--- title: AdBlue in a Diesel Tank Broadfield — Don't Start It canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/broadfield-lancashire-bb5-3/ location: Broadfield county: Lancashire latitude: 53.737110 longitude: -2.383810 service: AdBlue in a Diesel Tank updated: 2026-10-08 --- # Don't Start It: AdBlue in a Diesel Tank in Broadfield With AdBlue in the diesel tank, the ignition stays off and so does the motor. Chemically, AdBlue is just urea in water. The trouble begins once it's sucked through the pump — it won't burn, and it won't blend with diesel. If your motor has not run yet, AdBlue in a diesel tank is usually emptied and thoroughly flushed where the vehicle stands around Broadfield. Before you do anything else, phone 0333 366 0103. ## Broadfield, AdBlue in your diesel tank: what to do right away Things to do: - So nobody can switch your ignition on, take the keys away. - If you are at all close to moving traffic, put the hazards on. - Keep your receipt or the empty bottle, so you can tell us what went in and roughly how much. - Tell us a postcode starting BB5 3, or whichever street is nearest, and our van finds you directly — so call wherever you are. Not to do: - Shifting the car even a few yards is no reason to start your motor. - Don't switch the ignition on. On plenty of diesels that alone runs the fuel pump. - No extra fuel added. The AdBlue won't blend, and so it is pointless. - Even a short way along Pot House Lane is too far to drive the car. - No emptying it yourself, at all, at the verge. At a forecourt in Broadfield, whether it is the Esso or another one, ask the staff to help you push the car away from the pump. On your own drive, don't move it at all. ## What AdBlue does in a diesel tank The engine is not what AdBlue is made for; the exhaust is. Kept in a separate tank, it is squirted into the exhaust stream to clean the gases. A fuel pump is not designed to take it, and AdBlue was never supposed to travel through one. Tipped in with the diesel, it stays apart rather than blending — entirely unlike fuel. The intake takes fuel from the deepest part of your tank, and that's precisely where AdBlue ends up: being 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 Fern Gore last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in. From there it does two kinds of harm. What is left once the water evaporates is urea, which turns into crystals: they settle in tiny channels and clog filters. Worse, it attacks certain metals in the fuel system, and carries on until it is flushed out. A vehicle left sitting around Broadfield with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Diesel lubricates the high-pressure pump and every injector as it flows; water gives none of that, and that is a second kind of damage. ## AdBlue in a diesel: why it is often worse than petrol Top up a diesel with petrol by mistake at the Asda, and the issue is thinned fuel. Blended into the diesel and left unused, it's harmless at that stage; running the engine does the damage. With AdBlue in a diesel, the fluid as such is simply the wrong one. Since it does not burn, running it through isn't an option. Deposits and corrosion remain through the following fill, and AdBlue separates again from your diesel, so watering it can't work. That is why the flush matters more, and trying your engine "to see" costs more here than nearly any other slip — in Green Haworth or the centre of Broadfield alike. With AdBlue, the good news is no different from petrol. Not run? Then the AdBlue waits only in that tank, the simplest section of the entire system to clear, anywhere your car has come to rest across Lancashire. ## How AdBlue ends up in a diesel tank around Broadfield It's not deliberate. Many vehicles keep the AdBlue inlet beside the diesel one, occasionally behind one flap, and muddling them up is simple after dark. Mostly it's never the filling station: a driver buys a bottle driving home and pours it in outside the house. Usually, it happens in one of a few familiar ways. Hurrying, outside St Peter's CofE Primary School, after a warning lamp came on during the school run, a parent tops up the car. A bottle is poured in at the end of the day on a drive just off Broadfield. One more version: darkness, a pub car park outside Stop and Rest, and a driver using that flap the first time. The least known vehicles see it the most — hire cars, brand-new ones, fleet cars, and the spare vehicle of a home with both fuel types. Wherever across Lancashire, Broadfield as well, the mistake does not change, and nor does the first step: leave it switched off. ## Broadfield: started your engine with AdBlue in the diesel tank? In that case, the AdBlue is no longer in the tank. With any running time, it goes on to the injection pump and every injector, having passed via the filter and pipework. Lumpy running, smoke from the exhaust, dropping power, dashboard lights or stalling: any might appear, maybe midway across Broadfield or coming back from Rhyddings Park. When safe, pull over and switch everything off — with no turning it on again to see. With each start, more of it is pulled through. On the M65, under 3 miles from Broadfield, the first junction is where to leave, and somewhere sensible is where to park — not carrying on. Mileage counts: each mile pushes the AdBlue further in, so heading towards Preston, under 15 miles away, makes a much larger job than crossing Broadfield to the car park by St Paul. Approximately how far had it come? Tell us. We do all of the flushing where your car has ended up, and once the engine has been run there is more of it. Very rarely does it leave permanent damage if it is noticed soon. ## Broadfield: how AdBlue is cleared from a diesel The vehicle stays where it is, whether that's a street near Brave Church, a drive, a lay-by or a forecourt in Broadfield, and the van comes to it. Which fluid was put in, roughly the quantity, and whether your motor has turned over: our technicians ask before all else, because those decide the job. Then that tank is cleared where your car waits, so the polluted fuel and the AdBlue come out together. What remains from AdBlue will not wash out by itself, so the whole system gets a careful flush, which counts far more with urea than for petrol. Next, your filter: cleaned, or replaced if it has to be. After that fresh diesel, then a test of your vehicle. Roughly half an hour once we arrive is typical for most jobs where the engine hasn't run. Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough not to disturb the street at night. Priming your system with fresh diesel comes at the end. After that we start it and you drive off, whether from a parking bay at Church & Oswaldtwistle or a driveway around Broadfield. Before leaving, we make sure it's running correctly with new diesel in. Since the job is done in full where the car is, a workshop never comes into it. The insurer is likely to want an engineer's report and the VAT invoice — both yours afterwards. ## About Broadfield itself Broadfield is a suburban area in Lancashire, situated near the River Ribble and characterised by semi-detached housing. Broadfield sits at an elevation of 207 metres, overlooking the surrounding countryside. Broadfield is located near several smaller communities, including Hoyle Bottom and Miller Fold, and is approximately 13 miles from Preston. Broadfield is a relatively small suburban area, with a population of around 1723 residents. ## AdBlue drains across Lancashire, Broadfield included AdBlue call-outs in Broadfield are passed to vans that serve the places around it — Hoyle Bottom, Dunnyshop plus Miller Fold — and much of Lancashire further out, across BB postcodes. Ring and ask instead of guessing when you are by a border, or somewhere tricky to pin down. A van that comes to you suits Broadfield, a residential suburb: you have no need to take your vehicle to us, because our engineers drain it there, in a driveway, a residential street, a car park or a forecourt. ## AdBlue in a diesel tank around Broadfield: the cost of fixing it Every job differs, and so no fixed price would be fair. Whether your engine has run, and for how long, comes first in what changes the price. How much AdBlue went in comes next, and then the location of your car, because an open driveway is simpler for a van to reach safely than a tight gap behind Oswaldtwistle Library. With that reason, every call from Broadfield opens with the identical trio — what went in, what quantity, whether it ran — ahead of any quote. The answers turn a range into a straight price. The quote is given on the call, before anyone leaves; payment happens on the day, by card or over the phone, and nothing upfront. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we are on the way. ## In Broadfield and still next to your car? Then the most helpful thing you can do is nothing to your car. Engine off, keys out, ignition off. Tell us it's AdBlue, about how big an amount, and whether the engine ran, on 0333 366 0103. After that Petrol in Diesel takes over, across Broadfield or wherever within Lancashire.
