--- title: What Now? AdBlue in a Diesel Tank Hartley Hill canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/hartley-hill-kent/ location: Hartley Hill county: Kent latitude: 51.372040 longitude: 0.315490 service: AdBlue in a Diesel Tank updated: 2026-10-08 --- # AdBlue in the Diesel Tank in Hartley Hill: What Now? Has your engine run since the AdBlue went in? This one point settles almost everything about what comes next. Wherever the car stands — Longfield Hill, Hartley Hill — never start an engine that hasn't been started yet. Normally that means emptying and properly rinsing it on the spot around Hartley Hill — and so keep your key and motor off then call 0333 366 0103. Pull over the moment it is safe then turn off, if it has been run. Stage one remains unchanged, even though the job grows. Further down: the cases we meet, anywhere in Kent. Choose yours. ## Hartley Hill forecourt: AdBlue in a diesel at the pump Only now, bottle yet in your hand, you realise that the cap you opened was the wrong one, right at the pump. Anywhere around Hartley Hill, then — Gulf, Shell, or anywhere else nearby. Put simply: no better spot to be to spot it. The AdBlue is in your tank and nowhere else. Nothing has sucked it in. Do this: keep out of the car, even if the pump wants clearing. A few things: a shove into a space with the attendants helping, the receipt kept, and a call to us from the forecourt. Can't move it beside the petrol pump? Our explosion-proof equipment keeps a busy forecourt sensible, so it can be drained where it is. ## Hartley Hill, at home: AdBlue in your diesel tank The warning light had been on for days. Picked up a bottle, tipped it in outside the house, recycled the empty — and at that point looked at the cap a second time, after the fact. Right off Hartley Hill is not different from anywhere. Meaning? As long as your vehicle hasn't moved since, it is close to the pump case. Diesel and AdBlue keep separate: the AdBlue drops to the floor of that tank and remains put, however long the night. Next: stop any early move by putting the keys in the house, then phone us. We drain the car on your drive, whether that is around Hartley Hill or out in New Ash Green. Late-night drains beside a house are no problem: the pumps are low-noise. ## AdBlue in a diesel and already driving around Hartley Hill? You filled up, set off, and a mile or two later your engine began to run roughly, smoke, lose power or light up the dashboard. Somewhere on Church Road or else on the road towards London — under 25 miles away. Meaning? The pump has taken the AdBlue up. Past the fuel filter, along the lines, and — the more the distance — deeper into the injection pump and each injector. Each restart, like every mile, pushes it deeper. Next: pick a sensible spot, pull in, then switch the engine off. Hartley Hill sits under 3 miles from the M20; there, pull off at the first junction rather than pushing on for the services. Restarting it to test gets nothing — AdBlue doesn't clear on its own. Tell us hear the distance driven as you call. ## AdBlue in the wrong tank of a hire, lease or company car A week ago, the car was unknown to you. Unknown to you, the AdBlue and diesel inlets sit next to each other here — not like your own vehicle, which has none or stores it elsewhere. Across Kent, no one is safe from it. The upshot: just as above, split by whether it ran, only with one added stage. The owner often needs to approve any work, under many hire and company agreements. Sorting it before we turn up is faster, so ring the hire company or your fleet manager, then us. Stranded near All Saints or at Longfield until someone replies, your vehicle remains turned off throughout. ## Hartley Hill: unsure if it was AdBlue in the diesel tank? At times, "I think so" is the most you can honestly say. The bottle is lighter than it should be, there's a faint smell of ammonia round the filler, and you cannot remember which cap you took off. Perhaps it happened in a hurry at the school gates at New Ash Green Primary School, or on a friend's drive in Ash. In short: a spill round the filler leaves the motor no harm. A diesel tank with AdBlue inside is another story. Firing up the vehicle cannot tell you which, and if there is AdBlue in your tank it will pull it in. Take it that it went in, and don't start the key. Call us and describe 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 Hartley Hill has in common Whatever the situation, one opening applies. We come to the vehicle, whether it's on a forecourt, a drive, the car park at The Black Lion or a side street near New Ash Green & Hartley Cricket Club, and ask three things: what went in, roughly how much, and whether the motor has been run. Those replies determine this work, and you hear the quote by phone, before anybody heads out. AdBlue crystallises and is corrosive to certain metals in fuel systems, so it won't wash out on its own; that's why the flush, after the drain, matters much more with AdBlue than with petrol. Finally are the fuel filter, cleaned or replaced if necessary; fresh diesel; and a check of the vehicle. Most unstarted vehicles are a half-hour visit from the moment we arrive. Last, our technicians start it. Our check that it runs correctly on new diesel comes before our engineers head off. The whole job is done where the car is, and if it is spotted early, long-term damage is very uncommon. For your insurer: an engineer's report and the VAT invoice. For you: payment that day, nothing in advance. Worth remembering: lots of insurers offer misfuelling cover, and so a check of your policy as you wait is worthwhile. ## About Hartley Hill Hartley Hill is a suburban area in Kent, situated inland at an elevation of 128 metres, and is located approximately 21 miles from London.
