--- title: What Now? AdBlue in a Diesel Tank Wilsom canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/wilsom-hampshire/ location: Wilsom county: Hampshire latitude: 51.150180 longitude: -0.964840 service: AdBlue in a Diesel Tank updated: 2026-10-20 --- # AdBlue in the Diesel Tank in Wilsom, and What to Do Next One fact matters above all when AdBlue is in a diesel tank, and that is if the engine has been started since. Over in Mount Pleasant or right in Wilsom, an unrun motor should stay unrun. Usually that means draining and properly rinsing it right there around Wilsom — and so keep your ignition and engine off and call 0333 366 0103. When your motor has run, stop somewhere safe straight away, then turn the vehicle off. It's a larger job, yet step one does not change. Wherever around Hampshire it happened, one of the situations below fits yours. ## AdBlue in a diesel on a Wilsom forecourt You're at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Be it the nearest petrol station, BP or anywhere else in Wilsom, the case is identical. Meaning? Spotting it here is the best it can be. Only the tank has AdBlue; no part beyond it has taken any in. Freeing the petrol pump is no excuse to run it — and so do not get back in. Have the attendants to lend a hand pushing it to a bay, hold on to the bottle, then ring us from there. Our equipment is explosion-proof and fine on a live forecourt, so a vehicle that can't be pushed away is drained right at the petrol pump. ## At home around Wilsom with AdBlue in your diesel tank Days had passed with the dash light on. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look once more at the cap. Right off Wilsom Close is not less likely from any other place. The point: no miles since leaves it nearly as good to spotting it at the petrol pump. At the bottom of the tank sits where AdBlue stays, since it will not blend with diesel — and a night going by changes no difference. Keep your keys in the house tonight — or a person might take it off first thing — then call us. Your drive is where it is emptied, whether in Wilsom or Spitalhatch. Even at night, our pumps stay quiet enough for a residential street. ## Wilsom: set off with AdBlue in a diesel? Rough running, smoke, lost power or a glowing dashboard started a mile or two after the top-up. Wilsom Road, perhaps, or the route towards Winchester — a trip of under 25 miles. What it means: the fuel system has sucked the AdBlue in. Through your filter, through the pipework, and — the more the distance — on into the injection pump and each injector. More driving, more starts: further it goes. Do this: stop somewhere safe, then switch the motor off. Leave at the first junction — not the services beyond — if you're on the M3, under 10 miles from Wilsom. It won't have cleared, so there is no point starting it again to check. Phone, and say how far the vehicle was driven. ## AdBlue in the wrong tank of a hire, lease or company car Seven days back, the car was new to you. On your own vehicle, AdBlue is absent or somewhere else. On this one, its inlet is just next to your diesel cap — a surprise to you. Across Hampshire, nobody is immune. The upshot: just as above, divided by whether it ran, but with an added step. Many hire and fleet agreements need the owner's sign-off before repairs. Your move: rental firm or your fleet manager to begin with, us next, since sorting it early saves time. Leave the car off while the answer arrives, whether you are waiting at Alton or close to Saint Mary's RC Church. ## Unsure about AdBlue in the diesel tank around Wilsom? Now and then, "I think so" is the most anyone can truthfully say. The bottle is lighter than it should be, there is a faint smell of ammonia round the filler, and you cannot remember which cap you took off. Maybe it happened in a hurry at the school gates at Alton Infant School, or on a friend's drive in Newtown. Meaning? Drips outside the inlet don't touch the motor at all. AdBlue inside the diesel tank does. Any AdBlue in the tank will be sucked in by firing up the car, and the start would not settle which it is in any case. Do this: behave as if it did, and never start the engine. Inspecting a tank that proves free of AdBlue is better than draining one once it's been run — so ring then tell us what you saw. ## What each AdBlue drain in Wilsom has in common No matter the situation, one opening applies. Filling station, drive, The Railway Arms's car park or a road beside Curtis Museum — our van comes to the vehicle, and three answers follow: what fluid, what amount, and whether it ran. On the phone, ahead of anything else, you hear the price, and those answers shape the job too. AdBlue forms crystals and eats at certain metals in fuel systems, so it does not rinse out unaided; that is why the flush, after this drain, matters much more with AdBlue than with petrol. Clean diesel goes in after the fuel filter has been flushed or changed, and the car is then checked. The majority of unrun vehicles are a half-hour job after the moment our engineers arrive. Finally, our technicians fire it up. With clean diesel in, it runs while we make sure it's running properly, and then we head off. The whole job is done where the vehicle is, and if it's caught quickly, permanent damage is very unusual. Payment is on the day, never in advance. For the insurer, you get a VAT invoice and a report from the engineer. Many insurance policies include misfuelling, and so check yours as we head over. ## About Wilsom itself Wilsom is a locality situated on the riverside in Hampshire, with an elevation of 106 metres.
