--- title: AdBlue in a Diesel Tank Barrow upon Soar — Don't Start It canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/barrow-upon-soar-leicestershire/ location: Barrow upon Soar county: Leicestershire latitude: 52.752400 longitude: -1.148800 service: AdBlue in a Diesel Tank updated: 2026-10-02 --- # AdBlue in a Diesel Tank in Barrow upon Soar? Don't Start It Motor off, ignition off: that's how you begin if AdBlue has got into your diesel tank. Urea dissolved in water is what AdBlue is. As it is water-based, it won't ignite and won't blend with diesel; trouble just comes once your pump begins pulling it. Caught before your motor has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the vehicle is in Barrow upon Soar. Before anything, call us on 0333 366 0103. ## What to do right now, Barrow upon Soar: AdBlue in your diesel tank Do: - So nobody can turn your ignition on, pull your keys out. - Put your hazards on if you are anywhere near moving traffic. - So you can give us which fluid it was and roughly how much, save your receipt or the empty bottle. - Our van finds you fastest with a postcode starting LE12 8, or simply the name of a street close by, and so call from the car. Do not: - No starting your engine — not for a second, not to reposition the vehicle. - Your ignition remains off: on many diesels, switching it on is enough to run the fuel pump. - Pouring in extra diesel doesn't work: AdBlue settles out rather than thinning. - Any driving at all is to be avoided, including a short stretch up Cotes Road. - No draining it yourself, either, on the verge. On a forecourt around Barrow upon Soar, whether it is the Pillings Lock Marina or another one, ask the staff to help you push the car clear of the pump. If you're on your own drive, leave the car exactly where it stands. ## What AdBlue does in a diesel tank Not the engine but your exhaust is where AdBlue is meant to go. Its own reservoir holds it, and from there it's fed into the exhaust, and there it treats the fumes. Neither side fits the other: urea does not belong in an injection pump, and a pump cannot deal with urea. Fuel blends; AdBlue, after poured in, won't. Its behaviour is not at all like diesel's. Heavier than diesel, it sinks and pools underneath it — the same place the pickup draws from. A vehicle filled on a driveway in Woodthorpe yesterday evening and not started since counts as the straightforward one. No pump has sucked the AdBlue up so far — though when your motor runs, that is what goes first, directly from the bottom of the tank. Two kinds of damage come from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, so it keeps labouring on the components it gets to for as long as it remains there. If the AdBlue is in the pipework, waiting till morning in Barrow upon Soar leaves things worse. Inside that tank only, waiting does nothing. The water in it does damage of its own: the high-pressure fuel pump and your injectors rely on diesel to lubricate them, and water offers them nothing. ## AdBlue in a diesel: why it is commonly worse than petrol Fill a diesel with petrol in error at the BP, and this issue is diluted fuel. No harm is done while it sits unused, mixed into the diesel — only when your motor works on it. AdBlue in a diesel is another problem: not thin fuel, but no fuel at all. It can't just be run through, since it doesn't burn. Crystals and corrosion remain after the next tankful, and AdBlue separates again from the diesel, so watering it can't help. Hence the flush matters more, and trying your engine "to see" does more harm here than nearly any other slip — in Cotes or the centre of Barrow upon Soar alike. The good news is the same as with petrol. Never run? Then the AdBlue sits just inside that tank, the easiest section of the whole system to empty, anywhere your car has come to rest around Leicestershire. ## Barrow upon Soar: how AdBlue ends up in a diesel tank In dim light, two caps together — the AdBlue one and the diesel one, occasionally behind one flap — may appear the same. No one means it; many designs invite it. Mostly it's never the filling station: a driver buys a container driving home and tips it in at home. It tends to occur in a couple of familiar ways. A warning light comes on during the school run, and the top-up happens in a hurry outside Barrow Hall Orchard Church of England Primary School. Close to North Street, someone tips a bottle in at home in the evening. Otherwise, in dim light outside The Three Crowns, the vehicle is refilled by a driver opening that flap the first time. It comes up most in a hire car, a new motor, a company vehicle, or the spare vehicle in a home with one of each fuels — the cars people know the least. Same mistake, an identical first step — keep it switched off — anywhere you happen to be around Barrow upon Soar or the remainder of Leicestershire. ## Started your engine with AdBlue in your diesel tank in Barrow upon Soar? The AdBlue has left that tank, then. It has been drawn through the filter and the lines, and if the engine ran for any time, it has reached your high-pressure pump and the fuel injectors. You may notice the engine running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Jerusalem Island or halfway across Barrow upon Soar. When you safely can, stop then turn everything off — without turning it on again to see. More of it is pulled through with each start. Exit the M1, under 10 miles from Barrow upon Soar, at the next junction and park safely, not driving on. Distance matters: every mile carries the AdBlue deeper in, and so driving towards Leicester, under 10 miles away, makes a much larger job than hopping across Barrow upon Soar to the car park by Holy Trinity. Approximately how far had it come? Tell us. Wherever your car came to a stop is where all of it gets done, even with more to rinse out once your engine has been running. Very seldom does it leave lasting damage if it's noticed soon. ## Clearing AdBlue in a diesel in Barrow upon Soar: what it takes A street beside Barrow upon Soar Parish Council, a drive, a lay-by or a filling station: anywhere your car has come to rest in Barrow upon Soar, our engineers come to it. The work rests on three answers, and our engineers get first — which fluid got in, the quantity, and if your engine has turned over. The polluted diesel and the urea leave as one when your tank is drained, right there. With AdBlue, more so than with petrol, flushing matters: the fuel system is flushed right through since residue won't flush away unaided. A test of the vehicle follows last, once clean diesel is added and the fuel filter is flushed or, if necessary, swapped. About half an hour once we arrive is typical for most jobs when the motor has not run. Our equipment is explosion-proof, and so a busy filling station is no issue, and it's quiet enough for a residential street late at night. New diesel goes in to prime your system, and that's the final step. Whether it is a parking space at the nearest station or a drive in Barrow upon Soar, that is where our technicians start it and you head off. Before leaving, our engineers make sure it is running smoothly with clean diesel in. No garage is required at any stage, with the whole job done on the spot. The insurer is likely to want an engineer's report and the VAT invoice — both yours afterwards. ## About Barrow upon Soar Barrow upon Soar is a village situated on the River Soar in Leicestershire, with a population of around 2400 people.
