What Now? AdBlue in the Diesel Tank in Walkern
What to do about AdBlue in a diesel tank comes down to one thing more than any other: if your motor has been run since it was put in. If it has not, keep it that way, whether the vehicle is around Walkern itself or out in Chells Manor. Phone 0333 366 0103 with the key and engine both off. Across Walkern, such a case is typically emptied and cleaned on the spot. Pull over the moment you safely can and turn off, if it has been run. The job is bigger, but the first step is the same.
Below: the cases our engineers meet, wherever around Hertfordshire. Pick the one that fits.
On a Walkern forecourt with AdBlue in a diesel
Just at this point, bottle still in your hand, it dawns on you that the cap you took off was the wrong one, right at the petrol pump. Somewhere around Walkern, then — Pace, Sainsbury's, or somewhere else close by.
What it means: this is the best spot to find out. The AdBlue is in the tank and nowhere else. Nothing has drawn it in.
Do this: keep out of the driver's seat, even if the queue needs freeing. Ask the staff to help you roll the car into a parking bay, keep the receipt or the bottle, then call us from the forecourt. Our equipment is explosion-proof and fine on a busy forecourt, so a vehicle that cannot be pushed clear is drained right at the petrol pump.
At home in Walkern with AdBlue in the diesel tank
On your dash, a reminder had shown all week. Picked up a bottle, tipped it in outside the house, recycled the empty — and only then checked the cap again, after the fact. It takes place on driveways just off High Street as often as anywhere.
Meaning? As long as your car hasn't been driven since, it's second to the pump case. Diesel and AdBlue stay separate: the AdBlue settles to the floor of that tank and remains put, however long it waits.
What to do: leave your keys inside the house so no one moves the car in the morning. Then ring. We drain the vehicle on your driveway, whether that is in Walkern or out in Bassus Green. Night-time clears beside a house are fine: the pumps are quiet.
Walkern: set off with AdBlue in a diesel?
Filled up, pulled away, and before long your engine was turning unevenly, blowing smoke, down on power, or flashing up the dash. Somewhere along Finches End or else on the road towards St Albans — under 15 miles away.
The point: your system has drawn AdBlue through by now. The injection pump and each injector get it too on a bigger trip, once the fuel filter and pipework have it. Each mile and each restart takes it further.
Next: pick a safe place, stop, and switch the motor off. Leave by the first junction — not the services beyond — if you are on the A1(M), under 5 miles from Walkern. It won't have cleared, so there's no point restarting to find out. About how far had it go? Say so as you phone.
Hire, lease or company car with AdBlue in the wrong tank
You have had this car barely a week. Unbeknown to you, the AdBlue and diesel inlets are side by side here — unlike your own vehicle, which has no AdBlue or keeps it in another spot. Wherever you are around Hertfordshire, every motorist can slip up.
The point: exactly as above, divided by if it ran, but with an added stage. Many hire and company contracts require the owner's sign-off before repairs.
Do this: hire firm or fleet manager first, us next, since settling it early cuts time. Stuck near Walkern Sports & Community Centre or at Stevenage till the firm replies, the car stays switched off the whole time.
Not sure it was AdBlue in your diesel tank, Walkern?
"I think so" is often the most honest as it gets. What cap came off, you can't recall; meanwhile the bottle weighs lighter than expected, and a whiff of ammonia lingers by the filler. A rushed top-up by the gates of Walkern Primary School, or a visit to a friend in Ardeley: both fits.
Meaning? Drips outside the inlet never reach your engine at all. A diesel tank with AdBlue in it is another matter. Turning on your car won't tell you which, and if there is AdBlue in the tank it would suck it in.
Next: assume it went in, and keep the motor off. Ring and give the details: we'd rather find a tank free of AdBlue than drain one once the engine has been run.
What each AdBlue drain around Walkern has in common
No matter the situation, a single start applies. Our engineers come to the vehicle, whether it's on a forecourt, a driveway, the car park outside The White Lion or a side street near United Reformed Church, and ask three things: what went in, roughly how much, and whether your engine has run. The price comes over the phone, ahead of anyone setting off, and those answers set the work.
AdBlue forms crystals and is corrosive to some metals used in fuel systems, so it does not wash out unaided; that is why a full flush, after the drain, matters far more with AdBlue than with petrol. Clean diesel is put in once your filter is cleaned or replaced, and your car is finally tested. Most unstarted cars are a half-hour job after the moment we get there.
Finally, we start the engine. Our test that it runs properly on clean diesel comes before our engineers head off. We do the whole job where the vehicle is, and permanent damage is very unusual if it has been spotted quickly. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling, and so check yours as we head over.
