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

One fact matters above all when AdBlue is in a diesel tank, and it is if the engine has been started afterwards.

Over in East Sheen or right around Barnes, an unrun motor should stay that way.

Leave the engine and the ignition off then call 0333 366 0103; it's usually a drain and a thorough flush, done where your car is around Barnes.

Already run? Stop once safe, then switch everything off.

A larger job, then, but the identical opening move.

Anywhere around Greater London it happened, one of the cases below matches yours.

## On a Barnes forecourt with AdBlue in a diesel

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.

Be it Esso, BP or somewhere else around Barnes, the situation is identical.

The upshot: of every spot to find out, this is the best.

Nothing has drawn it through, so the AdBlue sits just in that tank.

What to do: don't get back in and start the car to clear the pump.

Three jobs: a push into a space with the staff helping, the bottle kept, and a call to us from where you stand.

If it can't be shifted, it can be emptied at the pump: the equipment is explosion-proof and safe on a working forecourt.

## AdBlue in your diesel tank at home around Barnes

On your dash, a warning had been lit for days.

Only by the recycling, the empty bottle in hand, did you look back at the cap you had opened at the driveway.

It occurs on driveways just off St. Anns Road as regularly as anywhere.

What it means: if you have not driven since, this is nearly as good as the forecourt.

Diesel and AdBlue keep apart: the AdBlue settles to the base of the tank and stays there, no matter how long the night.

Your move: the keys indoors, so no one takes the car anywhere at breakfast. After that, ring.

Mortlake or Barnes: whichever your drive sits, that's where it gets drained.

Night-time clears beside a house are fine: the pumps are low-noise.

## Set off with AdBlue in a diesel in Barnes?

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

Somewhere on Melrose Road or else on the road to Westminster — under 10 miles away.

What it means: your fuel system has drawn the AdBlue in.

Past the fuel filter, along the pipework, and — the further the distance — on into the high-pressure pump and each injector.

Each restart, like each mile, pushes it deeper.

Next: find a sensible spot, pull in, and switch your motor off.

Services further on can wait: from the M4, under 3 miles out of Barnes, use the first junction.

Starting it again to check achieves nothing — AdBlue doesn't clear on its own.

About how far did it go? Tell us as you phone.

## AdBlue in the wrong tank of a hire, lease or company car

You have just had the car for days.

Unbeknown to you, the two fillers sit side by side here — unlike your own car, which has none or stores it in another spot.

It can happen to anyone, anywhere in Greater London.

Meaning? Whatever case above counts here — run or not — plus one extra stage.

Plenty of hire and company contracts want the owner to approve work on the vehicle.

Do this: hire firm or your fleet manager first, us second, since settling it early saves time.

If you're stranded in the car park outside Barnes Bridge, or by Barnes Community Association, whilst you wait for an answer, leave the car off.

## AdBlue in the diesel tank? Not sure, around Barnes

At times the fair answer is "I think so".

What cap was taken off, you can't say; but the bottle feels less than it ought to, and ammonia lingers by your filler.

A hurried top-up by the gates of St Osmund's Catholic Primary School, or a call to a friend in Gunnersbury: either fits.

The upshot: the motor is not harmed by some AdBlue spilled around the filler.

Once it is inside the diesel tank, though, that changes.

You cannot tell which by turning the ignition, and doing so will pull in any AdBlue that is in that tank.

Next: assume it got in, and leave your motor off.

Call us and describe what you saw; we would rather check a tank that turns out clean than drain one that has already been run.

## Barnes: what each AdBlue drain has in common

Whichever scenario you are in, the job starts the same way.

Wherever the car is — Coach and Horses's car park, a street beside Henry Fielding, a driveway, a forecourt — our van arrives and we ask about the fluid, the amount, plus if your engine has been run.

Those replies settle the work, and you hear the quote on the phone, before anybody heads out.

Emptying the tank comes next, followed by a careful flush — more important after urea than with petrol, because crystals and corrosion will not clear on their own, no matter how long it sits.

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

If the engine hasn't run, the majority of jobs take about half an hour once we're there.

Starting the engine comes at the end.

Our test that it runs properly on new diesel comes before our engineers go.

If it's spotted soon, the vehicle very seldom has lasting damage, and the whole job happens where it is.

You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer.

Many insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
