--- title: What Now? AdBlue in a Diesel Tank Welling canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/welling-greater-london/ location: Welling county: Greater London latitude: 51.462320 longitude: 0.107320 service: AdBlue in a Diesel Tank updated: 2026-10-22 --- # Welling: AdBlue in the Diesel Tank? Find Your Situation One fact counts above all when AdBlue is in a diesel tank, and it is whether your engine has run afterwards. If it has not, keep it that way, whether your car is around Welling itself or out in Crook Log. Keep nothing on, call 0333 366 0103, then expect a thorough flush plus a drain, carried out just where your vehicle sits around Welling. Already run? Stop once safe, then turn everything off. Step one stays the same, even though the job is bigger. Wherever around Greater London it happened, one of the cases below matches yours. ## AdBlue in a diesel on a Welling forecourt You are 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. Possibly you're at the the nearest petrol station, possibly at the Shell, possibly somewhere else around Welling. Meaning? Spotting it on the forecourt is as good as it can be. No pump has drawn it in, and so the AdBlue stays just inside that tank. Freeing the pump is no reason to run it — and so do not get back in. Three things: a shove into a space with the attendants helping, the receipt saved, and a ring to us from the forecourt. Emptying it right at the petrol pump is fine if it can't be moved, because the equipment is explosion-proof. ## AdBlue in the diesel tank at home in Welling For days the dashboard had been nagging you. Picked up a bottle, tipped it in at home, binned the empty — and only then looked at the cap again, too late. It takes place on driveways just off Hook Lane as often as anywhere. The point: no driving since makes this almost as good to finding it at the petrol pump. As it is reluctant to mix, AdBlue settles low inside your tank and stays. A night standing changes nothing. Your move: the keys in the house, so nobody drives your vehicle anywhere at breakfast. After that, phone. We drain the vehicle on your driveway, whether that's in Welling or out in East Wickham. The pumps are quiet enough to use outside a house after dark. ## AdBlue in a diesel and already driving in Welling? Rough running, smoke, lost power or a glowing dashboard arrived a short way after the fill. Maybe it was on Welling High Street, perhaps on the way out towards London, under 10 miles away. What it means: your fuel system has sucked the AdBlue in. It's been through the filter and your lines and, the further you went, into your high-pressure pump and the injectors. Every restart, like every mile, carries it on. Next: pick a safe spot, pull in, then turn your engine off. Welling lies under 10 miles from the M25; on it, come off at the next junction instead of pushing on to the services. Starting it again to check achieves nothing — AdBlue doesn't clear on its own. Roughly how far did it go? Tell us as you phone. ## Hire, lease or company car with AdBlue in the wrong tank A week ago, the car was new to you. The AdBlue filler is right next to the diesel filler, which you didn't know, since your own vehicle either has no AdBlue or keeps it somewhere else. Anywhere you happen to be across Greater London, every motorist can slip up. What it means: the same as the situations above, depending on whether it has run, with one more stage. Plenty of hire and company agreements want the owner to approve work on your car. Sorting it before we turn up is faster, so ring the hire company or your fleet manager, then us. Keep it off as the reply arrives, whether you're waiting outside the nearest station or near Welling Library. ## AdBlue in the diesel tank? Not sure, in Welling Occasionally the fair answer is "I think so". The bottle is lighter than it should be, there is a faint smell of ammonia around the filler, and you can't remember which cap you took off. The gates of St Stephen's Catholic Primary School in a hurry, say, or a friend's driveway out in Bostall Woods. What it means: a little spilled round the filler does no damage to the motor. In the diesel tank, by contrast, AdBlue damages it. If there is AdBlue in that tank, turning on your car would suck it in, and it would not tell you which either. Next: assume it went in, then leave your engine off. Ring us and explain what you saw; we'd rather check a tank that turns out clean than drain one that has already been run. ## Every AdBlue drain around Welling shares these stages The work opens identically, whichever your situation. Three things are asked when our technicians reach the car — at a filling station, a drive, a road by The Salvation Army - Welling or the car park at The Hangar: the fluid, the amount, and if the motor has run. On the phone, before anything else, you hear our quote, and those replies shape the work too. A thorough flush follows this drain. With petrol it is standard; with AdBlue it's essential, because deposits build up and some metals are attacked, and none of that washes away unaided. Finally come the fuel filter, flushed or replaced if necessary; fresh diesel; and a test of the car. Not started? In that case roughly half an hour once we are there covers most jobs. Our engineers fire it up last. With clean diesel in, it runs while we confirm it's running smoothly, and then we leave. Our engineers do the whole job where the car is, and long-term damage is very rare when it has been caught quickly. Payment comes on the day, never upfront. For your insurer, there is a VAT invoice plus a written report from the engineer. Many insurance policies include misfuelling, so look at yours while the van travels. ## About Welling, for a moment Welling is a suburban area in southeast London, situated on the banks of the River Thames at an elevation of around 47 metres.
