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

One thing counts most once AdBlue is in a diesel tank, and it is if your engine has been started afterwards.

Not run so far? Then keep the car like that, wherever the car sits — Westlea or Westmead.

Ring 0333 366 0103 with your ignition and engine still off. In Westlea, that is generally emptied and cleaned where it stands.

Stop the minute it is safe and turn off, if it has already run.

A larger job, yes, but the identical first move.

Find the situation below that matches yours, wherever around Wiltshire it happened.

## On a Westlea forecourt with AdBlue in a diesel

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

Perhaps you are at the Asda, maybe at the Shell, possibly somewhere else around Westlea.

Meaning? Finding out on the forecourt is the best it gets.

Only the tank has AdBlue; not one part past it has drawn it in.

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

Ask the staff to help you roll your car into a parking spot, keep the receipt or the bottle, then ring us from the forecourt.

Emptying it right at the petrol pump is fine when it cannot be shifted, since the equipment is explosion-proof.

## AdBlue in the diesel tank on a Westlea drive?

For days the dash had been nagging you.

Picked up a container, poured it in at home, recycled the empty — and only then checked the cap a second time, too late.

It takes place on driveways just off Whitehill Way as commonly as anywhere.

Put simply: if your vehicle has not moved since, it's nearly equal to spotting it at the forecourt.

As it is reluctant to mix, AdBlue drops low in that tank and waits. A night parked alters nothing.

Next: prevent any early drive by putting the keys in the house, then ring us.

In Eastleaze or here in Westlea, the draining happens at your driveway.

The pumps are quiet enough to use outside a house after dark.

## On the road in Westlea with AdBlue in a diesel

Rough running, smoke, lost power or a glowing dashboard arrived a mile or two after the fill.

Somewhere along Langstone Way or on the road to Bath — under 50 miles away.

In short: the AdBlue has been pulled into the system.

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

Each mile and each restart takes it further.

Next: pick a safe spot, pull in, and switch the motor off.

On the M4, under 3 miles from Westlea, that means the next junction, not the services further on.

It will not have cleared, and so there's no sense restarting to check.

About how far had it go? Tell us when you phone.

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

Seven days ago, it was new to you.

Unbeknown to you, the two inlets are side by side here — unlike your own vehicle, which has no AdBlue or keeps it in another spot.

It can happen to anyone, anywhere across Wiltshire.

Put simply: one extra step on top of the situations above, which turn on whether it's run.

Any work on the car often requires the owner's approval under rental or fleet terms.

Next: phone the rental company or the fleet manager first, then us — settling it before our arrival is quicker.

Leave the car off as the reply arrives, whether you are waiting at Swindon or near St. Peter's Catholic Church.

## Westlea: unsure if it was AdBlue in your diesel tank?

Truthfully, the only answer might be that you think so.

Too light, the bottle; a hint of ammonia near the filler; a hazy memory of the cap. Sound familiar?

A hurried top-up by the gates of Westlea Primary School, or a call to a friend in Bridgemead: both fit.

Put simply: a spill round the filler leaves your engine unharmed.

If it is inside your diesel tank, though, it does.

Any AdBlue in the tank would be sucked in by firing up the car, and the start wouldn't settle which it is in any case.

Next: act as though it got in, and keep your motor off.

Ring us and explain what you saw; we would rather check a tank that turns out free of AdBlue than drain one that has already been run.

## The common ground in each Westlea AdBlue drain

Whatever the case, a single start is used.

Forecourt, driveway, The Harvey's car park or a road by West Swindon Shopping Centre — the van comes to your car, and three questions follow: what liquid, what amount, and whether it has run.

Replies set the work; the quote follows on the call while no one has set off yet.

A thorough flush comes after this drain. With petrol it's routine; with AdBlue it's essential, since deposits form and some metals are attacked, and neither washes away unaided.

Clean diesel is put in once the filter has been cleaned or replaced, and your car is finally checked.

Where the motor hasn't been started, allow roughly half an hour once we arrive, for most jobs.

The last step is firing it up.

With new diesel in, it runs while we confirm it is running correctly, and then we head off.

We do the whole job where your car is, and lasting damage is very rare if it has been spotted quickly.

For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, nothing upfront.

Many policies include misfuelling, so check yours while the van travels.

## AdBlue drains about Westlea and across Wiltshire

As a residential suburb, Westlea shares its vans with the surrounding towns — Toothill, Rivermead — right across SN postcodes.

A postcode starting SN5 7 is the quickest way to tell us where you are.

Whether your car is on a lay-by on the way to Shaw Ridge Linear Park or in a car park in the middle of Westlea, it does not need to shift.

The van drains it where it stands.

Awkward to explain? By Cineworld or a border? Checking is better than assuming, and so ring.
