Middle Leigh: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has gone into your diesel tank, keep your engine off then leave the ignition off. Urea mixed in water is all AdBlue is. It doesn't burn, it doesn't mix with diesel, and the damage it does starts when the fuel system draws it in. Caught before your engine has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is around Middle Leigh. Before you do anything else, ring 0333 366 0103.

Those opening minutes: AdBlue in the diesel tank in Middle Leigh

To do:

  • So no one can turn the ignition on, pull your keys away.
  • Put the hazards on if you're at all near moving traffic.
  • Which product, and roughly how much amount? Save the bottle or the till receipt, and our technicians can know.
  • Call just where you are. Say a BA16 0 postcode or the closest street sign, and nobody has to search for you.

Don't do these:

  • Shifting the vehicle even a few yards is no reason to fire up your engine.
  • Your ignition remains off: on many diesels, switching it on is enough to start the fuel pump.
  • Don't top up with diesel to dilute it. AdBlue does not dilute in diesel; it separates out.
  • Keep the vehicle where it is instead of driving it anywhere, even a short way down Leigh Road.
  • No emptying it yourself, either, on the verge.

Get the attendants to help you roll your vehicle off the pumps if you are at a forecourt around Middle Leigh, whether it's the Sainsbury's or elsewhere. On the drive, the car stays exactly as it was left.

AdBlue in a diesel tank, and what it does there

AdBlue is made for the exhaust, not the engine. From a separate reservoir it is fed straight to the exhaust, cleaning what your motor lets out. A fuel pump isn't made to cope with it, and AdBlue was never supposed to go through one.

Inside a diesel tank it acts really differently from fuel. It does not mix in. The pickup sucks fuel from the deepest part of that tank, and that is just where AdBlue settles: as it is heavier than diesel, it sinks. When the system runs, the AdBlue is first to go through. Before then it sits underneath your diesel, and that is how a vehicle topped up in Street yesterday and not switched on remains the straightforward one, as long as nobody touches your key.

From there it causes two kinds of damage. What remains once the water goes is urea, which turns into crystals: they lodge in narrow passages and block filters. On top of that, it eats at some metals in the fuel system, and keeps going till it is cleared out. By daybreak, a car sitting in Middle Leigh with AdBlue in its lines grows worse; where it is only in the tank, nothing changes. The water in it causes damage of its own: the high-pressure fuel pump and your injectors depend on diesel to lubricate them, and water offers them nothing.

Draining AdBlue from a diesel tank in Middle Leigh

Petrol or AdBlue in a diesel: why AdBlue is commonly worse

Put petrol in a diesel at the Shell and you have a fault of thin fuel. No damage comes while it stays unused, mixed into your diesel — only once your motor works on it.

AdBlue in a diesel is a different problem: not thin fuel, yet no fuel at all. It doesn't burn, so it can't just be run through. Whether your car is in Stone Hill or the centre of Middle Leigh, firing it up "to see" costs more with AdBlue than nearly any other mistake, and the flush counts more. Why: it will not stay blended, and so diluting it fails; and crystals and corrosion survive the next fill.

The good news is the same as with petrol. Anywhere around Somerset your vehicle has stopped, an unstarted motor means the AdBlue yet inside the tank: the simplest part of a fuel system to empty.

How does AdBlue end up in a diesel tank around Middle Leigh?

It's not on purpose. Many cars have the AdBlue cap alongside the diesel one, now and then behind a single flap, and muddling them up is easy after dark. Usually it is never the filling station: a driver picks up a container heading home and pours it in at home.

The ways it happens are few and familiar. Hurrying, outside Hindhayes Infant School, after a warning lamp came on during the school run, someone refills the vehicle. Near Tannery Close, someone pours a bottle in at home in the evening. One more pattern: darkness, a pub car park outside The King Alfred, and a driver using that flap for the first time.

Hired cars, new motors, fleet vehicles, or the spare vehicle in a family with both fuels: the least familiar vehicles see it the most. Wherever across Somerset, Middle Leigh as well, the mistake does not change, and neither does the first response: leave it switched off.

Started the motor with AdBlue in the diesel tank in Middle Leigh?

Then the AdBlue has left your tank. Through the filter, along the pipework, and — given any running — on to the injection pump and each injector: that's where it has gone.

Expect rough running, smoke, falling power, lights on your dash, or a stall — coming back from Wraxhill Park, say, or part way across Middle Leigh. Pull over when safe. Turn off. Leave the vehicle off instead of restarting it to check. Each start pulls more of it through.

On the M5, under 10 miles from Middle Leigh, the next junction is where to exit, and somewhere safe is where to park — not carrying on.

How far it went counts. A few hundred yards across Middle Leigh to the car park by The Salvation Army - Street is a very different job from a run towards Wells, under 10 miles away, with the AdBlue reaching further into your system with every mile. Let us know roughly how far it had come.

Wherever your car came to a stop is where all of it gets done, even with more to flush after the motor has been started. Spotted quickly, it very rarely leaves lasting damage.

Middle Leigh: how AdBlue is drained from a diesel

Anywhere it has come to rest in Middle Leigh — a forecourt, a lay-by, a drive, a road beside Mission Church — our van comes to your vehicle. Which fluid went in, roughly the quantity, plus whether the engine has been run: our engineers ask first, because those decide the work.

On the spot, the tank is then drained, and all of the contaminated diesel and the urea leave as one. With AdBlue, more so than with petrol, flushing counts: the fuel system is cleaned all the way through because what remains won't flush out unaided. A test of your car comes at the end, after clean diesel is added and the filter is cleaned or, where necessary, swapped. Most of these jobs are a half-hour visit once our technicians turn up, provided your motor has not run. Explosion-proof pumps mean a busy forecourt sensible to work on, and they're quiet enough to spare the neighbours at night.

The last step is to prime the fuel system on new diesel. At that point our technicians start the car and you set off, whether from a parking space at Castle Cary or a driveway around Middle Leigh. The check before our engineers go is that it runs properly on fresh diesel. The whole job is done where the vehicle is, so it never needs to go to a garage. Your insurer will want an engineer's report and the VAT invoice — both yours once this job is done.

AdBlue drains across Middle Leigh and Somerset

What AdBlue in a diesel tank costs to put right in Middle Leigh

No single price could be honest, since each job is different. The price shifts first with how long, if at all, the engine has been running, and next with the amount of AdBlue that got in. After that it rests on where the car is and whether our van can reach it safely, which is easier on an open driveway than in a tight gap behind The Bayliss Centre.

For that reason, every enquiry from Middle Leigh opens by asking the same trio — what went in, how much, whether the engine ran — ahead of any figure. Those answers turn a range into a straight quote.

Priced by phone before the van sets out, it is paid for that day — card or phone, nothing in advance. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.
