--- title: AdBlue in a Diesel Tank Fisherrow? Leave It Off canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/fisherrow-east-lothian/ location: Fisherrow county: East Lothian latitude: 55.942670 longitude: -3.061600 service: AdBlue in a Diesel Tank updated: 2026-10-06 --- # Don't Start It: AdBlue in a Diesel Tank in Fisherrow AdBlue in your diesel tank? Then leave the engine off — and your ignition too. AdBlue is urea dissolved in water. Being water-based, it won't burn and won't blend with diesel; trouble just comes when your pump begins pulling it. Caught before the motor has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where the car is in Fisherrow. First, call us on 0333 366 0103. ## What to do right now, Fisherrow: AdBlue in your diesel tank Do: - So no one can switch your ignition on, take your keys out. - If you're anywhere near moving traffic, put the hazard lights on. - The empty bottle or the till receipt shows us the fluid and the quantity, and so do not throw it away. - Tell us a postcode starting EH21 6, or whatever street is nearest, and our van reaches you straight — so call wherever you stand. Things not to do: - No starting your engine — not for a second, not to reposition your car. - Do not switch the ignition on. On plenty of diesels that alone runs the fuel pump. - Adding more diesel doesn't help: AdBlue separates out rather than blending. - Do not drive it anywhere, not even a short way down Campie Lane. - Do not try to drain the vehicle yourself at the roadside. The attendants working at any Fisherrow filling station — the Tesco among them — will normally help rolling it aside if you ask. Stopped on your own driveway? Then it remains just as it is. ## AdBlue in a diesel tank: what it does Not the motor but your exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into your exhaust gas to fresh it. No part inside an injection pump is designed for this fluid — and no part of it was meant to go through one. Inside a diesel tank it acts very differently from fuel. It does not mix in. It's heavier than diesel, and so it sinks and gathers at the bottom of that tank, which is where the pickup sucks fuel from. Simplest of all: a vehicle that got AdBlue in Stoneyhill last night and has not turned since. The AdBlue sits at the foot of your tank, undrawn — but it will be the first thing through if the motor starts, ahead of any diesel at all. Two kinds of harm follow from there. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filters and tiny channels; and, because it eats at some metals, every part it touches keeps suffering for as long as it remains in there. A motor left standing around Fisherrow with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. Water protects nothing. The injection pump and each injector depend on diesel flowing past them, so the water part harms them by itself. ## Why AdBlue in a diesel is often more significant than petrol Petrol pumped into a diesel on Shell's forecourt makes your fuel thin — that's the whole issue. Harm just comes from driving on it. Blended into the diesel and sitting inside that tank, it causes none. AdBlue in a diesel is a problem of the wrong substance altogether. Because it doesn't burn, running it through isn't an option. Nor can it be watered down, since it separates again — and the following fill won't rinse away crystals or corrosion. So the flush matters more here, and turning the key "to see", in the centre of Fisherrow or out in Goose Green, does more harm than almost any other slip. The good news is the same as with petrol. If the engine hasn't run, the AdBlue is still in the tank, and that tank is the easiest part of a fuel system to clear, wherever across East Lothian the vehicle is sitting. ## AdBlue in a diesel tank around Fisherrow: how it ends up there It's not deliberate. Many cars have the AdBlue inlet beside the diesel inlet, occasionally under one flap, and mixing them up is simple after dark. It usually takes place outside the house, from a bottle grabbed en route home, rather than at the filling station. The ways it occurs are few and familiar. Hurrying, outside the local primary school, after a warning lamp came on during the school run, a parent refills the vehicle. Close to Campie Road, someone pours a container in on the drive in the evening. Or a driver new to that flap tops up the car after dark, parked in the car park outside The Anchor Bar. It occurs 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. Same slip, same first response — keep it off — anywhere you are around Fisherrow or the remainder of East Lothian. ## AdBlue in the diesel tank in Fisherrow, and the motor started? The AdBlue has left the tank, then. The filter and pipework have had it sucked through, and some running carries it on to the high-pressure pump and each injector. Perhaps returning from River Esk Park, or part way across Fisherrow, the motor might run lumpy, smoke, drop pace, flash your dash or stall. When you safely can, pull over and turn it off — without turning it on again to see. More of it is pulled through with each start. Leave the M8, under 10 miles from Fisherrow, at the next junction and park safely, not driving on. Hopping across Fisherrow to the car park by OliveBank Community Centre is one thing; heading towards Edinburgh, under 10 miles away, is something else, because every mile pushes the AdBlue further in. So distance matters. Tell us about how far it had come. Wherever the vehicle came to a halt is where all of it gets done, even with more to flush once the motor has been running. Permanent damage is very uncommon when it is spotted early. ## What does an AdBlue drain on a diesel involve around Fisherrow? A street by Fisherrow Centre, a drive, a layby or a forecourt: anywhere the car has stopped in Fisherrow, our engineers travel to it. Three replies decide the job, so first our technicians ask which fluid went in, roughly what quantity, plus if your motor has turned over. Next, emptying that tank right there removes the contaminated diesel and the AdBlue in one go. A careful flush counts much more after AdBlue than with petrol, because what remains won't wash away by itself. Clean diesel goes in after the fuel filter is cleaned — or replaced, when it needs to be — and after that the vehicle is tested. Roughly half an hour on site is usual for most jobs when your motor has not run. Quiet enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof. The last step is to bleed the fuel system on clean diesel. Whether it's a parking space outside Musselburgh or a driveway in Fisherrow, that is where our engineers start the car and you drive off. Our technicians confirm it runs smoothly on new diesel before we go. We do it all wherever your car has ended up, and it never has to be taken to a workshop. The insurer is likely to want an engineer's report and your VAT invoice — each handed over once this job is done. ## About Fisherrow itself Fisherrow is a coastal suburban area in East Lothian, situated near the city of Edinburgh and close to the Firth of Forth.

A mobile service fits Fisherrow, a residential suburb: you have no need to bring the vehicle to us, because our technicians empty it there, on a driveway, a side street, a car park or a forecourt. ## What does AdBlue in a diesel tank cost to sort out around Fisherrow? Not one flat figure could be fair, since each job differs. Three things move the price: whether your engine has been running and for how long, how much AdBlue got in, and where the vehicle is. That last one comes down to whether our van can get to it safely, and an open driveway is simpler than a tight spot behind Olivebank Stadium. Which fluid got in, how much, and whether the engine ran: each Fisherrow enquiry begins with precisely those, ahead of any figure, not after. Their answers shrink a range right down to one figure. You hear that price by phone, before anybody sets off, and you pay on the day, by card or by phone, with nothing upfront. Check your policy while we are on the way: many include misfuelling cover. ## Beside the vehicle around Fisherrow, still? Then the most handy thing you can do is nothing to the vehicle. Keys out; motor and ignition off. Petrol in Diesel takes over the rest, in Fisherrow or wherever within East Lothian, once you call 0333 366 0103 to say it was AdBlue, roughly what quantity, and if the engine ran.
