A drain plus a full flush, done just where your vehicle stands around Titford, is usually what it needs when caught before your motor runs. Here in advance? In that case what follows explains why it comes about and what to prevent it ever happening. ## AdBlue in a diesel motor: two tanks, two fillers Diesel feeds your motor — yet many modern diesels seen around Titford and Langley Green carry another fluid too. Your exhaust, not your engine, is where AdBlue ends up: sprayed into the fumes to fresh them, from its own tank. There is a filler on each tank. Under one flap, side by side: that's the arrangement on many motors. Elsewhere, AdBlue's filler sits beneath the bonnet or in your boot instead. At the petrol pump, the diesel side gets filled constantly. Much less often, the AdBlue side gets topped up — normally from a bottle, by a person working out where it goes. That gap is where the slip lives. ## How AdBlue in your diesel tank takes place around Titford Three things tend to line up, and carelessness is rarely one of them. The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a drive off Swan Crescent before work, or in the car park at The Navigation on the way home. Then the vehicle is strange. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand reaches for the cap it would have used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour after it has started. It takes seconds, whether in Whiteheath Gate or right in the heart of Titford. ## How to tell the AdBlue filler from the diesel one Look at these before pouring, on a forecourt in Titford or a driveway over in Bristnall Fields. Seconds, no more. - Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually does not. Trust the cap, not its position. - Check the size: the smaller neck is, on plenty of cars, the AdBlue one. - Check inside your fuel flap: plenty of motors carry a label there saying which fuel goes where. - The handbook shows which it lives if the filler isn't next to your diesel cap: your boot, or under the bonnet. - Check with the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Rowley Regis. ## Topping up AdBlue without it reaching your diesel tank On the day the light appears — anywhere it is around West Midlands — a simple routine to follow. - Not in a rush on the side of Titford Road, not on a slope, not with your engine running: park then switch off properly. - Daft as it sounds, speaking "AdBlue" aloud as you unscrew the cap works — once you have found your filler and read the cap. - The two under one flap? So confirm the cap on the diesel filler is still closed before raising the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Only then, start your car: close the cap, check a second time, and make sure your diesel cap was never opened. If at step two or three you find you have already poured into the diesel side, stop there. Never go on to stage five. ## Already put AdBlue in your diesel tank around Titford? Short list, then. First: your engine stays unstarted. The fuel pump starts on plenty of diesels the moment your ignition goes on — so leave it off. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where the fuel is sucked from. On a forecourt — Asda, Texaco or another — the attendants will usually help roll the vehicle away, if you ask. If you are on your own drive around Titford, leave the vehicle where it is. Where your motor has been run already, stop safely then switch the vehicle off. Leave the M5 — under a mile out of Titford — at the first junction. Tell us about how far it went: a run towards Birmingham, under 10 miles away, is a bigger job than a short hop across Titford. ## When we turn up in Titford, what takes place? Anywhere your car came to rest, whether outside Causeway Green Primary School, near Rock Driller or on your own drive, the van travels to it. 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 price on the phone, before anybody heads out. Then your tank is drained and the system flushed thoroughly. Much more than with petrol, it matters with AdBlue: crystals build up, some metals corrode, and none of it clears out on its own, however long it is left. A test is at the end: before that, fresh diesel goes in, and the fuel filter is flushed or changed as needed. We don't leave until it has been fired up and is running properly. Using pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the motor has not run need about half an hour once our technicians arrive. Payment is on the day, not upfront, and you receive the documents your insurer asks for: an engineer's report and a VAT invoice. It is worth looking at your policy as the van travels to you: misfuelling cover is included with many policies. ## About Titford and where it is Titford is a suburban area located on the lakeside in the West Midlands, with an elevation of around 155 metres.
