--- title: AdBlue in a Diesel Tank Cottam: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/cottam-east-riding-of-yorkshire/ location: Cottam county: East Riding of Yorkshire latitude: 54.069220 longitude: -0.481280 service: AdBlue in a Diesel Tank updated: 2026-10-25 --- # Cottam: AdBlue in the Diesel Tank? Find Your Situation What to do about AdBlue in a diesel tank comes down to one thing more than any other: if your motor has been run since it went in. If it has not, keep it that way, whether your car is in Cottam itself or out in Great Kendale. Usually that is emptying and thoroughly cleaning it on the spot in Cottam — so keep your key and engine off then call 0333 366 0103. When your engine has been run, stop somewhere safe first, then turn the vehicle off. The job is bigger, but the first stage is the same. Compare your case to a situation from the list below, anywhere around East Riding of Yorkshire you are. ## At the petrol pump around Cottam: AdBlue in a diesel Only now, nozzle yet in hand, you realise that the cap you took off was the wrong one, there at the pump. Whether G Boyes, PMH or somewhere else around Cottam, the case is identical. The upshot: of all places to notice, the forecourt is the best. The AdBlue is in that tank and nowhere else. Nothing has pulled it in. Do this: stay out of the driver's seat, even if the pump wants freeing. A few things: a push into a space with the staff helping, the receipt saved, and a call to us from the forecourt. Draining it right at the petrol pump is possible when it can't be moved, since the equipment is explosion-proof. ## At home in Cottam with AdBlue in your diesel tank The warning light had been on 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 once more at the cap. Right off Cottam Lane is no different from any other place. In short: if the car has not been driven since, it's almost as good as finding out at the pump. As it is unable to mix, AdBlue drops low inside that tank and stays. One night parked changes nothing. What to do: leave your keys inside the house so nobody moves the vehicle in the morning. Then ring. Our engineers drain it on your driveway, whether that's around Cottam or out in Cottam Warren. The pumps are quiet enough to use outside a house after dark. ## Set off with AdBlue in a diesel in Cottam? Rough running, smoke, falling power or a glowing dashboard arrived a mile or two after the fill. It might have been driving to Kingston upon Hull, under 25 miles away, or simply down Scarborough Road. In short: the AdBlue has been sucked through the system. The injection pump and every injector get it as well on a longer trip, once the fuel filter and pipework have had it. It travels further with every extra mile driven and every restart. Your move: pull up anywhere sensible, then switch your engine off. Leave by the first junction — not the services further along — if you are on the Petuaria Way, under 25 miles from Cottam. Starting it again to test gets nothing — AdBlue doesn't clear itself. Phone, and say what distance your vehicle was driven. ## AdBlue in the wrong tank: hire, lease and company cars It is a car you have had for a week. The AdBlue filler sits right next to the diesel one, which you did not know, since your own motor either has no AdBlue or keeps it somewhere else. Across East Riding of Yorkshire, no one is safe from it. Meaning? Whatever applies above applies here — run or not — and one extra stage. Plenty of hire and company contracts require the owner's approval for work. What to do: ring the hire firm or your fleet manager first, then us. That is faster settled before our technicians turn up than after. If you're stuck in the car park at Driffield, or by The Church Rooms, whilst you wait for an answer, leave the car off. ## AdBlue in the diesel tank? Not sure, in Cottam Occasionally the fair answer is "I think so". What cap was taken off, you can't say; meanwhile the bottle weighs lighter than it ought to, and a whiff of ammonia hangs by the filler. It might have been at a friend's drive in Pockthorpe, or rushing outside Garton-on-the-Wolds Church of England Voluntary Controlled Primary School at the school run. The upshot: the motor is not hurt by some AdBlue splashed on the outside. A diesel tank with AdBlue in it is another story. Firing up your car cannot tell you which, and if there is AdBlue in the tank it will suck it in. What to do: treat it as if it got in. Don't start it. Checking a tank that turns out clean beats draining one after it has been run — so phone then tell us what you noticed. ## What each AdBlue drain around Cottam has in common The job opens identically, whatever the situation. Three questions come when our engineers reach the car — at a filling station, a drive, a road beside St. Peter's or the car park outside the pub in the village: the fluid, the quantity, and whether the motor has been started. On the phone, ahead of anything else, you are told our quote, and those answers decide the job too. A thorough flush comes after the drain. With petrol it's standard; with AdBlue it is essential, because deposits build up and certain metals corrode, and neither rinses out unaided. Clean diesel goes in after the fuel filter is flushed or replaced, and the car is finally checked. Not started? Then roughly half an hour on site covers most jobs. The last step is firing it up. Before our engineers leave, it's checked to make sure it runs correctly on new diesel. We do the whole job where the car is, and lasting damage is very unusual if it has been caught quickly. Nothing is paid upfront, payment is made on the day, and you receive what your insurer asks for: an engineer report plus a VAT invoice. Worth remembering: lots of insurers include misfuelling cover, and so a check of your documents as we travel pays. ## About Cottam, briefly Cottam is a small locality in the East Riding of Yorkshire, situated inland at an elevation of around 144 metres.
