What Now? AdBlue in the Diesel Tank in Thornborough
Has your engine turned over since the AdBlue got in? That single question settles nearly everything about what comes next. Not started yet? Then keep it that way, wherever the vehicle sits — Thornborough or Adstock. Ring 0333 366 0103 with your ignition and engine both off. In Thornborough, that is typically drained and cleaned where it stands. Already run? Pull over when you safely can, then turn it off. The job is bigger, yet the first stage is the same.
Below: the cases our technicians see, anywhere across Buckinghamshire. Pick the one that fits.
Thornborough forecourt: AdBlue in a diesel at the pump
Just now, nozzle yet in your hand, you realise that the cap you took off was the wrong one, there at the petrol pump. It could be the Shell, or the Tesco, or another station around Thornborough.
Meaning? Finding out here is the best it can be. Still inside your tank, with no fuel drawn onwards: that is where the AdBlue sits.
Next: resist the temptation to fire it up only to free up the petrol pump. Ring us from the forecourt once your vehicle is in a bay — the staff will help roll it — and keep the bottle. Draining it there at the pump is possible if it can't be moved, because the equipment is explosion-proof.
Thornborough, at home: AdBlue in your diesel tank
Days had passed with the dash light on. A bottle from the shop, emptied in at the driveway — and it was only at the recycling that the cap caught your eye. It occurs on driveways just off Back Street as regularly as anywhere.
In short: if the vehicle hasn't moved since, it's nearly equal to finding out at the forecourt. Being reluctant to mix, AdBlue drops low in that tank and waits. One night parked changes nothing.
Next: the keys indoors, and so no one takes your vehicle off at breakfast. Then, ring. Thornton or Thornborough: wherever your drive sits, that is where it gets cleared. Night-time clears beside a house are fine: the pumps are quiet.
AdBlue in a diesel and already driving around Thornborough?
Topped up, pulled away, and before long the engine was running unevenly, blowing smoke, down on power, or flashing up your dash. The Green, perhaps, or the way towards Milton Keynes — a trip of under 10 miles.
What it means: your fuel system has sucked the AdBlue in. It has been through the filter and the fuel lines and, the further you went, into the high-pressure pump and the injectors. It goes deeper with each extra mile driven and each restart.
Next: pick a sensible spot, pull in, then switch the engine off. Leave at the next junction — not the services beyond — if you're on the M1, under 10 miles from Thornborough. It will not have cleared, and so there's no point starting it again to find out. Let us hear the mileage covered as you ring.
AdBlue in the wrong tank: hire, lease and company motors
A week back, it was new to you. Your own vehicle either has no AdBlue or keeps it elsewhere, and so nothing warned you the AdBlue inlet sits just next to your diesel. Across Buckinghamshire, no one is safe from it.
Meaning? Whatever applies above applies too — run or not — plus one further step. Plenty of rental and fleet agreements need the owner's sign-off before repairs.
Sorting it before the van arrives is faster, so phone the rental company or your fleet manager, and then us. If you are stranded in the car park at Milton Keynes Central, or by St Mary, while you wait for an answer, leave the car off.
AdBlue in your diesel tank? Not sure, in Thornborough
Honestly, the best answer may be that you think so. The bottle is lighter than it should be, there's a faint smell of ammonia around your filler, and you cannot remember which cap you took off. Possibly it happened in a hurry at the school gates at Thornborough Infant School, or on a friend's drive in Great Horwood.
In short: a spill round your filler does your motor no harm. Once it's inside your diesel tank, though, it does. If there is AdBlue in your tank, turning on the vehicle will pull it in, and it would not tell you which either.
Next: assume it got in, and leave the motor off. Ring us and explain what you saw; we'd rather check a tank that turns out clean than drain one that has already been run.
What each AdBlue drain in Thornborough has in common
Whatever the case, one start is used. Anywhere your vehicle is — the pub in the village's car park, a road by Thornborough Mounds, a drive, a filling station — our van arrives and we ask about the fluid, the amount, and whether your motor has turned over. Over the phone, ahead of dispatch, you are told the price, and those replies shape the work too.
Then that tank is emptied and the fuel system flushed thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't rinse out on its own. Clean diesel goes in after your filter has been flushed or changed, and your car is then tested. Most unrun vehicles are a half-hour visit after the moment our engineers arrive.
Our engineers start the car last. Our test that it runs smoothly on new diesel comes before we head off. Long-term damage is very unusual when it's caught quickly, and the whole job is done where the car is. Payment comes on the day, never upfront. For your insurer, there is a VAT invoice plus a report from the engineer. Many insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.
