--- title: What Now? AdBlue in a Diesel Tank Fishery canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/fishery-berkshire/ location: Fishery county: Berkshire latitude: 51.513800 longitude: -0.706700 service: AdBlue in a Diesel Tank updated: 2026-10-06 --- # AdBlue in the Diesel Tank in Fishery: What Now? Has your motor turned over since the AdBlue went in? That single question decides almost everything else from here. Not run yet? Then leave the vehicle like that, whether the car is — Fishery or Boyn Hill. Call 0333 366 0103 with your ignition and engine both off. In Fishery, such a case is generally drained and flushed where it stands. If it's run, stop as soon as it is safe then switch off. The job is bigger, yet the first stage is the same. Anywhere around Berkshire it took place, one of the situations below fits yours. ## At the pump around Fishery: AdBlue in a diesel You're 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. Somewhere around Fishery, then — Esso, Texaco, or anywhere else close by. What it means: this is the ideal location to find out. Just your tank has AdBlue; no part beyond it has taken it in. Freeing the pump is no excuse to start it — so don't get back in. Phone us from the forecourt once your vehicle is in a bay — the attendants will help push it — then keep the receipt. The equipment is explosion-proof and safe on a live forecourt, so a car that can't be pushed away gets cleared right at the petrol pump. ## AdBlue in the diesel tank at home around Fishery Several days had passed with the warning light on. A bottle bought at the garage, tipped in at the drive — and it was just at the bin that the cap got your eye. It happens on drives just off Glebe Road as regularly as anywhere. Meaning? As long as your car hasn't been driven since, it is second to the forecourt case. Diesel and AdBlue stay apart: the AdBlue drops to the floor of your tank and remains there, no matter how long it waits. What to do: leave your keys inside the house so nobody moves the vehicle in the morning. Then ring. Your drive is where it is drained, be it in Fishery or Bray. Our pumping kit runs quietly enough that it won't wake the neighbours at night. ## On the road in Fishery with AdBlue in a diesel A short way after topping up, the engine began misbehaving: roughness, smoke, lost power, lights on your dash. It might have been driving to St Albans, under 25 miles away, or simply along Church Road. The upshot: your system has drawn AdBlue in already. It has been through the fuel filter and your lines and, the further you went, into the high-pressure pump and the fuel injectors. It goes further with every mile driven and each restart. Next: pick a safe place, pull in, then switch the motor off. Fishery sits under a mile from the A308(M); there, pull off at the next junction rather than pressing on for the services. Starting it again to check gets nothing — AdBlue never clears itself. Call, and say what distance the car went. ## Hire, lease or company car with AdBlue in the wrong tank It is a car you have had for a week. Your own car either has no AdBlue or keeps it elsewhere, and so no one told you the AdBlue cap was just beside the diesel. Across Berkshire, nobody is immune. What it means: the same as the scenarios above, depending on whether it's run, with one more step. Many rental and fleet agreements require the owner's approval for work. Do this: rental firm or fleet manager first, us second, since sorting it beforehand saves time. If you are stuck in the car park at Maidenhead, or by Desborough Bowling Club, whilst you wait for an answer, leave the vehicle off. ## Not sure it was AdBlue in the diesel tank, Fishery? Honestly, the only answer might be that you think so. Lighter, the bottle; a hint of ammonia near your filler; no clear memory of which cap. Sound familiar? Possibly it happened in a hurry at the school gates at Oldfield Primary School, or on a friend's drive in Dorney Reach. What it means: a little spilled round the filler does no harm to the engine. In your diesel tank, however, AdBlue damages it. Firing up the vehicle will not tell you which, and if there is AdBlue in the tank it would draw it in. Assume it got in, and never start your key. Phone and give the details: we'd sooner confirm a tank free of AdBlue than empty one once the engine has been run. ## What each AdBlue drain around Fishery has in common The job begins the same way, whatever the situation. Forecourt, driveway, The Hinds Head's car park or a road beside Saint Michael's — our van reaches the vehicle, and three questions come next: which fluid, what quantity, and whether it has run. Replies set the work; the quote follows on the call while no one has set off yet. AdBlue crystallises and is corrosive to certain metals in fuel systems, so it won't rinse out unaided; that is why the flush, after the drain, matters much more with AdBlue than with petrol. Then is the fuel filter — flushed, or replaced where necessary — followed by fresh diesel, and a test of the vehicle. The majority of unstarted vehicles are a half-hour visit from the moment our engineers turn up. We start the car at the end. Before our technicians head off, it's checked to make sure it runs properly on fresh diesel. Our technicians do the entire job where your car is, and permanent damage is very unusual if it has been caught quickly. Nothing is paid upfront, settlement happens on the day, and you get what the insurer asks for: an engineer report and a VAT invoice. Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way. ## About Fishery Fishery is a suburban area in Berkshire, situated on the riverside with a relatively low elevation of 25 metres.
