Mynydd-bach: AdBlue in the Diesel Tank? Find Your Situation
What to do about AdBlue in a diesel tank comes down to one thing more than any other: whether your motor has been run since it was put in. Not started so far? Then leave it like that, whether the car sits — Mynydd-bach or Bullyhole Bottom. Leave the engine and the ignition off and phone 0333 366 0103; it is generally a drain and a thorough flush, done where the car is in Mynydd-bach. Pull over the moment you safely can then switch off, if it has already run. It's a bigger job, though step one doesn't change.
Below: the situations our engineers meet, wherever across Monmouthshire. Choose yours.
On a Mynydd-bach forecourt with AdBlue in a diesel
You are at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Possibly you're at the Texaco, perhaps at the BP, perhaps somewhere else in Mynydd-bach.
The upshot: of all places to notice, this is the best. No pump has drawn it through, so the AdBlue sits only inside that tank.
Freeing the petrol pump is no excuse to start it — and so don't get back in. Three things: a push into a space with the attendants assisting, the bottle kept, and a call to us from the forecourt. If it cannot be moved, it can be cleared at the pump: the equipment is explosion-proof and safe on a busy forecourt.
AdBlue in the diesel tank at home in Mynydd-bach
The warning light had been on for days. Only by the recycling, the empty bottle in hand, did you glance back at the cap you'd used at the driveway. It takes place on driveways just off Weyloed Lane as commonly as anywhere.
In short: if the vehicle hasn't been driven since, it's nearly equal to spotting it at the pump. On the floor of that tank is exactly where AdBlue stays, since it won't blend with diesel — and a night going by makes nothing of the difference.
What to do: leave the keys inside the house so no one moves your car in the morning. Then call. We drain it on your driveway, whether that is in Mynydd-bach or out in Shirenewton. The pumps are quiet enough to use outside a house after dark.
Mynydd-bach: drove off with AdBlue in a diesel?
A mile or two beyond topping up, the engine began playing up: rough running, smoke, lost power, warnings on the dash. Maybe it was on Blethyn Close, possibly on the way out towards Newport, under 15 miles away.
Meaning? Your fuel pump has sucked the AdBlue in. Mileage decides how far it goes: filter and pipework to begin with, then the injection pump and every injector. Every restart, like every mile, pushes it on.
Next: find a safe spot, stop, then turn your engine off. Mynydd-bach lies under 3 miles from the M48; on it, pull off at the next junction rather than pushing on to the services. Do not restart it to see if it has cleared; it will not have. Roughly what distance did it gone? Tell us as you call.
A hire or company car with AdBlue in the wrong tank?
You have had this vehicle barely a week. The AdBlue filler sits right next to the diesel filler, which you didn't know, since your own motor either has no AdBlue or keeps it somewhere else. Any driver, anywhere around Monmouthshire, might do the same.
In short: an extra stage on top of the cases above, and those turn on whether it has run. The owner often needs to approve any work, under many hire and fleet contracts.
Next: ring the hire company or your fleet manager first, and then us — sorting it before we arrive is faster. If you are stranded in the car park outside Chepstow, or by Itton Church, Saint Deiniol, whilst you wait for an answer, leave your car off.
Not sure it was AdBlue in your diesel tank, Mynydd-bach?
Truthfully, the best answer might be that you think so. A slight ammonia-like smell lingers around the filler, the bottle feels too light, and which cap came off is hard to recall. The gates of Tutshill Church of England Primary School in a rush, perhaps, or someone's driveway over in Mounton.
The upshot: the engine isn't hurt by some AdBlue spilled on the outside. Inside the diesel tank, by contrast, AdBlue damages it. Any AdBlue in your tank would be pulled in by turning on your car, and the start wouldn't settle which it is in any case.
What to do: treat it as if it was put in. Don't fire it up. Ring with what you saw: we would sooner find a clean tank than empty one after the engine has run.
Mynydd-bach: what every AdBlue drain has in common
Each case has the same opening to the job. Forecourt, drive, Tan House's car park or a road by Llanmelin Hill Fort — our van reaches your vehicle, and three questions follow: which liquid, what quantity, and if it ran. Answers shape the job; the quote comes on the call while no one has left yet.
AdBlue forms crystals and eats at some metals used in fuel systems, and so it does not rinse out on its own; that's why a full flush, after this drain, matters far more here than with petrol. Next is the fuel filter — cleaned, or replaced when needed — followed by clean diesel, and a test of your car. Most unrun vehicles are a half-hour visit after the moment our technicians arrive.
Starting the engine comes last. Our check that it runs correctly on clean diesel comes before our engineers leave. Permanent damage is very unusual if it is noticed quickly, and the entire job is done where the vehicle is. Payment comes that day, never in advance. For your insurer, you get a VAT invoice plus a written report from the engineer. Plenty of policies include misfuelling, and so look at yours as we head over.

Mynydd-bach and Monmouthshire: AdBlue drains across the area
Mynydd-bach is a village, and the same vans that cover it work the places around it too, Itton and Itton Common among them, across the NP postcode area. Quickest of all: a NP16 6 postcode for where you stand.
No moving is required, whether parked centrally in Mynydd-bach or in a lay-by heading to Shirenewton Recreation Association, and so keep it put. Our technicians drain it where it stands. Phone and ask instead of guessing when you're close to Earlswood and Newchurch West Memorial Hall, near a boundary, or anywhere awkward to pin down.
