--- title: Don't Start It: AdBlue in a Diesel Tank High Salvington canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/high-salvington-west-sussex/ location: High Salvington county: West Sussex latitude: 50.846590 longitude: -0.409020 service: AdBlue in a Diesel Tank updated: 2026-10-10 --- # AdBlue in a Diesel Tank in High Salvington? Don't Start It If AdBlue has got into your diesel tank, keep your motor off then keep the ignition off. Water with urea mixed in it: that's AdBlue. Unlike fuel, it neither burns nor mixes, and nothing happens until the engine pulls it through. In High Salvington, AdBlue in a diesel tank caught before your motor runs usually comes down to a drain and a thorough flush, just where your car is. Before you do anything else, call 0333 366 0103. ## Your next steps right now, High Salvington: AdBlue in your diesel tank Do these: - Remove the keys, and that stops anyone switching the electrics on. - Put the hazard lights on if you are anywhere close to moving traffic. - The empty bottle or the receipt shows us the product and the amount, and so do not throw it away. - Ring right where you are. Say a BN13 3 postcode or the closest street name, and nobody has to search for you. Things not to do: - Shifting the car just a short way is no reason to start the motor. - Plenty of diesels power their pump the moment the ignition comes on, so keep it off. - Pouring in extra diesel does not help: AdBlue separates out instead of blending. - Don't drive the car anywhere, not even a short way up Salvington Hill. - Beside the road, don't try draining it on your own. Get the attendants to help you roll the vehicle away from the pumps if you are on a forecourt in High Salvington, whether it's the Esso or somewhere else. Parked on your own driveway? Then it stays exactly where it is. ## What AdBlue does in a diesel tank The engine is not what AdBlue is made for; the exhaust is. It goes into its own tank and is sprayed into your exhaust gas to fresh it. A fuel pump isn't made to cope with it, and AdBlue was never supposed to go through one. It doesn't blend. Once it is tipped into the tank, AdBlue behaves not at all like diesel. It is heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup sucks fuel from. The first thing your fuel system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in West Durrington last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of that tank, and nothing has drawn it in. Two kinds of harm follow from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps working on the parts it reaches for as long as it stays there. Pipes carrying AdBlue spell harm by morning for a car sitting in High Salvington. Only inside that tank, it stays the same. The water in it causes damage of its own: your high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water gives them nothing. ## Petrol or AdBlue in a diesel: why AdBlue is regularly worse An issue of thinned fuel is what you get from fuelling a diesel with petrol at the BP. No harm comes as long as it sits put, blended into the diesel — only when your motor runs on it. AdBlue in a diesel is an issue of the wrong substance altogether. Because it doesn't burn, running it through is not an option. Whether the car is in Nepcote or the heart of High Salvington, turning it over "to see" costs more in this case than almost any other slip, and the flush matters for more. Why: it will not stay blended, and so watering it down is impossible; and crystals and corrosion survive the next fill. The good news is the same as with petrol. Clearing a tank is the simplest job on a fuel system, and with no running, the AdBlue remains in it — anywhere around West Sussex the vehicle sits. ## How AdBlue ends up in a diesel tank around High Salvington After dark, two caps side by side — the AdBlue one and the diesel cap, now and then under a single flap — can look the same. Nobody means it; plenty of designs invite it. Mostly it happens 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 couple of familiar ways. Rushing, outside Vale School, Worthing, after a warning lamp flashed on during the school run, someone refills the vehicle. After work, a container is tipped in on a driveway near Palmers Way. Or your car is topped up in the car park outside The Refreshment Rooms, in poor light, by someone who has never opened that flap before. It happens most in the vehicles people know least: a hire car, a new vehicle, a company car, or the second motor of a household with one diesel and one petrol. Leave it off: that is the first step to an identical slip, anywhere in High Salvington or the rest of West Sussex you are. ## AdBlue in the diesel tank around High Salvington, and your engine started? If so, the AdBlue is no longer inside your tank. It has been sucked through the filter and the fuel lines, and if the engine ran for any time, it has got to the high-pressure fuel pump and the injectors. Perhaps coming back from Honeysuckle Lane Open Space, or part way across High Salvington, your motor might run rough, smoke, drop power, flash the dash or stall. Stop as soon as it is safe, switch off, and do not restart the car to check. More of it is pulled through with each start. High Salvington sits under 25 miles from the M23; if you were on it, exit at the first junction and stop safely instead of driving on. A quick hop across High Salvington to the car park by St Peter is one matter; heading for Brighton and Hove, under 15 miles away, is something else, since every mile pushes the AdBlue further in. So mileage counts. Approximately how far had it come? Tell us. Our technicians do all of the rinsing where your car has come to a stop, and once the motor has been started there is more of it. Permanent damage is very unusual when it's spotted soon. ## Clearing AdBlue in a diesel around High Salvington: what it takes The car remains where it is, whether that's a road beside High Salvington Windmill, a drive, a lay-by or a forecourt in High Salvington, and the van comes to it. Which fluid got in, roughly the quantity, plus whether the motor has turned over: our engineers check first, since those decide the job. Then that tank is cleared where your car sits, so the polluted fuel and the AdBlue come out together. A careful flush counts much more with AdBlue than with petrol, because residue will not clear away by itself. A test of the car follows last, once fresh diesel is added and the filter is flushed or, where needed, swapped. Roughly half an hour on site is usual for most jobs when your motor hasn't run. Explosion-proof pumps mean a busy forecourt sensible to work on, and they run quiet enough not to disturb the neighbours at night. Finally, your system is bled with new diesel. Whether it is a parking bay at Durrington-On-Sea or a drive in High Salvington, that is where our engineers start it and you head off. It is checked on clean diesel to confirm it runs smoothly before our engineers leave. The entire job is done where your car is, so it never needs to be taken to a workshop. Afterwards, you are given the paperwork for the insurer: a VAT invoice and a report from the engineer. ## About High Salvington, briefly High Salvington is a suburban area in West Sussex, situated approximately 11.7 miles northwest of Brighton and Hove.
