--- title: Polruan: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/polruan-cornwall/ location: Polruan county: Cornwall latitude: 50.328900 longitude: -4.634150 service: AdBlue in a Diesel Tank updated: 2026-10-19 --- # What Now? AdBlue in the Diesel Tank in Polruan One fact counts most once AdBlue is in a diesel tank, and it is whether your engine has been started since. Wherever the car is — Lescrow, Polruan — don't run a motor that hasn't been started yet. Ring 0333 366 0103 with the ignition and motor still off. Across Polruan, that is typically emptied and flushed on the spot. Pull over the minute you safely can then switch off, if it has been run. The job is bigger, but the first stage is the same. Match your case to one of the list below, wherever around Cornwall you are. ## Polruan forecourt: AdBlue in a diesel at the pump The cap you opened was the wrong one — and you just spot it while you are standing at the petrol pump, bottle or the nozzle in your hand. Be it the nearest petrol station, Gulf or somewhere else in Polruan, the situation is the same. The point: of all places to find out, the forecourt is the best. The AdBlue is inside your tank and nowhere else. Nothing has drawn it in. What to do: don't get back in and crank it to clear the pump. Ask the attendants to help you roll the vehicle into a parking spot, keep your receipt or the bottle, and call us from the forecourt. Can't move the vehicle by the pump? Explosion-proof kit keeps a live forecourt sensible, and so we can drain the car in place. ## AdBlue in your diesel tank on a Polruan drive? For days the dash had been warning you. Only at the recycling bin, the empty bottle in your hand, did you glance back at the cap you had used on the drive. Just off East Street is not less likely from anywhere. What it means: if you haven't driven since, this is nearly as good as the forecourt. Diesel and AdBlue stay apart: the AdBlue settles to the base of your tank and stays there, no matter how long the night. Keep the keys in the house tonight — otherwise a person might drive it off at breakfast — and call us. Fowey or Polruan: wherever your drive sits, that's where it is cleared. Even at night, our pumps stay quiet enough for a driveway. ## On the road around Polruan with AdBlue in a diesel Topped up, drove away, and soon the engine was running roughly, blowing smoke, down on power, or lighting up your dash. Somewhere along Fore Street or else heading to Truro — under 25 miles away. The upshot: the system has drawn AdBlue in by now. Through the filter, through the pipework, and — the more the distance — deeper into the high-pressure pump and every injector. More miles, more starts: deeper it travels. Do this: pull up somewhere sensible, then turn the motor off. On the M5, over 50 miles from Polruan, that means the next junction, not the services further on. Restarting it to test gets nothing — AdBlue doesn't clear on its own. Phone, and say what distance your vehicle was driven. ## A hire or company car with AdBlue in the wrong tank? You've only driven the car for days. The AdBlue filler sits right next to the diesel one, which you did not know, because your own vehicle either has no AdBlue or keeps it somewhere else. Anyone, anywhere across Cornwall, might do the same. Meaning? Whichever case above applies here — run or unrun — and one further step. Work on your vehicle frequently needs the owner's approval under hire or fleet agreements. Settling it before we arrives is quicker, so ring the hire company or your fleet manager, and then us. If you're stuck in the car park outside Par, or by St Saviour's, whilst you wait for an answer, leave the car off. ## Not sure it was AdBlue in your diesel tank, Polruan? Now and then, "I think so" is all anyone can honestly say. The bottle is lighter than it should be, there's a faint smell of ammonia about the filler, and you cannot remember which cap you took off. A rushed stop by the gates of Polruan Primary Academy, or a call to a friend in Mixtow: both fit. The point: your engine isn't hurt by some AdBlue spilled around the filler. Inside the diesel tank, however, AdBlue harms it. You cannot tell which by turning the key, and doing so will pull in any AdBlue that is in that tank. Assume it was put in, and don't start the engine. Ring with what you saw: we would rather find a clean tank than empty one once the engine has been run. ## Polruan: what each AdBlue drain has in common No matter the situation, one start is used. Filling station, drive, The Russell Inn's car park or a street beside St Saviour's Chapel — our van reaches your car, and three questions come next: what liquid, what quantity, and whether it has run. Over the phone, before anything else, you are told our quote, and those answers decide the work too. Emptying your tank comes next, then a full flush — more vital after urea than after petrol, because crystals and corrosion will not go on their own, no matter how long you wait. Finally are the fuel filter, cleaned or replaced if necessary; fresh diesel; and a test of your vehicle. Where your motor has not run, allow about half an hour once we arrive, for most jobs. Our engineers fire it up at the end. With fresh diesel in, it runs while our technicians make sure it is running properly, and then we head off. We do the whole job where the car is, and lasting damage is very rare if it has been caught soon. Nothing is paid upfront, settlement happens on the day, and you get what the insurer asks for: an engineer report and a VAT invoice. Plenty of policies include misfuelling, so check yours while the van travels. ## About Polruan Polruan is a small coastal village in Cornwall, situated on the eastern bank of the Fowey estuary.
