--- title: Houghton-le-Spring: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/houghton-le-spring-tyne-and-wear/ location: Houghton-le-Spring county: Tyne and Wear latitude: 54.844050 longitude: -1.471600 service: AdBlue in a Diesel Tank updated: 2026-10-20 --- # Houghton-le-Spring: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It? If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and the ignition off then phone 0333 366 0103. Usually, when your engine hasn't run, it is emptied and thoroughly cleaned where the vehicle sits in Houghton-le-Spring. Here before the event? Then what follows covers how it comes about and how to prevent it happening at all. ## AdBlue in a diesel car: two tanks, two fillers No single liquid but two: that's what plenty of modern diesels around Houghton-le-Spring and Burnside carry, with diesel for your engine. The exhaust, not the motor, is where AdBlue goes: dosed into the fumes to clean them, from its own tank. There is a filler for every tank. Some vehicles keep the AdBlue filler in the boot or under the bonnet; plenty of others have the two together under one flap. Filling your diesel side at the petrol pump happens constantly. Much less often, the AdBlue side is filled — normally from a bottle, by a person working out where it goes. The mistake lives in that gap. ## Houghton-le-Spring: how AdBlue in the diesel tank happens Seldom is it carelessness: normally three things coincide. To start with, the warning. Low AdBlue triggers a message from your car, and running out means limp mode — hence a hurried top-up, perhaps before work off Mautland Street, or at The Britannia on the way home after work. Then your car is unfamiliar. 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. Nothing stops the tip once it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It takes a few seconds, be it out in New Town or right in the heart of Houghton-le-Spring. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a drive in High Dubmire or a forecourt around Houghton-le-Spring, check these. They take a few seconds. - Colour and marking: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not its position. - Look at the size: the smaller neck is, on many motors, 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 is in the boot or under the bonnet, and the handbook says which. - Ask 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 Chester-Le-Street. ## Topping up AdBlue without it reaching the diesel tank A routine for the day the light comes on, wherever in Tyne and Wear that is. - Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Wheler Street. - Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap works — once you've found the filler and read it. - The two under a single flap? So confirm the cap on your diesel side stays shut before lifting the bottle. - Slowly is best, through the bottle's own spout, till it's full or the bottle is empty. - Before starting your car, close the cap and look a second time that the diesel cap was never came off. If at stage two or three you find you have already poured into the diesel side, stop there. Stage five is out. ## Already put AdBlue in the diesel tank around Houghton-le-Spring? Don't start your engine: that is where the short order of things begins. 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 bottom rather than mixing — and that's where the fuel is pulled from. If you're at a forecourt, whether it's the Tesco or the JET, ask the attendants to help roll the car clear of the pump. Leave it where it is if you're on your own drive in Houghton-le-Spring. If the engine has already run, stop as soon as it is safe and switch off. Come off the A1(M) — under 3 miles out of Houghton-le-Spring — at the first junction. Mileage matters — a quick hop across Houghton-le-Spring is a smaller job than heading under 10 miles to Sunderland — so say roughly how far it went. ## When our technicians turn up around Houghton-le-Spring, what happens? We come to the vehicle wherever it has stopped, whether that's outside Bernard Gilpin Primary School, close to Houghton-le-Spring Methodist Church or on your own drive. Those answers settle the work and the price, so our engineers ask what got in, roughly how much, and if it has run. You hear that price by phone, before anybody heads out. After that: a drain, then a thorough flush of the whole system. Much more than with petrol, it matters with AdBlue: crystals build up, certain metals corrode, and nothing washes out unaided, no matter how long it is left. Testing is at the end: before that, clean diesel is added, and your filter is cleaned or changed if necessary. Next our technicians fire it up and check it runs smoothly before we go. Unstarted cars mostly need a half-hour job from the moment we arrive. The equipment is safe on a live filling station, and quiet enough for a residential street late at night. Your insurer will ask for an engineer's report and your VAT invoice, and you get both once the job is done. Payment comes on the day, with no deposit. Wrong-fuel cover is included in many insurance policies — so make use of the wait to look at yours. ## About Houghton-le-Spring itself Houghton-le-Spring is a town in Tyne and Wear, situated inland at an elevation of 64 metres, approximately 5 miles west of Sunderland.
