AdBlue in the Diesel Tank in Winscombe? Keep It Switched Off

Engine off, ignition off: that is how you begin if AdBlue has gone into your diesel tank. AdBlue is urea mixed in water. The trouble begins once it is pulled through the pump — it will not ignite, and it won't blend with diesel. Caught before the engine has run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is around Winscombe. Before you do anything else, call 0333 366 0103.

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

To do:

  • Remove the keys, which stops someone switching the electrics on.
  • Hazards on, if moving traffic is at all near.
  • Hold on to the till receipt or the empty bottle, so you can tell us what got in and roughly how much.
  • The van locates you quickest with a postcode starting BS25 1, or just the name of a street close by, so phone from the car.

Do not:

  • No starting the motor — not briefly, not to reposition your car.
  • Many diesels run their fuel pump the moment your ignition goes on, and so leave the vehicle off.
  • Do not top up with diesel to thin it. AdBlue doesn't mix in diesel; it separates out.
  • Even a short stretch down Woodborough Road is too far to drive the car.
  • Emptying your tank on your own by the road isn't one to try.

The attendants on duty at any Winscombe filling station — the Texaco included — will normally help rolling it clear if you ask. On your own driveway, do not move it at all.

AdBlue in a diesel tank: what it does

The engine isn't what AdBlue is made for; the exhaust is. From a separate tank it goes straight to the exhaust, treating what your engine emits. Nothing in a fuel pump is made for this fluid — and no part of that was meant to travel through one.

Inside a diesel tank it behaves very differently from fuel. It does not mix in. It sinks, since it's denser than diesel, and settles down where the pickup draws its supply from. Easiest of all: one that had AdBlue in Hale Coombe overnight and has not been started since. The liquid sits at the foot of that tank, untouched — though it will be the first thing through if the motor runs, before any diesel at all.

It does 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's corrosive to some of the metals a fuel system is made from, so it keeps running on the parts it reaches for as long as it remains there. If the AdBlue has reached the pipework, leaving it till morning around Winscombe leaves it worse. Inside the tank only, time does nothing. Then there is the water: it brings no lubrication to the parts that rely on it most — the high-pressure pump and every injector.

Draining AdBlue from a diesel tank in Winscombe

Why AdBlue in a diesel is frequently more serious than petrol

Top up a diesel with petrol by mistake over at the another forecourt nearby, and the issue is diluted fuel. Harm only comes from running on it. Blended into the diesel and left in the tank, it causes none.

With AdBlue in a diesel, the fluid itself is simply the wrong one. It can't just be run through, because it does not burn. Whether your car is in Winterhead or the centre of Winscombe, turning it over "to see" does more harm in this case than nearly any other error, and the flush matters more. The reasons: it won't stay blended, so diluting it is impossible; and crystals and corrosion outlast the following tankful.

As with petrol, there's good news. If the motor has not run, the AdBlue is still in the tank, and the tank is the easiest part of a fuel system to clear, wherever across Somerset the car is standing.

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

It is not on purpose. Plenty of vehicles have the AdBlue inlet alongside the diesel inlet, occasionally behind a single flap, and muddling them up is easy in poor light. A bottle picked up while driving home and poured in outside the house, instead of at the forecourt, is the usual story.

It tends to happen in a couple of familiar ways. A warning light comes on during the school run, and the top-up occurs in a hurry outside Winscombe Primary School. Close to Hillyfields Way, a driver pours a bottle in on that drive after work. Or the vehicle is topped up in the car park at The Woodborough Inn, in poor light, by a person who has never opened that flap before.

It occurs most in the cars motorists know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol. An identical mistake, an identical first response — keep it switched off — wherever you are in Winscombe or the rest of Somerset.

Already started the engine with AdBlue in the diesel tank around Winscombe?

If so, the AdBlue is no longer in that tank. The filter and pipework have had it pulled through, and some running time takes it on to the injection pump and each injector.

You may see your engine running roughly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from King's Wood or halfway across Winscombe. No restarting to check: stop once safe, then switch everything off. Each start pulls more of it through.

If you were on the M5, under 3 miles from Winscombe, come off at the next exit and stop somewhere sensible rather than pressing on.

Mileage matters: each mile carries the AdBlue further in, so heading towards Wells, under 15 miles away, gives a far larger job than hopping across Winscombe to the car park by Winscombe Library. Tell us roughly how far it had come.

There's more to flush once your engine has run, and our engineers do all of it where the car has come to a stop. Very rarely does it leave lasting damage when it is noticed quickly.

Winscombe: how AdBlue is emptied from a diesel

The vehicle stays put, whether that's a street near Winscombe Community Centre, a drive, a layby or a filling station in Winscombe, and the van travels to it. Before anything else our engineers ask what went in, roughly how much, and if the motor has been run, since those replies determine the work.

Right there, your tank is then emptied, and all of the polluted diesel and the urea leave as one. The fuel system is rinsed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. A test of the car comes last, once clean diesel goes in and your filter is flushed or, where needed, replaced. The majority of these jobs are a half-hour visit once our engineers get there, if the motor has not run. Low-noise enough for use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.

Bleeding the system with new diesel comes at the end. Then our technicians start the car and you head off, whether from a parking space outside Worle or a driveway in Winscombe. Our technicians make sure it runs properly on fresh diesel before we go. We do it all wherever the car has ended up, and it never has to go to a workshop. Insurers ask for a VAT invoice and an engineer report, and both come at the end.

About Winscombe, briefly

Winscombe is a village in Somerset, situated inland at an elevation of 41 metres, and is located near the villages of Woodborough, Sidcot, and Sandford Batch. Winscombe has a population of approximately 1632 residents and is characterized by predominantly detached housing. Winscombe is about 10.9 miles from the city of Wells and 117.3 miles from London, making it a rural community with some distance from major urban centres. Winscombe sits in a scenic area of the South West region, with its own distinct identity within the local landscape.

AdBlue drains across Winscombe and Somerset

Woodborough, Sidcot and Sandford Batch are among the towns around Winscombe that the same vans serve, along with much of Somerset further out, throughout the BS postcode area. If you are near a border, or somewhere hard to describe, ring and ask rather than assuming.

No moving is needed. In Winscombe, a rural village, a mobile service works: your car is emptied on the spot, whether in a driveway, a residential street, a car park or a filling station.

Winscombe: what AdBlue in a diesel tank costs to fix

No single price could be fair, since each job differs. Whether the engine has been running, and for how long, comes first in what moves the price. How much AdBlue was put in comes next, and then the position of your car, because an open drive is simpler for a van to get to safely than a tight gap behind St James Church.

What went in, what quantity, and if it ran: each Winscombe enquiry begins with exactly those, ahead of a quote, never after. Given them, a range narrows to a single firm figure.

Priced by phone before the engineer heads out, the job is settled that day — card or phone, nothing in advance. Check your insurance whilst we're on the way: many carry misfuelling cover.

In Winscombe and still alongside your car?
