If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and the ignition off and phone 0333 366 0103. In Burndell, catching it before your engine turns normally means a drain and a full flush on the spot. Here in advance? Then the rest explains why it comes about and what to stop it happening at all. ## AdBlue in a diesel vehicle: two tanks, two fillers Plenty of modern diesels on the roads round Burndell and North End carry two liquids, not one. Diesel goes to the motor. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. There's a filler for each tank. Other vehicles keep the AdBlue filler in the boot or under the bonnet; a lot of others have the two together under one flap. The diesel side is topped up at the petrol pump all the time. A driver who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less commonly. The mistake lives in that gap. ## How does AdBlue in the diesel tank happen in Burndell? Seldom is it carelessness: normally three things line up. Haste follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up gets done quickly, before work on a driveway off Northwood View, or heading home in the car park at The Oystercatcher. Then the vehicle is new. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand gets to for the cap it would have used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour once it has started. Whether it takes place in Yapton or the middle of Burndell, it's the same few seconds. ## Telling the AdBlue filler from the diesel filler Look at these before pouring, at a forecourt in Burndell or a driveway out in Ford. Seconds, no more. - The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap normally isn't. Read it instead of going by where it sits. - Look at the size: the smaller filler neck is, on plenty of cars, the AdBlue one. - Look inside the fuel flap: many vehicles carry a label there saying which fuel goes where. - Can't see it beside your diesel inlet? Then look below the bonnet or inside the boot — the owner's manual will say where. - Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park at Ford. ## AdBlue top-ups that never reach your diesel tank Wherever around West Sussex the light comes on, this is a routine for that day. - Not in a rush on the side of Linseed Way, not on a slope, not with your motor running: park and switch off properly. - Daft as it sounds, saying "AdBlue" out loud while you unscrew the cap works — after you have located your filler and read it. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the car on. - Finish once the tank is topped up or the bottle is empty; before that, tip gently using the own spout. - Before starting the car, close the cap and look a second time that the diesel cap was never opened off. Find at stage two or three that it's already gone into the diesel side? Then stop just there. Never go on to stage five. ## Put AdBlue in the diesel tank in Burndell already? Brief list, then. First: your motor remains off. Leave the ignition off as well, because on plenty of diesels switching it on alone starts the fuel pump. Topping up with diesel won't dilute it: instead, AdBlue sinks to the bottom of that tank, right where fuel is taken from. Ask the attendants to help push your car clear of the petrol pump if you're at a forecourt — the Tesco, the Esso or anywhere else. Your own driveway in Burndell is where it stays. When the motor has been run already, pull over somewhere safe then turn the car off. Leave the Waterlooville Bypass — under 25 miles out of Burndell — at the next exit. Mileage counts — a quick hop across Burndell is a smaller job than heading under 10 miles to Chichester — so tell us roughly how far it went. ## Burndell: what occurs when our technicians arrive By Yapton CE Primary School, near RNAS/RAF Ford Memorial or on your own drive: wherever the car has stopped, our engineers come to it. The answers determine this work and the quote, and so our technicians ask what got in, about how much, and whether it's run. You hear that price by phone, before anybody heads out. Emptying the tank comes next, then a full flush of the system. Unlike petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither clears away by itself. That is why it counts more. Testing comes last: before that, clean diesel goes in, and the fuel filter is cleaned or replaced as needed. The motor is started next and checked to be sure it runs smoothly, all before our engineers leave. Unstarted cars mostly need a half-hour job from arrival. The kit is fine on a live forecourt, and quiet enough for a driveway late at night. Your insurer usually wants an engineer's report and your VAT invoice, and both are yours once this job is done. Payment comes on the day, with no money upfront. Plenty of insurance policies include misfuelling cover, so it's worth checking yours while we are on the way. ## About Burndell itself Burndell is a coastal locality in West Sussex, situated near the cities of Chichester and Bognor Regis.
