--- title: What Now? AdBlue in a Diesel Tank The Crook canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/the-crook-kent/ location: The Crook county: Kent latitude: 51.155080 longitude: 0.406390 service: AdBlue in a Diesel Tank updated: 2026-10-17 --- # AdBlue in the Diesel Tank in The Crook, and What to Do Next All of it turns on a single fact: if your engine has started since the AdBlue went in — more than anything else. Wherever your vehicle is — Castle Hill, The Crook — don't start a motor that has not been started yet. Phone 0333 366 0103 with your key and engine both off. In The Crook, that is generally emptied and flushed where it stands. Already started? Pull over once you safely can, then switch everything off. It's a larger job, yet step one doesn't change. Anywhere around Kent it took place, one of the situations below matches yours. ## The Crook forecourt: AdBlue in a diesel at the pump Imagine it: stood by the petrol pump, holding the bottle, you realise the cap you opened wasn't the correct one. Maybe you are at the Esso, maybe at the BP, perhaps somewhere else around The Crook. The point: of all places to find out, this is the best. Still in the tank, with nothing pulled through: that's where the AdBlue sits. Your move: stay out of the car, even if the queue wants clearing. Get the staff to help rolling it into a bay, save the receipt, then phone us from there. The equipment is explosion-proof and safe on a live forecourt, so a car that cannot be pushed clear is cleared right at the pump. ## AdBlue in your diesel tank on a The Crook drive? The warning light had been on for days. Only at the recycling bin, the empty bottle in hand, did you glance back at the cap you'd used on the driveway. It occurs on driveways just off Knowle Road as commonly as anywhere. Put simply: if the vehicle hasn't been driven since, it is nearly equal to spotting it at the forecourt. Being unable to blend, AdBlue settles low in the tank and waits. A night standing changes none of that. What to do: leave the keys inside the house so nobody moves the vehicle in the morning. Then ring. We drain the vehicle on your driveway, whether that is around The Crook or out in Hill Top. Even at night, the pumps are quiet enough for a driveway. ## Drove off with AdBlue in a diesel in The Crook? Lumpy running, smoke, falling power or a lit dashboard started a short way beyond the top-up. Anywhere along Crook Road or else on the road towards Southend-on-Sea — under 50 miles away. What it means: the fuel system has pulled the AdBlue in. Through your filter, along the pipework, and — the further the distance — on into the high-pressure pump and each injector. Each mile and each restart takes it further. Stop somewhere safe — that is the first step — then switch it off. On the M20, under 15 miles from The Crook, that means the next junction, not the services further on. Don't restart the vehicle to see if it has cleared; it will not have. Tell us know the mileage driven when you ring. ## AdBlue in the wrong tank of a hire, lease or company car Seven days ago, the car was new to you. On your own car, AdBlue is absent or somewhere else. On this one, its cap is right next to your diesel cap — a surprise to you. Throughout Kent, no one is safe from it. What it means: the same as the situations above, depending on whether it has run, with one more stage. Many hire and company contracts need the owner's approval before repairs. Sorting it before the van arrives is quicker, so phone the rental company or your fleet manager, then us. Leave it off while the reply arrives, whether you're parked outside Paddock Wood or near All Saints. ## The Crook: unsure if it was AdBlue in your diesel tank? Occasionally the fair answer is "I think so". The bottle is lighter than it should be, there's a faint smell of ammonia round your filler, and you cannot remember which cap you took off. It might have been on a friend's drive in Isle of Wight, or rushing outside Brenchley and Matfield Church of England Primary School at the school run. What it means: a little spilled about the filler does no damage to your motor. The diesel tank with AdBlue inside is another matter. You cannot tell which by turning the key, and doing so will pull in any AdBlue that is in that tank. What to do: treat it as if it went in. Do not start the vehicle. Describe what you noticed on the phone. A clean tank looked at counts as a better result than an already-run one emptied. ## What each AdBlue drain in The Crook has in common Whatever the situation, a single opening applies. Three things are asked once we arrive — at a forecourt, a drive, a road by Castle or the car park at The Castle Inn: the liquid, the quantity, and if the motor has run. Those answers determine the work, and you hear our price by phone, before anyone sets off. Draining your tank comes next, followed by a careful flush — more important after urea than after petrol, since crystals and corrosion won't clear by themselves, no matter how long you wait. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Where the engine hasn't run, allow roughly half an hour on site, in most cases. Finally, our engineers fire it up. Our engineers confirm it runs smoothly on new diesel before we leave. Permanent damage is very unusual when it's spotted soon, and the whole job is done where the vehicle is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Dig out your insurance before we're en route: cover for misfuelling comes built into many policies. ## About The Crook The Crook is a small suburban area situated on the riverside in Kent, with a relatively low elevation of 99 metres.
