--- title: Blowinghouse: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/blowinghouse-cornwall/ location: Blowinghouse county: Cornwall latitude: 50.230110 longitude: -5.246570 service: AdBlue in a Diesel Tank updated: 2026-10-24 --- # AdBlue in the Diesel Tank in Blowinghouse, and What to Do Next What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the motor has run since it was put in. Over in Illogan Highway or right around Blowinghouse, an unrun engine should stay unrun. Phone 0333 366 0103 with the key and motor both off. In Blowinghouse, that is typically drained and cleaned where it stands. If it has run, stop as soon as it is safe and switch off. Stage one stays the same, even though the job is bigger. Wherever in Cornwall it took place, one of the cases below matches yours. ## Blowinghouse forecourt: AdBlue in a diesel at the pump You are 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. Possibly you are at the Texaco, perhaps at the Tesco, possibly somewhere else around Blowinghouse. The upshot: of all places to find out, the forecourt is the best. The AdBlue is in your tank and nowhere else. Nothing has drawn it in. Next: avoid the temptation to start it just to free up the pump. Ask the attendants to help you push the vehicle into a parking spot, keep the till receipt or the bottle, then ring us from the forecourt. Our equipment is explosion-proof and fine on a busy forecourt, and so a vehicle that can't be pushed clear is drained right at the petrol pump. ## At home in Blowinghouse with AdBlue in the diesel tank The warning light had been on for days. Only by the recycling, the empty container in hand, did you glance back at the cap you'd used on the driveway. It takes place on driveways just off Barncoose Avenue as regularly as anywhere. What it means: if you have not driven since, this is nearly as good as the forecourt. Diesel and AdBlue keep apart: the AdBlue settles to the floor of your tank and stays there, however long it waits. Next: prevent any early-morning drive by keeping your keys in the house, then phone us. Your drive is where it is emptied, be it around Blowinghouse or Carn Brea Village. Even at night, our pumps are quiet enough for a residential street. ## AdBlue in a diesel and already driving around Blowinghouse? You filled up, set off, and a mile or two later the engine began to run roughly, smoke, lose power or light up the dashboard. Lower Barncoose, say, or the route to Truro — a run of under 10 miles. The point: the system has drawn AdBlue through by now. Mileage decides how deep it goes: filter and lines to begin with, then the injection pump and each injector. Each restart, like every mile, carries it deeper. Stop safely — that is the first step — then turn it off. Service stations farther on can wait: from the M5, over 50 miles out of Blowinghouse, take the first junction. Don't restart the car to see if it has cleared; it will not have. Roughly what distance had it go? Say so as you call. ## AdBlue in the wrong tank: hire, lease and company vehicles You've only driven this car a week. Unbeknown to you, the AdBlue and diesel inlets are next to each other here — not like your own car, which has none or stores it elsewhere. Anywhere you happen to be in Cornwall, any driver could slip up. In short: one extra step on top of the situations above, which turn on if it's run. Any work on the car often needs the owner's approval under rental or company terms. What to do: call the hire firm or your fleet manager first, then us. That is quicker settled before our technicians arrive than after. Stuck by Former Methodist Church or at Redruth until the firm replies, the car stays turned off the whole time. ## Unsure about AdBlue in the diesel tank in Blowinghouse? Sometimes the fair answer is "I think so". What cap came off, you can't recall; meanwhile the bottle weighs less than it ought to, and ammonia hangs by your filler. It might have been at a friend's driveway in Tolgus Mount, or in a rush by Treloweth Community Primary School at the school run. The upshot: your motor isn't harmed by some AdBlue spilled on the outside. A diesel tank with AdBlue in it is another matter. Any AdBlue in that tank will be sucked in by starting your car, and the start would not settle which it is in any case. Do this: act as though it did, and don't start your engine. Checking a tank that turns out clean is better than draining one after it has been run — so ring and tell us what you noticed. ## Each AdBlue drain around Blowinghouse shares these steps The job opens the same way, whatever your situation. We come to the vehicle, whether it is at a forecourt, a driveway, the car park at Tricky Dickies or a side street close to Carn Brea Village Hall, and ask three things: what got in, roughly how much, and whether your engine has run. Answers set the job; the price comes on the call while no one has left yet. Draining that tank comes first, followed by a careful flush — more vital with urea than with petrol, because crystals and corrosion won't clear by themselves, however long it sits. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Where your engine hasn't run, expect roughly half an hour on site, for most cases. We start the car last. Before our engineers head off, it is checked to confirm it runs correctly on fresh diesel. If it's noticed quickly, the car very seldom has permanent damage, and the entire job takes place where it is. For your insurer: an engineer's report and the VAT invoice. For you: payment that day, nothing in advance. Many insurance policies cover misfuelling, so check yours as we head over. ## About Blowinghouse, briefly Blowinghouse is a suburban area in Cornwall, situated inland at an elevation of 104 metres, approximately 8.9 miles from Truro.
