--- title: AdBlue in a Diesel Tank Chieveley: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/chieveley-berkshire/ location: Chieveley county: Berkshire latitude: 51.463790 longitude: -1.316470 service: AdBlue in a Diesel Tank updated: 2026-10-09 --- # AdBlue in the Diesel Tank in Chieveley, and What to Do Next One fact counts most once AdBlue is in a diesel tank, and it is if your motor has run afterwards. If it has not, keep it that way, whether the vehicle is in Chieveley itself or out in Worlds End. Leave the engine and the ignition off then call 0333 366 0103; it's generally a drain and a thorough flush, done where the car is around Chieveley. Where your engine has been run, stop somewhere safe straight away, then switch the vehicle off. The job is bigger, yet the first stage is the same. Compare your case to a situation from the ones below, wherever across Berkshire you happen to be. ## AdBlue in a diesel on a Chieveley forecourt Only at this point, bottle yet in hand, it dawns on you that the cap you opened was the wrong one, there at the petrol pump. Somewhere in Chieveley, then — BP, Long Lane Garage, or anywhere else nearby. What it means: this is the best place to find out. Nothing has pulled it through, and so the AdBlue stays only in your tank. Your move: stay out of the car, however much the pump wants freeing. Three things: a push into a bay with the staff assisting, the bottle kept, and a call to us from the forecourt. Stuck by the pump? Our explosion-proof equipment makes a live forecourt safe, so it can be drained in place. ## At home in Chieveley with AdBlue in the diesel tank On your dash, a reminder had been lit all week. Only at the recycling bin, the empty bottle in hand, did you glance back at the cap you'd used at the drive. Just off Church Lane is not different from any other place. Meaning? As long as the car hasn't been driven since, it's close to the forecourt case. Diesel and AdBlue stay separate: the AdBlue settles to the floor of the tank and remains there, no matter how long the night. Next: keys in the house, and so nobody takes your car anywhere first thing. Then, phone. Your drive is where it gets emptied, be it in Chieveley or Horsemoor. The pumps are quiet enough to use outside a house after dark. ## AdBlue in a diesel and already driving around Chieveley? Rough running, smoke, falling power or a glowing dashboard started a short way after the top-up. Maybe it was on High Street, perhaps on the way out towards Oxford, under 25 miles away. What it means: the system has drawn the AdBlue in. It has been through the filter and the fuel lines and, the further you went, into the high-pressure pump and the injectors. It goes further with every mile covered and each restart. Your move: pull up anywhere sensible, then switch your engine off. On the M4, under a mile from Chieveley, that means the next exit, not the services further on. It won't have cleared, so there is no point restarting to find out. Roughly what distance did it go? Say so as you phone. ## A hire or company car with AdBlue in the wrong tank? You've only driven this vehicle a week. Unbeknown to you, the AdBlue and diesel inlets are next to each other here — not like your own car, which has none or stores it in another spot. It can happen to anyone, anywhere around Berkshire. What it means: the same as the situations above, depending on whether it's run, with one more stage. Many rental and fleet contracts need the owner's approval for repairs. What to do: call the hire firm or your fleet manager first, then us. That is quicker settled before we get there than after. Stuck near St Mary the Virgin or at Newbury Racecourse till someone answers, your vehicle remains turned off the whole time. ## Unsure about AdBlue in your diesel tank around Chieveley? Honestly, the only answer may be that you think it did. What cap was taken off, you can't recall; meanwhile the bottle weighs lighter than expected, and a whiff of ammonia lingers by your filler. The gates of Chieveley Primary School in a hurry, perhaps, or a friend's driveway over in Curridge. The point: your motor is not hurt by a little AdBlue spilled around the filler. In your diesel tank, by contrast, AdBlue damages it. If there is AdBlue in the tank, firing up your car will draw it in, and it wouldn't tell you which either. Do this: act as if it got in, and don't start your engine. Tell us what you noticed on the phone. A clean tank looked at counts as a happier result than an already-run one drained. ## Each AdBlue drain in Chieveley shares these stages Each case has the same opening to the work. Wherever the car is — Red Lion's car park, a road beside Newbury Show Ground, a driveway, a filling station — our van gets there and we ask for the liquid, the amount, and if the engine has been run. The price is given on the call, before a van leaves, and the replies set the job. Draining your tank comes first, followed by a careful flush — more vital with urea than after petrol, since crystals and corrosion won't clear by themselves, no matter how long you wait. Clean diesel goes in after the filter has been cleaned or replaced, and your car is then tested. Where the engine hasn't been started, expect roughly half an hour on site, in most cases. The last step is firing it up. With fresh diesel in, it runs while our technicians make sure it's running smoothly, and then we head off. When it's noticed soon, the car very rarely has permanent damage, and the entire job takes place where it is. Payment comes that day, never in advance. For your insurer, there is a VAT invoice plus a written report from the engineer. Worth knowing: lots of insurers include misfuelling cover, so a quick look at your documents as we travel is worthwhile. ## About Chieveley and where it is Chieveley is a rural village in Berkshire, situated inland at an elevation of 126 metres, approximately 51 miles west of London.
