In that case put this page down a moment, keep the ignition and motor off, then phone 0333 366 0103. Caught before your engine runs, it is normally a drain and a thorough flush, done where the car is in Wrington. Reading before the event? In that case what follows covers why it happens and how to stop it ever happening. ## AdBlue in a diesel motor: two tanks, two fillers Diesel feeds your motor — yet many newer diesels driven around Wrington and Udley carry a second fluid too. Stored in a tank of its own, AdBlue is fed into the exhaust gas to clean it. Different tanks, separate fillers. Some cars keep the AdBlue filler in the boot or under the bonnet; plenty of others have the two side by side under one flap. Filling your diesel side at the petrol pump goes on all the time. A driver who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and far less regularly. That gap is where the error lives. ## How AdBlue in your diesel tank occurs around Wrington Carelessness seldom causes it. What does is three things lining up together. On a drive off Broad Street before work, or in the car park outside The Golden Lion on the way home: that is where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low your car tells you, and if it is empty, limp mode kicks in. The old car's filler is where your hand goes — but a rental car, a new vehicle or a company car keeps the fillers elsewhere. That's the second factor: a new car. Nothing stops the pour once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Maines Batch or the heart of Wrington: it takes the same few seconds in both. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a driveway in Iwood or a forecourt in Wrington, check these. They take a couple of seconds. - Where it sits can mislead; the cap does not. AdBlue caps are often blue or carry the name "AdBlue" — diesel ones normally do not. - Plenty of motors give AdBlue the smaller filler of the two. - Look inside the fuel flap: plenty of motors carry a label there saying which fuel goes where. - The handbook shows where it is when the filler is not next to your diesel cap: your boot, or under the bonnet. - The previous driver knows. Check as you collect a rental or fleet car — from Yatton's car park, say — not once the warning comes on. ## How to top up without AdBlue in the diesel tank For the day the light appears — anywhere it is around Somerset — a simple routine to use. - Stop on level, motor off, with time in hand — not hurried on the side of Silver Street. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and 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. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Before starting your car, close the cap and look a second time that the diesel cap never came off. Discover at the second or third stage that AdBlue went in the wrong tank? That is where you stop. Don't go on to stage five. ## Already put AdBlue in your diesel tank in Wrington? Brief order, then. Top of that: the engine remains unstarted. Leave the ignition off as well, since on many diesels switching it on by itself starts your fuel pump. Do not top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where your fuel is drawn from. The attendants at Esso, Murco or any forecourt will normally help to push the car clear when you ask. Leave it where it is if you're on your own driveway in Wrington. If your engine has already run, stop as soon as it is safe and switch off. Leave the M5 — under 5 miles out of Wrington — at the first exit. A short hop across Wrington is a smaller job than a run towards Bristol, under 10 miles away, so tell us roughly how far it went. ## Wrington: what occurs when we arrive Anywhere your car came to rest, whether by Wrington Church of England Primary School, beside Memorial Hall or at home, our van travels to it. Both the work and our quote depend on three replies — which liquid, which amount, and if it's run — so we ask. During the phone call itself, you hear our price — ahead of dispatch. The system is then purged thoroughly, once the tank is cleared. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why the flush counts more with AdBlue than with petrol. Once the fuel filter has been flushed — or replaced, where needed — clean diesel is added, and then your car is tested. Before we leave, our engineers fire it up and check that it is running smoothly. Using pumps fine on a working forecourt and quiet enough to use outside a house at night, most jobs in which your engine hasn't run need about half an hour after our technicians are there. Paying happens on the day, not upfront, and you receive the documents your insurer asks for: an engineer's report and a VAT invoice. Misfuelling cover is part of many insurance policies — so make use of the wait to look at yours. ## About Wrington itself Wrington is a village in Somerset, situated on the banks of a river at an elevation of around 24 metres. Wrington lies approximately 9 miles from Bristol and 114 miles from London, making it a commuter village with easy access to the city.

A postcode starting BS40 5 gets our van to you fastest. There's no need to move your car. Our technicians drain it where it is — a side street close to Church of All Saints, a lay-by on the way to Wrington Tennis Club, a driveway. If you are near a border, or somewhere hard to describe like the back of Wrington Chapel (URC), ring and ask instead of guessing. ## In short, for Wrington people Read the cap before you tip. Petrol in Diesel drains it on the spot, anywhere across Somerset, if AdBlue has gone in the diesel tank anyway — so leave the car off and call 0333 366 0103.
