# What Now? AdBlue in the Diesel Tank in Upper Up

All of that hinges on a single fact: if the engine has been run since the AdBlue went in — more than anything else.

Not started so far? Then keep the car that way, wherever your car sits — Upper Up or Shorncote.

Normally that is emptying and properly purging it on the spot in Upper Up — so keep your ignition and motor off and call 0333 366 0103.

Where the motor has been run, pull in safely straight away, then turn the vehicle off.

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

Compare your case to one of the ones below, anywhere around Gloucestershire you happen to be.

## At the petrol pump in Upper Up: AdBlue in a diesel

You're at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one.

Anywhere in Upper Up, then — Tesco, Esso, or somewhere else close by.

What it means: this is the best place to find out.

Still in the tank, with nothing pulled onwards: that is where the AdBlue sits.

Next: avoid the urge to start it only to move away from the petrol pump.

Ask the attendants to help you roll the vehicle into a parking bay, keep the till receipt or the bottle, then call us from the forecourt.

Draining it right at the petrol pump is fine when it can't be shifted, because the equipment is explosion-proof.

## At home around Upper Up with AdBlue in the diesel tank

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

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

It happens on driveways just off Neigh Bridge Close as commonly as anywhere.

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

As it is unable to blend, AdBlue drops to the base in the tank and waits. A night standing changes nothing.

Next: keys indoors, and so nobody takes your vehicle anywhere first thing. After that, ring.

In South Cerney or right here around Upper Up, the draining happens on your driveway.

Our pumping kit works quiet enough that it won't wake the street at night.

## On the road around Upper Up with AdBlue in a diesel

A mile or two beyond filling up, your engine started misbehaving: roughness, smoke, lost power, warnings on your dash.

Waters View, perhaps, or the way to Gloucester — a run of under 25 miles.

The upshot: your system has drawn AdBlue through already.

Distance decides how deep it goes: filter and pipework first, then the high-pressure pump and every injector.

It goes deeper with every mile driven and each restart.

Next: pick a sensible spot, stop, then switch your engine off.

Exit at the first junction — not the services beyond — if you are on the M4, under 10 miles from Upper Up.

Restarting it to test achieves nothing — AdBlue doesn't clear on its own.

Phone us and say how far you travelled.

## AdBlue in the wrong tank: hire, lease and company vehicles

A week ago, it was new to you.

Your own car either does without AdBlue or keeps it somewhere different, and so nothing warned you the AdBlue inlet was just next to your diesel.

Wherever you happen to be in Gloucestershire, every motorist can slip up.

In short: an extra stage on top of the cases above, and those turn on whether it's run.

Work on the vehicle often requires the owner's approval under hire or fleet terms.

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

Keep it off as the reply arrives, whether you're parked at Kemble or near South Cerney Cross.

## AdBlue in the diesel tank? Not sure, in Upper Up

Sometimes the fair answer is "I think so".

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

It might have been at a friend's drive in Ashton Keynes, or in a rush outside Ann Edwards Church of England Primary School on the school run.

What it means: a little spilled around the filler does no harm to your motor.

If it's inside the diesel tank, though, that changes.

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

Take it that it was put in, and don't turn your engine.

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.

## The common ground in each Upper Up AdBlue drain

Whatever the case, a single start is used.

Our technicians come to the car, whether it is at a forecourt, a driveway, the car park outside Eliot Arms or a side street near All Hallows Parish Church, and ask three things: what was put in, about how much, and whether your motor has been run.

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

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

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

Where your motor hasn't run, allow about half an hour on site, in most jobs.

The final step is firing it up.

We make sure it runs correctly on fresh diesel before leaving.

When it's noticed early, the car very rarely has lasting damage, and the entire job happens where it is.

For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, no money in advance.

Worth remembering: many insurers include misfuelling cover, and so a quick look at your documents as we travel pays.
