--- title: AdBlue in a Diesel Tank Bishops Lydeard? Leave It Off canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/bishops-lydeard-somerset/ location: Bishops Lydeard county: Somerset latitude: 51.055590 longitude: -3.188450 service: AdBlue in a Diesel Tank updated: 2026-10-04 --- # Bishops Lydeard: AdBlue in the Diesel Tank? Leave It Off AdBlue in your diesel tank? Then leave the motor off — and the ignition too. Urea mixed in water is what AdBlue is. Unlike fuel, it neither burns nor blends, and no harm starts till your motor sucks it through. A drain and a thorough flush, done where your car is in Bishops Lydeard, is normally what AdBlue in a diesel tank needs — if it is caught before the motor has run. Ring 0333 366 0103 before you do anything else. ## Your next steps right now, Bishops Lydeard: AdBlue in your diesel tank Do: - Take your keys out, and so nobody switches your ignition on. - Put the hazard lights on if you're anywhere close to moving traffic. - The empty bottle or the receipt tells us the product and the amount, so do not bin it away. - Give us a postcode starting TA4 3, or whichever street lies nearest, and the van finds you directly — so call wherever you are. Never: - Not even for a second, and not to shift the vehicle: the engine stays off. - The ignition stays off: on many diesels, turning it on is enough to run your pump. - No more fuel added. The AdBlue will not mix, so it is pointless. - Any driving at all is to be avoided, even a short distance down Station Road. - Beside the road, do not try emptying it on your own. Moving the car off the island is a job for staff to help with, whichever Bishops Lydeard forecourt you're on, the Murco or any other. At your own drive, don't touch it at all. ## AdBlue in a diesel tank: what it does Not the engine but the exhaust is where AdBlue belongs. Its own reservoir holds it, and from there it's sprayed into your exhaust, and there it cleans the gas. Not one side suits the other: urea doesn't belong in an injection pump, and an injection pump can't deal with urea. Fuel blends; AdBlue, after poured in, will not. Its behaviour is nothing like fuel's. Heavier than diesel, it sinks and collects below it — the same spot the pickup sucks from. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Cotford St Luke last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in. From there it does two kinds of harm. What remains when the water evaporates is urea, which forms crystals: they lodge in narrow channels and block filters. Worse, it attacks certain metals in the fuel system, and carries on till it is cleared out. Lines holding AdBlue mean damage by morning for a vehicle sitting around Bishops Lydeard. Only in the tank, it stays stable. Then there's the water: it brings no protection to the parts that rely on it most — the high-pressure pump and every injector. ## Why is AdBlue in a diesel often the bigger problem? Put petrol in a diesel at the another forecourt nearby and you have a problem of thin fuel. No damage is done as long as it stays put, blended into the diesel — only once the engine runs on it. AdBlue in a diesel is another problem: not thin fuel, but no fuel at all. It does not burn, so it cannot just be run through. Deposits and corrosion remain through the following tankful, and AdBlue separates back out of your diesel, so watering it won't help. Hence the flush matters more, and trying the engine "to see" does more harm with AdBlue than almost any other slip — in East Combe or the centre of Bishops Lydeard equally. As with petrol, there's good news. If the engine hasn't run, the AdBlue is still in your tank, and the tank is the simplest part of a fuel system to clear, wherever around Somerset the car is standing. ## AdBlue in a diesel tank around Bishops Lydeard: how it ends up there After dark, two caps side by side — the AdBlue cap and the diesel one, now and then behind a single flap — may appear the same. Nobody intends it; many layouts invite it. Most of the time it takes place 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. Hurrying, outside Bishops Lydeard Church School, after a warning lamp flashed on during the school run, someone tops up your car. Someone tips the bottle in at home, right off Mount Street, as the day ends. Otherwise, in dim light outside The Lethbridge Arms, your car is refilled by a driver using that flap the first time. Rented vehicles, new motors, company motors, or the second vehicle in a home with one of each: the least familiar vehicles see it the most. An identical mistake, same first step — leave it off — anywhere you happen to be in Bishops Lydeard or the rest of Somerset. ## AdBlue in the diesel tank in Bishops Lydeard, and the engine started? Then the tank is no longer where the AdBlue is. The filter and pipework have had it sucked through, and any running carries it on to the high-pressure pump and every injector. Rough running, smoke, lost power, dashboard warnings or stalling: each might appear, maybe part way across Bishops Lydeard or returning from Greenway Wood. No restarting to check: pull over when safe, then turn it off. With each start, more of that is pulled through. If you were on the M5, under 10 miles from Bishops Lydeard, come off at the next junction and stop somewhere safe instead of pressing on. Hopping across Bishops Lydeard to the car park by Bishops Lydeard Mill is one matter; heading towards Wells, under 50 miles away, is something else, because each mile pushes the AdBlue deeper in. So mileage matters. Tell us about how far it had come. Our technicians do all of the rinsing where the vehicle has ended up, and once the engine has been started there is more of it. Very seldom does it leave lasting damage if it is spotted soon. ## Clearing AdBlue in a diesel around Bishops Lydeard: what it takes A street by The Mill House, a drive, a layby or a filling station: anywhere your vehicle has stopped in Bishops Lydeard, we travel to it. What went in, about how much, and whether your motor has turned over: our technicians ask before all else, since those decide the work. Then the tank is emptied where your car sits, and so the tainted fuel and the AdBlue come out together. With AdBlue, more so than with petrol, flushing counts: the fuel system is flushed all the way through since what remains will not wash out unaided. Testing your vehicle comes at the end, after fresh diesel goes in and the fuel filter gets flushed or, where necessary, replaced. Most of these jobs are a half-hour job once we arrive, if your motor hasn't run. The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house after dark. The last step is to bleed the system on clean diesel. After that our technicians start the engine and you head off, whether from a parking bay by Taunton or a driveway around Bishops Lydeard. It's tested on fresh diesel to confirm it runs correctly before we leave. Since the job is done in its entirety where your car is, a workshop never comes into it. Insurers want a VAT invoice and an engineer report, and you get both afterwards. ## About Bishops Lydeard, briefly Bishops Lydeard is a village situated in the Somerset countryside, near the River Tone and close to the Quantock Hills.

If you're close to a boundary, or somewhere hard to explain, ring and ask rather than assuming. No moving is needed.

Every job differs, so not one fixed quote is honest. Whether the motor has run, and for how long, comes first in what changes the cost. How much AdBlue went in comes next, and then the position of your car, because an open drive is easier for a technician to reach safely than a tight spot behind Bishops Lydeard Village Hall. What was put in, how much, plus whether it ran: each Bishops Lydeard enquiry begins by asking exactly those, ahead of any figure, never afterwards. Their replies narrow the range right down to one number. Priced on the call before the engineer heads out, it is settled on the day — card or phone, no deposit. While our engineer is on the way, check your policy: plenty include misfuelling. ## Bishops Lydeard: still beside your car? Then, do nothing — that's the best step available. Engine off, keys out, ignition off. Ring 0333 366 0103 then tell us it's AdBlue, about how much, and if it's run. Petrol in Diesel takes it from there, in Bishops Lydeard or anywhere in Somerset.
