If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and your ignition off and phone 0333 366 0103. A drain and a full flush, carried out right where the car stands around Barford, is usually all it takes if found before your motor runs. Here in advance? Then the rest covers how it comes about and how to stop it ever happening. ## AdBlue in a diesel vehicle: two tanks, two fillers Plenty of current diesels on the roads about Barford and Colton carry two liquids, not one. Diesel goes to your 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. Each tank has its own filler. Plenty of vehicles share a single flap for the two, while some move the AdBlue filler to the boot or under the bonnet. Topping up the diesel side at the pump happens all the time. Seldom topped up, AdBlue normally goes in out of a bottle, tipped by a driver who has to stop and think what cap it needs. It's in that gap that the slip lives. ## How does AdBlue in your diesel tank happen around Barford? Carelessness rarely causes it. What does is three things lining up together. On a driveway off Chapel Street before work, or in the car park outside the pub in the village heading home: that is where the hurried top-up happens. Why the rush? As AdBlue runs low your car warns you, and once it's empty, limp mode follows. Unfamiliar cars come next, too. Hire cars, new motors and company motors place their fillers differently, and habit reaches for the cap it used on the old one. A spout-topped bottle finds no obstacle at a diesel filler any more than at an AdBlue one. And so the pour, after started, keeps on. It's seconds, whether out in Wramplingham or bang in the centre of Barford. ## Telling the AdBlue filler from your diesel filler Be it a Barford forecourt or a driveway over in Marlingford, spend a few seconds over these before any goes in. - Position misleads; the cap doesn't. AdBlue ones are often blue or bear the word "AdBlue" — diesel caps usually don't. - Plenty of vehicles fit AdBlue the smaller filler of the two. - A label inside the fuel flap often says which fuel goes where, on plenty of vehicles. Check for it. - The handbook says where it is if your filler is not next to the diesel cap: the boot, or under the bonnet. - Whoever had it before knows. Ask when you pick up a rental or fleet car — from Wymondham's car park, perhaps — rather than when the light appears. ## Keeping AdBlue out of your diesel tank when you top up Anywhere across Norfolk the light comes on, this is a routine for that day. - Pull in somewhere level, motor off, with time to spare — never rushing on the side of Cock Street. - Daft as it sounds, speaking "AdBlue" out loud as you unscrew the cap works — after you have found your filler and read it. - Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Stop once your tank is topped up or the bottle is empty; before that, pour gently using the built-in spout. - Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the car. Find during the second or third stage that AdBlue went into the diesel filler? That's where you stop. Skip step five entirely. ## Put AdBlue in the diesel tank around Barford already? The short order of things, starting with not starting your engine. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Do not top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is pulled from. Ask the staff to help push the car clear of the petrol pump if you're on a forecourt — the Sainsbury's, the Shell or anywhere else. At home in Barford? Then your car stays put. Already started? Stop once it is safe, then switch off. Come off the M11 — over 50 miles out of Barford — at the next junction. Distance counts — a short hop across Barford makes a smaller job than heading under 10 miles to Norwich — so tell us about how far it went. ## When we arrive around Barford, what occurs? By Barford Primary School, near Barford Village Sign or on your own driveway: wherever the car has stopped, we come to it. We ask what went in, about how much, and whether it has run, since the replies decide the work and our price. The quote is given on the call, before any van leaves. Next: a drain, then a thorough flush of the whole system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. We don't go until it has been started and is running smoothly. Most jobs are done in about half an hour once our engineers arrive, as long as the engine hasn't run — and the pumps our technicians use are safe on a busy forecourt and quiet after dark outside a house. No money in advance; you settle up that day. Afterwards, a VAT invoice and the report from the engineer go to you for the insurer. Before we get there, take a look at your insurance documents; plenty carry cover for misfuelling. ## About Barford Barford is a small village in Norfolk, situated on the River Yare, with a low elevation of around 28 metres.
