# What Now? AdBlue in the Diesel Tank in Slade End

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

Anywhere the car is — Shillingford, Slade End — never start a motor that has not run yet.

Leave your motor and the ignition off then call 0333 366 0103; it's usually a drain and a thorough flush, done where your car is in Slade End.

When the engine has been run, stop somewhere safe straight away, then switch the car off.

It is a bigger job, yet step one does not change.

Compare what happened to a situation from the ones below, wherever around Oxfordshire you are.

## On a Slade End forecourt with AdBlue in a diesel

The cap you unscrewed was the wrong one — and you only notice it as you're standing at the petrol pump, bottle or the nozzle in your hand.

Maybe you're at the Esso, possibly at the BP, maybe somewhere else around Slade End.

The upshot: of every spot to notice, the forecourt is the best.

Only the tank holds AdBlue; not one component beyond it has taken any in.

Next: resist the urge to fire it up only to move away from the petrol pump.

Phone us from the forecourt after the vehicle sits in a bay — the staff will lend a hand to roll it — and save the bottle.

Stuck beside the pump? Explosion-proof kit makes a busy forecourt safe, and so it can be drained where it is.

## Slade End, at home: AdBlue in your diesel tank

On your dash, a reminder had been lit all week.

Only by the recycling, the empty container in hand, did you look back at the cap you'd used on the driveway.

Drives close to Sotwell Street get it as much as anywhere.

Put simply: if your car hasn't been driven since, it's nearly as good as finding out at the pump.

Diesel and AdBlue stay separate: the AdBlue settles to the floor of that tank and stays put, no matter how long it waits.

What to do: leave the keys inside the house so no one moves the car in the morning. Then call.

Out in Mackney or right here in Slade End, the draining is done at your driveway.

Our pumping kit runs quiet enough that it won't wake the neighbours at night.

## AdBlue in a diesel and already driving around Slade End?

A short way beyond topping up, your motor began misbehaving: roughness, smoke, lost power, lights on the dash.

Maybe heading to Oxford, under 15 miles away, or just down A4130.

The point: your system has pulled AdBlue through by now.

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

Each mile and each restart takes it further.

Your move: pull up somewhere sensible, then turn the engine off.

On the M40, under 10 miles from Slade End, that means the next exit, not the services further on.

No test restarts: clearing itself is not something AdBlue will do.

Let us know the distance covered as you call.

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

You've had this vehicle barely a week.

The AdBlue filler is right beside the diesel one, which you didn't know, since your own motor either has no AdBlue or keeps it somewhere else.

Wherever you are around Oxfordshire, any motorist can slip up.

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

Many hire and company agreements want the owner to approve work on your car.

Next: ring the hire company or your fleet manager first, and then us — settling it before our arrival is quicker.

Stuck near St James or at Cholsey until the firm answers, the car remains turned off the whole time.

## Not sure it was AdBlue in the diesel tank, Slade End?

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

A faint ammonia-like whiff lingers near your filler, the bottle seems too light, and the cap you took off is a blur.

A hurried top-up by the gates of Brightwell-Cum-Sotwell Church of England Primary School, or a call to a friend in Preston Crowmarsh: both fits.

Meaning? Drips around the inlet never reach the engine at all.

A diesel tank with AdBlue inside is another story.

If there is AdBlue in that tank, firing up the vehicle would suck it in, and it would not tell you which either.

Do this: behave as though it did, and don't start your engine.

Tell us what you noticed on your phone. A clear tank checked is a happier result than a run one drained.

## What every AdBlue drain around Slade End has in common

Each situation has the same start to the work.

Anywhere your car is — The Red Lion's car park, a road by Lime Walk Gospel Hall, a drive, a filling station — the van arrives and we ask for the fluid, the amount, plus whether the motor has been run.

On the phone, ahead of dispatch, you are told our quote, and those answers shape the work too.

A thorough flush comes after this drain. With petrol it's routine; with AdBlue it is crucial, because crystals form and certain metals corrode, and neither rinses away unaided.

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

Where your motor has not run, expect about half an hour on site, for most jobs.

Our technicians fire it up at the end.

Before our technicians leave, it is tested to be sure it runs smoothly on clean diesel.

Lasting damage is very rare if it's caught soon, and the entire job is done where your car is.

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

Many policies include misfuelling, so check yours as we head over.
