Blackthorn: AdBlue in the Diesel Tank? Find Your Situation
What to do about AdBlue in a diesel tank depends on one thing more than any other: if your engine has been run since it went in. Wherever the vehicle stands — Rectory Farm, Blackthorn — never start an engine that hasn't run yet. Normally that means emptying and thoroughly flushing it on the spot in Blackthorn — so keep the key and engine off and call 0333 366 0103. Already started? Stop once safe, then turn it off. Step one remains the same, even if the job grows.
Match what happened to a situation from the ones below, wherever in Northamptonshire you happen to be.
AdBlue in a diesel on a Blackthorn forecourt
Imagine it: stood by the petrol pump, gripping the nozzle, you spot the cap you opened was not the correct one. Be it Tesco, Esso or somewhere else around Blackthorn, the case is the same.
The point: of all places to find out, the forecourt is the best. Still inside the tank, and no fuel pulled onwards: that's where the AdBlue is.
Next: avoid the urge to start it only to move away from the petrol pump. Ask the attendants to help you roll the vehicle into a parking bay, keep the receipt or the bottle, and phone us from the forecourt. Draining it there at the petrol pump is fine when it can't be shifted, since the equipment is explosion-proof.
AdBlue in your diesel tank on a Blackthorn drive?
On the dash, a warning had been lit all week. Picked up a bottle, tipped it in outside the house, recycled the empty — and at that point checked the cap again, after the fact. Right off Blackthorn Road is not different from anywhere.
In short: if your car has not moved since, it is almost as good as finding out at the pump. Being unable to mix, AdBlue drops low in the tank and waits. One night parked changes none of that.
Put your keys in the house tonight — or someone may drive it off first thing — and phone us. Overstone Lodge or Blackthorn: wherever your driveway sits, that's where it gets cleared. Even at night, our pumps are quiet enough for a residential street.
AdBlue in a diesel and already driving in Blackthorn?
Rough running, smoke, falling power or a glowing dashboard started a mile or two after the top-up. Anywhere on Cherry Lodge Road or on the road to Milton Keynes — under 25 miles away.
What it means: the fuel system has drawn the AdBlue in. The high-pressure pump and each injector get it too on a longer run, after the filter and lines have had it. Each restart, like each mile, pushes it deeper.
What to do: pull over where it is safe then switch off. Exit by the next junction — not the services further along — if you're on the M1, under 10 miles from Blackthorn. Do not restart the vehicle to see if it has cleared; it will not have. Roughly what distance did it gone? Say so as you phone.
AdBlue in the wrong tank of a hire, lease or company car
It's a vehicle you have had for a week. The AdBlue filler sits right next to the diesel one, which you didn't know, because your own vehicle either has no AdBlue or keeps it somewhere else. Anywhere you happen to be across Northamptonshire, any driver can be caught.
Meaning? Whatever case above counts here — run or unrun — and one extra step. Plenty of rental and fleet contracts require the owner's approval before repairs.
Next: phone the hire company or the fleet manager first, then us — sorting it before our arrival is quicker. Waiting for a reply at the car park outside Northampton, or beside Arlbury road Community Hub? Keep your engine off throughout.
Not sure it was AdBlue in the diesel tank, Blackthorn?
Now and then, "I think so" is all you can honestly say. Which cap was taken off, you cannot recall; but the bottle weighs lighter than expected, and ammonia hangs by your filler. Maybe it happened in a hurry at the school gates at Blackthorn Primary School, or on a friend's drive in Goldings.
In short: spillage near your filler does the engine no harm. A diesel tank with AdBlue in it is another matter. You can't tell which by turning the ignition, and doing so will draw in any AdBlue that is in that tank.
Your move: act as though it did, and don't start the engine. Phone with what you saw: we'd rather confirm a tank free of AdBlue than drain one after your motor has run.
What every AdBlue drain around Blackthorn has in common
Every situation gets the same start to the work. Three questions are asked when our engineers arrive — at a forecourt, a drive, a street beside Rectory Farm Community Centre or the car park at The Elwes Arms: the liquid, the amount, and if the motor has been started. Replies shape the job; the quote follows on the call while nobody has set off yet.
Draining your tank comes first, then a full flush — more important after urea than with petrol, because crystals and corrosion won't clear by themselves, no matter how long you wait. Finally are your filter, flushed or renewed as needed; clean diesel; and a test of the vehicle. Not started? In that case about half an hour on site is most jobs.
The last step is starting the car. Before we leave, it's tested to confirm it runs smoothly on new diesel. Permanent damage is very rare when it is spotted quickly, and the entire job is done where the vehicle is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Dig out your insurance while we arrive: misfuelling cover is built into plenty of policies.
