AdBlue in the Diesel Tank in Oakfield, and What to Do Next
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 got in. If it hasn't, keep it that way, whether the vehicle is in Oakfield itself or out in St Ippolyts. Ring 0333 366 0103 with the ignition and engine both off. In Oakfield, such a case is generally drained and flushed on the spot. When your motor has been run, pull in safely first, then switch it off. Stage one remains unchanged, even though the job grows.
Below: the situations our engineers meet, anywhere in Hertfordshire. Pick the one that fits.
At the pump around Oakfield: AdBlue in a diesel
You are at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Possibly you are at the BP, possibly at the Esso, possibly somewhere else in Oakfield.
Meaning? Finding out on the forecourt is the best it gets. No pump has pulled it in, so the AdBlue sits only in the tank.
What to do: don't get back in and start the vehicle to clear the petrol pump. Phone us from the forecourt after the vehicle sits in a bay — the attendants will help roll it — and save the bottle. Can't move the vehicle beside the petrol pump? Our explosion-proof equipment keeps a live forecourt safe, so it can be drained in place.
AdBlue in your diesel tank on a Oakfield drive?
The warning light had been on for days. A bottle bought at the shop, emptied in at the driveway — and it was only by the recycling that the cap caught a second look. Just off Aston Rise is not different from anywhere.
What it means: if you have not driven since, this is nearly as good as the forecourt. Being unable to mix, AdBlue settles low inside the tank and waits. A night parked changes nothing.
What to do: leave the keys inside the house so no one moves your car in the morning. Then call. We drain it on your driveway, whether that is in Oakfield or out in Sunnyside. The pumping kit works quiet enough not to disturb the street at night.
Set off with AdBlue in a diesel in Oakfield?
Lumpy running, smoke, falling power or a glowing dashboard arrived a short way after the fill. Perhaps it was on Oakfield Avenue, possibly on the way out towards St Albans, under 15 miles away.
The upshot: your system has pulled AdBlue in by now. Mileage decides how far it gets: filter and lines first, then the injection pump and every injector. More miles, more restarts: deeper it goes.
Do this: stop anywhere sensible, then switch your engine off. On the A1(M), under 3 miles from Oakfield, that means the next exit, not the services further on. Starting it again to test gets nothing — AdBlue doesn't clear on its own. Phone us and say how far you went.
Hire, lease or company car with AdBlue in the wrong tank
You've just driven this car a week. Unbeknown to you, the AdBlue and diesel fillers sit side by side here — unlike your own car, which has none or keeps it in another spot. Anywhere you are across Hertfordshire, every driver could be caught.
In short: an extra step on top of the situations above, and those depend on whether it's run. Many hire and company contracts want the owner to approve work on the car.
Next: ring the rental company or your fleet manager first, then us — sorting it before our arrival is quicker. Keep the vehicle switched off as the answer arrives, whether you are parked at Hitchin or near St John's Community Centre.
Unsure about AdBlue in the diesel tank in Oakfield?
Now and then, "I think so" is the most you can truthfully say. Which cap came off, you cannot recall; meanwhile the bottle weighs lighter than expected, and ammonia lingers by the filler. A rushed top-up by the gates of Whitehill Junior School, or a call to a friend in Great Wymondley: both fit.
In short: a spill near your filler does the engine unharmed. AdBlue inside the diesel tank does. Any AdBlue in the tank will be drawn in by starting your car, and the start would not settle which it is in any case.
What to do: treat it as if it was put in. Do not start the car. Ring us and explain what you saw; we would rather check a tank that turns out clean than drain one that has already been run.
Each AdBlue drain around Oakfield shares these stages
The job opens the same way, whatever the situation. Our technicians come to the car, whether it is on a forecourt, a drive, the car park outside The Orange Tree or a side street near Walworth Road Baptist Church, and ask three things: what went in, about how much, and if the engine has run. Replies shape the job; the price follows by phone whilst nobody has left yet.
A thorough flush comes after the drain. With petrol it is standard; with AdBlue it's crucial, because deposits build up and some metals corrode, and neither washes away unaided. Clean diesel goes in after your filter is cleaned or changed, and the car is then checked. Most unstarted cars are a half-hour job from the moment our engineers turn up.
Lastly, we fire it up. Our engineers confirm it runs properly on new diesel before leaving. The entire job is done where the vehicle is, and when it is spotted soon, permanent damage is very uncommon. For your insurer: an engineer's report and the VAT invoice. For you: payment that day, nothing in advance. Worth knowing: lots of insurers include misfuelling cover, so a check of your documents while you wait pays.

Oakfield and Hertfordshire: AdBlue drains across the area
Oakfield is a residential suburb, and the same vans that cover it work the places around it too, Ashbrook and Hitchin Hill among them, across the SG postcode area. A postcode starting SG4 9 is the quickest way to tell us where you are.
Whether the car is on a lay-by on the way to Halsey Green or in a car park in the middle of Oakfield, it does not need to shift. The van drains it in place. Assuming doesn't help near Queen Mother Theatre, close to a county line or anywhere hard to pin down; ring and ask.
