# AdBlue in the Diesel Tank in Cromer? Keep It Switched Off

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

Urea dissolved in water is what AdBlue is.

Not like fuel, it neither burns nor mixes, and nothing happens till your engine sucks it through.

In Cromer, AdBlue in a diesel tank found before your motor runs usually means a drain and a thorough flush, right where the vehicle is.

First, phone us on 0333 366 0103.

## Those opening minutes: AdBlue in your diesel tank around Cromer

To do:

- Pull your keys out, so nobody switches your ignition on.

- Hazards on, if moving traffic is at all close.

- The empty bottle or the receipt shows us the product and the quantity, so do not throw it away.

- Call just where you are. Quote a NR27 9 postcode or the nearest street name, and no one has to hunt for you.

Not to do:

- Do not start the engine, even for a moment to move the vehicle.

- Don't switch your ignition on. On many diesels that alone runs the fuel pump.

- Pouring in more diesel does not work: AdBlue settles out instead of blending.

- Any driving at all is best avoided, including a short way up Church Street.

- No draining it yourself, either, on the verge.

Get the attendants to help you move your vehicle off the island if you are at a forecourt in Cromer, whether it is the Morrisons or somewhere else.

If you're on your own drive, leave it exactly where it is.

## AdBlue in a diesel tank, and what it does there

The engine is not what AdBlue is made for; the exhaust is.

Kept in a separate tank, it's injected into the exhaust stream to treat the fumes.

A fuel pump isn't designed to take it, and AdBlue was never supposed to go through one.

Fuel mixes; AdBlue, once poured in, will not. The behaviour is nothing like fuel's.

The pickup takes fuel from the deepest part of that tank, and that's precisely where AdBlue settles: being heavier than diesel, it sinks.

A vehicle topped up on a driveway in Crossdale Street yesterday evening and not started since is the simple one. No pump has sucked the AdBlue up yet — though when the motor turns, that is what goes first, directly from the bottom of that tank.

From there it causes two kinds of harm.

It eats at certain metals found in fuel components, attacking any part it touches until it's cleared completely. And once the water goes, the urea forms crystals that block filters and settle in tiny channels.

Lines carrying AdBlue mean damage by morning for a vehicle parked around Cromer. Just in your tank, it stays stable.

Diesel protects the injection pump and each injector as it flows; water offers no lubrication, and that is a separate kind of harm.

## Why AdBlue in a diesel is frequently more major than petrol

An issue of thin fuel is what you end up with from fuelling a diesel with petrol from the another forecourt nearby.

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

With AdBlue in a diesel, the fluid as such is simply the wrong one.

Not burning, it cannot just be run through.

It doesn't stay mixed, so it can't be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting the engine "to see" costs more here than almost anywhere else, whether your car is in Overstrand or the middle of Cromer.

The same good news applies as with petrol.

Clearing a tank is the simplest part on any fuel system, and with no start-up, the AdBlue stays in it — anywhere around Norfolk your car sits.

## How AdBlue ends up in a diesel tank around Cromer

In dim light, two caps together — the AdBlue cap and the diesel cap, occasionally behind one flap — can look the same. No one intends it; many layouts allow it.

Usually it is never the forecourt: a driver picks up a bottle heading home and pours it in outside the house.

The ways it takes place are few and familiar.

Halfway through the morning drop-off, the dashboard flags it up, and outside Cromer Junior School the top-up is rushed.

A bottle is poured in at the end of the day on a drive just off Chapel Street.

Another version: darkness, a pub car park by Cromer Social Club, and someone using that flap for the first time.

The least familiar cars see it the most — hire cars, brand-new cars, company ones, and the other vehicle of a family with both fuels.

Wherever you are in Cromer or the remainder of Norfolk, it is the same slip and the same first answer: leave the car off.

## AdBlue in the diesel tank in Cromer, and the motor started?

In that case, the AdBlue is no longer in your tank.

With any running, it goes on to the high-pressure pump and each injector, having passed through the filter and pipework.

Maybe returning from Cromer Cricket Club, or midway across Cromer, your engine might go lumpy, smoke, lose pace, flash your dash or cut out.

Stop as soon as it is safe, switch off, and don't restart the car to check.

With each start, more of that is pulled through.

If you were on the M11, over 50 miles from Cromer, come off at the next junction and stop somewhere safe instead of pressing on.

Every mile pushes the AdBlue further into your system. That is why crossing Cromer to park beside Cromer Community Centre and a drive of under 25 miles towards Norwich are such distinct jobs.

Roughly how far had it come? Tell us.

There is more to clean out once your engine has run, and we do all of it where the vehicle has come to a stop.

Very seldom does it leave lasting damage when it is spotted quickly.

## What does an AdBlue drain on a diesel involve in Cromer?

Anywhere it has come to rest in Cromer — a forecourt, a lay-by, a drive, a road by Cromer Library — the van comes to your vehicle.

The work rests on three replies, which our engineers get first — which fluid got in, the amount, and whether the motor has turned over.

On the spot, your tank is then drained, and both the polluted diesel and the urea leave at once.

With AdBlue, far more than with petrol, the flush matters: the whole system is cleaned all the way through because what remains won't wash out by itself.

Clean diesel goes in after your filter is flushed — or swapped, if it needs to be — and then your vehicle is tested.

About half an hour once we arrive is usual for most jobs when the engine hasn't run.

Low-noise enough for use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.

The final step is to bleed your system on clean diesel.

You head off as soon as our technicians have started the car, and it makes no difference whether your car is on a driveway around Cromer or in a bay outside the nearest station.

It's checked on clean diesel to make sure it runs properly before our engineers leave.

Our technicians do it all wherever the vehicle has ended up, and it never needs to be taken to a workshop.

You get a VAT invoice and an engineer report later on, which is what insurers want.

## About Cromer, briefly

Cromer is a coastal town in Norfolk, situated on the north-east coast of England, with an elevation of around 22 metres above sea level. Cromer lies approximately 20 miles north of Norwich and 115 miles north-east of London, making it a popular destination for those seeking a seaside retreat. Cromer is characterised by its predominantly detached housing stock and is surrounded by nearby places such as Suffield Park, East Runton, and Felbrigg. Cromer has a population of around 6601 residents.

## Cromer and Norfolk: AdBlue drains across the area

The vans that answer AdBlue call-outs around Cromer also cover the locations around it, Suffield Park, East Runton and Felbrigg among them, and most of Norfolk beyond, across the NR postcode area.

Guessing doesn't help by a border or anywhere hard to describe; ring and ask.

No moving is needed. In Cromer, a coastal town, a mobile service fits: the vehicle is emptied on the spot, be it on a drive, a residential street, a car park or a forecourt.

## What AdBlue in a diesel tank costs to put right in Cromer

Every job differs, so not one fixed quote would be honest.

What moves the price is, first, whether the motor has run and for how long; then how much AdBlue got in; and then where the vehicle is and whether a technician can get to it safely, which is easier on an open driveway than in a tight space behind Regal Movieplex.

What was put in, what quantity, and whether it ran: every Cromer call begins by asking exactly those, ahead of any figure, never afterwards.

The replies turn a range into a straight price.

You hear that price by phone, before anyone sets off, and you pay on the day, by card or by phone, with nothing upfront.

Check your insurance while we are on the way: many carry misfuelling cover.

## Still beside your car in Cromer?

Then, touch nothing — that is the most helpful move there is.

Engine off, keys out, ignition off.

Ring 0333 366 0103: AdBlue, roughly how much, plus whether the engine ran is all our engineers ask. Petrol in Diesel handles the remainder throughout Norfolk, Cromer too.
