--- title: Don't Start It: AdBlue in a Diesel Tank Nazeing Gate canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/nazeing-gate-essex/ location: Nazeing Gate county: Essex latitude: 51.726570 longitude: 0.042390 service: AdBlue in a Diesel Tank updated: 2026-10-13 --- # Nazeing Gate: AdBlue in the Diesel Tank? Leave It Off If AdBlue has gone into the diesel tank, keep your engine off then keep the ignition off. Water with urea dissolved in it: that is AdBlue. It does not burn, it doesn't mix with diesel, and the harm it does starts when the system pulls it in. A drain and a thorough flush, done where the vehicle is around Nazeing Gate, is normally all AdBlue in a diesel tank takes — if it is caught before your engine has been run. Phone 0333 366 0103 before you do anything else. ## Nazeing Gate, AdBlue in your diesel tank: what to do right away Things to do: - Take your keys out, and so nobody switches your ignition on. - Hazards on, if moving traffic is at all close. - So you can tell us which liquid it was and about what quantity, keep your receipt or the empty bottle. - Our van locates you quickest with a postcode starting EN9 2, or simply the name of a street close by, and so phone from the spot. Things not to do: - Not even for a second, and not to shift the car: the engine remains off. - Your ignition stays off: on lots of diesels, turning it on is enough to run the pump. - Do not top up with diesel to dilute it. AdBlue does not dilute in diesel; it separates out. - Any driving at all is to be avoided, even a short way along Nazeing Common. - Emptying the tank on your own beside the road is not worth trying. Ask the people behind the counter to help you roll the vehicle off the pumps if you're at a forecourt around Nazeing Gate, whether it is the BP or somewhere else. On your own drive, do not move it at all. ## What AdBlue does in a diesel tank Made for the exhaust, AdBlue has no place in your engine. Its own tank keeps it, and from there it's sprayed into the exhaust, and there it treats the fumes. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it. Tipped in with the diesel, it keeps separate instead of mixing — quite different from fuel. It drops, because it is heavier than diesel, and settles down where the pickup takes its supply from. Easiest of all: a vehicle that had AdBlue in Nazeing last night and has not turned since. The liquid sits at the foot of your tank, undrawn — but it would be the first thing through if the engine starts, ahead of any diesel at all. It causes two kinds of harm from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, and so it keeps labouring on the parts it hits for as long as it remains there. By daybreak, a vehicle sitting around Nazeing Gate with AdBlue through its pipework gets worse; if it is just in the tank, it doesn't. Diesel protects the high-pressure pump and every injector as it flows; water offers none of that, which is a second kind of harm. ## Petrol or AdBlue in a diesel: why AdBlue is regularly worse A problem of thinned fuel is what you get after fuelling a diesel with petrol at the Shell. It mixes with the diesel, and while it is inside your tank it does no harm; the damage comes from running the motor on it. The issue with AdBlue in a diesel is a completely wrong liquid. Since it does not burn, running it through isn't an option. It doesn't stay mixed, so it can't be thinned. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting your engine "to see" costs more here than almost anywhere else, whether the vehicle is in Claverhambury or the middle of Nazeing Gate. With AdBlue, the good news is no different from petrol. Not run? Then the AdBlue waits just inside the tank, the simplest section of the entire system to clear, wherever your vehicle has come to rest around Essex. ## How does AdBlue end up in a diesel tank in Nazeing Gate? Nobody means to do it. The AdBlue filler on many cars rests right next to your diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. A bottle picked up while driving home and tipped in outside the house, instead of at the forecourt, is the usual story. A few familiar ways account for most cases. A warning light comes on during the school run, and the top-up takes place in a hurry outside Nazeing Primary School. Close to Middle Street, a driver pours a container in on the drive after work. Another version: darkness, a pub car park by King Harolds Head, and someone using that flap the first time. Rented cars, new cars, fleet cars, or the spare vehicle in a family with both fuels: the least familiar vehicles get it most. Leave it switched off: that's the first step to the same slip, wherever in Nazeing Gate or the remainder of Essex you are. ## Nazeing Gate: started your engine with AdBlue in your diesel tank? The AdBlue has left the tank, then. Your filter and pipework have had it sucked along, and some running time takes it on to the injection pump and every injector. Maybe coming back from Nazeing Golf Club, or part way across Nazeing Gate, the engine may go rough, smoke, lose power, light up the dash or cut out. No starting it again to check: stop when it is safe, then switch it off. Every start pulls more of that through. Nazeing Gate lies under 3 miles from the M25; if you were on it, leave at the next junction and pull up somewhere safe rather than driving on. Hopping across Nazeing Gate to the car park by Nazeing Congregational Church is one matter; driving for London, under 25 miles away, is another, since each mile carries the AdBlue deeper in. So mileage counts. Approximately how far had it come? Tell us. Our engineers do all of the flushing where your car has come to a stop, and once your engine has been run there is more of it. Very seldom does it leave lasting damage when it's spotted early. ## What draining AdBlue from a diesel involves around Nazeing Gate The vehicle stays where it is, whether that is a street near Nazeing Common Cricket Club, a drive, a layby or a filling station around Nazeing Gate, and our van comes to it. Before anything else our technicians ask what got in, roughly how much, and if your motor has run, because those answers decide the work. On the spot, that tank is then emptied, and both the polluted diesel and the urea leave as one. Your system is cleaned thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. Clean diesel goes in once your filter is cleaned — or swapped, if it needs to be — and then your car is tested. If your engine hasn't run, the majority of jobs take about half an hour once our engineers arrive. Explosion-proof pumps mean a live forecourt sensible to work on, and they run quiet enough to spare the street at night. New diesel goes in to prime the fuel system, and that's the final step. You drive off as soon as our engineers have started it, and it makes no difference whether your car is on a driveway around Nazeing Gate or in a space by Broxbourne. The check before our technicians head off is that it runs properly on fresh diesel. Our engineers do it all wherever the vehicle has ended up, and it never has to be taken to a workshop. The insurer is likely to want an engineer's report and the VAT invoice — both yours afterwards. ## About Nazeing Gate and where it is Nazeing Gate is a small suburban area located on the riverside in Essex, with a relatively low elevation of 55 metres.

The cost moves first with how long, if at all, your engine has been running, and next with the amount of AdBlue that was put in. After that it depends on where your car is and whether a van can get to it safely, which is simpler on an open driveway than in a tight gap behind All Saints, Nazeing. What was put in, what quantity, plus whether it ran: each Nazeing Gate call begins with exactly that, ahead of a figure, not afterwards. When those are answered, a range becomes a single firm number. The price is given during the call, before a van sets off; payment happens on the day, by card or over the phone, with nothing upfront. Look at your insurance whilst we're on the way: many carry misfuelling cover. ## Nazeing Gate: still beside the car? Then the most helpful thing you can do is nothing to the vehicle. Keys out, engine off, ignition off. Phone 0333 366 0103: AdBlue, the amount, and whether it ran are everything our engineers ask. Petrol in Diesel handles the rest throughout Essex, Nazeing Gate included.
