--- title: Don't Start It: AdBlue in a Diesel Tank Lambs Green canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/lambs-green-dorset/ location: Lambs Green county: Dorset latitude: 50.787740 longitude: -2.007640 service: AdBlue in a Diesel Tank updated: 2026-10-22 --- # AdBlue in the Diesel Tank in Lambs Green? Keep It Switched Off With AdBlue in your diesel tank, your ignition remains off and so does your engine. AdBlue is urea mixed in water. It doesn't burn, it doesn't mix with diesel, and the damage it does begins when the fuel system draws it in. A drain and a thorough flush, done where the car is in Lambs Green, is normally what AdBlue in a diesel tank needs — if it's caught before the engine has been run. Nothing comes before calling 0333 366 0103. ## Lambs Green, AdBlue in your diesel tank: what to do at once Do: - So no one can switch your ignition on, pull the keys away. - If you're anywhere near moving traffic, put the hazards on. - Which product, and roughly what volume? Hang on to the bottle or the till receipt, and we can know. - Ring us from where you are. A postcode starting BH21 3, or the name of the closest street, brings the van to you without a search. Do not: - Moving the vehicle just a few yards is no reason to start the motor. - Your ignition remains off: on many diesels, switching it on is enough to run the fuel pump. - Do not top up with diesel to thin it. AdBlue doesn't mix in diesel; it separates out. - Keep the vehicle where it is instead of driving it anywhere, even a short stretch along Lambs Green Lane. - Do not try to drain it yourself at the kerbside. The staff working at any Lambs Green forecourt — the Esso among them — will normally lend a hand rolling it clear if you ask. If you are on your own drive, leave the car exactly where it is. ## What AdBlue does in a diesel tank Made for the exhaust, AdBlue has no place in the engine. Stored in a separate tank, it is squirted into the exhaust to clean the fumes. A fuel pump isn't designed to cope with it, and AdBlue was never supposed to travel through one. Tipped in with your diesel, it keeps apart instead of blending — quite unlike fuel. The intake takes fuel from the lowest part of that tank, and that is exactly where AdBlue settles: being denser than diesel, it sinks. Once the pump runs, the AdBlue is top of the list to go through. Before then it sits underneath the diesel, and that is how a vehicle filled in Rushcombe Bottom yesterday and not started remains the straightforward case, as long as no one touches the key. From there it causes two kinds of harm. Crystals and corrosion. As the water dries, it leaves urea that crystallises in filters and narrow passages; and, since it eats at certain metals, each part it reaches keeps suffering for as long as it stays in there. If the AdBlue is in the lines, waiting till morning in Lambs Green makes things worse. In your tank only, waiting does nothing. And there's the water: it brings no lubrication to the components that need it the most — the high-pressure pump and each injector. ## Petrol or AdBlue in a diesel: why AdBlue is frequently worse A problem of thin fuel is what you end up with after filling a diesel with petrol at the BP. It mixes with your diesel, and whilst it's in that tank it causes no damage; the damage comes from running your motor on it. With AdBlue in a diesel, the liquid itself is simply the wrong one. It doesn't burn, and so it can't just be run through. Nor can it be thinned, because it splits back out — and the next tankful won't rinse away crystals or corrosion. So the flush matters more here, and turning the key "to see", in the centre of Lambs Green or out in Sleight, costs more than nearly any other slip. The good news is the same as with petrol. Never run? Then the AdBlue waits just inside the tank, the simplest section of the entire system to clear, anywhere your car has stopped around Dorset. ## Lambs Green: how AdBlue ends up in a diesel tank It is not on purpose. Plenty of cars keep the AdBlue inlet beside the diesel one, now and then behind a single flap, and mixing them up is simple in poor light. Mostly it is never the forecourt: someone picks up a container heading home and pours it in at home. The ways it occurs are few and familiar. The top-up gets hurried outside Pamphill Church of England First School, after the dash lit up with a warning as the children were dropped off. A bottle is poured in at the end of the day on a drive just off Candys Close. Or someone new to that flap refills your vehicle in dim light, stopped in the car park by Lambs' Green Inn. The least known cars get it most — hire cars, new ones, company ones, and the other motor of a home with one of each fuels. Keep it off: that is the first response to an identical slip, wherever around Lambs Green or the remainder of Dorset you happen to be. ## AdBlue in the diesel tank in Lambs Green, and the engine started? Then the AdBlue has left the tank. Given any running time, it travels to the injection pump and every injector, after passing via the filter and lines. Maybe coming back from Happy Bottom Nature Reseve, or part way across Lambs Green, your engine might go lumpy, smoke, lose power, flash your dash or stall. Stop when safe. Turn off. Leave the vehicle off rather than testing it again. Each start pulls more of it through. Lambs Green sits under 25 miles from the M27; if you were on it, exit at the next junction and stop safely rather than driving on. Distance matters: every mile pushes the AdBlue further into your system, so heading for Salisbury, under 25 miles away, gives a far bigger job than hopping across Lambs Green to the car park by Lake Farm Roman fort. Tell us about how far it had come. Once the motor has been started, the flush covers more, and all of it is done where the car has come to a stop. Noticed early, it very rarely leaves permanent damage. ## Clearing AdBlue in a diesel in Lambs Green: what it takes Wherever it has stopped in Lambs Green — a forecourt, a layby, a drive, a road beside Corfe Mullen Cemetery Chapel — our van comes to your vehicle. What went in, roughly how much, and if the engine has turned over: we check before all else, because those shape the job. Then that tank is drained where your car sits, so the polluted fuel and the AdBlue come out together. Your system is rinsed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. The majority of these jobs are a half-hour visit once our technicians get there, provided your motor hasn't run. Quiet enough to use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof. Priming your system with new diesel comes last. Whether it's a parking space outside Hamworthy or a driveway in Lambs Green, that is where our engineers fire it up and you head off. It's checked on fresh diesel to make sure it runs correctly before we head off. No garage is required at any stage, with the whole job done on the spot. Afterwards, you are given the paperwork for your insurer: a VAT invoice plus a report from the engineer. ## About Lambs Green, for a moment Lambs Green is a small suburban area in Dorset, situated inland at an elevation of 37 metres.

Guessing doesn't help by a border or somewhere hard to describe; ring and check. Lambs Green is a residential suburb, and a call-out drain suits it: whether the vehicle 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 AdBlue in a diesel tank costs to put right in Lambs Green There is no honest single price, since the jobs aren't the same. Three things change the cost: whether the motor has run and for how long, how much AdBlue was put in, and where the car is. That last one comes down to whether our van can get to it safely, and an open driveway is easier than a tight gap behind Eye bridge. Ahead of a figure, never after, each enquiry from Lambs Green begins with three questions: the liquid, the quantity, and whether the engine ran. Once they are answered, a range turns into one fixed number. You get that price on the phone, before anyone sets off, and you pay on the day, by card or over the phone, with nothing upfront. Check your policy while we're on the way: plenty carry misfuelling cover. ## Still alongside the vehicle around Lambs Green? Right now, the most helpful thing to do with your vehicle is to leave it. Keys out, engine off, ignition off. Petrol in Diesel takes over the remainder, in Lambs Green or wherever in Dorset, after you phone 0333 366 0103 to say it was AdBlue, about what quantity, and whether it ran.
