AdBlue in the Diesel Tank in Rundlestone What to do about AdBlue in a diesel tank depends on one thing more than any other: if your engine has been run since it got in. Anywhere the car stands — Peat Cot, Rundlestone — don't run an engine that hasn't run yet. Keep nothing on, ring 0333 366 0103, then expect a proper flush after a drain, carried out just where your vehicle stands around Rundlestone. If it's run, stop as soon as it is safe then switch off. A bigger job, then, but the same opening step. Further down: the cases our engineers meet, wherever across Devon. Choose yours. ## Rundlestone forecourt: AdBlue in a diesel at the pump Imagine it: stood by the pump, gripping the bottle, you spot the cap you took off was not the right one. Anywhere in Rundlestone, then — the nearest petrol station, another forecourt nearby, or anywhere else close by. In short: there is no better place to be to spot it. The AdBlue is in the tank and nowhere else. Nothing has pulled it in. Clearing the petrol pump is no reason to start it — and so do not get back in. Ask the staff to help you roll the car into a parking space, keep the till receipt or the bottle, and phone us from the forecourt. Emptying it there at the petrol pump is possible if it cannot be shifted, because the equipment is explosion-proof. ## At home around Rundlestone with AdBlue in your diesel tank For days the dash had been nagging you. Picked up a bottle, tipped it in at home, binned the empty — and at that point checked the cap a second time, after the fact. Driveways near Tavistock Road get it as much as anywhere. Put simply: if the car has not moved since, it's nearly equal to spotting it at the forecourt. At the bottom of that tank sits exactly where AdBlue stays, because it won't mix with diesel — and a night passing makes no difference. Next: the keys in the house, and so no one takes your vehicle off first thing. After that, ring. We drain the car on your driveway, whether that's in Rundlestone or out in Princetown. The pumps are quiet enough to use outside a house after dark. ## On the road around Rundlestone with AdBlue in a diesel A mile or two after filling up, the motor began playing up: rough running, smoke, less power, lights on the dash. Possibly it was on Beech Crescent, perhaps on the way out towards Plymouth, under 15 miles away. What it means: the system has sucked the AdBlue in. Mileage sets how deep it gets: filter and pipework first, then the high-pressure pump and every injector. It goes deeper with each extra mile covered and every restart. Do this: stop anywhere safe, then turn your motor off. On the M5, under 25 miles from Rundlestone, that means the next junction, not the services further on. It won't have cleared, and so there is no point starting it again to find out. Phone us and say how far you went. ## AdBlue in the wrong tank: hire, lease and company vehicles A week back, it was unknown to you. On your own vehicle, AdBlue is missing or elsewhere. On this one, its inlet is just by your diesel cap — news to you. Across Devon, nobody is immune. Meaning? Whatever case above applies here — run or not — plus one further step. Many hire and fleet agreements need the owner's sign-off for work. What to do: ring the hire firm or your fleet manager first, then us. That is quicker settled before we get there than after. Stuck near Dartmoor Prison Museum or outside Gunnislake till the firm answers, the vehicle stays switched off throughout. ## AdBlue in the diesel tank? Not sure, around Rundlestone Truthfully, the only answer might be that you think so. The bottle is lighter than it should be, there is a faint smell of ammonia around the filler, and you cannot remember which cap you took off. The gates of Princetown Community Primary School in a hurry, perhaps, or a friend's driveway over in Sampford Spiney. What it means: a little spilled around the filler does no harm to your engine. AdBlue inside your diesel tank does. Firing up your car won't tell you which, and if there is AdBlue in your tank it will pull it in. Your move: act as if it did, and don't start your motor. Ring us and describe what you saw; we'd rather check a tank that turns out clean than drain one that has already been run. ## Rundlestone: what each AdBlue drain has in common The work opens the same way, whatever the situation. We come to your car, whether it is on a forecourt, a drive, the car park at the pub in the village or a side street near American and French Prisoners of War memorial garden, and ask three things: what was put in, about how much, and whether your motor has run. Those replies determine the work, and you hear our quote on the phone, before anybody sets off. A thorough flush comes after the drain. With petrol it is routine; with AdBlue it's crucial, because deposits form and certain metals corrode, and none of that washes away unaided. Fresh diesel is put in once the fuel filter has been flushed or changed, and the car is finally tested. The majority of unrun cars are a half-hour job from the moment we arrive. Starting the car comes last. We make sure it runs correctly on fresh diesel before leaving. We do the entire job where your car is, and long-term damage is very unusual if it has been noticed soon. Payment is on the day, never in advance. For your insurer, there is a VAT invoice plus a written report from the engineer. Many insurance policies include misfuelling, and so look at yours as we head over. ## About Rundlestone Rundlestone is a rural locality in Devon, situated inland at an elevation of 448 metres, approximately 14 miles north of Plymouth.
