--- title: AdBlue in a Diesel Tank Shortlanesend? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/shortlanesend-cornwall/ location: Shortlanesend county: Cornwall latitude: 50.286990 longitude: -5.080230 service: AdBlue in a Diesel Tank updated: 2026-10-19 --- # Shortlanesend: AdBlue in the Diesel Tank? Find Your Situation What to do about AdBlue in a diesel tank comes down to one thing more than any other: whether the motor has run since it got in. If it has not, keep it that way, whether the car is in Shortlanesend itself or out in Kenwyn. Normally this is emptying and properly cleaning it right there in Shortlanesend — and so leave the key and motor off and ring 0333 366 0103. Where the engine has run, pull in safely straight away, then turn it off. It is a bigger job, yet stage one does not change. Further down: the cases we meet, wherever in Cornwall. Choose yours. ## At the petrol pump in Shortlanesend: AdBlue in a diesel 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. Anywhere in Shortlanesend, then — Sainsbury's, Shell, or somewhere else close by. In short: there is no better place exists to spot it. The AdBlue is inside the tank and nowhere else. Nothing has sucked it in. Freeing the pump is no excuse to run it — so do not get back in. Three jobs: a push into a bay with the attendants assisting, the bottle kept, and a call to us from the forecourt. Our equipment is explosion-proof and fine on a busy forecourt, and so a car that can't be pushed away gets emptied right at the petrol pump. ## AdBlue in the diesel tank on a Shortlanesend drive? The warning light had been on for days. Only at the recycling bin, the empty container in your hand, did you look back at the cap you'd used at the driveway. Homes just off Hillcrest get hit as often as anywhere else. Meaning? Provided your vehicle hasn't moved since, it's second to the forecourt case. Diesel and AdBlue stay separate: the AdBlue drops to the floor of that tank and stays put, however long the night. What to do: leave the keys inside the house so nobody moves your car in the morning. Then call. Your driveway is where it gets emptied, be it in Shortlanesend or Roseworthy. The pumps are quiet enough to use outside a house after dark. ## Set off with AdBlue in a diesel around Shortlanesend? Filled up, pulled away, and soon the engine was running roughly, smoking, losing power, or flashing up your dash. School Hill, perhaps, or the way to Truro — a trip of under 3 miles. The upshot: your system has pulled AdBlue in by now. Mileage decides how far it gets: filter and lines to begin with, then the injection pump and each injector. More driving, more restarts: further it travels. Pull in safely — that's the next step — then switch it off. Services further along can wait: on the M5, over 50 miles out of Shortlanesend, use the first junction. It won't have cleared, so there is no point restarting to check. Ring us and say how far you travelled. ## A hire or company car with AdBlue in the wrong tank? You have had the car hardly a week. On your own car, AdBlue is absent or elsewhere. On this one, its cap is just by your diesel inlet — a surprise to you. It can happen to anyone, anywhere across Cornwall. Put simply: an extra step on top of the cases above, which turn on if it's run. Work on the vehicle often needs the owner's approval under hire or company terms. What to do: call the hire firm or your fleet manager first, then us. That's quicker settled before we turn up than after. If you are stuck in the car park at Truro, or by Shortlanesend Community Centre, while you wait for an answer, leave the car off. ## Shortlanesend: unsure if it was AdBlue in your diesel tank? "I think so" is often the most honest answer there is. A faint ammonia-like whiff hangs near your filler, the bottle seems too light, and which cap came off is a blur. Maybe at a friend's drive in Treliske, or rushing by Shortlanesend School at the school run. The point: your motor is not harmed by a little AdBlue splashed around the outside. Once it's inside your diesel tank, though, it does. Any AdBlue in your tank would be drawn in by turning on the vehicle, and the start wouldn't settle which it is in any case. Next: assume it got in, and leave the engine off. Tell us what you saw on the phone. A clean tank looked at is a better outcome than an already-run one drained. ## Shortlanesend: what each AdBlue drain has in common The job begins identically, whichever the case. Anywhere your vehicle stands — the pub in the village's car park, a street by Shortlanesend Village Hall, a driveway, a filling station — the van gets there and asks about the liquid, the amount, and if the motor has been run. Your price comes over the phone, ahead of anyone setting off, and the replies shape the job. Then that tank is drained and the system flushed thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not rinse out on its own. Last are the filter, cleaned or replaced if necessary; fresh diesel; and a check of your vehicle. If the motor has not run, the majority of jobs take about half an hour once we are there. Our engineers fire it up last. Our check that it runs properly on fresh diesel comes before our engineers head off. The whole job is done where the car is, and if it is noticed quickly, permanent damage is very uncommon. For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, nothing in advance. Dig out your insurance while we're en route: cover for misfuelling comes built into plenty of policies. ## About Shortlanesend Shortlanesend is a village in Cornwall, situated inland at an elevation of 79 metres, approximately 2.1 miles from the city of Truro.
