# AdBlue in a Diesel Tank in Nork? Don't Start It

With AdBlue in your diesel tank, the ignition stays off and so does your motor.

AdBlue is urea dissolved in water.

The harm starts once it's sucked through your lines — it will not burn, and it won't combine with diesel.

Caught before your engine has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is in Nork.

Before you do anything else, phone 0333 366 0103.

## Nork, AdBlue in your diesel tank: what to do straight away

Things to do:

- So no one can turn your ignition on, take the keys out.

- Close to moving traffic? Then put the hazard lights on.

- So you can tell us which fluid it was and about how much, save the receipt or the empty bottle.

- Give us a postcode starting SM7 1, or whatever street is nearest, and the van finds you straight — so ring wherever you are.

Not to do:

- Not even for a second, and not to roll the car: the motor stays off.

- Turning the key to ignition alone starts your pump running on many diesels. Skip it.

- Don't top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.

- Any driving at all is to be avoided, even a short distance up Fir Tree Road.

- Draining the tank on your own by the road isn't worth trying.

Get the attendants to help you roll your car away from the pumps if you're at a forecourt in Nork, whether it's the BP or somewhere else.

On that drive, the car stays just as it was left.

## AdBlue in a diesel tank: what it does

Not the engine but your exhaust is where AdBlue is meant to go.

It goes into its own tank and is sprayed into the exhaust gas to clean it.

A fuel pump is not made to cope with it, and AdBlue was never supposed to travel through one.

Inside a diesel tank it behaves very differently from fuel. It does not mix in.

It drops, since it's heavier than diesel, and pools down where the intake draws its supply from.

Once your system runs, the AdBlue is first to go through. Before then it waits underneath the diesel, and that is why a vehicle filled in Banstead yesterday and never started stays the straightforward case, as long as nobody touches the key.

Two kinds of damage come from there.

Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filters and narrow passages; meanwhile, because it attacks certain metals, each part it reaches suffers for as long as it stays inside.

Pipes holding AdBlue spell damage by morning for a vehicle parked in Nork. Only in that tank, it stays stable.

Then there is the water: it offers no protection to the parts that need it the most — the injection pump and every injector.

## Why is AdBlue in a diesel frequently the bigger problem?

Fill a diesel with petrol by mistake over at the Texaco, and the problem is thinned fuel.

It mixes with your diesel, and whilst it is in the tank it causes no damage; the harm comes from running your engine on it.

AdBlue in a diesel is a problem of the wrong substance altogether.

Not burning, it can't simply be run through.

Crystals and corrosion remain after the following tankful, and AdBlue separates back out of your diesel, so thinning it can't help. That is why the flush counts more, and turning your key "to see" costs more with AdBlue than nearly any other mistake — in East Ewell or the heart of Nork equally.

The good news is the same as with petrol.

Clearing a tank is the easiest job on a fuel system, and without running, the AdBlue stays in it — anywhere in Surrey the vehicle has stopped.

## AdBlue in a diesel tank around Nork: how it ends up there

It is not deliberate. Many cars have the AdBlue inlet alongside the diesel one, now and then behind one flap, and muddling them up is easy in poor light.

It mostly happens at home, from a bottle bought on the journey home, not at the filling station.

Usually, it takes place in one of a couple of familiar ways.

Hurrying, outside Warren Mead Junior School, after a warning lamp flashed on during the school run, a parent refills the vehicle.

Near Warren Road, someone pours a container in on the drive after work.

Or the car is topped up in the car park outside the pub in the village, in poor light, by somebody who has never opened that flap before.

It comes up most in a rental, a new motor, a company car, or the other car in a family with one of each fuels — the vehicles drivers use least.

Wherever you're in Nork or the remainder of Surrey, it is the same slip and the same first answer: leave the vehicle off.

## Nork: started the motor with AdBlue in the diesel tank?

Then the tank is no longer where the AdBlue is.

It has been pulled through the filter and the lines, and if the motor ran for any time, it has reached the high-pressure pump and the fuel injectors.

Expect lumpy running, smoke, lost power, lights on the dash, or a stall — returning from The Humps, perhaps, or part way across Nork.

No restarting to check: stop when it is safe, then turn it off.

More of that is pulled through with each start.

On the M25, under 5 miles from Nork, the first junction is where to leave, and somewhere sensible is where to stop — not carrying on.

How far it went matters. A couple of hundred yards across Nork to the car park by St Paul is a very different job from a run towards Westminster, under 15 miles away, with the AdBlue reaching further into the system with each mile.

About how far it had come is worth telling us.

There's more to rinse out once your engine has been run, and our engineers do all of it where the car has ended up.

Spotted quickly, it very seldom leaves permanent damage.

## What does an AdBlue drain on a diesel involve around Nork?

Wherever it has come to rest in Nork — a filling station, a layby, a driveway, a road beside Nork Community Centre — our van travels to the vehicle.

Three answers shape the work, and so first we ask what got in, about what quantity, and whether the motor has run.

The contaminated diesel and the urea leave as one after the tank is drained, right there.

A full flush matters far more with AdBlue than after petrol, because residue won't clear away by itself.

After that, your filter: flushed, or replaced when it must be. Then clean diesel, then a test of your car.

If your motor has not run, most jobs take about half an hour once our technicians arrive.

Explosion-proof pumps mean a live forecourt safe to work on, and they run quiet enough not to disturb the street at night.

Finally, your system is bled with new diesel.

Whether it is a parking space by Epsom Downs or a drive in Nork, that is where we start it and you set off.

The test before our technicians go is that it runs smoothly on clean diesel.

The whole job is done where the vehicle is, so it never needs to go to a garage.

Insurers ask for a VAT invoice and an engineer report, and both come at the end.

## About Nork, for a moment

Nork is a village in Surrey, situated inland at an elevation of 97 metres, approximately 13 miles south of central London. Nork lies near several notable areas, including Epsom Downs and Great Burgh, and is characterized by its predominantly semi-detached housing stock. Nork remains a relatively small community, with a population of around 1970 residents.

## Nork and Surrey: AdBlue drains across the area

AdBlue call-outs in Nork are passed to teams that serve the towns near it — North Looe, Epsom Downs plus Great Burgh — and most of Surrey further out, across SM postcodes.

Ring and check rather than guess if you are by a border, or anywhere awkward to pin down.

No towing is needed. In Nork, a rural village, a van that comes to you fits: your vehicle is emptied where it stands, whether in a driveway, a side street, a parking area or a filling station.

## What does AdBlue in a diesel tank cost to sort out in Nork?

No single figure could be fair, because every job differs.

The price moves first with how long, if at all, your engine has been running, and next with the amount of AdBlue that got in. After that it rests on where the car is and whether a van can reach it safely, which is simpler on an open drive than in a tight space behind DW Fitness - Ewell.

Ahead of any figure, never after, each enquiry from Nork opens with three questions: the liquid, the quantity, plus whether the engine ran.

Once those are known, a range turns into a single firm number.

The quote is given during the call, before anyone sets off; settling up happens on the day, by card or by phone, with nothing upfront.

Check your insurance while we're on the way: many include misfuelling cover.

## Nork: still alongside your car?

Then the most useful thing you can do is nothing to your car.

Engine off, keys out, ignition off.

Call 0333 366 0103: AdBlue, the amount, and if it ran is all we ask. Petrol in Diesel handles the remainder across Surrey, Nork included.
