# AdBlue in the Diesel Tank in Primrose Hill? Keep It Switched Off

Engine off, ignition off: that is where you start if AdBlue has gone into the diesel tank.

Water with urea mixed in it: that's AdBlue.

Unlike fuel, it neither burns nor mixes, and no harm happens till the engine pulls it through.

Caught before the engine has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the car is around Primrose Hill.

Before anything, call us on 0333 366 0103.

## Your next steps straight away, Primrose Hill: AdBlue in the diesel tank

Do:

- Remove your keys, which prevents someone switching the electrics on.

- Hazards on, if moving traffic is anywhere near.

- So you can give us which liquid it was and about what quantity, keep the till receipt or the empty bottle.

- Tell us a postcode starting DY2 9, or whatever street is nearest, and our van reaches you straight — so ring wherever you stand.

Don't do these:

- No starting the motor — not briefly, not to shift your vehicle.

- Your ignition stays off: on lots of diesels, switching it on is enough to start your fuel pump.

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

- Leave the car where it is instead of driving it anywhere, even a short way down Northcott Road.

- Draining your tank on your own by the road isn't one to try.

The staff on duty at any Primrose Hill forecourt — the BP included — will usually help rolling it aside if you ask.

If you're on your own drive, leave the vehicle exactly where it sits.

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

The motor isn't what AdBlue is made for; the exhaust is.

Its own reservoir keeps it, and from there it is sprayed into your exhaust, and there it treats the fumes.

Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

It doesn't blend. After it is poured into a tank of diesel, AdBlue acts nothing like diesel.

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

The first thing the system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Windmill End last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of that tank, and nothing has sucked it in.

From there it does two kinds of damage.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, so it keeps running on the components it hits for as long as it remains there.

Lines holding AdBlue spell harm overnight for a car sitting in Primrose Hill. Only in the tank, it stays stable.

Then there's the water: it brings no lubrication to the components that need it most — the high-pressure pump and each injector.

## AdBlue in a diesel: why it is regularly worse than petrol

Petrol pumped into a diesel on Tesco's forecourt makes the fuel thin — that's the whole problem.

Mixed through the diesel and left still, it's harmless at that stage; running your motor does the harm.

The issue with AdBlue in a diesel is a totally wrong liquid.

Not burning, it cannot just be run through.

It doesn't stay mixed, so it can't be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting your engine "to see" costs more here than nearly anywhere else, whether your car is in Baptist End or the middle of Primrose Hill.

As with petrol, there's good news.

Emptying a tank is the easiest part on any fuel system, and without running, the AdBlue remains in there — anywhere around West Midlands the vehicle sits.

## Primrose Hill: how AdBlue ends up in a diesel tank

Many motors place the AdBlue filler beside the diesel cap, now and then under one flap, and after dark the two may look the same. Nobody means it.

Mostly it takes place with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

A few familiar ways account for most cases.

Hurrying, outside Northfield Road Primary School, after a warning lamp flashed on during the school run, someone refills the car.

A bottle is poured in at the end of the day on a drive just off Old Level Way.

Else, after dark outside The Junction Inn, the car gets topped up by a driver opening that flap the first time.

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

Same slip, an identical first step — keep it off — wherever you happen to be in Primrose Hill or the remainder of West Midlands.

## Primrose Hill: started the motor with AdBlue in your diesel tank?

Then the AdBlue has left your tank.

With any running, it travels to the high-pressure pump and every injector, after passing via the fuel filter and pipework.

You may see the motor running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Golden Hillock Playing Field or halfway across Primrose Hill.

No restarting to test: stop when it is safe, then switch it off.

Each start pulls more of it through.

If you were on the M5, under 3 miles from Primrose Hill, come off at the next exit and stop somewhere sensible rather than pressing on.

Every mile carries the AdBlue further in. That's why a hop across Primrose Hill to park beside Trinity Methodist and a drive of under 10 miles towards Wolverhampton are such separate jobs.

About how far it had come is worth telling us.

Wherever the car came to a stop is where all of it gets done, even with more to flush once the motor has been running.

Permanent damage is very rare if it is caught soon.

## What draining AdBlue from a diesel involves around Primrose Hill

The car remains where it is, whether that is a road beside Faith United Chapel, a drive, a layby or a forecourt around Primrose Hill, and the van comes to it.

What got in, about the quantity, plus whether your motor has turned over: our engineers check first, since those shape the job.

On the spot, that tank is then emptied, and both the contaminated diesel and the urea come out at once.

With AdBlue, more so than with petrol, the flush matters: the fuel system is cleaned right through since residue won't flush away by itself.

Fresh diesel goes in once the fuel filter is cleaned — or swapped, when it needs to be — and after that your vehicle is tested.

Roughly half an hour once we arrive is usual for most jobs where the motor hasn't run.

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

Clean diesel goes in to bleed your system, and that's the final step.

Whether it's a parking space at Cradley Heath or a driveway around Primrose Hill, that is where our engineers fire it up and you head off.

Before we leave, our engineers confirm it's running smoothly with fresh diesel in.

No garage is required at any stage, with the entire job done on the spot.

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

## AdBlue drains across West Midlands, Primrose Hill included

Netherton, Darby End and Bowling Green are among the places around Primrose Hill that the same vans reach, together with much of West Midlands beyond, over the DY postcode area.

Ring and ask instead of guessing when you are close to a county line, or somewhere tricky to pin down.

No towing is needed. In Primrose Hill, a residential suburb, a van that comes to you fits: the vehicle is emptied on the spot, be it in a driveway, a residential street, a car park or a forecourt.

## AdBlue in a diesel tank around Primrose Hill: the cost of fixing it

Not one single price could be fair, since every job is different.

The cost changes first with how long, if at all, the engine has been running, and next with the amount of AdBlue that was put in. After that it turns on where the vehicle is and whether a van can get to it safely, which is simpler on an open driveway than in a tight gap behind Titanic anchor.

With that reason, every call from Primrose Hill begins by asking the identical trio — what got in, what quantity, whether it ran — before any figure.

Once they are known, a range turns into one fixed number.

Our quote is quoted on the call, before anyone leaves; payment happens on the day, by card or by phone, and nothing upfront.

Misfuelling cover is part of plenty of insurance policies, so it pays to look at yours before the van gets there.

## Primrose Hill: still alongside the car?

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

Engine off, keys out, ignition off.

Phone 0333 366 0103 then tell us it's AdBlue, about how much, and if it has run. Petrol in Diesel takes it from there, around Primrose Hill or anywhere around West Midlands.
