--- title: AdBlue in a Diesel Tank Mount Pleasant? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/mount-pleasant-durham-dl16-6/ location: Mount Pleasant county: Durham latitude: 54.701790 longitude: -1.581260 service: AdBlue in a Diesel Tank updated: 2026-10-20 --- # What Now? AdBlue in the Diesel Tank in Mount Pleasant One fact matters above all when AdBlue is in a diesel tank, and that is if your motor has been started since. Wherever your vehicle is — Merrington Lane, Mount Pleasant — never start an engine that hasn't been started yet. Keep nothing on, ring 0333 366 0103, and count on a thorough flush plus a drain, done just where the car stands around Mount Pleasant. Pull over the minute it is safe then turn off, if it has been run. The job is bigger, yet the first step is the same. Find the situation below that matches yours, wherever around Durham it happened. ## At the pump in Mount Pleasant: AdBlue in a diesel Imagine it: stood by the petrol pump, holding the bottle, you realise the cap you opened was not the correct one. Anywhere in Mount Pleasant, then — BP, Asda, or somewhere else close by. The upshot: of every spot to find out, the forecourt is the best. The AdBlue is in your tank and nowhere else. Nothing has pulled it in. What to do: don't get back in and start the vehicle to clear the petrol pump. Have the staff to lend a hand pushing it into a bay, hold on to the receipt, then phone us right there. Emptying it right at the petrol pump is fine when it can't be shifted, since the equipment is explosion-proof. ## At home around Mount Pleasant with AdBlue in the diesel tank On the dash, a warning had been lit all week. Only by the recycling, the empty container in your hand, did you glance back at the cap you'd opened on the drive. Homes just off North Road are hit as often as anywhere else. What it means: if you haven't driven since, this is almost as good as the forecourt. As it is unable to mix, AdBlue settles to the base in that tank and waits. One night standing changes none of that. Next: keys indoors, so no one takes your car anywhere first thing. Then, ring. Low Spennymoor or Mount Pleasant: whichever your driveway sits, that is where it is cleared. The pumping kit works quietly enough that it won't wake the neighbours at night. ## Drove off with AdBlue in a diesel around Mount Pleasant? A mile or two after filling up, your motor began misbehaving: rough running, smoke, less power, lights on the dash. Half Moon Lane, say, or the way to Durham — a trip of under 10 miles. Put simply: the AdBlue has been pulled into the fuel system. The injection pump and each injector get it as well on a bigger trip, once your filter and pipework have had it. More driving, more starts: deeper it travels. Next: pick a sensible place, pull in, and turn your engine off. On the A1(M), under 3 miles from Mount Pleasant, that means the next exit, not the services further on. Restarting it to check achieves nothing — AdBlue never clears on its own. Roughly what distance had it gone? Tell us as you phone. ## Hire, lease or company car with AdBlue in the wrong tank You've only driven the car for days. On your own vehicle, AdBlue is missing or elsewhere. On this one, the cap is just next to your diesel inlet — news to you. It can happen to anyone, anywhere in Durham. What it means: the same as the scenarios above, depending on whether it has run, with one more step. Many hire and fleet agreements require the owner's sign-off for work. Next: phone the hire company or the fleet manager first, then us — sorting it before our arrival is quicker. Leave the car switched off as the answer comes, even if you are parked outside Bishop Auckland or near Durham County Council. ## AdBlue in the diesel tank? Not sure, around Mount Pleasant Now and then, "I think so" is all you can truthfully say. The bottle is lighter than it should be, there is a faint smell of ammonia round the filler, and you cannot remember which cap you took off. The gates of North Park Primary School in a rush, say, or someone's drive over in Tudhoe. Meaning? Spills around the inlet don't touch your motor at all. A diesel tank with AdBlue in it is another matter. If there is AdBlue in your tank, turning on the car will pull it in, and it would not tell you which either. Take it that it was put in, and don't turn your key. Checking a tank that turns out free of AdBlue beats emptying one after it has been run — so phone and describe to us what you saw. ## Every AdBlue drain around Mount Pleasant shares these steps Whichever situation you are in, this job starts the same way. Wherever your vehicle stands — The Olive Grove's car park, a street by Mount Pleasant Independent Methodist Church, a drive, a filling station — our van gets there and asks for the liquid, the amount, and whether your engine has turned over. Replies shape the job; the price follows by phone while no one has left yet. Emptying that tank comes first, then a careful flush — more vital after urea than after petrol, because crystals and corrosion will not go by themselves, no matter how long it sits. Last are your filter, cleaned or renewed if necessary; fresh diesel; and a check of the car. Where the engine has not been started, allow about half an hour once we arrive, in most cases. The last step is starting the engine. We make sure it runs properly on new diesel before leaving. When it is noticed quickly, the vehicle very seldom has lasting damage, and the whole job happens where it is. Paying comes that day, never upfront. For the insurer, there is a VAT invoice plus a report from the engineer. Worth knowing: many insurers include misfuelling cover, so a check of your policy while you wait pays. ## About Mount Pleasant itself Mount Pleasant is a suburban area located inland in County Durham, approximately 5.3 miles from the city of Durham.
