--- title: AdBlue in a Diesel Tank Tarnock: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/tarnock-somerset/ location: Tarnock county: Somerset latitude: 51.269350 longitude: -2.892200 service: AdBlue in a Diesel Tank updated: 2026-10-19 --- # Tarnock: AdBlue in the Diesel Tank? Find Your Situation All of it turns on one fact: if the motor has started after the AdBlue went in — more than anything else. If it hasn't, keep it that way, whether the vehicle is around Tarnock itself or out in Edingworth. Leave your engine and your ignition off then ring 0333 366 0103; it is generally a drain and a thorough flush, done where the vehicle is around Tarnock. Stop the minute it is safe then switch off, if it has already run. The job is bigger, but the first stage is the same. Find the situation below that matches yours, wherever across Somerset it happened. ## Tarnock forecourt: AdBlue in a diesel at the pump You are at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Perhaps you are at the Shell, possibly at the BP Weare, perhaps somewhere else in Tarnock. The point: of every spot to find out, the forecourt is the best. Still inside the tank, with no fuel pulled through: that's where the AdBlue is. Next: avoid the urge to fire it up just to move away from the petrol pump. Three jobs: a push into a bay with the attendants helping, the bottle kept, and a ring to us from the forecourt. Emptying it there at the petrol pump is possible when it cannot be moved, since the equipment is explosion-proof. ## AdBlue in your diesel tank on a Tarnock drive? On your dash, a reminder 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 once more at the cap. It takes place on driveways just off A38 as often as anywhere. The point: zero driving since leaves it almost equal to spotting it at the petrol pump. On the floor of your tank sits where AdBlue stays, because it won't mix with diesel — and a night going by makes no difference. Put your keys in the house overnight — otherwise a person might take it away at breakfast — and call us. Your driveway is where it is drained, whether around Tarnock or Biddisham. Night-time empties outside a house are no problem: the pumps are quiet. ## On the road around Tarnock with AdBlue in a diesel Lumpy running, smoke, lost power or a lit dashboard arrived a short way beyond the top-up. Perhaps it was on Kingsway, possibly on the way out towards Wells, under 15 miles away. Meaning? The fuel pump has sucked the AdBlue up. It's been through your filter and the fuel lines and, the further you went, into your high-pressure pump and the injectors. Each mile and each restart takes it further. Do this: pull up somewhere sensible, then switch your motor off. Leave by the next junction — not the services further along — if you're on the M5, under 3 miles from Tarnock. No test starts: clearing itself isn't something AdBlue will do. Call, saying what distance your car was driven. ## A hire or company car with AdBlue in the wrong tank? You've had the vehicle barely a week. On your own vehicle, AdBlue is absent or elsewhere. On this one, its cap is just by your diesel cap — a surprise to you. It can happen to anyone, anywhere around Somerset. Put simply: one extra step on top of the situations above, and those turn on if it's run. Plenty of rental and company agreements require the owner's approval before repairs. What to do: ring the hire firm or your fleet manager first, then us. That's quicker settled before we get there than after. Hanging on for a reply in the car park at Highbridge & Burnham, or beside St John the Baptist? Leave the engine off meanwhile. ## Not sure it was AdBlue in your diesel tank, Tarnock? "I think so" is often as honest as it gets. The bottle is lighter than it should be, there's a faint smell of ammonia round the filler, and you can't remember which cap you took off. Possibly it happened in a hurry at the school gates at Weare Academy First School, or on a friend's drive in Rackley. Meaning? Spills outside the inlet never touch the engine at all. AdBlue inside the diesel tank does. If there is AdBlue in the tank, starting the car will suck it in, and it wouldn't tell you which either. What to do: treat it as if it was put in. Don't start it. Phone and give what you saw: we'd sooner find a clean tank than empty one once the motor has been run. ## Tarnock: what every AdBlue drain has in common Whichever situation you are in, the job starts the same way. Wherever your vehicle is — Wellington Arms's car park, a road by St Congar, a drive, a forecourt — the van arrives and we ask for the liquid, the amount, and whether the motor has turned over. Those replies settle the work, and you get the quote by phone, before anyone sets off. Then that tank is emptied and the fuel system flushed thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not rinse out on its own. Next comes the fuel filter — cleaned, or swapped when necessary — then fresh diesel, and a test of your car. If your engine hasn't run, most jobs take about half an hour once we're there. Our technicians start the car at the end. Our engineers make sure it runs correctly on fresh diesel before we go. Lasting damage is very rare if it's noticed soon, and the entire job is done where the vehicle is. For your insurer: the engineer's report and the VAT invoice. For you: payment that day, nothing upfront. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way. ## About Tarnock and where it is Tarnock is a small hamlet in Somerset, situated inland near the villages of Biddisham and Badgworth.
