AdBlue in a Diesel Tank in Fromefield? Don't Start It

Engine off, ignition off: that's where you start if AdBlue has got into the diesel tank. Water with urea mixed in it: that's AdBlue. Being water-based, it will not burn and won't blend with diesel; trouble just comes once the pump starts drawing it. A drain and a thorough flush, done where the car is in Fromefield, is usually all AdBlue in a diesel tank needs — if it's caught before the engine has run. Before you do anything else, ring 0333 366 0103.

AdBlue in the diesel tank around Fromefield: the first few minutes

To do:

  • Remove the keys, which prevents anyone turning the power on.
  • Put the hazard lights on if you are at all near moving traffic.
  • Keep the till receipt or the empty bottle, so you can tell us what got in and roughly how much.
  • Call right where you are. Say a BA11 2 postcode or the closest street name, and no one has to hunt for you.

Not to do:

  • Moving the car just a short way is no reason to fire up your motor.
  • Don't switch your ignition on. On many diesels that alone runs the fuel pump.
  • Don't top up with diesel to dilute it. AdBlue does not dilute in diesel; it separates out.
  • Keep it where it is instead of driving it anywhere, even a short way up Berkley Road.
  • No emptying it yourself, at all, on the roadside.

Moving your vehicle away from the island is a job for staff to help with, whichever Fromefield forecourt you are on, the Texaco or any other. At home, the vehicle stays exactly as it is.

AdBlue in a diesel tank: what it does

Not the engine but the exhaust is where AdBlue belongs. From a separate reservoir it goes directly to the exhaust, cleaning what your engine lets out. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

Tipped in with the diesel, it stays apart instead of mixing — quite different from fuel. It's heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup pulls fuel from. Easiest of all: a vehicle that got AdBlue in Berkley Down overnight and has not been started since. The AdBlue sits at the base of the tank, undrawn — but it would be the first thing through if the motor starts, before any diesel at all.

It causes two kinds of harm from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps labouring on the parts it gets to for as long as it stays there. Where the AdBlue is in the lines, waiting overnight in Fromefield leaves it worse. Inside the tank only, waiting costs nothing. Water lubricates nothing. The high-pressure pump and each injector depend on diesel running past them, and so the water content damages them in its own right.

Draining AdBlue from a diesel tank in Fromefield

Why AdBlue in a diesel is frequently more serious than petrol

Fill a diesel with petrol in error at the Asda, and the problem is thinned fuel. It mixes with the diesel, and whilst it's inside that tank it does no harm; the harm comes from running the engine on it.

With AdBlue in a diesel, the liquid as such is simply the wrong one. Not burning, it can't just be run through. Crystals and corrosion stay through the next fill, and AdBlue separates again from the diesel, and so thinning it won't help. Hence the flush matters more, and trying the engine "to see" does more harm here than nearly any other slip — in Keyford or the centre of Fromefield equally.

The good news is the same as with petrol. Clearing a tank is the easiest part on any fuel system, and with no running, the AdBlue remains in there — wherever in Somerset the car has stopped.

AdBlue in a diesel tank in Fromefield: how it ends up there

No one means to do it. The AdBlue filler on plenty of motors rests right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. It mostly occurs outside the house, from a bottle grabbed on the journey home, rather than at the forecourt.

Usually, it occurs in one of a couple of familiar ways. Rushing, outside Hayesdown First School, after a warning lamp came on during the school run, a parent tops up the vehicle. In the evening, a bottle goes in on a drive close to St John's Road. Or a driver new to that flap tops up the vehicle after dark, parked in the car park outside The Vine Tree.

It comes up most in a hire car, a new car, a fleet vehicle, or the spare motor in a family with both fuels — the vehicles people know the least. Wherever you are around Fromefield or the remainder of Somerset, it's the same slip and the same first answer: leave the car off.

AdBlue in your diesel tank in Fromefield, and the motor started?

The AdBlue has left the tank, then. It's been pulled through your filter and the fuel lines, and if your engine ran for any time, it has got to the high-pressure pump and your injectors.

Expect lumpy running, exhaust smoke, falling power, lights on the dash, or a stall — coming back from Rodden Meadow, perhaps, or midway across Fromefield. Stop when safe. Switch off. Keep the car off rather than testing it again. Every start pulls more of that through.

Fromefield sits under 25 miles from the M4; if you were on it, exit at the first junction and pull up safely instead of carrying on.

Hopping across Fromefield to the car park by Frome Leisure Centre is one thing; heading for Bath, under 15 miles away, is another, because each mile carries the AdBlue further in. So mileage counts. Let us know roughly how far it had come.

Once the motor has been run, the flush covers more, and all of it is done where the car has stopped. Noticed quickly, it very seldom leaves permanent damage.

Clearing AdBlue in a diesel in Fromefield: what it takes

We come to the vehicle, wherever it has stopped around Fromefield: a side street near The Merlin, a drive, a lay-by or a forecourt. The job rests on three replies, which our engineers ask for before all else — what got in, the quantity, and whether your engine has turned over.

Right there, your tank is then drained, and both the contaminated diesel and the urea come out at once. The system is flushed thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. Testing your car follows last, after clean diesel goes in and your filter gets flushed or, if necessary, replaced. If your motor has not run, most jobs take about half an hour once our technicians are there. The equipment is explosion-proof, and so a busy forecourt is no issue, and it's hushed enough for a residential street after dark.

New diesel goes in to prime the system, and that's the last step. You set off as soon as our technicians have started it, and it makes no difference whether your car is on a drive in Fromefield or in a bay by Frome. It's checked on clean diesel to be sure it runs correctly before we head off. The entire job is done where your car is, so it never has to be taken to a garage. Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

About Fromefield and where it is

Fromefield is a riverside locality in Somerset, situated near the town of Frome and approximately 10 miles from the city of Bath. Fromefield lies at an elevation of around 88 metres, with semi-detached housing being the predominant type of accommodation in the area. Fromefield is part of a larger network of settlements along the river, including nearby Easthill and Stonebridge.

Fromefield and Somerset: AdBlue drains across the area

AdBlue jobs in Fromefield go to teams that cover the places around it — Easthill, Stonebridge as well as Frome — and most of Somerset beyond, across BA postcodes. If you're close to a boundary, or somewhere hard to describe, ring and ask instead of assuming.

No towing is needed. In Fromefield, a small village, a van that comes to you fits: the vehicle is emptied where it stands, whether in a driveway, a residential street, a parking area or a filling station.

What does AdBlue in a diesel tank cost to sort out around Fromefield?

There's no honest single quote, since the jobs are not the same. Three things move the cost: whether the motor has been running and for how long, how much AdBlue went in, and where the car is. That last one turns on whether our van can get to it safely, and an open drive is easier than a tight spot behind Cheese and Grain.

What got in, how much, and if the engine ran: each Fromefield enquiry opens with precisely those, ahead of any quote, not after. Given those replies, a range shrinks to a single firm figure.

You hear that quote by phone, before anyone heads out, and you pay on the day, by card or by phone, with nothing upfront. Many insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.

In Fromefield and still alongside your car?

In that case, do nothing — that is the best step there is. Keys out; engine and ignition off. Call 0333 366 0103 then tell us it is AdBlue, roughly how much, and if it's run. Petrol in Diesel takes it from there, in Fromefield or anywhere in Somerset.
