--- title: Don't Start It: AdBlue in a Diesel Tank Westrip canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/westrip-gloucestershire/ location: Westrip county: Gloucestershire latitude: 51.751740 longitude: -2.254390 service: AdBlue in a Diesel Tank updated: 2026-10-07 --- # Don't Start It: AdBlue in a Diesel Tank in Westrip Motor off, ignition off: that is where you start if AdBlue has got into your diesel tank. Urea mixed in water is all AdBlue is. The trouble begins once it is sucked through the pump — it will not burn, and it won't combine with diesel. In Westrip, AdBlue in a diesel tank found before the engine runs normally comes down to a drain and a thorough flush, right where the car is. First, call us on 0333 366 0103. ## What to do straight away, Westrip: AdBlue in your diesel tank Do these: - Pull the keys out, so nobody switches the ignition on. - Put your hazards on if you are at all close to moving traffic. - Hold on to the receipt or the empty bottle, so you can tell us what went in and about how much. - Give us a postcode starting GL6 6, or whichever street is nearest, and our van finds you straight — so call wherever you stand. Not to do: - Do not start your motor, even for a moment to move the vehicle. - Switching the key to ignition alone sets your pump running on many diesels. Skip it. - No more fuel on top. The AdBlue won't mix, so it is pointless. - Any driving at all is best avoided, including a short distance down Redhouse Lane. - Beside the road, do not attempt emptying it yourself. At a forecourt around Westrip, whether it's the Esso or another one, ask the attendants to help you push your car clear of the petrol pump. If you are on your own drive, leave the car precisely where it stands. ## AdBlue in a diesel tank, and what it does there Not the engine but the exhaust is where AdBlue is meant to go. Stored in a dedicated tank, it is squirted into the exhaust to clean the fumes. No part in an injection pump is made for this fluid — and none of that was intended to travel that way. It does not blend. After it is poured into a tank of diesel, AdBlue behaves not at all like diesel. Heavier than diesel, it drops and collects below it — the same spot the intake sucks from. A vehicle topped up on a driveway in Randwick overnight and left unstarted counts as the simple one. Nothing has pulled the AdBlue up so far — but when the motor turns, that's what is pulled first, straight from the bottom of that tank. It causes two kinds of damage from there. What remains once the water goes is urea, which forms crystals: they lodge in tiny channels and clog filters. Worse, it attacks some metals in a fuel system, and keeps going till it is flushed out. Lines holding AdBlue spell harm overnight for a car sitting in Westrip. Only inside your tank, it stays the same. And there is the water: it offers no protection to the components that rely on it the most — the high-pressure pump and each injector. ## Why is AdBlue in a diesel regularly the bigger fault? A fault of thin fuel is what you end up with after fuelling a diesel with petrol at the Texaco. It mixes with your diesel, and whilst it is inside that tank it does no harm; the harm comes from running your engine on it. AdBlue in a diesel is another matter: not thin fuel, but no fuel at all. It does not burn, so it cannot just be run through. Deposits and corrosion remain after the following fill, and AdBlue separates again out of the diesel, so watering it can't help. That is why the flush counts so much, and trying the engine "to see" costs more with AdBlue than almost any other slip — in Bread Street or the heart of Westrip alike. The good news is the same as with petrol. If your motor hasn't run, the AdBlue is still inside that tank, and that tank is the simplest part of a fuel system to clear, wherever across Gloucestershire your car is sitting. ## AdBlue in a diesel tank in Westrip: how it ends up there It's not deliberate. Plenty of cars have the AdBlue cap alongside the diesel one, occasionally under one flap, and muddling them up is simple after dark. A bottle bought when heading home and poured in at home, rather than at the forecourt, is the usual story. Mostly, it occurs in one of a couple of familiar ways. Hurrying, outside Cashes Green Primary School, after a warning light flashed on during the school run, someone tops up the car. In the evening, a container is tipped in on a driveway near Far Westrip. Or your car is topped up in the car park at Carpenters Arms, in poor light, by a person who has never opened that flap before. It happens most in the cars motorists know least: a hire car, a new motor, a company car, or the second motor of a household with one diesel and one petrol. Keep it switched off: that's the first response to the same mistake, anywhere in Westrip or the rest of Gloucestershire you are. ## AdBlue in your diesel tank in Westrip, and the motor started? In that case, the AdBlue is no longer in the tank. Through your filter, through the lines, and — with any running — into the injection pump and each injector: that's where it has gone. Expect rough running, exhaust smoke, lost power, warnings on the dash, or a stall — returning from Finns Way, say, or midway across Westrip. No starting it again to test: pull over once it is safe, then turn it off. Each start pulls more of that through. Leave the M5, under 3 miles from Westrip, at the next junction and park somewhere safe, not driving on. Every mile carries the AdBlue deeper into your system. That is why a hop across Westrip to park near Saint John and a drive of under 10 miles towards Gloucester are such different jobs. Tell us about how far it had come. Wherever your car came to a halt is where all of it gets done, even with more to clean out after your engine has been started. When it's noticed early, permanent damage is very rare. ## What does an AdBlue drain on a diesel involve in Westrip? The vehicle remains put, whether that is a street near Randwick Village Hall, a drive, a lay-by or a filling station around Westrip, and our van travels to it. What was put in, roughly the quantity, plus whether the motor has turned over: we ask before all else, since those decide the work. The contaminated diesel and the urea come out together when the tank is emptied, right there. With AdBlue, more so than with petrol, flushing counts: the whole system is cleaned all the way through because what remains won't flush away unaided. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Not run? Then count on roughly half an hour once we are there for most jobs. The pumping gear is explosion-proof, so a busy forecourt is no fault, and it's hushed enough for a residential street after dark. Bleeding the system with new diesel comes at the end. Starting the car comes next, and then you drive off from where the vehicle is parked, outside Stonehouse or on a driveway in Westrip. We check it runs correctly on new diesel before leaving. The entire job is done where the vehicle is, so it never needs to be taken to a workshop. The insurer will want an engineer's report and the VAT invoice — each handed over once this job is done. ## About Westrip Westrip is a suburban area in Gloucestershire, situated approximately 7.8 miles from Gloucester and 92.8 miles from London.

Westrip has a population of around 3119 people and is characterised by predominantly semi-detached housing. ## AdBlue drains across Gloucestershire, Westrip included Over the GL postcode area, the vans answering AdBlue call-outs around Westrip serve most of Gloucestershire too, Cashes Green, Hamwell Leaze and Puckshole included. Ring and ask instead of guessing when you are close to a county line, or anywhere tricky to pin down. Anywhere the car stands — your driveway at home, a residential street, a car park, a filling station — our engineers empty it on the spot, and there's no need to bring it to us; which suits Westrip, a residential suburb, well. ## What does AdBlue in a diesel tank cost to sort out in Westrip? No flat figure could be fair, since each job is different. What moves the cost is, first of all, whether the motor has run and for how long; then how much AdBlue was put in; and after that where the vehicle is and whether a technician can reach it safely, which is simpler on an open drive than in a tight space behind Cross Dyke. Ahead of a quote, never afterwards, every call from Westrip begins with the same three checks: the fuel, the quantity, and whether the engine ran. The replies turn a range into a straight quote. You hear that quote by phone, before anyone sets off, and you pay on the day, by card or by phone, with nothing upfront. Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van arrives. ## Still beside the vehicle in Westrip? Right now, the most helpful thing to do with your car is to leave it. Engine off, keys out, ignition off. Say it was AdBlue, roughly how big an amount, and whether it ran, on 0333 366 0103. From there Petrol in Diesel takes over, across Westrip or wherever in Gloucestershire.
