Leave your engine and ignition off then phone 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank. Caught before the motor runs, it is normally a drain and a thorough flush, done where the car is around Littleworth. The rest of this page covers why it occurs and how to make sure it does not — handy if you are reading ahead of time. ## AdBlue in a diesel car: two tanks, two fillers Diesel feeds your motor — but plenty of current diesels seen about Littleworth and Aston Subedge hold a second liquid too. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Each tank has its own filler. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. At the petrol pump, the diesel side gets filled all the time. Someone who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and much less often. That gap is where the mistake lives. ## AdBlue in your diesel tank around Littleworth: how it happens Three things tend to come together, and carelessness is rarely one of them. First, the warning. Low AdBlue brings a warning from your car, and letting it run out leads to limp mode — hence a rushed top-up, maybe before work off Park Road, or at The Volunteer Inn on the way home after work. The old car's cap is where the hand goes — but a rental car, a new motor or a company car puts the fillers somewhere else. That is the second thing: a strange motor. 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. Westington or the heart of Littleworth: it is the same few seconds either way. ## Telling the AdBlue filler from the diesel filler Whether a Littleworth forecourt or a driveway over in Weston-sub-Edge, take a couple of seconds on these before any goes in. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it instead of going by where it sits. - The size. On many motors the AdBlue filler neck is the smaller of the two. - The flap. Look inside the fuel flap for a label. Plenty of motors say there which fuel goes where. - The handbook. If the filler is not by your diesel cap, it's in the boot or under the bonnet, and the handbook says which. - The previous driver knows. Check when you pick up a hire car or company car — from Honeybourne's car park, say — rather than when the light comes on. ## AdBlue top-ups that never reach your diesel tank For the day the warning comes on — anywhere it is around Gloucestershire — a simple routine to use. - Turn off once parked — level ground, motor stopped, and not rushed beside Coronation Close at the roadside. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Silly, perhaps, yet it does the trick. - Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Slowly does it, through the bottle's own spout, till it is full or the bottle is empty. - Before starting your car, shut the cap and check again that the diesel cap never came off. Find at stage two or three that it's already gone into your diesel side? So stop just there. Don't go on to step five. ## Put AdBlue in your diesel tank in Littleworth already? Brief order, then. Top of it: your motor stays off. The fuel pump starts on many diesels the moment the ignition is switched on — so keep it off. Thinning it with more diesel won't work, because AdBlue settles to the base instead of blending — and that's where your fuel is drawn from. The attendants at Willersey Garage, Texaco or another forecourt will normally lend a hand to push the car away if you ask. At home around Littleworth? So the vehicle stays put. When your engine has been run already, pull over somewhere safe then switch the vehicle off. On the M5, under 15 miles from Littleworth, that means the next junction. Distance counts — a quick hop across Littleworth is a smaller job than heading under 25 miles towards Worcester — so tell us about how far it went. ## What occurs when our technicians turn up around Littleworth By St Catharine's Catholic Primary School, near St Catharines or on your own driveway: wherever the car has stopped, we come to it. Our engineers ask what got in, roughly how much, and whether it's run, since the answers decide the work and our quote. On the phone call itself, you hear the price — before anything else. Next: draining, then a thorough flush of the whole system. More than with petrol, it matters here: the crystals form, certain metals corrode, and nothing washes away unaided, however long it sits. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Before we go, our technicians fire it up and confirm that it's running smoothly. Using pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs in which your motor has not run take about half an hour after our engineers arrive. No money upfront; you settle up that day. At the end, a VAT invoice and a report from the engineer go to you for the insurer. While we travel, take a look at your insurance documents; plenty include cover for misfuelling. ## About Littleworth and where it is Littleworth is a suburban area in Gloucestershire, situated on the riverside at an elevation of around 145 metres.
