Caught before your motor runs, it is generally a drain and a thorough flush, done where the vehicle is in Hallam Fields. The rest of this page explains why it takes place and how to ensure it doesn't — handy if you are reading ahead of time. ## AdBlue in a diesel motor: two tanks, two fillers Many modern diesels on the roads round Hallam Fields and Little Hallam carry two liquids, not one. Diesel goes to the engine. 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. Under one flap, side by side: that is the arrangement on a lot of vehicles. Elsewhere, AdBlue's filler sits beneath the bonnet or in your boot instead. The diesel side is fuelled at the pump all the time. The AdBlue side is fuelled far less regularly, normally from a bottle, and normally by a person who has to stop and think where it goes. That gap is where the mistake lives. ## AdBlue in your diesel tank around Hallam Fields: how it happens Seldom is it carelessness: normally three things line up. Hurry follows from the warning. Your car tells you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done in a rush, before work on a driveway off Merlin Way, or on the way home in the car park outside Festival Inn. Then the car is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand reaches for the cap it would have used on the old one. A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. So the tip, once started, keeps on. It takes seconds, whether out in Trowell or right in the heart of Hallam Fields. ## Telling the AdBlue filler from your diesel filler Before you pour anything, whether on a driveway in Stanton Gate or a forecourt in Hallam Fields, check these. They take a few seconds. - Where it sits misleads; the cap does not. AdBlue caps are often blue or carry the word "AdBlue" — diesel ones usually do not. - Look at the size: the smaller neck is, on plenty of vehicles, the AdBlue one. - A label inside the fuel flap frequently says which fuel goes where, on plenty of cars. Look for it. - The handbook says which it is when the filler isn't next to the diesel cap: your boot, or under the bonnet. - Collecting a hire or company car, say at the car park outside Ilkeston? Check with whoever drove the vehicle last before leaving, not once the light comes on. ## AdBlue top-ups that never reach your diesel tank When the light comes on, anywhere across Derbyshire, follow this routine. - Pull in on level, engine off, with time in hand — never rushing on the side of Hallam Fields Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the vehicle on. - Gently is best, through the bottle's own spout, till it is full or the bottle is empty. - Only then, start the car: close the cap, check once more, and make sure the diesel cap was never opened. Stop there if you find, at step two or three, that you've already poured into your diesel side. Don't go on to step five. ## Put AdBlue in your diesel tank in Hallam Fields already? Don't start your engine: that is how the short order of things begins. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with more diesel fails, because AdBlue sinks to the base rather than blending — and that is where the fuel is sucked from. At a forecourt — Asda, Morrisons or any other — the staff will normally help roll the vehicle away, when you ask. Your own driveway in Hallam Fields is the place it should stay. Where your motor has run by now, pull over safely and switch the vehicle off. On the M1, under a mile from Hallam Fields, that means the next exit. Tell us roughly how far it went: a run towards Nottingham, under 10 miles away, is a bigger job than a short hop across Hallam Fields. ## What takes place when our technicians arrive in Hallam Fields Anywhere your car has stopped, be it outside Trowell CofE Primary School, beside Wild Weeds Vetch or at home, our van comes to it. Both the work and the price depend on three replies — what fluid, what amount, and if it's run — so our engineers ask. You get that price on the phone, before anyone sets off. Next: draining, then a full flush of the whole system. Not like petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of that clears out by itself. That is why it matters more. After the fuel filter is flushed — or renewed, if required — clean diesel goes in, and finally your car is tested. Before we leave, we fire it up and check that it's running correctly. If your motor has not run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. The insurer usually wants the engineer's report and your VAT invoice, and both are yours at the end. Payment is on the day, with no deposit. Misfuelling cover is part of plenty of insurance policies — and so make use of the wait to check yours. ## About Hallam Fields itself Hallam Fields is a suburban area in Derbyshire, situated near the River Erewash and close to the city of Nottingham.
