Around Low Westwood, catching it before your motor runs usually leaves draining and a thorough flush where it stands. Not happened yet? Further down, the page explains the why it happens and the how to prevent it altogether. ## AdBlue in a diesel motor: two tanks, two fillers Not one fluid but two: that is what plenty of modern diesels around Low Westwood and Ebchester run, with diesel feeding the motor. Stored in a tank of its own, AdBlue is sprayed into your exhaust gas and cleans it. Each tank has its own filler. Many of cars share a single flap for the two, whereas some put the AdBlue filler to the boot or under the bonnet. Diesel goes in on every forecourt visit, week in, week out. The AdBlue side is filled far less frequently, normally from a bottle, and usually by someone who has to stop and think where it goes. It is in that gap that the error happens. ## Low Westwood: how AdBlue in your diesel tank happens Seldom is it carelessness: normally three things coincide. On a drive off A694 before work, or in the car park outside Blackhall Mill Working Mens Club on the way home: that is where the hurried top-up happens. Why the rush? As AdBlue runs low the car tells you, and if it is gone, limp mode kicks in. Then, your hand reaches for the cap it would have used on the old car — because a hire car, a new motor or a company car puts the fillers somewhere your last one did not. Nothing stops 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. Hamsterley or the middle of Low Westwood: it is the same few seconds either way. ## Telling the AdBlue filler from the diesel filler Before you pour anything, whether on a drive in The Dene or a forecourt in Low Westwood, check these. They take a few seconds. - Position can mislead; the cap doesn't. AdBlue ones are often blue or carry the word "AdBlue" — diesel caps usually do not. - Check the size: the smaller neck is, on plenty of vehicles, the AdBlue one. - Look inside your fuel flap: plenty of motors carry a label there saying which fuel goes where. - The handbook. If your filler is not by the diesel cap, it's in the boot or under the bonnet, and the handbook says which. - Check with the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park outside Prudhoe. ## Keeping AdBlue out of your diesel tank when you top up Wherever across Durham the light comes on, here is a routine for the day. - Switch off once parked — flat ground, engine stopped, and not in a rush by Derwent Crescent on the verge. - Daft as it sounds, saying "AdBlue" out loud as you unscrew the cap does the trick — after you have located the filler and read it. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave it on. - Finish once that tank is topped up or the bottle is empty; before that, pour gently through the own spout. - Only after that, start the vehicle: close the cap, check once more, and make sure your diesel cap was never opened. Spot at stage two or three that it's already gone into the diesel side? Then stop just there. Don't go on to step five. ## Put AdBlue in your diesel tank in Low Westwood already? Short list, then. First: the motor remains unstarted. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch the car on. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where your fuel is pulled from. The attendants at Esso, Tesco or another forecourt will usually help pushing the vehicle clear if asked. Your own drive in Low Westwood is the place it stays. Where your engine has been run already, pull over safely and switch it off. Come off the Central Motorway East — under 10 miles out of Low Westwood — at the next junction. A short hop across Low Westwood is a smaller job than a run towards Newcastle upon Tyne, under 15 miles away, so tell us roughly how far it went. ## Our arrival in Low Westwood, and what happens next The van comes to the car wherever it stopped — your own driveway, near Christ Church Hamsterley, or outside Ebchester CofE Primary School. Our engineers ask what got in, roughly how much, and whether it has run, since those answers decide this work and the price. That price comes on the call, before any van leaves. Then the tank is drained and your system purged thoroughly. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and neither washes away by itself. Hence it matters more. Filter flushed or, if it must be, replaced; clean diesel in; and then a test of your vehicle. We do not leave until it has been started and is running correctly. Most jobs are done in roughly half an hour once our engineers get there, as long as your engine has not run — and the pumps our engineers use are fine on a live forecourt and quiet after dark beside a house. Your insurer usually wants an engineer's report and your VAT invoice, and both are yours once the job is done. Payment is on the day, with no money upfront. Misfuelling cover is part of plenty of insurance policies — so make use of the wait to check yours. ## About Low Westwood, briefly Low Westwood is a village in County Durham, situated on the riverside at an elevation of 87 metres, with terraced housing being the predominant type of accommodation.
