--- title: Foundry: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/foundry-cornwall/ location: Foundry county: Cornwall latitude: 50.184370 longitude: -5.421010 service: AdBlue in a Diesel Tank updated: 2026-10-26 --- # AdBlue in the Diesel Tank in Foundry: What Now? One fact counts above all once AdBlue is in a diesel tank, and that is whether your engine has run since. Over in Phillack or here around Foundry, an unrun engine must stay that way. Leave your motor and your ignition off then phone 0333 366 0103; it is usually a drain and a thorough flush, done where the car is in Foundry. If it has run, stop as soon as it is safe then switch off. A bigger job, yes, yet the same opening step. Match what happened to one of the list below, wherever around Cornwall you are. ## AdBlue in a diesel on a Foundry forecourt Just now, nozzle still in hand, it dawns on you that the cap you opened was the wrong one, right at the pump. It might be the Central Garage, or the another forecourt nearby, or a different station around Foundry. What it means: this is the best spot to find out. Nothing has drawn it in, and so the AdBlue stays just in your tank. Next: resist the urge to start it just to move away from the petrol pump. Phone us from the forecourt once your car sits in a space — the attendants will lend a hand to roll it — and save the bottle. Can't move the car by the pump? Our explosion-proof equipment keeps a busy forecourt safe, and so we can drain it where it is. ## AdBlue in your diesel tank at home in Foundry On your dash, a warning had shown for days. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look again at the cap. Right off Chapel Terrace is no less likely from anywhere. The point: zero miles since leaves this nearly as good to spotting it at the pump. Diesel and AdBlue keep apart: the AdBlue drops to the base of that tank and stays put, however long it waits. Next: prevent an early move by keeping the keys in the house, then phone us. Your driveway is where it is emptied, whether in Foundry or Hayle. Even at night, the pumps stay quiet enough for a driveway. ## Drove off with AdBlue in a diesel in Foundry? Lumpy running, smoke, falling power or a lit dashboard started a mile or two beyond the fill. Perhaps it was on Station Hill, maybe on the way out towards Truro, under 25 miles away. Meaning? Your pump has taken the AdBlue in. It's been through the filter and your lines and, the further you went, into the high-pressure pump and the fuel injectors. It goes further with every extra mile covered and every restart. What to do: pull over where it is safe to do so and switch off. Exit at the first junction — not the services beyond — if you are on the M5, over 50 miles from Foundry. Do not restart the car to see if it has cleared; it will not have. Call us and say how far you drove. ## AdBlue in the wrong tank: hire, lease and company cars Seven days ago, the car was unknown to you. Your own vehicle either does without AdBlue or keeps it elsewhere, and so nothing warned you the AdBlue inlet was just beside your diesel. It can happen to anyone, anywhere in Cornwall. What it means: the same as the scenarios above, depending on whether it's run, with one more step. Any work on the car often needs the owner's go-ahead under rental or fleet terms. Next: phone the rental company or your fleet manager first, and then us — settling it before we arrive is faster. Leave the vehicle switched off while the answer arrives, whether you're waiting at Hayle or near Rick Rescorla. ## Unsure about AdBlue in your diesel tank in Foundry? "I think so" is often as honest answer there is. A faint ammonia-like smell lingers near your filler, the bottle seems too light, and the cap you took off is hard to recall. Maybe at a friend's drive in The Towans, or in a rush by Penpol School on the school run. What it means: a little spilled about your filler does no damage to the motor. A diesel tank with AdBlue in it is another matter. Any AdBlue in your tank will be sucked in by turning on the car, and the start would not settle which it is in any case. Do this: behave as if it got in, and don't start your engine. Describe what you noticed on the phone. A clear tank checked is a happier result than an already-run one emptied. ## What each AdBlue drain in Foundry has in common Whichever scenario you are in, this job starts the same way. Forecourt, driveway, Royal Standard's car park or a street beside Harvey's Foundry — the van reaches your car, and three questions follow: what liquid, which quantity, and whether it has run. Those answers settle the work, and you hear the price on the phone, before anyone heads out. A thorough flush comes after the drain. With petrol it is routine; with AdBlue it is essential, because deposits build up and certain metals are attacked, and neither washes away unaided. Finally are the fuel filter, flushed or renewed if necessary; clean diesel; and a test of the vehicle. Not started? Then about half an hour on site is most jobs. Last, we start the engine. Before our technicians head off, it is tested to make sure it runs properly on fresh diesel. Our technicians do the entire job where the vehicle is, and long-term damage is very unusual when it has been caught soon. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, nothing in advance. Plenty of policies include misfuelling, and so look at yours while the van travels. ## About Foundry, briefly Foundry is a small suburban area in Cornwall, situated near the coast and close to the towns of Hayle and Copperhouse. Foundry lies at a low elevation of around 7 metres, and its proximity to the sea has influenced its development. Foundry is characterized by its predominantly terraced housing stock, which reflects its history of growth as a residential area. Foundry is located near several notable places, including Trelissick, and is around 17 miles from the city of Truro. ## AdBlue drains in Foundry, and across Cornwall too Foundry is a residential suburb, and the same teams that cover it work the towns around it too, Copperhouse and Trelissick among them, across the TR postcode area. The location is clearest from a postcode beginning TR27 4. Whether the vehicle is on a lay-by on the way to Ellis Park or in a car park in the middle of Foundry, it doesn't need to shift. Our technicians drain the vehicle where it stands. Assuming doesn't help beside Carnsew Art Gallery, close to a county line or somewhere awkward to pin down; ring and ask. ## Your situation, summed up Not run yet: keep the car off and call. Run already: stop, switch down, ring 0333 366 0103. Petrol in Diesel handles the remainder, in Foundry or anywhere in Cornwall.
