--- title: Braughing: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/braughing-hertfordshire/ location: Braughing county: Hertfordshire latitude: 51.906490 longitude: 0.026650 service: AdBlue in a Diesel Tank updated: 2026-10-26 --- # Braughing: AdBlue in the Diesel Tank? Find Your Situation One thing counts above all when AdBlue is in a diesel tank, and that is if the engine has been started since. If it hasn't, keep it that way, whether your car is around Braughing itself or out in Puckeridge. Usually that is draining and thoroughly rinsing it on the spot around Braughing — so keep the ignition and motor off and call 0333 366 0103. If it's run, stop as soon as it is safe then switch off. The job is bigger, but the first step is the same. Find the situation below that matches yours, wherever in Hertfordshire it happened. ## At the petrol pump in Braughing: AdBlue in a diesel Picture it: stood by the pump, holding the bottle, you spot the cap you opened wasn't the right one. Somewhere in Braughing, then — Amco, BP, or somewhere else nearby. Meaning? Finding out on the forecourt is as good as it can be. No pump has pulled it in, so the AdBlue stays only inside that tank. What to do: do not get back in and crank it to clear the pump. Three things: a shove into a bay with the staff helping, the receipt kept, and a ring to us from where you stand. If it can't be moved, it can be drained at the petrol pump: the equipment is explosion-proof and fine on a busy forecourt. ## At home around Braughing with AdBlue in your diesel tank For days the dashboard had been warning you. A bottle from the garage, tipped in at the drive — and it was just by the recycling that the cap got your eye. Houses just off Green Hill Close are hit as often as anywhere else. Meaning? Provided the vehicle has not moved since, it is second to the pump case. AdBlue does not mix with diesel; it sinks to the bottom of your tank and waits there. Overnight doesn't change that. Keep the keys indoors tonight — or a person might drive it away at breakfast — and phone us. Church End or Braughing: whichever your drive is, that is where it gets emptied. The pumps are quiet enough to use outside a house at night. ## On the road in Braughing with AdBlue in a diesel Lumpy running, smoke, falling power or a lit dashboard arrived a mile or two after the top-up. Anywhere along Green Hill or heading towards St Albans — under 25 miles away. Put simply: the AdBlue has been pulled into the system. Distance sets how far it goes: filter and lines first, then the high-pressure pump and every injector. More miles, more restarts: further it travels. What to do: pull over where it is safe to do so then switch off. On the M11, under 10 miles from Braughing, that means the next exit, not the services further on. Starting it again to test achieves nothing — AdBlue never clears itself. Phone us and say how far you went. ## AdBlue in the wrong tank of a hire, lease or company car It is a motor you have had for a week. The AdBlue filler sits right alongside the diesel one, which you didn't know, since your own car either has no AdBlue or keeps it somewhere else. Throughout Hertfordshire, nobody is immune. Meaning? Whichever applies above applies too — run or unrun — and one extra stage. Many hire and company contracts want the owner to approve work on the vehicle. What to do: call the hire firm or your fleet manager first, then us. That's faster settled before our technicians get there than after. Leave the car off while the answer arrives, even if you're waiting outside Bishops Stortford or near St. Mary the Virgin. ## Not sure it was AdBlue in the diesel tank, Braughing? Truthfully, the only answer may be that you think so. Which cap came off, you can't say; meanwhile the bottle feels lighter than it ought to, and ammonia lingers by your filler. Possibly it happened in a hurry at the school gates at Jenyns First School and Nursery, or on a friend's drive in Braughing Friars. Meaning? Drips around the inlet never touch your motor at all. AdBlue inside your diesel tank does. If there is AdBlue in the tank, starting the car would draw it in, and it wouldn't tell you which either. Your move: behave as if it got in, and never start your engine. Tell us what you saw on your phone. A clear tank looked at counts as a better outcome than an already-run one emptied. ## Every AdBlue drain in Braughing shares these steps Each situation gets the same opening to the work. Filling station, drive, Golden Fleece's car park or a street by Braughing Community Centre — the van comes to the vehicle, and three questions come next: what fluid, what amount, and whether it has run. Those answers determine this work, and you get the quote on the phone, before anybody heads out. Then your tank is cleared and the system purged thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't rinse out on its own. Finally come the filter, flushed or renewed if necessary; clean diesel; and a check of your vehicle. If your motor hasn't run, most jobs take about half an hour once we are there. The final step is starting it. Our check that it runs smoothly on fresh diesel comes before our engineers go. We do the whole job where the vehicle is, and long-term damage is very rare when it has been noticed early. For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, no money upfront. Check your insurance while we arrive: cover for misfuelling is included in many policies. ## About Braughing itself Braughing is a village in Hertfordshire, situated on the riverside in the Eastern region of England.
