# AdBlue in the Diesel Tank in New Eltham: What Now?

One fact counts most once AdBlue is in a diesel tank, and that is if the motor has been started since.

Not run yet? Then leave it that way, whether the car is — New Eltham or Avery Hill.

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

Where the engine has run, pull in somewhere safe first, then turn the vehicle off.

The job is bigger, but the first stage is the same.

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

## New Eltham forecourt: AdBlue in a diesel at the pump

Imagine it: stood by the petrol pump, gripping the nozzle, you realise the filler you opened wasn't the right one.

Somewhere in New Eltham, then — Shell, Sainsbury's, or somewhere else nearby.

The upshot: of all places to notice, this is the best.

The AdBlue is in the tank and nowhere else. Nothing has sucked it in.

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

Have the staff to lend a hand rolling it into a bay, save the receipt, then ring us right there.

Stuck by the pump? Our explosion-proof equipment keeps a live forecourt sensible, so we can drain the vehicle in place.

## At home in New Eltham with AdBlue in the diesel tank

Days had gone by with the dash light on.

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

Right off Parkview Road is not different from anywhere.

Put simply: if the vehicle hasn't been driven since, it is almost as good as spotting it at the pump.

As it is reluctant to mix, AdBlue settles low inside your tank and stays. A night standing alters nothing.

What to do: leave the keys inside the house so nobody moves the car in the morning. Then ring.

Eltham or New Eltham: wherever your driveway sits, that is where it is cleared.

Night-time drains outside a house are fine: the pumps are low-noise.

## New Eltham: drove off with AdBlue in a diesel?

A mile or two after topping up, your engine started misbehaving: rough running, smoke, lost power, lights on your dash.

Perhaps it was on Broad Lawn, maybe on the way out towards London, under 10 miles away.

Put simply: the AdBlue has been pulled through the system.

It has been through the fuel filter and your lines and, the further you went, into your high-pressure pump and the injectors.

More driving, more restarts: deeper it goes.

Stop safely — that is the first step — then switch it off.

Service stations farther along are too far: from the M20, under 10 miles out of New Eltham, use the first junction.

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

Ring us and say how far you went.

## A hire or company car with AdBlue in the wrong tank?

Seven days ago, the car was new to you.

On your own vehicle, AdBlue is missing or elsewhere. On this one, its inlet is right next to the diesel inlet — a surprise to you.

It can happen to anyone, anywhere across Greater London.

The upshot: exactly as above, split by whether it ran, only with an added step.

The owner frequently needs to sign off the work, under plenty of rental and fleet agreements.

Next: ring the rental company or the fleet manager first, and then us — sorting it before we arrive is quicker.

Stuck near STC Sports Club or outside the nearest station till someone answers, your car stays turned off throughout.

## Unsure about AdBlue in your diesel tank around New Eltham?

"I think so" is sometimes as honest answer there is.

What cap was taken off, you cannot recall; meanwhile the bottle feels lighter than expected, and a whiff of ammonia lingers by your filler.

Possibly it happened in a hurry at the school gates at Wyborne Primary School, or on a friend's drive in Foxbury.

The upshot: the engine is not harmed by some AdBlue splashed around the outside.

AdBlue inside the diesel tank does.

If there is AdBlue in your tank, turning on the car will pull it in, and it wouldn't tell you which either.

Your move: behave as if it got in, and don't start your motor.

Ring and give what you saw: we would rather find a tank free of AdBlue than drain one after the engine has run.

## What each AdBlue drain around New Eltham has in common

Whatever the case, a single opening is used.

Our engineers come to your car, whether it is on a forecourt, a drive, the car park outside The Beehive or a side street close to New Eltham Library, and ask three things: what got in, roughly how much, and if your motor has been run.

On the phone, before dispatch, you are told our quote, and those replies decide the work too.

Then the tank is cleared and the system purged thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't rinse out on its own.

Last come the filter, cleaned or renewed as needed; fresh diesel; and a check of your vehicle.

Where the engine hasn't run, expect about half an hour once we arrive, in most cases.

Firing it up comes at the end.

With fresh diesel in, it runs while our engineers confirm it is running properly, and then we go.

Permanent damage is very unusual when it's noticed quickly, and the whole job is done where the car is.

For your insurer: an engineer's report and the VAT invoice. For you: payment that day, nothing in advance.

It is worth knowing: many insurers offer misfuelling cover, so a quick look at your policy while we travel pays.
