--- title: Don't Start It: AdBlue in a Diesel Tank Cricket Hill canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/cricket-hill-hampshire/ location: Cricket Hill county: Hampshire latitude: 51.337610 longitude: -0.817060 service: AdBlue in a Diesel Tank updated: 2026-10-06 --- # AdBlue in the Diesel Tank in Cricket Hill? Keep It Switched Off With AdBlue in your diesel tank, the ignition remains off and so does your engine. AdBlue is urea dissolved in water. As it is water-based, it will not ignite and never combines with diesel; trouble just starts when the pump begins drawing it. A drain and a thorough flush, done where the car is in Cricket Hill, is usually all AdBlue in a diesel tank needs — if it's caught before the engine has been run. First, ring us on 0333 366 0103. ## AdBlue in your diesel tank in Cricket Hill: the first few minutes To do: - Keys out — that way nobody can switch anything on. - If you are anywhere near moving traffic, put the hazard lights on. - The empty bottle or the till receipt tells us the fluid and the quantity, so don't throw it away. - Tell us a postcode starting GU46 6, or whichever street lies nearest, and our van finds you directly — so ring from wherever you are. Do not do these: - Do not start the engine, even for a moment to move the car. - Don't switch the ignition on. On many diesels that alone runs the fuel pump. - Adding more diesel doesn't help: AdBlue settles out instead of thinning. - Never drive the vehicle anywhere, not even a short distance down Jenny's Walk. - By the road, don't try draining it on your own. The staff on duty at any Cricket Hill forecourt — the Esso included — will normally help pushing it clear if you ask. If you are on your own drive, leave it exactly where it sits. ## What AdBlue does in a diesel tank Made for the exhaust, AdBlue has no business in your motor. It goes into its own tank and is sprayed into your exhaust gas to clean it. Not one side fits the other: urea does not belong in a pump, and a pump can't take urea. It doesn't blend. Once it's poured into a tank of diesel, AdBlue acts nothing like diesel. It's heavier than diesel, and so it sinks and collects at the bottom of your tank, which is where the pickup sucks fuel from. When the pump runs, the AdBlue is top of the list to be pulled through. Before then it sits underneath your diesel, and that is why a vehicle filled in Frogmore yesterday and never switched on remains the simple one, provided no one touches the key. After it is pulled in, the harm takes two forms. What remains when the water goes is urea, which turns into crystals: they settle in tiny channels and block filters. Worse, it attacks certain metals in the fuel system, and keeps going till it is cleared out. Where the AdBlue has reached the pipework, leaving it till morning around Cricket Hill makes it worse. In the tank alone, waiting costs nothing. Diesel lubricates the injection pump and every injector as it flows; water gives none of that, which is a separate kind of harm. ## Why AdBlue in a diesel is frequently more serious than petrol Petrol pumped into a diesel on Texaco's forecourt makes the fuel thin — that is the whole issue. Harm just comes from driving on it. Blended into the diesel and sitting in that tank, it does nothing. With AdBlue in a diesel, the liquid itself is plainly the wrong one. Since it does not burn, running it through is not an option. Deposits and corrosion remain after the next fill, and AdBlue splits back from your diesel, so watering it won't help. That is why the flush matters so much, and turning the key "to see" costs more here than almost any other slip — in Little Sandhurst or the centre of Cricket Hill equally. The good news is the same as with petrol. Wherever across Hampshire your vehicle has come to rest, an unrun engine means the AdBlue still in the reservoir: the simplest part of any fuel system to clear. ## Cricket Hill: how AdBlue ends up in a diesel tank It's not on purpose. Many vehicles keep the AdBlue inlet beside the diesel one, now and then behind one flap, and muddling them up is easy after dark. It usually takes place at home, from a container bought on the journey home, rather than at the forecourt. Mostly, it takes place in one of a couple of familiar ways. Midway through the drop-off, the dashboard warns, and outside Cranford Park Church of England Primary School the top-up is hurried. Someone pours the container in at home, right off Cricket Hill Lane, as the day ends. Or the vehicle is topped up in the car park outside The Royal Oak, in poor light, by somebody who has never opened