Normally, if the motor hasn't run, it is drained and thoroughly cleaned where the vehicle sits around Galmington. Nothing happened yet? Below, the rest of the page explains the why it occurs and the how to avoid it for good. ## AdBlue in a diesel car: two tanks, two fillers Not one fluid but two: that's what plenty of modern diesels around Galmington and Wilton carry, with diesel feeding your motor. Stored in a tank of its own, AdBlue is fed into your exhaust gas and cleans it. Every tank has one filler of its own. Plenty of vehicles share a single flap for the two, whereas others put the AdBlue filler to your boot or under the bonnet. Topping up the diesel side at the petrol pump happens constantly. Much less commonly, the AdBlue side is topped up — mostly from a bottle, by someone thinking about where it goes. It is in the gap that the mistake lives. ## AdBlue in your diesel tank around Galmington: how it takes place Three things tend to line up, and carelessness is seldom one of them. On a drive off Ramshorn Close before work, or in the car park outside The Shephards Rest heading home: that is where the hurried top-up takes place. What is the reason for the rush? As AdBlue runs low your car warns you, and if it is empty, limp mode follows. Unfamiliar vehicles are second, too. Rentals, new vehicles and company vehicles place their fillers differently, and the hand goes for the cap used on the old one. Nothing halts the pour after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It's seconds, be it in Haines Hill or right in the centre of Galmington. ## How to tell the AdBlue filler from the diesel one Look at these before pouring, at a forecourt around Galmington or a driveway out in Tangier. Seconds, that's all. - Colour and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not its position. - Look at the size: the smaller neck is, on many cars, the AdBlue one. - Look inside your fuel flap: many vehicles have a label there saying which fuel goes where. - The handbook. If your filler is not by your diesel cap, it's in your 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 collect a hire or company car from somewhere like the car park at Taunton. ## How to top up without AdBlue in the diesel tank Anywhere in Somerset the light comes on, here is a routine for the day. - Stop somewhere level, motor off, with time to spare — not rushing on the side of Ashford Road. - Find the AdBlue filler, read the cap, and say the name "AdBlue" out loud as you unscrew it. It sounds silly. It does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the car on. - Slowly is best, through the bottle's own spout, till it is full or the bottle is empty. - Before starting your car, shut the cap and check a second time that your diesel cap never opened off. Find at the second or third stage that the bottle went in the wrong filler? That's where you stop. Never go on to step five. ## AdBlue in the diesel tank already, around Galmington? What follows is a short order of things, starting with no starting the motor. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Thinning it with more diesel won't work, because AdBlue sinks to the base rather than mixing — and that's where your fuel is drawn from. On a forecourt — Esso, Texaco or any other — the attendants will usually help roll your car away, if you ask. On your own drive around Galmington? So the vehicle remains where it is. When the motor has been run by now, stop somewhere safe and switch the vehicle off. Leave the M5 — under 3 miles out of Galmington — at the first exit. Tell us about how far it went: a run towards Wells, under 25 miles away, is a bigger job than a short hop across Galmington. ## When we get there around Galmington, what happens? Our van comes to the vehicle anywhere it has come to rest — your own driveway, beside St Michael the Archangel Church, or outside Bishop Henderson Church of England Primary School, Taunton. Both the work and the price rest on three replies — which fluid, what amount, and whether it's run — so we ask. You hear that quote by phone, before anybody heads out. The system is then rinsed thoroughly, after that tank is drained. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that matters more with AdBlue than with petrol. Once the filter is flushed — or renewed, where required — fresh diesel goes in, and finally the vehicle gets tested. Before we leave, we fire it up and check that it is running correctly. Unstarted cars mostly mean a half-hour job after arrival. The equipment is safe on a live forecourt, and hushed enough for a driveway after dark. The insurer will ask for the engineer's report and your VAT invoice, and you get both once the job is done. Payment comes on the day, with no deposit. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way. ## About Galmington itself Galmington is a suburban area situated on the riverside in Somerset, with an elevation of around 24 metres.
