--- title: What Now? AdBlue in a Diesel Tank Clayhidon canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/clayhidon-devon/ location: Clayhidon county: Devon latitude: 50.933150 longitude: -3.194620 service: AdBlue in a Diesel Tank updated: 2026-10-15 --- # AdBlue in the Diesel Tank in Clayhidon, and What to Do Next One fact matters above all when AdBlue is in a diesel tank, and it is if your motor has been started since. Not started yet? Then keep the car that way, wherever your vehicle sits — Clayhidon or Ashculme. Ring 0333 366 0103 with the key and engine both off. In Clayhidon, that is typically drained and cleaned where it stands. If it has run, stop as soon as it is safe then switch off. It is a larger job, though stage one doesn't change. Match your case to one of the ones below, anywhere in Devon you happen to be. ## Clayhidon forecourt: AdBlue in a diesel at the pump The cap you unscrewed was the wrong one — and you only spot it as you are standing at the pump, bottle or the nozzle in hand. Perhaps you're at the Monument Fuels, maybe at the another forecourt nearby, perhaps somewhere else around Clayhidon. In short: there is no better spot exists to spot it. The AdBlue is in the tank and nowhere else. Nothing has pulled it in. What to do: don't get back in and crank it to clear the petrol pump. Ask the attendants to help you roll your car into a parking spot, keep the till receipt or the bottle, then call us from the forecourt. If it cannot be shifted, it can be drained at the pump: the equipment is explosion-proof and safe on a working forecourt. ## AdBlue in the diesel tank at home around Clayhidon Several days had passed with the warning light on. Only at the recycling bin, the empty container in hand, did you glance back at the cap you had used at the drive. It takes place on driveways just off Black Lane as frequently as anywhere. Meaning? Provided the vehicle hasn't moved since, it's close to the forecourt case. AdBlue doesn't mix with diesel; it sinks to the bottom of your tank and waits there. Overnight does not change that. Keep the keys indoors tonight — otherwise someone may drive it off first thing — and phone us. Rosemary Lane or Clayhidon: wherever your driveway sits, that is where it is cleared. Late-night drains beside a house are no problem: the pumps are low-noise. ## AdBlue in a diesel and already driving around Clayhidon? You filled up, set off, and a mile or two later the motor began to run roughly, smoke, lose power or light up the dashboard. Anywhere on Gray's Lane or else on the road to Exeter — under 25 miles away. In short: the AdBlue has been sucked into the fuel system. The high-pressure pump and every injector get it too on a bigger run, after the filter and pipework have had it. It travels further with every mile covered and every restart. What to do: pull over where it is safe then switch off. On the M5, under 3 miles from Clayhidon, that means the next exit, not the services further on. Do not restart it to see if it has cleared; it will not have. Ring us and say how far you went. ## AdBlue in the wrong tank: hire, lease and company cars You have just had this vehicle for days. On your own car, AdBlue is absent or somewhere else. On this one, the cap is just by the diesel cap — news to you. Wherever you happen to be around Devon, any driver could be caught. Meaning? Whatever applies above applies too — run or not — plus one further step. Any work on the car often requires the owner's approval under rental or company terms. Do this: hire firm or your fleet manager first, us next, since settling it beforehand cuts time. Leave the car off while the reply arrives, even if you're waiting at Tiverton Parkway or near St Andrew's. ## AdBlue in the diesel tank? Not sure, in Clayhidon "I think so" is sometimes the most honest as it gets. Too light, that bottle; a hint of ammonia round the filler; a hazy memory of which cap. Look familiar? Maybe it happened in a hurry at the school gates at Hemyock Primary School, or on a friend's drive in Carlingwark. The point: your motor is not harmed by some AdBlue spilled on the filler. AdBlue inside the diesel tank does. Any AdBlue in your tank would be pulled in by firing up the car, and the start wouldn't settle which it is in any case. Do this: behave as though it got in, and don't start the motor. Describe what you noticed on the phone. A clean tank looked at counts as a better outcome than an already-run one drained. ## Each AdBlue drain in Clayhidon shares these steps Every situation has the same opening to the work. We come to the car, whether it is at a forecourt, a driveway, the car park outside Half Moon Inn or a side street near Clayhidon Village Hall, and ask three things: what got in, about how much, and whether your motor has been run. Answers set the work; the price follows by phone while nobody has set off yet. AdBlue crystallises and eats at some metals used in fuel systems, so it does not wash out on its own; that's why a full flush, after this drain, counts much more here than with petrol. The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. The majority of unrun cars are a half-hour job from the moment our technicians turn up. Finally, our technicians fire it up. With new diesel in, it runs while our technicians confirm it's running correctly, and then we leave. When it is caught quickly, the vehicle very seldom has long-term damage, and the whole job takes place where it is. Payment comes on the day, never in advance. For your insurer, there is a VAT invoice and a report from the engineer. Many policies cover misfuelling, so look at yours while the van travels. ## About Clayhidon, for a moment Clayhidon is a small hamlet in inland Devon, situated at an elevation of 232 metres, approximately 20.7 miles from Exeter.
