# Newton St Faith: AdBlue in the Diesel Tank? Leave It Off

AdBlue in your diesel tank? Then keep the engine off — and the ignition too.

Chemically, AdBlue is just urea in water.

It does not burn, it doesn't mix with diesel, and the damage it does starts when the system pulls it in.

In Newton St Faith, AdBlue in a diesel tank caught before the motor runs normally comes down to a drain and a thorough flush, just where your car is.

Before you do anything else, phone 0333 366 0103.

## What to do straight away, Newton St Faith: AdBlue in your diesel tank

To do:

- Take your keys out, so no one switches your ignition on.

- Put the hazards on if you're anywhere close to moving traffic.

- The empty bottle or the till receipt shows us the fluid and the quantity, and so do not bin it out.

- Ring us from where you are. A postcode starting NR10 3, or the name of the closest street, gets the van to you without a search.

Not to do:

- Shifting the car just a short way is no reason to fire up the engine.

- Your ignition stays off: on many diesels, turning it on is enough to run your fuel pump.

- AdBlue doesn't mix in diesel — it separates out — so adding more fuel won't weaken it.

- Any driving at all is to be avoided, even a short distance along Manor Road.

- Do not try to drain the car yourself by the roadside.

Rolling your vehicle away from the island is a job for staff to help with, wherever Newton St Faith forecourt you are on, the Applegreen included.

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

## What does AdBlue do in a diesel tank?

Meant for your exhaust, AdBlue has no business in your engine.

Its own tank holds it, and from there it's sprayed into the exhaust, and there it cleans the gas.

Not one side fits the other: urea doesn't belong in an injection pump, and a pump can't deal with urea.

Tipped in with the diesel, it keeps apart instead of blending — quite unlike fuel.

It is heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup draws fuel from.

A vehicle filled on a drive in Waterloo overnight and not started since counts as the simple case. Nothing has pulled the AdBlue up yet — though when the motor turns, that is what goes first, directly from the bottom of that tank.

After it's drawn in, the damage takes two forms.

Crystals and corrosion. As the water dries, it strands urea that crystallises in filter elements and narrow passages; meanwhile, because it eats at certain metals, every part it touches suffers for as long as it stays in there.

A vehicle left sitting around Newton St Faith with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't.

Then there's the water: it offers no lubrication to the components that rely on it the most — the high-pressure pump and every injector.

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

Put petrol in a diesel at the JET and you have a problem of thin fuel.

Blended through the diesel and left still, it is no threat at that stage; using your engine does the damage.

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

Not burning, it cannot simply be run through.

Deposits and corrosion stay after the following tankful, and AdBlue separates back out of your diesel, so watering it can't help. That is why the flush counts more, and turning your key "to see" costs more here than nearly any other mistake — in Horsford or the centre of Newton St Faith equally.

The good news is the same as with petrol.

Clearing a tank is the easiest part on a fuel system, and without start-up, the AdBlue stays in it — wherever in Norfolk your car has stopped.

## How AdBlue ends up in a diesel tank in Newton St Faith

It's not deliberate. Plenty of vehicles have the AdBlue cap beside the diesel inlet, occasionally behind one flap, and mixing them up is easy after dark.

It mostly happens outside the house, from a container bought on the journey home, not at the forecourt.

A couple of familiar ways cover the majority of them.

Hurrying, outside St Faiths CofE Primary School, after a warning light flashed on during the school run, someone refills the vehicle.

In the evening, a bottle goes in on a drive near Cromer Road.

Or a driver unfamiliar with that flap tops up your vehicle after dark, stopped in the car park outside The Black Swan Inn.

It happens most in the motors people know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol.

Wherever you are around Newton St Faith or the rest of Norfolk, it is the same slip and the same first answer: leave the car off.

## AdBlue in the diesel tank in Newton St Faith, and your engine started?

The AdBlue has left the tank, then.

Via your filter, through the pipework, and — given any running — on to the high-pressure pump and every injector: that's how far it travels.

You may see the engine running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from The Lows or halfway across Newton St Faith.

No starting it again to test: stop once safe, then switch everything off.

Each start pulls more of it through.

On the M11, over 50 miles from Newton St Faith, the first junction is where to exit, and somewhere sensible is where to stop — not driving on.

How far it went matters. A couple of hundred yards across Newton St Faith to the car park by St.Faith / Newton Village Sign is a very different job from a run towards Norwich, under 10 miles away, with the AdBlue reaching further into your system with each mile.

Roughly how far it had come is worth telling us.

Once the motor has run, the flush covers more, and all of it is done where your car has stopped.

Caught early, it very rarely leaves long-term damage.

## What emptying AdBlue from a diesel involves around Newton St Faith

Wherever it has come to rest around Newton St Faith — a filling station, a layby, a drive, a road beside St Faiths Centre Horsham & Newton — our van comes to your car.

Which fluid got in, roughly how much, and if your motor has turned over: our engineers check before all else, because those shape the work.

Then the tank is drained where the car stands, so the polluted fuel and the AdBlue come out together.

Residue from AdBlue won't flush away by itself, and so the whole system gets a full flush, which matters far more with urea than with petrol.

Clean diesel goes in once the filter is flushed — or replaced, when it needs to be — and after that the vehicle is tested.

Not run? Then count on roughly half an hour once we are there for most jobs.

The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house at night.

Fresh diesel goes in to prime the fuel system, and that is the final step.

Starting the engine comes next, and then you head off from where the car is parked, by Salhouse or on a drive around Newton St Faith.

Our engineers confirm it runs smoothly on fresh diesel before leaving.

Since the job is done in its entirety where the vehicle is, a workshop never comes into it.

The insurer will want an engineer's report and the VAT invoice — both yours afterwards.

## AdBlue drains across Newton St Faith and Norfolk

New Hainford, Hainford and Horsham St Faith are among the towns around Newton St Faith that the same teams reach, along with most of Norfolk beyond, throughout the NR postcode area.

If you are close to a border, or somewhere hard to describe, ring and ask rather than assuming.

Newton St Faith is a rural village, and a mobile drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it stands, so it never needs to be moved to us.

## What AdBlue in a diesel tank costs to put right in Newton St Faith

Each job is different, and so not one single price is honest.

Three things move the price: whether the motor has been running and for how long, how much AdBlue was put in, and where the vehicle is. That last one rests on whether our van can reach it safely, and an open driveway is easier than a tight space behind Castle Hill.

Ahead of any quote, never afterwards, every call from Newton St Faith begins with three checks: the fuel, the amount, and if the engine ran.

When those are known, a range becomes a single firm number.

Priced by phone before the van sets out, it is settled that day — card or phone, no deposit.

As our engineer is travelling, check your policy: many cover misfuelling.

## Still beside the car in Newton St Faith?

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

Keys out, motor off, ignition off.

Call 0333 366 0103 then tell us it's AdBlue, roughly how much, and whether it's run. Petrol in Diesel takes it from there, in Newton St Faith or anywhere around Norfolk.
