--- title: Pottersheath: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/pottersheath-hertfordshire/ location: Pottersheath county: Hertfordshire latitude: 51.849620 longitude: -0.203100 service: AdBlue in a Diesel Tank updated: 2026-10-12 --- # AdBlue in the Diesel Tank in Pottersheath: What Now? Everything hinges on one fact: if your engine has started after the AdBlue was added — more than anything else. Anywhere your vehicle is — Danesbury, Pottersheath — never run a motor that hasn't run yet. Leave the motor and the ignition off and phone 0333 366 0103; it is usually a drain and a thorough flush, done where the car is around Pottersheath. If it has run, stop as soon as it is safe then switch off. A bigger job, then, yet the identical opening step. Find the scenario below that matches yours, wherever around Hertfordshire it happened. ## Pottersheath forecourt: AdBlue in a diesel at the pump You are at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Anywhere around Pottersheath, then — BP, Tesco, or anywhere else nearby. What it means: this is the ideal location to find out. Still in the tank, with nothing drawn through: that's where the AdBlue is. Your move: stay out of the driver's seat, however much the pump needs freeing. Three jobs: a shove into a space with the staff helping, the receipt kept, and a call to us from where you stand. Emptying it there at the petrol pump is possible if it cannot be moved, since the equipment is explosion-proof. ## AdBlue in your diesel tank at home around Pottersheath For days the dashboard had been warning you. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look again at the cap. Drives close to Pottersheath Road see it as much as any other street. What it means: if you have not driven since, this is nearly as good as the forecourt. AdBlue doesn't mix with diesel; it sinks to the bottom of the tank and waits there. Overnight does not change that. Keep the keys indoors tonight — otherwise a person may take it off first thing — and phone us. We drain the vehicle on your drive, whether that is around Pottersheath or out in Rableyheath. Late-night drains beside a house are no problem: the pumps are quiet. ## On the road around Pottersheath with AdBlue in a diesel Rough running, smoke, lost power or a glowing dashboard started a mile or two beyond the top-up. Somewhere along Danesbury Park Road or heading towards St Albans — under 10 miles away. Meaning? Your pump has taken the AdBlue up. Mileage sets how far it goes: filter and pipework first, then the high-pressure pump and every injector. Each restart, like every mile, pushes it on. Do this: stop somewhere sensible, then turn the motor off. Pottersheath lies under a mile from the A1(M); there, pull off at the first junction instead of pressing on to the services. Don't restart the car to see if it has cleared; it will not have. Roughly what distance had it go? Say so when you call. ## AdBlue in the wrong tank of a hire, lease or company car You've just had the car for days. The AdBlue filler is right next to the diesel filler, which you didn't know, because your own car either has no AdBlue or keeps it somewhere else. Any driver, wherever in Hertfordshire, could make it. Put simply: an extra stage on top of the situations above, and those depend on whether it has run. Many hire and company agreements want the owner to approve work on the car. Do this: rental firm or fleet manager first, us next, because settling it early cuts time. Stranded by Woolmer Green Village Hall or outside Knebworth till someone answers, your vehicle remains switched off throughout. ## Pottersheath: unsure if it was AdBlue in the diesel tank? Sometimes the honest answer is "I think so". A faint ammonia-like smell hangs near the filler, the bottle feels too light, and which cap came off is a blur. Perhaps it happened in a hurry at the school gates at Oaklands Primary School, or on a friend's drive in Nup End Green. What it means: a little spilled around the filler does no damage to the motor. In the diesel tank, however, AdBlue harms it. Any AdBlue in the tank would be drawn in by starting the car, and the start wouldn't settle which it is in any case. What to do: treat it as if it went in. Don't crank it. Tell us what you saw on your phone. A clean tank looked at counts as a better outcome than an already-run one drained. ## What every AdBlue drain around Pottersheath has in common Whichever scenario you are in, this job starts the same way. Filling station, driveway, Robin Hood & Little John's car park or a street beside St Michael's — the van comes to your vehicle, and three answers come next: which liquid, what amount, and if it ran. Your price is given over the phone, ahead of anyone setting off, and those answers set the job. A thorough flush comes after this drain. With petrol it's standard; with AdBlue it's essential, because crystals form and some metals corrode, and neither washes out unaided. Fresh diesel is put in once the filter is flushed or replaced, and the car is finally checked. If the motor hasn't run, the majority of jobs take about half an hour once we're there. Starting the engine comes last. We confirm it runs properly on fresh diesel before leaving. Permanent damage is very unusual if it is caught early, and the entire job is done where the car is. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, nothing in advance. Dig out your insurance before we're en route: misfuelling cover is included in many policies. ## About Pottersheath Pottersheath is a small village in Hertfordshire, situated inland at an elevation of around 124 metres.
