Don't Start It: AdBlue in a Diesel Tank in Alperton

If AdBlue has got into the diesel tank, keep the engine off and keep your ignition off. AdBlue is urea mixed in water. Not like fuel, it neither ignites nor blends, and no harm happens until your engine pulls it round. In Alperton, AdBlue in a diesel tank caught before your engine runs normally means a drain and a thorough flush, just where the car is. First, phone us on 0333 366 0103.

AdBlue in your diesel tank in Alperton: the first few minutes

Things to do:

  • Take your keys out, and so no one switches the ignition on.
  • Put your hazards on if you're at all close to moving traffic.
  • Which product, and about what amount? Hang on to the bottle or the receipt, and our technicians can see.
  • Our van locates you fastest with a postcode starting HA0 1, or simply the name of a street nearby, and so phone from the car.

Not to do:

  • Don't start the engine, even for a moment to shift the car.
  • Switching the key to ignition by itself starts the pump running on many diesels. Skip it.
  • Do not top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.
  • Any driving at all is to be avoided, even a short stretch up Orchard Close.
  • By the road, don't try draining it yourself.

The staff on duty at any Alperton filling station — the Sainsbury's included — will usually lend a hand rolling it aside if you ask. On your own driveway, don't touch it at all.

What does AdBlue do in a diesel tank?

Meant for your exhaust, AdBlue has no business in the engine. Kept in a separate tank, it's injected into the exhaust to clean the gases. Nothing in an injection pump is made for this fluid — and none of that was intended to go that way.

Tipped in with the diesel, it keeps apart rather than mixing — quite different from fuel. It sinks, since it's denser than diesel, and settles down where the pickup takes its fuel from. Simplest of all: one that had AdBlue in Tokyngton overnight and has not turned since. The liquid sits at the base of that tank, untouched — but it will be first through once your motor starts, before any diesel at all.

From there it does two kinds of harm. What is left when the water evaporates is urea, which forms crystals: they settle in narrow channels and block filters. Worse, it eats at certain metals in the fuel system, and carries on till it is flushed out. By daybreak, a vehicle sitting around Alperton with AdBlue through its pipework gets worse; if it's only inside that tank, nothing changes. Water protects nothing. The injection pump and every injector need diesel flowing past them, and so the water content harms them in its own right.

Draining AdBlue from a diesel tank in Alperton

Why is AdBlue in a diesel frequently the bigger problem?

An issue of thinned fuel is what you get after filling a diesel with petrol from the Esso. No harm is done as long as it sits unused, blended into the diesel — only once the engine runs on it.

AdBlue in a diesel is a problem of the wrong substance altogether. Because it does not burn, running it through is not an option. Nor can it be watered down, because it separates again — and the next fill won't rinse away crystals or corrosion. So the flush counts for more here, and turning your key "to see", in the heart of Alperton or out in Park Royal, does more harm than almost any other slip.

As with petrol, there is good news. If the motor hasn't run, the AdBlue is still inside that tank, and that tank is the easiest part of a fuel system to clear, wherever across Greater London the car is sitting.

How does AdBlue end up in a diesel tank around Alperton?

After dark, two caps side by side — the AdBlue one and the diesel cap, now and then behind one flap — can appear the same. No one intends it; many designs invite it. A container bought when heading home and poured in at home, instead of at the forecourt, is the usual route.

Usually, it takes place in one of a couple of familiar ways. Halfway through the morning drop-off, the dashboard warns, and outside Lyon Park Primary School the top-up is hurried. In the evening, a container goes in on a drive close to Innovation Close. Or someone new to that flap refills your car after dark, stopped in the car park outside Heather Park.

It happens 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. Same slip, an identical first step — leave it switched off — anywhere you are around Alperton or the rest of Greater London.

Started the motor with AdBlue in your diesel tank in Alperton?

The AdBlue has left that tank, then. With any running time, it goes on to the high-pressure pump and each injector, after passing through the filter and lines.

Maybe coming back from Mount Pleasant Open Space, or midway across Alperton, your motor may run rough, smoke, drop power, flash your dash or cut out. Stop as soon as it is safe, switch off, and don't restart the car to check. With each start, more of that is pulled through.

Exit the M4, under 5 miles from Alperton, at the first junction and stop somewhere safe, rather than carrying on.

Mileage counts: each mile carries the AdBlue further in, so driving for Westminster, under 10 miles away, gives a much larger job than crossing Alperton to the car park by Alperton Baptist Church. Let us know roughly how far it had come.

Once your engine has run, the flush includes more, and all of it is done where your car has stopped. Caught early, it very seldom leaves long-term damage.

Alperton: how AdBlue is emptied from a diesel

The car stays put, whether that's a street near St James Alperton, a drive, a lay-by or a forecourt in Alperton, and our van comes to it. The work depends on three answers, which we ask for first — which fluid got in, the amount, and if your motor has run.

On the spot, your tank is then drained, and all of the polluted diesel and the urea leave at once. A full flush matters far more after AdBlue than with petrol, because what remains will not wash away on its own. A test of the vehicle comes last, after clean diesel is added and the filter gets flushed or, if necessary, replaced. About half an hour once we arrive is usual for most jobs when the motor has not run. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house after dark.

Fresh diesel goes in to prime your system, and that is the final step. You head off as soon as our technicians have fired it up, and it makes no difference whether the car is on a drive around Alperton or in a bay by Wembley Central. We make sure it runs correctly on clean diesel before we go. The entire job is done where the vehicle is, so it never needs to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come at the end.

About Alperton and where it is

Alperton is a suburban area in northwest London, situated on the banks of the Grand Union Canal at an elevation of around 50 metres. Alperton is located approximately 7.6 miles from central London and is close to nearby places such as Perivale, Wembley, and Stonebridge. Alperton has a population of around 17,882 people and is predominantly composed of flat dwellings. Alperton is a residential community with a mix of old and new buildings, including modern flat developments.

AdBlue drains across Alperton and Greater London

Perivale, Wembley and Stonebridge are among the towns near Alperton that the same vans reach, together with much of Greater London beyond, throughout the HA postcode area. If you're near a boundary, or somewhere hard to describe, ring and ask rather than assuming.

Alperton is a residential suburb, and a mobile drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, we drain it where it is, and so it never needs to be shifted to us.

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

Because the jobs vary, a flat figure would not be honest. What shifts the price is, first of all, whether your engine has been running and for how long; then how much AdBlue got in; and then where the car is and whether a van can reach it safely, which is easier on an open drive than in a tight space behind Shri Sanatan Hindu Mandir.

Ahead of a quote, never afterwards, every call from Alperton opens with the same three questions: the liquid, the amount, plus if the engine ran. Those replies shrink a range down to one figure.

You get that price by phone, before anyone sets off, and you pay on the day, by card or over the phone, with nothing upfront. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.

In Alperton and still alongside the vehicle?

In that case, touch nothing — that is the most helpful step there is. Keys out, engine off, ignition off. Ring 0333 366 0103: AdBlue, roughly how much, plus if it ran is all our engineers ask. Petrol in Diesel handles the rest throughout Greater London, Alperton included.
