# Dan Caerlan: AdBlue in the Diesel Tank? Find Your Situation

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

Anywhere your car is — Talbot Green, Dan Caerlan — don't run an engine that has not been started yet.

Switch nothing on, ring 0333 366 0103, and count on a thorough flush after a drain, done right where your car sits in Dan Caerlan.

Already run? Stop when you safely can, then switch everything off.

Step one stays unchanged, even though the job is bigger.

Further down: the cases our technicians meet, wherever across Rhondda Cynon Taf. Pick yours.

## Dan Caerlan forecourt: AdBlue in a diesel at the pump

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

Possibly you're at the Tesco, perhaps at the Texaco, maybe somewhere else around Dan Caerlan.

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

The AdBlue is inside the tank and nowhere else. Nothing has sucked it in.

Next: resist the temptation to start it only to move away from the petrol pump.

Ask the staff to help you push the car into a parking bay, keep the receipt or the bottle, and call us from the forecourt.

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

## At home in Dan Caerlan with AdBlue in your diesel tank

Several days had passed with the dash light on.

Only at the recycling bin, the empty container in your hand, did you glance back at the cap you had opened at the driveway.

Drives near B4595 see it as much as anywhere.

The point: no miles since leaves it almost as good to spotting it at the petrol pump.

Being unable to blend, AdBlue settles to the base in that tank and stays. One night standing alters nothing.

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

Our engineers drain it on your driveway, whether that's around Dan Caerlan or out in Brynteg.

The pumps are quiet enough to use outside a house at night.

## AdBlue in a diesel and already driving in Dan Caerlan?

Rough running, smoke, lost power or a glowing dashboard started a mile or two after the top-up.

It might have been heading for Cardiff, under 10 miles away, or just down Newbridge Road.

What it means: the system has pulled the AdBlue in.

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

Each mile and each restart takes it further.

Your move: pull up anywhere sensible, then switch the engine off.

On the M4, under 3 miles from Dan Caerlan, that means the next exit, not the services further on.

Don't restart the vehicle to see if it has cleared; it will not have.

Call us and say how far you travelled.

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

You've had this vehicle hardly a week.

The AdBlue filler is right beside the diesel one, which you didn't know, since your own vehicle either has no AdBlue or keeps it somewhere else.

It can happen to anyone, anywhere in Rhondda Cynon Taf.

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

Plenty of rental and fleet agreements need the owner's sign-off for work.

Your move: rental firm or fleet manager first, us next, since sorting it early cuts time.

Hanging on for a reply in the car park at Pontyclun, or beside Caerlan Community Hall and The Parish Office? Leave your engine off throughout.

## AdBlue in your diesel tank? Not sure, around Dan Caerlan

Sometimes the fair answer is "I think so".

Too light, the bottle; a hint of ammonia round your filler; a hazy memory of the cap. Look familiar?

The gates of the local primary school in a rush, perhaps, or a friend's driveway over in Beddau.

The point: your engine is not harmed by a little AdBlue splashed on the filler.

Once it's inside your diesel tank, though, that changes.

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

What to do: treat it as if it went in. Don't fire it up.

Call 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 Dan Caerlan has in common

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

Filling station, driveway, Llantrisant RFC's car park or a road by Tabor Baptist Church — the van reaches your vehicle, and three questions follow: which liquid, what quantity, and whether it has run.

Answers set the job; the quote follows by phone whilst nobody has set off yet.

A thorough flush comes after this drain. With petrol it's standard; with AdBlue it's essential, since crystals build up and certain metals corrode, and none of that rinses out unaided.

Then comes your filter — cleaned, or replaced where necessary — then clean diesel, and a test of the vehicle.

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

Firing it up comes at the end.

Our test that it runs correctly on fresh diesel comes before we leave.

Our technicians do the whole job where the vehicle is, and long-term damage is very unusual if it has been caught soon.

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

Dig out your insurance while we're en route: misfuelling cover comes built into plenty of policies.
