Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/addiewell-west-lothian/ location: Addiewell county: West Lothian latitude: 55.847460 longitude: -3.608350 service: AdBlue in a Diesel Tank updated: 2026-10-03 --- # AdBlue in a Diesel Tank in Addiewell: Why It Occurs and How to Avoid It Keep the engine and ignition off and ring 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank. In Addiewell, catching it before your motor runs normally leaves draining and a full flush on the spot. The remainder of this page explains why it occurs and how to ensure it does not — useful if you are reading ahead of time. ## Two fillers, two tanks: AdBlue in a diesel car Not one liquid but two: that's how plenty of newer diesels around Addiewell and Stoneyburn carry, with diesel for your motor. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Different tanks, separate fillers. Other vehicles keep the AdBlue filler in your boot or under the bonnet; a lot of others have the two side by side under one flap. Diesel gets filled on each filling station call-out, again and again. Rarely filled, AdBlue normally goes in out of a bottle, tipped by someone who has to stop and think which filler it needs. That gap is where the mistake lives. ## How AdBlue in your diesel tank takes place around Addiewell It is seldom carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Faraday Place before work, or in the car park outside the pub in the village on the way home. Then the 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 gets to for the cap it would have used on the old one. A spouted bottle finds no obstacle at a diesel filler no more than at an AdBlue one. So the pour, after begun, keeps on. It takes seconds, be it in Addiebrownhill or right in the heart of Addiewell. ## Telling the AdBlue filler from your diesel filler Be it a Addiewell forecourt or a driveway out in West Mains Crofts, spend a couple of seconds over these before any is poured in. - Position misleads; the cap doesn't. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel ones usually don't. - Look at the size: the smaller filler neck is, on plenty of motors, the AdBlue one. - Look inside the fuel flap: many vehicles have a label there showing which fuel goes where. - In your boot or under the bonnet: that's where the filler is if it is not by your diesel cap, and the handbook says which. - The person who drove it last. On a hire or company car collected from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on. ## How to top up without AdBlue in your diesel tank On the day the light comes on — anywhere it is across West Lothian — a routine to use. - Pull in somewhere level, engine off, with time to spare — not hurried on the side of Station Court. - Find the AdBlue filler, read the cap, and say the word "AdBlue" out loud while unscrewing it. It seems silly. It does the trick. - Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Close the cap, and look again — confirm your diesel filler stayed closed throughout. Only then, start the car. Discover during the second or third step that AdBlue went in the diesel tank? That's where you stop. Never go on to stage five. ## Addiewell: already put AdBlue in the diesel tank? Then the order of things is short. Do not start the engine. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is drawn from — so do not top up with diesel to thin it. The attendants at BP, Tesco or any forecourt will normally help to push your car away when asked. At home in Addiewell? So the car remains put. Already started? Stop when it's sensible, then switch off. Addiewell sits under 3 miles from the M8; there, use the first exit. Mileage matters — a short hop across Addiewell is a smaller job than driving under 25 miles towards Dunfermline — so say roughly how far it went. ## What happens when our technicians turn up in Addiewell The van comes to your car wherever it stopped — your own drive, beside St Thomas the Apostle (Addiewell), or by the local primary school. Both the work and the price depend on three answers — what liquid, what quantity, and if it's run — so we ask. You hear that price by phone, before anyone heads out. Then that tank is cleared and the fuel system flushed thoroughly. 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 matters more here than with petrol. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Before we go, we fire it up and check that it is running properly. If the engine 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 after dark. Payment happens on the day, not upfront, and you receive the documents your insurer asks for: an engineer's report and a VAT invoice. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way. ## About Addiewell itself Addiewell is a village situated on the riverside in West Lothian, with a mix of detached housing and a population of around 725 residents.