that flap before. It occurs most in the motors drivers 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 off: that is the first response to an identical slip, anywhere around Cricket Hill or the remainder of Hampshire you are. ## AdBlue in your diesel tank in Cricket Hill, and the motor started? In that case, the AdBlue is no longer inside your tank. It's been drawn through the filter and the lines, and if the engine ran for any time, it has got to your high-pressure pump and your injectors. Rough running, smoke, dropping power, dashboard warnings or stalling: each might show up, maybe midway across Cricket Hill or coming back from Church End Green. No restarting to check: pull over when it is safe, then turn everything off. More of it is pulled through with each start. Exit the M3, under 3 miles from Cricket Hill, by the next junction and stop safely, not carrying on. Every mile carries the AdBlue further in. That is why crossing Cricket Hill to park beside Yateley WI Hall and a drive of under 50 miles towards Winchester are very different jobs. Approximately how far had it come? Tell us. We do all of the rinsing where the car has stopped, and once the motor has been run there is more of it. Caught early, it very seldom leaves long-term damage. ## What clearing AdBlue from a diesel involves around Cricket Hill A street by Frogmore Leisure Centre, a drive, a lay-by or a filling station: wherever the car has come to rest in Cricket Hill, our engineers travel to it. What was put in, roughly how much, plus whether your engine has been run: our technicians check before all else, since those shape the job. On the spot, your tank is then emptied, and all of the contaminated diesel and the urea leave as one. What remains from AdBlue won't wash out unaided, and so the whole system gets a careful flush, which counts far more with urea than with petrol. Testing your vehicle comes last, after fresh diesel goes in and the filter is flushed or, if needed, replaced. If your motor has not run, most jobs take about half an hour once we are there. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house at night. Priming the system with clean diesel comes last. Firing it up comes next, and then you set off from where the vehicle is parked, at Sandhurst or on a driveway in Cricket Hill. The test before our technicians leave is that it runs properly on clean diesel. No garage is required at any point, with the whole job done then and there. Insurers ask for a VAT invoice and an engineer report, and you get both afterwards. ## About Cricket Hill, briefly Cricket Hill is a locality in Hampshire, situated on the riverside at an elevation of 62 metres, with semi-detached housing being the predominant type of accommodation. Cricket Hill lies near the towns of Yateley and Sandhurst, and is also close to Darby Green. Cricket Hill is located within the South East region, approximately 31.9 miles from London and 28.6 miles from the city of Winchester. ## AdBlue drains across Hampshire, Cricket Hill included AdBlue jobs in Cricket Hill go to vans that cover the places near it — Yateley, Darby Green as well as Sandhurst — and much of Hampshire beyond, across GU postcodes. Ring and ask rather than guess when you are by a border, or anywhere awkward to explain. Cricket Hill is a small village, and a call-out drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, we drain it where it is, so it never needs to be moved to us. ## What does AdBlue in a diesel tank cost to sort out around Cricket Hill? There is no fair single quote, because the jobs are not the same. Three things change the price: whether the engine has been running and for how long, how much AdBlue got in, and where the car is. That last one comes down to whether our van can reach it safely, and an open drive is simpler than a tight space behind Yateley Baptist Church. That's why every call from Cricket Hill starts with the same three questions, asked before giving a figure, not after: what went in, how much, and whether it has run. Their replies shrink a range down to one number. You get that price by phone, before anyone heads out, and you pay on the day, by card or over the phone, with nothing upfront. While our engineer is travelling, check your insurance: many include misfuelling. ## Still alongside your car in Cricket Hill? Then the most helpful thing you can do is nothing to the car. Keys out; motor and ignition off. Petrol in Diesel takes over the rest, across Cricket Hill or wherever in Hampshire, once you ring 0333 366 0103 saying it was AdBlue, roughly how big an amount, and whether it ran.
