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

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

Out in Tolcarne or right around Tolgullow, an unstarted motor should remain that way.

Call 0333 366 0103 with the key and motor both off. Across Tolgullow, that is typically drained and flushed on the spot.

Already run? Pull over when safe, then switch everything off.

A bigger job, then, yet the same opening step.

Match what happened to a situation from the list below, wherever across Cornwall you are.

## At the pump in Tolgullow: AdBlue in a diesel

Just at this point, bottle still in hand, you realise that the cap you took off was the wrong one, there at the pump.

It might be the Texaco, or the Opie Oils, or a different station around Tolgullow.

Meaning? Spotting it on the forecourt is the best it gets.

No pump has pulled it through, and so the AdBlue sits just inside your tank.

Clearing the petrol pump is no excuse to start it — so don't get back in.

Phone us from the forecourt after the car is in a bay — the staff will help roll it — and save the receipt.

Stuck by the petrol pump? Our explosion-proof kit makes a busy forecourt sensible, so it can be drained where it is.

## AdBlue in your diesel tank on a Tolgullow drive?

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

A bottle bought at the garage, emptied in on the driveway — and it was just at the recycling that the cap caught a second look.

Driveways close to B3298 see it as much as any other street.

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

Diesel and AdBlue stay separate: the AdBlue settles to the floor of your tank and remains there, however long the night.

Next: the keys in the house, so nobody drives your vehicle anywhere first thing. After that, phone.

Your driveway is where it is drained, whether around Tolgullow or St Day.

Night-time drains outside a house are no problem: the pumps are low-noise.

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

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

Wheal Gorland Road, perhaps, or the route towards Truro — a run of under 10 miles.

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

Mileage sets how far it gets: filter and pipework first, then the high-pressure pump and each injector.

Every restart, like each mile, carries it deeper.

Stop somewhere safe — that's the first step — then turn it off.

Services further along can wait: from the M5, over 50 miles out of Tolgullow, take the next junction.

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

Let us know the mileage driven as you call.

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

A week ago, it was unknown to you.

Unbeknown to you, the AdBlue and diesel fillers are next to each other here — unlike your own vehicle, which has no AdBlue or stores it elsewhere.

Anywhere you happen to be in Cornwall, every motorist could slip up.

The point: just as above, divided by whether it ran, only with an added stage.

Plenty of hire and company agreements want the owner to approve work on the car.

What to do: call the hire firm or your fleet manager first, then us. That's quicker settled before our technicians turn up than after.

Waiting for a reply in the car park outside Redruth, or near St Day Methodist Church? Keep the car off throughout.

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

Now and then, "I think so" is the most anyone can honestly say.

What cap was taken off, you cannot say; but the bottle weighs less than it ought to, and ammonia lingers by the filler.

The gates of St Day and Carharrack Community School in a hurry, say, or a friend's driveway out in Crofthandy.

Meaning? Spills outside the inlet don't touch the motor at all.

A diesel tank with AdBlue in it is another story.

You can't tell which by turning the ignition, and doing so will suck in any AdBlue that is in the tank.

What to do: treat it as if it was put in. Do not start the vehicle.

Inspecting a tank that proves clean beats draining one after it has been run — so phone and describe to us what you saw.

## What each AdBlue drain in Tolgullow has in common

Each situation has the same start to the work.

Wherever your vehicle stands — St Day Inn's car park, a street beside Mills Court Community Centre, a drive, a filling station — our van arrives and asks for the liquid, the quantity, plus if your motor has turned over.

Over the phone, ahead of anything else, you are told our quote, and those answers decide the work too.

A thorough flush comes after this drain. With petrol it's standard; with AdBlue it is essential, because crystals build up and certain metals are attacked, and neither rinses out unaided.

Finally are the fuel filter, flushed or replaced as needed; fresh diesel; and a test of your car.

Never started? Then roughly half an hour once we are there is most jobs.

Firing it up comes last.

With clean diesel in, it runs while our technicians check it is running smoothly, and then we head off.

The whole job is done where your car is, and if it is noticed soon, long-term damage is very rare.

Paying is on the day, never upfront. For your insurer, you get a VAT invoice plus a report from the engineer.

Plenty of policies include misfuelling, and so look at yours as we head over.

## AdBlue drains across Cornwall, Tolgullow included

Tolgullow is a residential suburb, and the same vans that cover it work the places around it too, Vogue and Little Beside among them, across the TR postcode area.

Giving us a TR16 5 postcode pins you quickest of all.

No towing is needed, whether parked centrally in Tolgullow or on a lay-by heading to Unity Wood, and so keep it where it is.

Our van drains it in place.

Guessing doesn't help near St Day Community Centre, close to a border or anywhere awkward to describe; phone and ask.

## In one line: your scenario

Motor never started: ring, and leave it alone.

Already run: stop, switch off then call. Either way, Petrol in Diesel takes it from there in Tolgullow and anywhere in Cornwall on 0333 366 0103.
