AdBlue in the Diesel Tank in Wooburn: What Now?
Has the engine turned over since the AdBlue went in? That one question settles nearly everything else from here. Wherever your vehicle stands — Widmoor, Wooburn — don't run a motor that has not been started yet. Normally that is emptying and thoroughly cleaning it right there around Wooburn — and so leave the ignition and engine off and ring 0333 366 0103. Already run? Pull over once safe, then turn it off. A bigger job, then, but the same first step.
Find the situation below that matches yours, wherever in Buckinghamshire it happened.
AdBlue in a diesel on a Wooburn forecourt
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. Somewhere in Wooburn, then — BP, Shell, or somewhere else close by.
What it means: this is the best spot to find out. Still inside that tank, and no fuel drawn onwards: that is where the AdBlue is.
Next: avoid the temptation to start it just to move away from the pump. Ring us from the forecourt after the vehicle sits in a space — the attendants will lend a hand to roll it — and keep the receipt. If it can't be moved, it can be emptied at the petrol pump: the equipment is explosion-proof and fine on a busy forecourt.
AdBlue in your diesel tank on a Wooburn drive?
The warning light had been on for days. A bottle from the garage, tipped in at the drive — and it's only by the bin that the cap got your eye. Homes just off Town Lane are hit as often as everywhere else.
The point: zero miles since leaves it nearly as good to spotting it at the pump. At the bottom of that tank is exactly where AdBlue waits, since it will not mix with diesel — and a night passing makes no difference.
What to do: leave the keys inside the house so nobody moves the car in the morning. Then call. Your driveway is where it is emptied, be it around Wooburn or Cores End. Even at night, the pumps are quiet enough for a driveway.
AdBlue in a diesel and already driving around Wooburn?
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. Butterfield, perhaps, or the route towards St Albans — a run of under 25 miles.
The point: the system has drawn AdBlue in by now. Through your filter, along the pipework, and — the further the mileage — on into the injection pump and every injector. Each mile and each restart takes it further.
Pull in somewhere safe — that's the next job — then switch it off. Service stations farther along are too far: from the M40, under 3 miles out of Wooburn, use the first junction. Starting it again to check achieves nothing — AdBlue never clears on its own. About what distance did it go? Say so when you call.
Hire, lease or company car with AdBlue in the wrong tank
You've just driven the vehicle a week. The AdBlue filler sits right beside the diesel one, which you didn't know, since your own vehicle either has no AdBlue or keeps it somewhere else. Wherever you happen to be in Buckinghamshire, any motorist could be caught.
In short: an extra stage on top of the cases above, and those turn on whether it has run. The owner often has to sign off the work, under plenty of rental and company agreements.
What to do: ring the hire firm or your fleet manager first, then us. That is faster settled before our engineers arrive than after. Hanging on for a reply in the car park at Bourne End, or beside St Paul's Church? Keep the engine off meanwhile.
Unsure about AdBlue in your diesel tank around Wooburn?
Sometimes the honest answer is "I think so". A slight ammonia-like whiff hangs near your filler, the bottle seems too light, and the cap you took off is hard to recall. The gates of St Paul's Church of England Combined School, Wooburn in a hurry, perhaps, or a friend's driveway over in Wooburn Common.
Meaning? Drips outside the inlet never reach your engine at all. Once it is inside the diesel tank, though, that changes. Any AdBlue in your tank would be drawn in by starting your car, and the start wouldn't settle which it is in any case.
What to do: treat it as if it went in. Don't crank it. Describe what you saw on your phone. A clear tank checked counts as a happier result than a run one drained.
What each AdBlue drain around Wooburn has in common
Whichever scenario you are in, the job starts the same way. Our engineers come to your car, whether it is on a forecourt, a drive, the car park outside The Old Bell or a side street close to The United Reformed Church Cores End, and ask three things: what went in, roughly how much, and whether the engine has been run. Replies shape the work; the quote follows on the call while no one has set off yet.
AdBlue crystallises and is corrosive to certain metals used in fuel systems, and so it won't wash out on its own; that is why a full flush, after this drain, matters far more here than with petrol. Next is your filter — cleaned, or swapped when necessary — then clean diesel, and a test of your car. Most unrun vehicles are a half-hour visit from the moment our technicians get there.
Last, our engineers fire it up. Our technicians make sure it runs smoothly on new diesel before leaving. When it's spotted quickly, the car very seldom has lasting damage, and the whole job happens where it is. Nothing is taken upfront, settlement is made on the day, and you receive what your insurer asks for: an engineer report plus a VAT invoice. Dig out your insurance before we're en route: misfuelling cover is included in many policies.
