--- title: AdBlue in a Diesel Tank St Dominick: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/st-dominick-cornwall/ location: St Dominick county: Cornwall latitude: 50.488240 longitude: -4.257960 service: AdBlue in a Diesel Tank updated: 2026-10-12 --- # What Now? AdBlue in the Diesel Tank in St Dominick Has your engine turned over since the AdBlue was put in? That single question settles almost everything else from here. If it hasn't, keep it that way, whether the vehicle is around St Dominick itself or out in Clampits. Ring 0333 366 0103 with your ignition and motor both off. In St Dominick, that is typically emptied and flushed where it stands. Where the engine has been run, pull in somewhere safe straight away, then turn the vehicle off. The job is bigger, but the first stage is the same. Further down: the situations our technicians meet, anywhere around Cornwall. Pick yours. ## AdBlue in a diesel on a St Dominick forecourt Picture it: stood by the petrol pump, holding the bottle, you spot the cap you took off wasn't the right one. Perhaps you're at the Gulf, maybe at the Tesco, perhaps somewhere else around St Dominick. In short: there is no better place to be to spot it. The AdBlue is in that tank and nowhere else. Nothing has drawn it in. What to do: don't get back in and crank it to clear the petrol pump. Ask the staff to help you roll your car into a parking space, keep the receipt or the bottle, then call us from the forecourt. Emptying it there at the petrol pump is fine when it cannot be moved, since the equipment is explosion-proof. ## AdBlue in the diesel tank on a St Dominick drive? On your dash, a reminder had been lit all week. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look again at the cap. Drives close to Baber Close see it as much as anywhere. The upshot: zero miles since leaves it nearly equal to spotting it at the petrol pump. Diesel and AdBlue keep apart: the AdBlue drops to the floor of the tank and remains put, however long the night. Next: keys indoors, so no one drives the car anywhere first thing. After that, phone. Cross or St Dominick: whichever your driveway is, that's where it is emptied. Even at night, our pumps are quiet enough for a driveway. ## St Dominick: set off with AdBlue in a diesel? A mile or two beyond topping up, the engine started misbehaving: roughness, smoke, less power, lights on the dash. Somewhere along Peppers Court or on the road towards Plymouth — under 10 miles away. Meaning? Your fuel pump has taken the AdBlue in. Through the filter, along the lines, and — the further the mileage — on into the high-pressure pump and each injector. Each mile and each restart takes it further. Stop safely — that's the next step — then turn it off. On the M5, under 50 miles from St Dominick, that means the next exit, not the services further on. Don't restart it to see if it has cleared; it will not have. Roughly how far did it gone? Say so as you call. ## AdBlue in the wrong tank: hire, lease and company cars It's a vehicle you have had for a week. The AdBlue filler sits right beside the diesel filler, which you didn't know, because your own car either has no AdBlue or keeps it somewhere else. Anywhere you happen to be across Cornwall, every motorist could be caught. What it means: the same as the situations above, depending on whether it has run, with one more stage. Work on the vehicle frequently requires the owner's approval under rental or company terms. What to do: ring the hire firm or your fleet manager first, then us. That is faster settled before our technicians arrive than after. If you're stuck in the car park outside Calstock, or by St Dominic, while you wait for an answer, leave the car off. ## Unsure about AdBlue in your diesel tank in St Dominick? Sometimes the honest answer is "I think so". A faint ammonia-like smell hangs around your filler, the bottle seems too light, and which cap came off is hard to recall. A hurried top-up by the gates of St Dominic CofE Primary School, or a visit to a friend in Bohetherick: both fit. The point: the engine isn't hurt by a little AdBlue splashed on the outside. In the diesel tank, by contrast, AdBlue damages it. You can't tell which by turning the key, and doing so would pull in any AdBlue that is in the tank. What to do: treat it as if it got in. Do not start the car. Inspecting a tank that turns out free of AdBlue beats emptying one after it's been run — so ring and describe to us what you saw. ## St Dominick: what each AdBlue drain has in common Every case has the same start to the job. Forecourt, drive, Who'd Have Thought It Inn's car park or a road beside Round at Berry Farm — our van comes to your car, and three questions come next: what fluid, which amount, and whether it has run. Those replies decide the work, and you get the price by phone, before anyone sets off. Draining the tank comes next, followed by a full flush — more vital with urea than with petrol, because crystals and corrosion won't go on their own, no matter how long it sits. Then is the filter — flushed, or swapped where necessary — followed by fresh diesel, and a test of the vehicle. Never started? In that case roughly half an hour once we are there covers most jobs. We fire it up last. Our check that it runs properly on clean diesel comes before we go. If it's noticed early, the car very seldom has long-term damage, and the whole job happens where it is. Payment comes that day, never upfront. For the insurer, you get a VAT invoice plus a report from the engineer. Check your insurance while we arrive: misfuelling cover is included in plenty of policies. ## About St Dominick and where it is St Dominick is a small village in Cornwall, situated inland at an elevation of 119 metres, and is located near the villages of Cross, Burraton, and Ashton.
