--- title: Highfields: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/highfields-gloucestershire/ location: Highfields county: Gloucestershire latitude: 51.679350 longitude: -2.345880 service: AdBlue in a Diesel Tank updated: 2026-10-18 --- # AdBlue in the Diesel Tank in Highfields: What Now? What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the motor has run since it was put in. Not started so far? Then leave it that way, wherever your car sits — Highfields or Dursley. Normally that is emptying and thoroughly cleaning it right there in Highfields — and so keep your key and engine off then call 0333 366 0103. Stop the moment it is safe and turn off, if it has already run. Stage one remains unchanged, even if the job grows. Wherever in Gloucestershire it happened, one of the cases below matches yours. ## On a Highfields forecourt with AdBlue in a diesel Only now, bottle yet in hand, you realise that the cap you opened was the wrong one, right at the petrol pump. Be it Texaco, Shell or somewhere else around Highfields, the case is identical. Meaning? Spotting it here is as good as it gets. Nothing has drawn it in, and so the AdBlue sits just in that tank. What to do: do not get back in and fire it up to clear the pump. A few jobs: a push into a bay with the attendants helping, the bottle kept, and a ring to us from where you stand. The equipment is explosion-proof and safe on a live forecourt, so a vehicle that cannot be pushed away gets cleared where it is at the pump. ## AdBlue in the diesel tank at home in Highfields For days the dash had been nagging you. A bottle from the garage, tipped in at the driveway — and it was just at the recycling that the cap got a second look. It occurs on drives just off Highfields Approach as commonly as anywhere. Put simply: if your car has not been driven since, it is nearly as good as finding out at the forecourt. Diesel and AdBlue stay separate: the AdBlue drops to the base of that tank and remains put, however long the night. Next: the keys indoors, so nobody takes your vehicle off first thing. Then, phone. Your drive is where it gets drained, be it in Highfields or Woodmancote. Late-night drains beside a house are fine: the pumps are quiet. ## Set off with AdBlue in a diesel around Highfields? Topped up, pulled away, and soon your engine was running unevenly, smoking, losing power, or flashing up your dash. Yellow Hundred Close, perhaps, or the way to Gloucester — a run of under 15 miles. What it means: your fuel system has pulled the AdBlue in. The high-pressure pump and every injector see it as well on a bigger trip, after the filter and pipework have it. It travels deeper with each extra mile driven and each restart. Pull in safely — that is the next job — then turn it off. Service stations further on are too far: from the M5, under 3 miles out of Highfields, use the next junction. Don't restart it to see if it has cleared; it will not have. Roughly how far had it go? Tell us when you call. ## AdBlue in the wrong tank: hire, lease and company motors It's a vehicle you have had for a week. The AdBlue filler sits right beside the diesel one, which you didn't know, because your own car either has no AdBlue or keeps it somewhere else. Across Gloucestershire, no one is safe from it. In short: an extra step on top of the cases above, which depend on if it's run. Any work on your car often requires the owner's go-ahead under hire or fleet terms. What to do: ring the hire firm or your fleet manager first, then us. That is faster settled before our technicians arrive than after. Waiting for an answer in the car park at Cam & Dursley, or beside St Mark? Keep the engine off meanwhile. ## Not sure it was AdBlue in your diesel tank, Highfields? At times, "I think so" is all anyone can honestly say. A slight ammonia-like whiff lingers around the filler, the bottle feels too light, and which cap came off is hard to recall. A hurried top-up by the gates of Dursley Church of England Primary Academy, or a visit to a friend in Farfield: either fits. Meaning? Drips around the filler never touch the motor at all. Once it is inside the diesel tank, though, it does. If there is AdBlue in your tank, starting the vehicle will draw it in, and it wouldn't tell you which either. Take it that it got in, and never turn your key. Call us and explain what you saw; we'd rather check a tank that turns out free of AdBlue than drain one that has already been run. ## What every AdBlue drain around Highfields has in common Whichever situation you are in, the job starts the same way. Wherever the car stands — Old Bell Hotel's car park, a road beside Bethany Chapel, a drive, a forecourt — the van gets there and we ask about the liquid, the quantity, plus if the engine has turned over. Answers shape the work; the price comes by phone whilst nobody has set off yet. A thorough flush follows this drain. With petrol it's standard; with AdBlue it's crucial, because deposits build up and some metals are attacked, and none of it rinses out unaided. Finally come the fuel filter, cleaned or replaced as needed; clean diesel; and a test of your vehicle. Where the motor has not been started, expect about half an hour once we arrive, for most cases. The last step is starting the car. With fresh diesel in, it runs while our engineers make sure it's running correctly, and then we go. Lasting damage is very unusual when it is spotted soon, and the entire job is done where the car is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies cover misfuelling, so check yours while the van travels. ## About Highfields Highfields is a suburban area in Gloucestershire, situated near the River Severn at an elevation of around 69 metres.
