--- title: AdBlue in a Diesel Tank Nailsbourne — Don't Start It canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/nailsbourne-somerset/ location: Nailsbourne county: Somerset latitude: 51.049410 longitude: -3.112780 service: AdBlue in a Diesel Tank updated: 2026-10-11 --- # Nailsbourne: AdBlue in the Diesel Tank? Leave It Off If AdBlue has got into the diesel tank, keep the motor off then leave your ignition off. Water with urea dissolved in it: that's AdBlue. Not like fuel, it neither burns nor mixes, and nothing happens until the engine sucks it round. If your motor has not run yet, AdBlue in a diesel tank is usually emptied and thoroughly purged where your car sits in Nailsbourne. Nothing comes before calling 0333 366 0103. ## Those opening minutes: AdBlue in your diesel tank around Nailsbourne Do these: - So no one can turn the ignition on, pull the keys away. - Near moving traffic? Then put the hazard lights on. - The empty bottle or the receipt tells us the product and the quantity, and so do not bin it away. - Ring us from where you are. A postcode starting TA2 8, or the name of the nearest street, brings the van to you without a search. Do not: - Don't start your motor, even for a moment to shift the vehicle. - Many diesels run their fuel pump the moment the ignition goes on, and so keep the car off. - Don't top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out. - Keep it where it is instead of driving it anywhere, even a short stretch along Pickney Lane. - Don't try to drain it yourself at the kerbside. Moving the car away from the island is a job for staff to help with, wherever Nailsbourne forecourt you are on, the Texaco included. If you're on your own drive, leave it just where it sits. ## AdBlue in a diesel tank, and what it does there Not the engine but the exhaust is where AdBlue is meant to go. Kept in a dedicated tank, it's squirted into the exhaust stream to clean the fumes. A fuel pump is not designed to take it, and AdBlue was never supposed to travel through one. Fuel mixes; AdBlue, once tipped in, won't. Its behaviour is not at all like fuel's. The intake sucks fuel from the lowest part of the tank, and that is precisely where AdBlue ends up: as it is denser than diesel, it sinks. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Kingston St Mary last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has drawn it in. From there it causes two kinds of harm. What is left once the water evaporates is urea, which forms crystals: they lodge in narrow channels and block filters. On top of that, it eats at some metals in a fuel system, and keeps going until it's flushed out. A car left standing in Nailsbourne with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Water protects nothing. The injection pump and each injector need diesel running through them, and so the water content damages them in its own right. ## Petrol or AdBlue in a diesel: why AdBlue is commonly worse Put petrol in a diesel at the BP and you have a fault of thin fuel. Mixed into the diesel and sitting unused, it's no threat at that stage; running your motor does the harm. AdBlue in a diesel is another matter: not thin fuel, but no fuel at all. Not burning, it cannot simply be run through. Whether the car is in Fulford or the centre of Nailsbourne, turning it over "to see" costs more in this case than nearly any other mistake, and the flush counts for more. Why: it won't stay blended, so watering it down fails; and crystals and corrosion outlast the next fill. With AdBlue, the good news is no distinct from petrol. Not run? Then the AdBlue waits only inside your tank, the easiest bit of the whole system to clear, anywhere your car has come to rest in Somerset. ## AdBlue in a diesel tank around Nailsbourne: how it ends up there In dim light, two caps together — the AdBlue one and the diesel cap, now and then under one flap — can appear the same. Nobody means it; many layouts invite it. Mostly it occurs with a bottle bought on the way home and poured in on the driveway, not at the pump. It tends to take place in a couple of familiar ways. A warning light comes on during the school run, and the top-up occurs in a hurry outside Kingston St Mary Church of England Primary School. A driver pours the container in at home, right off Kingston Road, as the day ends. Otherwise, in dim light outside The Swan at Kingston, the car is topped up by someone using that flap the first time. The least known vehicles get it the most — rentals, brand-new ones, company cars, and the spare car in a home with both fuel types. Wherever in Somerset, Nailsbourne as well, the mistake doesn't change, and nor does the first response: keep it switched off. ## Started the motor with AdBlue in your diesel tank in Nailsbourne? Then the tank is no longer where the AdBlue is. Via the fuel filter, through the pipework, and — given any running — on to the injection pump and every injector: that's how far it travels. Expect lumpy running, exhaust smoke, lost power, lights on your dash, or a stall — returning from Plot 17, perhaps, or part way across Nailsbourne. Pull over when it is safe. Turn off. Leave it off instead of restarting it to check. With each start, more of it is pulled through. On the M5, under 5 miles from Nailsbourne, the first junction is where to leave, and anywhere sensible is where to stop — not carrying on. A quick hop across Nailsbourne to the car park by Kingston Club is one matter; heading towards Wells, under 25 miles away, is something else, because each mile carries the AdBlue deeper in. So distance counts. About how far it had come is worth telling us. Once the motor has been run, the flush covers more, and all of it is done where the car has ended up. If it is spotted soon, lasting damage is very uncommon. ## What clearing AdBlue from a diesel involves around Nailsbourne The car stays put, whether that is a road beside Kingston St. Mary Village Hall, a driveway, a layby or a filling station around Nailsbourne, and the van comes to it. Three answers decide the job, and so first our technicians ask what was put in, about the amount, and if your motor has run. Right there, your tank is then emptied, and both the contaminated diesel and the urea come out at once. What remains from AdBlue will not wash out by itself, and so the fuel system gets a careful flush, which counts much more with urea than for petrol. The fuel filter is cleaned, 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 job once our technicians get there, if the engine hasn't run. The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house after dark. New diesel goes in to prime your system, and that's the final step. Whether it's a parking space at Taunton or a driveway in Nailsbourne, that is where we fire it up and you head off. The test before our engineers leave is that it runs properly on new diesel. As the job is done in its entirety where the car is, a workshop never comes into it. The insurer is likely to want an engineer's report and your VAT invoice — each handed over afterwards. ## About Nailsbourne and where it is Nailsbourne is a small village in inland Somerset, situated at an elevation of 57 metres, with detached housing being the predominant type of accommodation.

Since the callouts vary, a flat figure would not be fair. Three things shift the cost: whether the motor has been running and for how long, how much AdBlue got in, and where the vehicle is. That last one turns on whether our van can reach it safely, and an open drive is simpler than a tight space behind Wellsprings Leisure Centre. For that in mind, every enquiry from Nailsbourne opens by asking the identical trio — what got in, what quantity, if the engine ran — before a figure. Their replies narrow a range down to one figure. The price is quoted on the call, before anyone sets off; settling up comes on the day, by card or by phone, and nothing upfront. Misfuelling cover comes with plenty of insurance policies, so it pays to look at yours before the van arrives. ## Nailsbourne: still next to the vehicle? In that case, do nothing — that's the best step there is. Engine off, keys out, ignition off. Petrol in Diesel takes over the remainder, in Nailsbourne or wherever within Somerset, after you call 0333 366 0103 to say it was AdBlue, roughly what quantity, and whether the engine ran.
