# AdBlue in the Diesel Tank in Tomperrow: What Now?

Everything turns on a single detail: if the motor has been run after the AdBlue was added — more than anything else.

Wherever your car stands — Baldhu, Tomperrow — never run a motor that hasn't run yet.

Leave your engine and the ignition off and call 0333 366 0103; it is generally a drain and a thorough flush, done where the vehicle is around Tomperrow.

If it's run, stop as soon as it is safe then switch off.

It's a bigger job, though step one doesn't change.

Below: the cases our technicians see, anywhere across Cornwall. Pick the one that fits.

## On a Tomperrow forecourt with AdBlue in a diesel

Only at this point, nozzle yet in hand, it dawns on you that the cap you took off was the wrong one, right at the pump.

Somewhere in Tomperrow, then — Esso, Sainsbury's, or somewhere else nearby.

Meaning? Spotting it on the forecourt is as good as it gets.

Still inside your tank, and nothing pulled through: that's where the AdBlue is.

Your move: keep out of the driver's seat, even if the queue wants freeing.

Ask the staff to help you push the vehicle into a parking spot, keep the receipt or the bottle, then phone us from the forecourt.

If it cannot be moved, it can be cleared at the petrol pump: the equipment is explosion-proof and fine on a working forecourt.

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

For days the dash had been warning you.

A bottle bought at the garage, emptied in on the driveway — and it's just by the bin that the cap caught a second look.

It takes place on driveways just off Truro Business Park as commonly as anywhere.

In short: if the vehicle has not moved since, it is almost equal to finding out at the pump.

Being unable to mix, AdBlue drops low in that tank and waits. One night parked changes nothing.

Next: the keys in the house, and so nobody takes the car off at breakfast. After that, phone.

Your drive is where it gets drained, whether around Tomperrow or Threemilestone.

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

## AdBlue in a diesel and already driving around Tomperrow?

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

Perhaps it was on Glenthorne Court, maybe on the way out towards Truro, under 5 miles away.

Put simply: the AdBlue has been sucked into your fuel system.

Through your filter, along the lines, and — the more the distance — deeper into the injection pump and every injector.

More driving, more starts: further it travels.

What to do: pull over where it's safe to do so then switch off.

Services farther on can wait: from the M5, over 50 miles out of Tomperrow, take the next junction.

No test restarts: clearing is not something AdBlue does.

Call, saying what distance your car was driven.

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

Seven days ago, it was unknown to you.

Your own motor either does without AdBlue or puts it elsewhere, so no one told you the AdBlue inlet sits right beside your diesel.

Across Cornwall, nobody is safe from it.

Meaning? Whichever applies above counts here — run or unrun — plus one further step.

Many rental and company contracts need the owner's sign-off before work.

Your move: hire firm or fleet manager first, us second, because sorting it early saves time.

Leave the car switched off while the answer arrives, whether you are waiting at Truro or close to Threemilestone Methodist Church.

## Unsure about AdBlue in the diesel tank in Tomperrow?

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

Which cap came off, you cannot say; but the bottle feels less than expected, and a whiff of ammonia hangs by the filler.

It might have been at a friend's drive in Saveock, or in a rush by Threemilestone School on the school run.

The upshot: the motor is not hurt by some AdBlue splashed around the filler.

The diesel tank with AdBlue inside is another matter.

Firing up your car cannot tell you which, and if there is AdBlue in your tank it would pull it in.

Your move: act as though it got in, and don't start your engine.

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

## Every AdBlue drain in Tomperrow shares these steps

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

Wherever your car stands — Victoria Inn's car park, a road by Threemilestone Community Centre, a drive, a forecourt — our van gets there and we ask about the fluid, the quantity, and if the engine has been run.

Those replies decide the work, and you hear our quote on the phone, before anybody sets off.

Draining your tank comes next, then a full flush — more important after urea than after petrol, since crystals and corrosion will not go by themselves, however long you wait.

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

The majority of unrun cars are a half-hour job from the moment our technicians turn up.

Lastly, we start the car.

Our technicians check it runs properly on new diesel before we go.

Our engineers do the whole job where the vehicle is, and lasting damage is very unusual when it has been noticed early.

Paying is that day, never in advance. For your insurer, there is a VAT invoice plus a report from the engineer.

It is worth knowing: lots of insurers include misfuelling cover, and so a check of your policy while you wait pays.

The drain happens on the spot.

Guessing won't help beside Truro Sports Hub, on a county line or somewhere hard to describe; phone and check.
