--- title: Fen Drayton: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/fen-drayton-cambridgeshire/ location: Fen Drayton county: Cambridgeshire latitude: 52.297680 longitude: -0.041480 service: AdBlue in a Diesel Tank updated: 2026-10-07 --- # AdBlue in the Diesel Tank in Fen Drayton, and What to Do Next What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the motor has been run since it was put in. Anywhere the car stands — Swavesey, Fen Drayton — don't start an engine that hasn't been started yet. Keep nothing on, phone 0333 366 0103, and count on a proper flush after a drain, carried out right where the car stands around Fen Drayton. Already run? Pull over when you safely can, then turn everything off. A bigger job, then, but the identical first step. Anywhere across Cambridgeshire it took place, one of the situations below matches yours. ## At the pump around Fen Drayton: AdBlue in a diesel The cap you unscrewed was the wrong one — and you just notice it while you are standing at the pump, bottle or nozzle in your hand. It could be the Shell, or perhaps the another forecourt nearby, or a different forecourt in Fen Drayton. In short: there is no better place to be to spot it. Nothing has pulled it in, and so the AdBlue sits just inside that tank. Your move: stay out of the driver's seat, even if the pump wants freeing. Phone us from the forecourt once the car is in a bay — the staff will lend a hand to push it — then save the receipt. Stuck beside the pump? Our explosion-proof kit makes a live forecourt safe, so it can be drained where it is. ## AdBlue in your diesel tank on a Fen Drayton 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. Right off Vermuyden Way is not different from any other place. Put simply: if the car hasn't been driven since, it is nearly equal to finding out at the forecourt. As it is unable to blend, AdBlue settles to the base in the tank and waits. A night parked changes nothing. Next: keys in the house, so no one takes the vehicle off first thing. After that, phone. Fenstanton or Fen Drayton: wherever your driveway is, that's where it gets cleared. Even at night, our pumps stay quiet enough for a residential street. ## On the road around Fen Drayton with AdBlue in a diesel Topped up, pulled away, and soon the engine was turning unevenly, smoking, down on power, or flashing up the dash. Maybe it was on Park Lane, maybe on the way out towards Cambridge, under 10 miles away. The point: your system has pulled AdBlue through already. It has been through the fuel filter and the fuel lines and, the further you went, into your high-pressure pump and your injectors. Every restart, like each mile, carries it deeper. Pull in somewhere safe — that's the first step — then turn everything off. Exit at the next junction — not the services further along — if you're on the M11, under 10 miles from Fen Drayton. Starting it again to check gets nothing — AdBlue doesn't clear itself. About how far had it go? Tell us when you call. ## AdBlue in the wrong tank: hire, lease and company vehicles A week back, it was new to you. The AdBlue filler sits right alongside the diesel filler, which you didn't know, since your own motor either has no AdBlue or keeps it somewhere else. Throughout Cambridgeshire, nobody is immune. What it means: the same as the scenarios above, depending on whether it has run, with one more stage. Any work on the car often requires the owner's go-ahead under rental or fleet terms. Next: ring the hire company or the fleet manager first, then us — sorting it before we arrive is faster. Waiting for a reply in the car park outside Huntingdon, or near Fen Drayton Village Hall? Leave the car off meanwhile. ## Unsure about AdBlue in your diesel tank in Fen Drayton? "I think so" is sometimes the most honest as it gets. The bottle is lighter than it should be, there is a faint smell of ammonia about your filler, and you cannot remember which cap you took off. Maybe it happened in a hurry at the school gates at Fen Drayton Primary School, or on a friend's drive in Boxworth End. Meaning? Spills outside the inlet don't touch the motor at all. AdBlue inside your diesel tank does. You cannot tell which by turning the ignition, and doing so will pull in any AdBlue that is in that tank. Your move: behave as if it did, and don't start your motor. Inspecting a tank that turns out clean beats emptying one after it has been run — so ring and describe to us what you saw. ## Every AdBlue drain in Fen Drayton shares these steps Whichever situation you are in, the job starts the same way. Three things come when our engineers reach the car — at a forecourt, a drive, a street by St Mary's or the car park outside The Three Tuns: the liquid, the quantity, and if the motor has run. Answers shape the job; the quote comes by phone while no one has left yet. AdBlue crystallises and is corrosive to some metals used in fuel systems, so it does not rinse out unaided; that's why a full flush, after this drain, counts far more with AdBlue than with petrol. Next is your filter — cleaned, or swapped where needed — followed by clean diesel, and a test of the car. The majority of unrun vehicles are a half-hour visit from the moment our technicians arrive. Finally, we fire it up. With new diesel in, it runs while our technicians confirm it's running properly, and then we head off. When it's caught early, the car very seldom has lasting damage, and the whole job happens where it is. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, nothing in advance. Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we're on the way. ## About Fen Drayton Fen Drayton is a village in Cambridgeshire, situated on the shores of lakes and wetlands at a low elevation of around 12 metres.
