--- title: What Now? AdBlue in a Diesel Tank High Throston canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/high-throston-durham/ location: High Throston county: Durham latitude: 54.694210 longitude: -1.249060 service: AdBlue in a Diesel Tank updated: 2026-10-07 --- # What Now? AdBlue in the Diesel Tank in High Throston 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. Wherever the vehicle stands — Hart, High Throston — don't start an engine that hasn't run yet. Normally that means draining and thoroughly cleaning it right there in High Throston — and so keep your ignition and engine off then ring 0333 366 0103. Stop the minute you safely can and turn off, if it has been run. The job is bigger, but the first step is the same. Wherever across Durham it took place, one of the cases below matches yours. ## At the petrol pump in High Throston: AdBlue in a diesel Picture it: standing by the pump, gripping the bottle, you spot the cap you took off wasn't the correct one. Whether Esso, Morrisons or somewhere else in High Throston, the case is the same. The point: of all places to notice, this is the best. The AdBlue is inside the tank and nowhere else. Nothing has drawn it in. Your move: keep out of the car, however much the queue needs freeing. Three things: a push into a bay with the staff helping, the bottle saved, and a ring to us from where you stand. Stuck by the pump? Explosion-proof equipment keeps a live forecourt safe, so it can be drained in place. ## AdBlue in your diesel tank at home in High Throston The warning light had been on for days. Only at the recycling bin, the empty container in hand, did you look back at the cap you had used at the drive. Right off Nookston Close is not different from any other place. The point: no driving since leaves this almost as good to spotting it at the pump. At the bottom of that tank sits where AdBlue stays, since it will not blend with diesel — and a night going by changes nothing of the difference. Next: the keys indoors, and so no one drives the car anywhere first thing. Then, phone. Out in Throston Grange Estate or right here around High Throston, the drain is done at your drive. The pumps are quiet enough to use outside a house at night. ## On the road in High Throston with AdBlue in a diesel You filled up, set off, and a mile or two later your motor began to run roughly, smoke, lose power or light up the dashboard. Somewhere on Daleston Close or else heading towards Durham — under 15 miles away. In short: the AdBlue has been pulled into the system. Through the filter, along the pipework, and — the further the mileage — deeper into the high-pressure pump and every injector. It travels deeper with each extra mile covered and each restart. What to do: pull over where it is safe then switch off. On the A1(M), under 10 miles from High Throston, that means the next junction, not the services further on. No trial restarts: clearing itself isn't something AdBlue will do. About how far had it gone? Say so when you phone. ## Hire, lease or company car with AdBlue in the wrong tank You have had this car barely a week. On your own vehicle, AdBlue is absent or somewhere else. On this one, its inlet is right next to the diesel inlet — news to you. Anywhere you happen to be around Durham, every motorist can slip up. The point: exactly as above, divided by whether it ran, only with one added step. The owner frequently needs to sign off the work, under many hire and fleet contracts. Do this: hire firm or your fleet manager first, us second, because sorting it early cuts time. Stranded near Throston Grange Library or outside Hartlepool till the firm answers, your car stays turned off throughout. ## High Throston: unsure whether it was AdBlue in the diesel tank? "I think so" is sometimes the most honest answer there is. Lighter, the bottle; a hint of ammonia round the filler; no clear recollection of which cap. Sound familiar? Maybe on a friend's driveway in Dyke House, or in a rush outside Throston Primary School on the school run. Put simply: a spill near the filler leaves your motor no harm. In your diesel tank, by contrast, AdBlue damages it. If there is AdBlue in that tank, firing up your car will pull it in, and it would not tell you which either. What to do: treat it as if it was put in. Do not crank it. Ring us and explain what you saw; we'd rather check a tank that turns out free of AdBlue than drain one that has already been run. ## What each AdBlue drain in High Throston has in common The work begins identically, whichever your case. Forecourt, driveway, The Golden Lion's car park or a road beside Low Throston deserted medieval village — the van comes to your car, and three questions come next: which liquid, which amount, and whether it ran. Your price is given over the phone, before a van leaves, and the answers shape the job. Then that tank is emptied and the system cleaned thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not rinse out on its own. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. The majority of unrun cars are a half-hour visit after the moment we turn up. Our engineers fire it up last. Before our engineers head off, it's tested to confirm it runs properly on new diesel. Our technicians do the whole job where the car is, and permanent damage is very unusual when it has been caught quickly. For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, nothing in advance. It is worth remembering: lots of insurers offer misfuelling cover, so a check of your documents while we travel pays. ## About High Throston itself High Throston is a coastal locality in County Durham, situated near the city of Durham and overlooking the North Sea.
