--- title: Littledean: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/littledean-gloucestershire/ location: Littledean county: Gloucestershire latitude: 51.819110 longitude: -2.480800 service: AdBlue in a Diesel Tank updated: 2026-10-22 --- # Littledean: AdBlue in the Diesel Tank? Find Your Situation What to do about AdBlue in a diesel tank depends on one thing more than any other: whether the engine has run since it went in. Anywhere the vehicle is — Mount Pleasant, Littledean — never start a motor that hasn't been started yet. Leave the engine and the ignition off and phone 0333 366 0103; it's normally a drain and a thorough flush, done where your car is around Littledean. Already started? Pull over once you safely can, then turn it off. The job is bigger, but the first step is the same. Find the situation below that matches yours, wherever in Gloucestershire it happened. ## Littledean forecourt: AdBlue in a diesel at the pump Just now, nozzle still in hand, you realise that the cap you took off was the wrong one, there at the petrol pump. Be it EG on the move, Shire Fuels or somewhere else around Littledean, the situation is the same. Meaning? Spotting it here is as good as it gets. Only your tank holds AdBlue; no component beyond it has taken it in. Next: resist the urge to fire it up just to free up the petrol pump. Ask the attendants to help you push the car into a parking spot, keep your receipt or the bottle, and ring us from the forecourt. Draining it right at the pump is fine if it can't be shifted, since the equipment is explosion-proof. ## At home around Littledean with AdBlue in the diesel tank Days had passed with the dash light on. Picked up a bottle, tipped it in at home, binned the empty — and only then looked at the cap again, too late. Houses just off Broad Street are hit as often as anywhere else. What it means: if you haven't driven since, this is almost as good as the forecourt. Diesel and AdBlue stay separate: the AdBlue drops to the floor of your tank and remains there, no matter how long it waits. Next: prevent any early move by keeping your keys indoors, then phone us. Out in Double View or here in Littledean, the drain happens at your drive. The pumps are quiet enough to use outside a house after dark. ## Drove off with AdBlue in a diesel in Littledean? Filled up, pulled away, and before long your motor was turning unevenly, blowing smoke, losing power, or flashing up the dash. Maybe heading to Gloucester, under 15 miles away, or simply along Folders Lane. The point: your system has drawn AdBlue through already. Distance sets how deep it goes: filter and pipework to begin with, then the injection pump and every injector. More driving, more restarts: deeper it goes. Stop somewhere safe — that is the next step — then switch everything off. Services farther on are too far: on the M50, under 10 miles out of Littledean, take the first junction. Don't restart the car to see if it has cleared; it will not have. Let us know the mileage covered when you ring. ## AdBlue in the wrong tank of a hire, lease or company car You have just had the vehicle a week. Your own vehicle either has no AdBlue or puts it somewhere different, and so no one told you the AdBlue cap was just next to the diesel. Anywhere you happen to be in Gloucestershire, every driver could be caught. Meaning? Whichever applies above counts too — run or not — and one extra step. The owner frequently needs to approve the work, under many hire and company contracts. Settling it before the van turn up is faster, and so phone the rental company or your fleet manager, and then us. Stranded near Littledean War Memorial or at Lydney till someone replies, the car stays turned off throughout. ## Littledean: unsure if it was AdBlue in the diesel tank? Now and then, "I think so" is the most you can truthfully say. The bottle is lighter than it should be, there is a faint smell of ammonia around the filler, and you cannot remember which cap you took off. A rushed top-up by the gates of Littledean Church of England Primary School, or a visit to a friend in Cinderford: either fit. What it means: a little spilled around your filler does no harm to the engine. AdBlue inside the diesel tank does. You cannot tell which by turning the ignition, and doing so will suck in any AdBlue that is in your tank. Take it that it was put in, and never turn the key. Tell us what you saw on the phone. A clean tank checked counts as a happier outcome than an already-run one drained. ## Every AdBlue drain around Littledean shares these stages Whatever the case, a single opening applies. Three questions are asked when our engineers reach your car — at a filling station, a driveway, a road by Miners' Memorial or the car park outside The Belfry: the fluid, the quantity, and if it has run. Your price comes on the call, before a van leaves, and those answers shape the work. AdBlue crystallises and eats at some metals used in fuel systems, so it does not rinse out unaided; that's why the flush, after the drain, counts much more here than with petrol. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Most unrun vehicles are a half-hour visit after the moment we arrive. Our technicians fire it up at the end. Before we go, it's tested to confirm it runs properly on clean diesel. The entire job is done where your car is, and when it's caught soon, permanent damage is very unusual. For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, nothing in advance. Worth knowing: lots of insurers offer misfuelling cover, and so a quick look at your documents as we travel pays. ## About Littledean, for a moment Littledean is a village in Gloucestershire, situated inland at an elevation of 151 metres, approximately 10.5 miles from Gloucester.
