# AdBlue in the Diesel Tank in Hadleigh, and What to Do Next

What to do about AdBlue in a diesel tank depends on one thing more than any other: whether your motor has been run since it was put in.

Not run so far? Then keep the car that way, whether your car is — Hadleigh or Aldham.

Leave your engine and your ignition off and ring 0333 366 0103; it is normally a drain and a thorough flush, done where your car is around Hadleigh.

Pull over the minute you safely can and turn off, if it has been run.

It's a bigger job, though stage one doesn't change.

Find the situation below that matches yours, wherever across Suffolk it happened.

## AdBlue in a diesel on a Hadleigh forecourt

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.

Somewhere in Hadleigh, then — Gulf, another forecourt nearby, or somewhere else nearby.

Put simply: there is no better place to be to spot it.

Still inside that tank, with nothing drawn through: that is where the AdBlue sits.

What to do: don't get back in and fire it up to clear the petrol pump.

Have the attendants to help rolling it into a space, hold on to the bottle, then ring us right there.

Draining it right at the petrol pump is possible if it cannot be moved, because the equipment is explosion-proof.

## Hadleigh, at home: AdBlue in your diesel tank

For days the dash had been nagging you.

Bought a bottle, poured it in outside the house, binned the empty — and at that point checked the cap again, too late.

Driveways near Market Place get it as much as any other street.

What it means: if you haven't driven since, this is almost as good as the forecourt.

AdBlue does not mix with diesel; it sinks to the bottom of your tank and waits there. Overnight does not change that.

Next: stop an early-morning drive by putting your keys in the house, then ring us.

Out in Upper Layham or here in Hadleigh, the draining is done on your driveway.

The pumping kit works quietly enough that it won't wake the neighbours at night.

## Drove off with AdBlue in a diesel around Hadleigh?

You filled up, set off, and a mile or two later the engine began to run unevenly, smoke, lose power or light up the dashboard.

Perhaps it was on White Lion Court, perhaps on the way out towards Colchester, under 15 miles away.

Meaning? Your pump has sucked the AdBlue in.

Distance decides how far it goes: filter and lines to begin with, then the high-pressure pump and every injector.

It travels deeper with each extra mile covered and every restart.

What to do: pull over where it is safe and switch off.

On the M11, under 50 miles from Hadleigh, that means the next junction, not the services further on.

No test restarts: clearing itself isn't something AdBlue does.

About how far did it go? Say so when you phone.

## Hire, lease or company car with AdBlue in the wrong tank

It's a motor you have had for a week.

The AdBlue filler sits right next to the diesel one, which you did not know, because your own vehicle either has no AdBlue or keeps it somewhere else.

It can happen to anyone, anywhere around Suffolk.

What it means: the same as the scenarios above, depending on whether it's run, with one more step.

Plenty of rental and company contracts need the owner's sign-off before work.

Your move: rental firm or your fleet manager first, us second, since settling it beforehand cuts time.

Stuck near Hadleigh Town Sign or at Manningtree till the firm answers, the vehicle stays switched off the whole time.

## AdBlue in your diesel tank? Not sure, around Hadleigh

"I think so" is often as honest as it gets.

Lighter, the bottle; a trace of ammonia round your filler; a hazy recollection of which cap. Look familiar?

A hurried top-up by the gates of Hadleigh Community Primary School, or a visit to a friend in Cobblers Corner: either fit.

Meaning? Spills around the filler don't touch your motor at all.

Once it is inside the diesel tank, though, it does.

Any AdBlue in the tank would be drawn in by firing up the car, and the start would not settle which it is in any case.

Assume it got in, and don't start the key.

Tell us what you noticed on your phone. A clean tank checked counts as a better outcome than a run one drained.

## Each AdBlue drain in Hadleigh shares these stages

Whatever the situation, a single opening applies.

Filling station, driveway, The George's car park or a road by Hadleigh Library — the van reaches the vehicle, and three questions follow: what liquid, what amount, and whether it has run.

Replies set the job; the quote follows on the call while nobody has left yet.

AdBlue forms crystals and eats at certain metals in fuel systems, and so it does not rinse out unaided; that's why a full flush, after the drain, matters far more here than with petrol.

Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested.

Where your motor hasn't been started, expect about half an hour once we arrive, in most cases.

Finally, our technicians fire it up.

With clean diesel in, it runs while we check it's running properly, and then we head off.

When it's noticed quickly, the vehicle very rarely has long-term damage, and the entire job takes place where it is.

Paying is that day, never in advance. For the insurer, you get a VAT invoice and a report from the engineer.

Dig out your insurance before we're en route: misfuelling cover comes included in many policies.

If you're somewhere hard to explain, near Royal British Legion or close to a border, ring and ask instead of guessing.
