AdBlue in the Diesel Tank in Downs Barn: What Now?
Everything turns on a single fact: whether the engine has been run after the AdBlue was added — far more than anything else. Over in Conniburrow or right around Downs Barn, an unrun motor should stay unrun. Leave your motor and your ignition off and call 0333 366 0103; it's normally a drain and a thorough flush, done where the car is around Downs Barn. Stop the moment you safely can and switch off, if it has been run. Stage one remains unchanged, even if the work grows.
Wherever across Buckinghamshire it happened, one of the situations below fits yours.
AdBlue in a diesel on a Downs Barn forecourt
The cap you opened was the wrong one — and you only notice it while you're standing at the pump, bottle or nozzle in your hand. Anywhere around Downs Barn, then — BP, Esso, or somewhere else close by.
Meaning? Spotting it here is the best it gets. Only your tank has AdBlue; not one component past it has taken it in.
Freeing the petrol pump is no excuse to start it — and so do not get back in. Get the staff to help pushing it into a space, save the receipt, then phone us from there. The equipment is explosion-proof and fine on a busy forecourt, so a vehicle that can't be pushed clear gets drained where it is at the pump.
At home around Downs Barn with AdBlue in your diesel tank
For days the dashboard had been nagging 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 once more at the cap. Driveways near Armourer Drive see it as much as any other street.
What it means: if you haven't driven since, this is almost as good as the forecourt. AdBlue does not mix with diesel; it sinks to the bottom of the tank and waits there. Overnight does not change that.
Keep the keys in the house tonight — or someone may take it away at breakfast — then call us. Our engineers drain the vehicle on your driveway, whether that's in Downs Barn or out in Neath Hill. Our pumping kit runs quiet enough that it won't wake the neighbours at night.
Drove off with AdBlue in a diesel in Downs Barn?
You filled up, set off, and a mile or two later your motor began to run unevenly, smoke, lose power or light up the dashboard. Somewhere on H4 Dansteed Way or else on the road towards Milton Keynes — under 3 miles away.
What it means: the fuel system has sucked the AdBlue in. Distance sets how far it goes: filter and lines first, then the injection pump and each injector. More miles, more starts: further it travels.
Do this: pull up anywhere sensible, then switch your engine off. Leave by the first junction — not the services further along — if you're on the M1, under 3 miles from Downs Barn. It will not have cleared, and so there is no sense starting it again to find out. About how far did it go? Say so when you phone.
A hire or company car with AdBlue in the wrong tank?
You have just had this vehicle a week. Your own motor either does without AdBlue or puts it somewhere different, so nothing warned you the AdBlue inlet sits right next to the diesel. Any driver, anywhere in Buckinghamshire, could do it.
Meaning? Whatever applies above counts here — run or not — and one extra stage. Plenty of hire and fleet contracts need the owner's approval for work.
What to do: ring the hire firm or your fleet manager first, then us. That's faster settled before we turn up than after. If you're stranded in the car park at Milton Keynes Central, or by Milton Keynes Murugan Temple, while you wait for an answer, leave your car off.
Downs Barn: unsure if it was AdBlue in the diesel tank?
Occasionally the honest answer is "I think so". A slight ammonia-like whiff lingers around your filler, the bottle feels too light, and the cap you took off is a blur. The gates of Downs Barn School in a hurry, say, or a friend's driveway over in Campbell Park.
Meaning? Spills outside the inlet never reach the motor at all. Once it's inside your diesel tank, though, it does. Any AdBlue in that tank would be drawn in by firing up the car, and the start wouldn't settle which it is in any case.
Do this: behave as if it got in, and never start your motor. Ring and give the details: we would sooner find a clean tank than drain one after the motor has run.
Downs Barn: what each AdBlue drain has in common
Whichever situation you are in, this job starts the same way. We come to the car, whether it is on a forecourt, a driveway, the car park at The Eager Poet or a side street close to Barn Ecumenical Church, and ask three things: what went in, about how much, and whether your engine has run. Your price is given on the call, ahead of anyone setting off, and the answers set the work.
Then that tank is drained and the fuel system rinsed thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not rinse out on its own. Next comes the fuel filter — flushed, or swapped when needed — then clean diesel, and a test of the vehicle. Where your motor has not run, allow roughly half an hour once we arrive, in most jobs.
Our engineers fire it up last. Our check that it runs correctly on fresh diesel comes before our engineers go. We do the entire job where your car is, and lasting damage is very rare when it has been spotted early. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of policies include misfuelling, so check yours while the van travels.
