--- title: Lyngford: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/lyngford-somerset/ location: Lyngford county: Somerset latitude: 51.028000 longitude: -3.095380 service: AdBlue in a Diesel Tank updated: 2026-10-28 --- # Lyngford: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? Stop here a minute if the diesel tank already has AdBlue in it: ignition off, motor off, and phone 0333 366 0103. A drain and a thorough flush, carried out right where the vehicle stands around Lyngford, is usually what it needs when caught before your motor runs. If you are reading before it has happened, the remainder of this page is about why it takes place and how to make sure it doesn't. ## Two fillers, two tanks: AdBlue in a diesel motor Diesel goes to your motor — yet many current diesels driven about Lyngford and Firepool hold a second fluid as well. Kept in a tank of its own, AdBlue is fed into the exhaust stream and cleans it. Each tank has its own filler. Some cars keep the AdBlue filler in the boot or under the bonnet; a lot more place both side by side under one flap. At the petrol pump, your diesel side gets filled all the time. Far less regularly, the AdBlue side gets filled — mostly from a bottle, by someone thinking about where it goes. It is in that gap that the mistake lives. ## How AdBlue in your diesel tank takes place around Lyngford Rarely is it carelessness: normally three things line up. First, the warning. Low AdBlue triggers a warning from the vehicle, and running dry means limp mode — so a rushed top-up, perhaps before work off Grange Road, or at The Waggon on the way home that evening. The old car's cap is where your hand reaches — yet a rental car, a new motor or a company car keeps the fillers somewhere else. That's a second thing: a new car. Nothing stops the tip 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 a few seconds, whether in Obridge or right in the heart of Lyngford. ## Which filler is for AdBlue, and which for diesel? Whether a Lyngford forecourt or a drive over in Rowbarton, spend a couple of seconds on these before anything goes in. - Read the cap instead of going by position: AdBlue ones are commonly blue or marked "AdBlue", and diesel ones normally aren't. - Many vehicles fit AdBlue the smaller filler of the two. - A label inside your fuel flap often says which fuel goes where, on plenty of cars. Check for it. - The handbook. If the filler isn't by your diesel cap, it is in your boot or under the bonnet, and the handbook says which. - The previous driver knows. Ask when you collect a hire car or fleet car — at Taunton's car park, perhaps — rather than once the light appears. ## AdBlue top-ups that never reach the diesel tank The day the light goes on, anywhere in Somerset, use this routine. - Switch off after you park — level ground, engine stopped, and never rushed by Grange Drive on the verge. - Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud while you unscrew it. It sounds silly. It does the trick. - Both behind one flap? Then make sure the lid on the diesel filler is still closed ahead of lifting the bottle. - Slowly is best, through the bottle's own spout, till it is full or the bottle runs out. - Only then, start the car: close the cap, check again, and make sure the diesel cap was never opened. Stop there if you find, at stage two or three, that you have already poured into your diesel side. Leave out stage five entirely. ## Already put AdBlue in your diesel tank around Lyngford? The short order of things, beginning with not starting the motor. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel will not dilute it: rather than mixing, AdBlue sinks to the bottom of your tank, right where fuel is drawn from. At a forecourt — Asda Express, Morrisons or any other — the attendants will normally help push your car away, if you ask. Your own driveway around Lyngford is the place it stays. Already started? Pull over when it's safe, then switch off. The next exit is where to come off when you are on the M5, under 3 miles from Lyngford. Distance counts — a short hop across Lyngford makes a smaller job than heading under 25 miles towards Wells — so tell us about how far it went. ## Lyngford: what occurs when our engineers arrive We come to the car wherever it has stopped, whether that's outside Priorswood Primary School, near Wellesley Street Communal Hall or on your own drive. What liquid was put in, the quantity, and if it ran: our technicians ask because the replies set the work and price. On the phone call itself, you are told our price — ahead of dispatch. Next: draining, then a full flush of the whole system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. A test is at the end: before that, clean diesel goes in, and the filter is cleaned or replaced as needed. The motor is started next and tested to confirm it runs properly, all before our technicians go. If your motor has not run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. Your insurer usually wants an engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no money upfront. Wrong-fuel cover is included in many insurance policies — and so make use of the wait to look at yours. ## About Lyngford Lyngford is a suburban area in Somerset, situated near the River Tone and characterised by its semi-detached housing stock.
