--- title: AdBlue in a Diesel Tank Friars Cliff? Leave It Off canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/friars-cliff-dorset/ location: Friars Cliff county: Dorset latitude: 50.734040 longitude: -1.730520 service: AdBlue in a Diesel Tank updated: 2026-10-25 --- # Friars Cliff: AdBlue in the Diesel Tank? Leave It Off AdBlue in your diesel tank? Then keep your motor off — and the ignition too. In plain terms, AdBlue is simply urea in water. As it is water-based, it will not ignite and won't blend with diesel; trouble only starts when your pump starts drawing it. In Friars Cliff, AdBlue in a diesel tank found before your engine runs usually comes down to a drain and a thorough flush, right where the vehicle is. Before you do anything else, ring 0333 366 0103. ## Those opening minutes: AdBlue in your diesel tank around Friars Cliff Do: - So no one can turn your ignition on, take the keys away. - If you're anywhere near moving traffic, put the hazards on. - Keep the till receipt or the empty bottle, so you can tell us what went in and roughly how much. - Tell us a postcode starting BH23 4, or whichever street lies closest, and our van finds you directly — so ring from wherever you stand. Not to do: - Do not start the engine, even for a moment to shift the car. - Switching the key to ignition by itself sets the pump going on plenty of diesels. Avoid it. - Pouring in extra diesel does not work: AdBlue separates out rather than blending. - Keep the vehicle where it is instead of driving it anywhere, even a short distance down Southcliffe Road. - Beside the road, don't attempt emptying it on your own. Ask the attendants to help you roll the car off the pumps if you're at a forecourt in Friars Cliff, whether it's the Shell or elsewhere. Parked on your own driveway? Then it remains exactly as it is. ## AdBlue in a diesel tank, and what it does there The motor isn't what AdBlue is made for; the exhaust is. Stored in a dedicated tank, it's squirted into the exhaust to clean the gases. A fuel pump isn't made to cope with it, and AdBlue was never intended to go through one. Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. It is heavier than diesel, and so it sinks and gathers at the bottom of that tank, which is where the pickup pulls fuel from. A vehicle topped up on a drive in Stanpit overnight and not started since is the straightforward one. No pump has sucked the AdBlue up yet — though once the motor turns, that is what goes first, straight from the bottom of that tank. After it's drawn in, the harm takes two forms. What is left when the water evaporates is urea, which forms crystals: they settle in tiny passages and clog filters. Worse, it eats at certain metals in a fuel system, and carries on until it's cleared out. By daybreak, a vehicle parked in Friars Cliff with AdBlue in its lines gets worse; if it's only in your tank, nothing changes. The water in it causes damage of its own: the high-pressure fuel pump and the fuel injectors depend on diesel to lubricate them, and water gives them nothing. ## Why AdBlue in a diesel is regularly more serious than petrol Put petrol in a diesel at the BP and you have a fault of thin fuel. No damage comes as long as it sits put, mixed into the diesel — only once your engine runs on it. The trouble with AdBlue in a diesel is a totally wrong liquid. Because it doesn't burn, running it through is not an option. Whether the vehicle is in Purewell or the centre of Friars Cliff, turning it over "to see" does more harm with AdBlue than nearly any other slip, and the flush matters more. The reasons: it will not stay blended, and so watering it down is impossible; and deposits and corrosion outlast the next fill. The good news is the same as with petrol. If your motor has not run, the AdBlue is still in your tank, and your tank is the quickest part of a fuel system to clear, wherever across Dorset the vehicle is sitting. ## How AdBlue ends up in a diesel tank around Friars Cliff It's not on purpose. Many vehicles have the AdBlue inlet beside the diesel inlet, now and then behind a single flap, and muddling them up is easy in poor light. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the forecourt. It tends to take place in a few familiar ways. The refill is hurried outside Mudeford Junior School, because the dash lit up with a warning as the children were taken in. Someone pours the container in outside their house, just off Rook Hill Road, as the day ends. Or the car is topped up in the car park at The Sandpiper, in poor light, by somebody who has never opened that flap before. It crops up the most in a hire car, a brand-new motor, a company vehicle, or the spare motor of a family with one of each fuels — the vehicles drivers use least. Leave it off: that is the first response to an identical mistake, anywhere in Friars Cliff or the rest of Dorset you are. ## AdBlue in your diesel tank around Friars Cliff, and the motor started? The AdBlue has left that tank, then. With any running time, it travels to the high-pressure pump and every injector, after passing via your filter and pipework. Watch for lumpy running, exhaust smoke, lost power, warnings on the dash, or a cut-out — returning from Highcliffe Castle Golf Club, say, or part way across Friars Cliff. Once safe, pull over and switch everything off — with no turning it on again to see. Each start pulls more of it through. Friars Cliff sits under 15 miles from the M27; if you were on it, exit by the next junction and stop somewhere safe instead of driving on. Mileage matters: every mile carries the AdBlue further in, and so driving for Southampton, under 25 miles away, gives a far larger job than hopping across Friars Cliff to the car park by The Parish Church of All Saints. Tell us about how far it had come. Once the motor has been started, the flush includes more, and all of it is done where the vehicle has come to a stop. Long-term damage is very unusual when it's caught early. ## Friars Cliff: how AdBlue is emptied from a diesel A street by TK Maxx, a driveway, a lay-by or a forecourt: wherever your vehicle has stopped around Friars Cliff, our technicians travel to it. Three answers decide the work, so before anything else we ask what got in, roughly what quantity, and if your engine has run. On the spot, that tank is then drained, and both the contaminated diesel and the urea leave at once. Residue from AdBlue will not wash out unaided, so the whole system gets a careful flush, which counts far more with urea than with petrol. Testing the car comes at the end, once fresh diesel goes in and your filter gets flushed or, if necessary, replaced. If the engine has not run, most jobs take about half an hour once we arrive. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house after dark. Clean diesel goes in to prime your system, and that's the final step. Whether it is a parking space at Hinton Admiral or a driveway in Friars Cliff, that is where our engineers start it and you head off. The test before our engineers go is that it runs correctly on fresh diesel. We do it all wherever the car has stopped, and it never has to go to a workshop. You receive a VAT invoice and an engineer report later on, which is what insurers ask for. ## About Friars Cliff and where it is Friars Cliff is a coastal suburban area in Dorset, situated near the towns of Mudeford and Highcliffe.

What moves the price is, firstly, whether your engine has run and for how long; then how much AdBlue went in; and after that where your car is and whether a van can get to it safely, which is simpler on an open drive than in a tight gap behind Highcliffe Castle.
