--- title: The Causeway: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/the-causeway-wiltshire/ location: The Causeway county: Wiltshire latitude: 51.082760 longitude: -2.258330 service: AdBlue in a Diesel Tank updated: 2026-10-11 --- # What Now? AdBlue in the Diesel Tank in The Causeway One fact counts most once AdBlue is in a diesel tank, and it is whether the engine has been started afterwards. Anywhere your car stands — Ivy Mead, The Causeway — never run an engine that hasn't been started yet. Keep nothing on, phone 0333 366 0103, and expect a thorough flush plus a drain, done right where the car sits around The Causeway. If it has run, stop as soon as it is safe then switch off. A larger job, yes, but the identical opening move. Compare your case to a situation from the ones below, wherever around Wiltshire you happen to be. ## AdBlue in a diesel on a The Causeway forecourt You're at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Somewhere in The Causeway, then — Gulf, Esso, or somewhere else close by. Meaning? Finding out here is as good as it gets. Still inside the tank, and no fuel drawn through: that's where the AdBlue sits. Clearing the pump is no excuse to start it — so do not get back in. Have the attendants to help rolling it to a bay, save the receipt, then phone us from there. If it can't be shifted, it can be drained at the pump: the equipment is explosion-proof and safe on a working forecourt. ## The Causeway, at home: AdBlue in the diesel tank On your dash, a reminder had been lit for days. Only at the recycling bin, the empty container in hand, did you glance back at the cap you'd opened at the drive. Driveways close to Balmoor Close get it as much as anywhere. Meaning? Provided your car has not been driven since, it's close to the forecourt case. At the floor of the tank is where AdBlue stays, since it will not mix with diesel — and a night passing makes nothing of the difference. Next: stop an early drive by keeping your keys in the house, then phone us. We drain the vehicle on your driveway, whether that's in The Causeway or out in Southbrook. The pumps are quiet enough to use outside a house at night. ## AdBlue in a diesel and already driving around The Causeway? Lumpy running, smoke, falling power or a glowing dashboard arrived a mile or two after the top-up. It might have been driving for Wells, under 25 miles away, or simply along The Bartletts. Meaning? Your fuel pump has sucked the AdBlue up. The injection pump and every injector get it as well on a bigger trip, after the filter and pipework have had it. It goes further with every extra mile covered and every restart. Next: find a safe place, pull in, and switch the motor off. Leave by the first junction — not the services further along — if you're on the M4, under 50 miles from The Causeway. It won't have cleared, so there's no point restarting to find out. Phone us and say how far you went. ## AdBlue in the wrong tank of a hire, lease or company car You have had this vehicle hardly a week. The AdBlue filler sits right alongside the diesel one, which you did not know, because your own motor either has no AdBlue or keeps it somewhere else. Throughout Wiltshire, no one is safe from it. What it means: the same as the scenarios above, depending on whether it's run, with one more stage. The owner frequently needs to approve the work, under many rental and fleet agreements. Sorting it before the van turn up is faster, so ring the rental company or your fleet manager, then us. Hanging on for a reply in the car park at Gillingham (Dorset), or beside St Michael the Archangel? Keep your engine off throughout. ## The Causeway: unsure whether it was AdBlue in your diesel tank? At times, "I think so" is all anyone can honestly say. Which cap came off, you cannot recall; meanwhile the bottle weighs less than it ought to, and ammonia hangs by your filler. Maybe on a friend's drive in Mere, or rushing outside Mere School at the school run. Meaning? Drips around the inlet don't touch the engine at all. If it is inside your diesel tank, though, that changes. Starting the car won't tell you which, and if there is AdBlue in the tank it will suck it in. Next: assume it got in, and keep the motor off. Call us and explain what you saw; we would rather check a tank that turns out clean than drain one that has already been run. ## The common ground in each The Causeway AdBlue drain The work opens identically, whichever the case. Forecourt, drive, Walnut Tree Inn's car park or a road beside Mere Museum — our van comes to the car, and three questions follow: which fluid, what quantity, and whether it has run. Over the phone, before anything else, you hear the price, and those replies decide the job too. AdBlue forms crystals and is corrosive to some metals used in fuel systems, and so it won't rinse out unaided; that's why a full flush, after the drain, matters much more with AdBlue than with petrol. Fresh diesel is put in after your filter is cleaned or replaced, and your car is then tested. If your engine hasn't run, the majority of jobs take about half an hour once we're there. We fire it up at the end. Our test that it runs properly on clean diesel comes before our technicians head off. Lasting damage is very uncommon if it's spotted soon, and the entire job is done where the vehicle is. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, nothing upfront. Plenty of insurance policies include misfuelling, so check yours as we head over. ## About The Causeway, briefly The Causeway is a suburban area in Wiltshire, situated on the riverside at an elevation of 97 metres.
