# What Now? AdBlue in the Diesel Tank in Combe St Nicholas

Has the motor run since the AdBlue got in? That single question settles almost everything else from here.

If it has not, keep it that way, whether the vehicle is in Combe St Nicholas itself or out in Chardleigh Green.

Leave the motor and your ignition off and ring 0333 366 0103; it's normally a drain and a thorough flush, done where the car is in Combe St Nicholas.

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 meet, anywhere across Somerset. Pick yours.

## At the pump in Combe St Nicholas: AdBlue in a diesel

Just now, nozzle still in hand, you realise that the cap you took off was the wrong one, there at the petrol pump.

Anywhere in Combe St Nicholas, then — Texaco, Tesco, or anywhere else nearby.

Meaning? Finding out here is the best it gets.

Still in your tank, and no fuel drawn onwards: that's where the AdBlue sits.

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

Get the attendants to lend a hand rolling it into a bay, hold on to the bottle, then phone us from there.

The equipment is explosion-proof and fine on a live forecourt, so a vehicle that can't be pushed away is cleared where it is at the pump.

## At home in Combe St Nicholas with AdBlue in your diesel tank

Days had gone by with the warning light on.

A bottle bought at the shop, tipped in on the driveway — and it's only by the recycling that the cap caught your eye.

Just off New Road is no different from any other place.

Meaning? Provided the vehicle has not been driven since, it's close to the forecourt case.

AdBlue doesn't mix with diesel; it sinks to the bottom of your tank and waits there. Overnight does not change that.

Your move: keys indoors, so no one drives the vehicle anywhere at breakfast. After that, phone.

In Cat Tail or right here in Combe St Nicholas, the draining is done at your drive.

Our equipment runs quietly enough that it won't wake the neighbours at night.

## AdBlue in a diesel and already driving in Combe St Nicholas?

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.

Maybe heading for Exeter, under 50 miles away, or just along Rectory Gardens.

Meaning? Your fuel pump has taken the AdBlue in.

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

More miles, more restarts: deeper it goes.

Pull in safely — that's the first job — then turn it off.

Exit at the first junction — not the services further along — if you are on the M5, under 10 miles from Combe St Nicholas.

Restarting it to check achieves nothing — AdBlue never clears itself.

Phone, and say what distance the vehicle was driven.

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

A week back, it was new to you.

Unknown to you, the AdBlue and diesel fillers are next to each other here — unlike your own vehicle, which has none or stores it in another spot.

Any driver, wherever across Somerset, could make it.

The upshot: just as above, divided by whether it ran, but with an added step.

Any work on the car frequently needs the owner's go-ahead under rental or company agreements.

What to do: call the hire firm or your fleet manager first, then us. That is faster settled before we get there than after.

If you're stuck in the car park at Axminster, or by St Nicholas, while you wait for an answer, leave your car off.

## AdBlue in your diesel tank? Not sure, around Combe St Nicholas

Honestly, the only answer may be that you think it did.

A slight ammonia-like whiff lingers near your filler, the bottle seems too light, and which cap came off is a blur.

Maybe at a friend's drive in Willhayne, or in a rush by Combe St Nicholas Church of England VA Primary School at the school run.

The point: your engine is not hurt by some AdBlue splashed on the outside.

In the diesel tank, by contrast, AdBlue damages it.

If there is AdBlue in the tank, turning on the vehicle would suck it in, and it would not tell you which either.

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

Tell us what you noticed on the phone. A clear tank checked counts as a happier outcome than an already-run one emptied.

## The common ground in every Combe St Nicholas AdBlue drain

The job opens the same way, whatever the situation.

Anywhere the vehicle is — The Green Dragon's car park, a street by Combe St Nicholas Methodist Church, a driveway, a filling station — our van gets there and we ask about the fluid, the amount, plus if your motor has been run.

The price comes on the call, ahead of anyone setting off, and the replies set the work.

Then that tank is emptied and the system rinsed thoroughly, which matters 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; fresh diesel goes in; and the vehicle is tested.

Most unstarted vehicles are a half-hour job after the moment our technicians get there.

Firing it up comes at the end.

With clean diesel in, it runs while we check it's running correctly, and then we head off.

Long-term damage is very uncommon when it is caught soon, and the entire job is done where your car is.

You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer.

Worth knowing: many insurers offer misfuelling cover, and so a quick look at your policy as we travel is worthwhile.
