AdBlue already in your diesel tank? In that case set this page down a moment, leave your ignition and engine off, then phone 0333 366 0103. Caught before the engine runs, it's usually a drain and a thorough flush, done where the vehicle is around Westwood. Nothing happened yet? Further down, the rest of the page explains the reasons it happens and the ways to avoid it for good. ## Why does AdBlue in a diesel motor need its own filler? Diesel goes to the motor — but plenty of modern diesels driven around Westwood and Whitehall hold a second fluid too. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Every tank has a filler of its own. Some cars keep the AdBlue filler in your boot or under the bonnet; a lot more place the two side by side behind one flap. Topping up the diesel side at the petrol pump happens constantly. Someone who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and much less often. It's in the gap that the error lives. ## How does AdBlue in the diesel tank occur around Westwood? Three things tend to come together, and carelessness is seldom one of them. On a drive off Haine Cross Road before work, or in the car park outside Canterbury Bell on the way home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue runs low your car tells you, and once it is gone, limp mode kicks in. Then your car is unfamiliar. 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. No part halts the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Northwood or the middle of Westwood: it takes the same few seconds either way. ## Telling the AdBlue filler from the diesel filler Be it a Westwood forecourt or a drive over in Lydden, spend a few seconds on these before anything goes in. - Position misleads; the cap doesn't. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel ones normally do not. - On plenty of cars, the size tells: AdBlue has the smaller filler neck. - Open the filler flap and look for a label — plenty of cars mark what goes in which filler just there. - The handbook. If your filler isn't by your diesel cap, it is in the boot or under the bonnet, and the handbook says which. - Whoever had it before knows. Ask when you collect a rental or company car — at Ramsgate's car park, say — not once the warning comes on. ## AdBlue top-ups that never reach the diesel tank Anywhere around Kent the light comes on, here is a routine for the day. - Stop somewhere level, engine off, with time to spare — not hurried on the side of Westwood Road. - Daft as it sounds, speaking "AdBlue" aloud while you unscrew the cap works — once you've located your filler and read it. - The two behind one flap? So make sure the lid on your diesel filler stays closed ahead of lifting the bottle. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Before starting the car, close the cap and check a second time that the diesel cap was never came off. If at step two or three you find you have already poured into your diesel side, stop there. Don't go on to stage five. ## Put AdBlue in your diesel tank in Westwood already? What follows is a short order of things, starting with no starting your motor. The fuel pump starts on many diesels the moment your ignition is switched on — so leave it off. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from. The staff at Tesco, Sainsbury's or any forecourt will usually lend a hand to push the car away when asked. At home in Westwood? So your car remains put. Already started? Pull over when it's sensible, then turn off. Westwood lies under 25 miles from the M2; there, use the next junction. A short hop across Westwood is a smaller job than a run towards Canterbury, under 15 miles away, and so tell us about how far it went. ## When we turn up around Westwood, what occurs? By Dame Janet Primary Academy, near TK Maxx or on your own drive: wherever your car has stopped, our engineers come to it. Our engineers ask what got in, roughly how much, and whether it's run, since those answers decide this work and the quote. You get that price by phone, before anyone heads out. Draining the tank comes next, then a thorough flush of your system. Not like petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither clears away by itself. That is why it counts more. A test comes at the end: before that, fresh diesel goes in, and the fuel filter is cleaned or changed as needed. We do not leave until it has been fired up and is running properly. Unstarted vehicles usually mean a half-hour visit after the moment we arrive. The equipment is fine on a live forecourt, and hushed enough for a residential street late at night. Paying happens on the day, not upfront, and you are given the documents your insurer wants: an engineer's report and a VAT invoice. Wrong-fuel cover is part of many insurance policies — so use the wait to check yours. ## About Westwood and where it is Westwood is a suburban area in Kent, situated near the coast and approximately 14.9 miles from Canterbury.
