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

One fact counts most when AdBlue is in a diesel tank, and that is whether your engine has run since.

Out in Ardnadam or right around Dunoon, an unrun engine must stay unrun.

Usually that is draining and properly flushing it right there around Dunoon — so leave the key and engine off then phone 0333 366 0103.

Already run? Stop when safe, then switch it off.

It's a larger job, though stage one does not change.

Find the scenario below that matches yours, wherever in Argyll and Bute it happened.

## Dunoon forecourt: AdBlue in a diesel at the pump

The cap you unscrewed was the wrong one — and you just notice it as you are stood at the pump, bottle or nozzle in your hand.

Somewhere around Dunoon, then — Shell, another forecourt nearby, or somewhere else nearby.

Meaning? Spotting it on the forecourt is as good as it can be.

No pump has pulled it in, so the AdBlue sits only in that tank.

What to do: do not get back in and crank it to clear the petrol pump.

Ask the attendants to help you roll your car into a parking space, keep the till receipt or the bottle, then phone us from the forecourt.

The equipment is explosion-proof and safe on a live forecourt, and so a car that cannot be pushed away gets drained where it is at the pump.

## At home around Dunoon with AdBlue in your diesel tank

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

Picked up a bottle, tipped it in outside the house, recycled the empty — and at that point looked at the cap again, after the fact.

Houses just off McArthur Street are hit as often as everywhere else.

Put simply: if your car hasn't been driven since, it's nearly equal to finding out at the forecourt.

Diesel and AdBlue stay separate: the AdBlue drops to the floor of the tank and stays there, no matter how long the night.

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

Our technicians drain it on your drive, whether that is in Dunoon or out in Kirn.

Late-night clears beside a house are no problem: the pumps are quiet.

## Dunoon: set off with AdBlue in a diesel?

Topped up, pulled away, and soon the engine was turning unevenly, smoking, losing power, or flashing up the dash.

Anywhere along Argyll Street or on the road to Glasgow — under 50 miles away.

Meaning? The pump has taken the AdBlue up.

Distance decides how far it gets: filter and lines to begin with, then the injection pump and each injector.

Every restart, like every mile, carries it deeper.

Next: find a sensible spot, pull in, and turn your motor off.

Service stations farther along can wait: on the M8, under 15 miles out of Dunoon, use the next junction.

Do not restart it to see if it has cleared; it will not have.

Tell us hear the mileage covered as you call.

## Hire, lease or company car with AdBlue in the wrong tank

It's a vehicle you have had for a week.

The AdBlue filler sits right next to the diesel filler, which you did not know, since your own motor either has no AdBlue or keeps it somewhere else.

It can happen to anyone, anywhere in Argyll and Bute.

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

Work on the vehicle often requires the owner's approval under rental or fleet agreements.

Sorting it before we turn up is quicker, and so phone the rental company or your fleet manager, then us.

Leave the vehicle switched off while the answer comes, even if you're parked outside Inverkip or close to Studio Cinema Dunoon.

## Unsure about AdBlue in your diesel tank in Dunoon?

Truthfully, the best answer might be that you think it did.

The bottle is lighter than it should be, there is a faint smell of ammonia round the filler, and you cannot remember which cap you took off.

It might have been at a friend's driveway in Sandbank, or rushing by the local primary school at the school run.

In short: a spill near your filler does your engine unharmed.

The diesel tank with AdBlue in it is a different matter.

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

Next: act as though it got in, and leave your engine off.

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.

## What every AdBlue drain in Dunoon has in common

The work begins identically, whatever your case.

Three things are asked once our engineers arrive — at a forecourt, a drive, a street by St John's Church or the car park at The Lorne: the fluid, the amount, and whether it has run.

The price comes over the phone, ahead of anyone setting off, and the answers shape the job.

Draining the tank comes next, then a full flush — more vital with urea than after petrol, since crystals and corrosion won't clear by themselves, no matter how long you wait.

Then comes your filter — flushed, or swapped when needed — followed by clean diesel, and a test of the car.

If your motor has not run, most jobs take about half an hour once we are there.

Lastly, our technicians start the engine.

We confirm it runs smoothly on clean diesel before we leave.

Permanent damage is very uncommon if it's caught soon, and the entire job is done where the vehicle is.

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

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