--- title: AdBlue in a Diesel Tank Hersden? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/hersden-kent/ location: Hersden county: Kent latitude: 51.315900 longitude: 1.162060 service: AdBlue in a Diesel Tank updated: 2026-10-04 --- # AdBlue in the Diesel Tank in Hersden, and What to Do Next Everything turns on one detail: whether your engine has started after the AdBlue went in — more than anything else. If it hasn't, keep it that way, whether your car is around Hersden itself or out in Stodmarsh. Normally that means emptying and properly purging it right there in Hersden — and so leave the ignition and engine off then phone 0333 366 0103. Pull over the moment you safely can and switch off, if it has already run. It is a bigger job, yet step one doesn't change. Below: the cases our technicians see, wherever across Kent. Pick yours. ## Hersden forecourt: AdBlue in a diesel at the pump The cap you opened was the wrong one — and you just notice it as you're stood at the pump, bottle or the nozzle in hand. Maybe you are at the Esso, perhaps at the Sainsbury's, possibly somewhere else in Hersden. Meaning? Spotting it on the forecourt is the best it gets. Just your tank has AdBlue; no component past it has drawn it in. Next: avoid the temptation to fire it up just to move away from the petrol pump. Have the staff to help rolling it to a bay, hold on to the receipt, then ring us right there. If it cannot be shifted, it can be cleared at the petrol pump: the equipment is explosion-proof and fine on a working forecourt. ## At home in Hersden with AdBlue in your diesel tank Several days had passed with the dash light on. Only by the recycling, the empty bottle in hand, did you glance back at the cap you'd opened at the driveway. Houses just off The Elms get caught out as often as anywhere else. What it means: if you haven't driven since, this is nearly as good as the forecourt. On the bottom of that tank is exactly where AdBlue stays, because it won't mix with diesel — and a night passing changes nothing of the difference. Next: the keys indoors, so nobody takes your vehicle anywhere first thing. After that, phone. Westbere or Hersden: wherever your driveway is, that is where it gets drained. Even at night, our pumps stay quiet enough for a residential street. ## On the road around Hersden with AdBlue in a diesel Lumpy running, smoke, falling power or a glowing dashboard arrived a mile or two after the fill. Maybe driving for Canterbury, under 5 miles away, or simply along Sutton Road. In short: the AdBlue has been pulled into the fuel system. Past your filter, through the pipework, and — the more the mileage — deeper into the high-pressure pump and every injector. It goes further with each extra mile driven and every restart. What to do: pull over where it's safe to do so and switch off. Exit by the next junction — not the services beyond — if you are on the M2, under 15 miles from Hersden. No test restarts: clearing itself is not something AdBlue will do. Phone us and say how far you travelled. ## AdBlue in the wrong tank of a hire, lease or company car A week back, the car was unknown to you. The AdBlue filler sits right beside the diesel one, which you did not know, since your own motor either has no AdBlue or keeps it somewhere else. Throughout Kent, nobody 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 agreements want the owner to approve work on the car. What to do: ring the hire firm or your fleet manager first, then us. That is faster settled before we get there than after. Stuck by Hersden Community Centre or outside Sturry till the firm replies, the vehicle remains turned off throughout. ## Unsure about AdBlue in the diesel tank in Hersden? "I think so" is sometimes the most honest answer there is. Which cap was taken off, you can't recall; meanwhile the bottle weighs less than it ought to, and a whiff of ammonia hangs by your filler. Possibly it happened in a hurry at the school gates at Water Meadows Primary School, or on a friend's drive in Chislet Forstal. Meaning? Drips outside the filler don't touch the engine at all. A diesel tank with AdBlue in it is a different matter. If there is AdBlue in that tank, firing up your car will draw it in, and it wouldn't tell you which either. Next: act as though it got in, and leave your engine off. Call us and describe what you saw; we would rather check a tank that turns out clean than drain one that has already been run. ## The common ground in each Hersden AdBlue drain Whichever scenario you are in, this job starts the same way. Forecourt, drive, Ye Olde Yew Tree Inn's car park or a road by Westbere Village Hall — our van comes to the car, and three questions follow: what fluid, what amount, and whether it ran. Your price comes over the phone, ahead of anyone setting off, and those answers set the job. A thorough flush follows the drain. With petrol it is routine; with AdBlue it is essential, since deposits form and certain metals are attacked, and none of that washes out unaided. Fresh diesel is put in after the filter has been cleaned or replaced, and the car is finally checked. If the engine has not run, most jobs take about half an hour once we're there. Our technicians fire it up last. Before our technicians go, it's tested to confirm it runs smoothly on clean diesel. Our technicians do the entire job where the vehicle is, and permanent damage is very uncommon if it has been noticed soon. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, nothing upfront. It is worth remembering: lots of insurers offer misfuelling cover, so a quick look at your documents while we travel is worthwhile. ## About Hersden itself Hersden is a village in Kent, situated on the banks of the River Stour at an elevation of around 33 metres.
