# Pebsham: AdBlue in the Diesel Tank? Leave It Off

AdBlue in the diesel tank? Then leave the motor off — and your ignition too.

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

As it is water-based, it will not ignite and never combines with diesel; trouble only starts when the pump starts pulling it.

If the engine has not run yet, AdBlue in a diesel tank is usually drained and carefully rinsed where the vehicle stands in Pebsham.

No step comes before calling 0333 366 0103.

## Your next steps right now, Pebsham: AdBlue in the diesel tank

Things to do:

- Pocket the keys, which stops anyone switching the power on.

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

- Hold on to your receipt or the empty bottle, and so you can tell us what went in and roughly how much.

- The van locates you quickest with a postcode starting TN40 2, or simply the name of a street close by, and so phone from the spot.

Things not to do:

- No starting your engine — not for a second, not to shift the car.

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

- No extra fuel on top. The AdBlue won't blend, and so it is pointless.

- Keep the vehicle where it is instead of driving it anywhere, even a short stretch down Haslam Crescent.

- By the road, don't attempt draining it yourself.

Rolling the vehicle away from the island is a job for staff to help with, whichever Pebsham forecourt you are on, the Esso included.

On that drive, the car remains just as it is.

## What does AdBlue do in a diesel tank?

Not your engine but your exhaust is where AdBlue belongs.

Stored in a dedicated tank, it's injected into the exhaust to treat the fumes.

No part in an injection pump is made for this liquid — and no part of it was meant to go through one.

Poured in with the diesel, it stays apart rather than mixing — quite different from fuel.

Denser than diesel, it sinks and pools below it — the very place the pickup sucks from.

When your pump runs, the AdBlue is top of the list to go through. Before then it sits beneath the diesel, which is how a vehicle topped up in Sidley yesterday and never started stays the simple case, as long as no one turns the key.

From there it causes 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, and so it keeps labouring on the parts it hits for as long as it stays there.

A motor left standing in Pebsham with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't.

Water protects nothing. The high-pressure pump and every injector depend on diesel flowing through them, so the water part harms them in its own right.

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

Petrol pumped into a diesel on BP's forecourt makes the fuel thin — that's the main fault.

It mixes with your diesel, and while it's inside your tank it causes no damage; the harm comes from running the motor on it.

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

Not burning, it cannot just be run through.

Deposits and corrosion remain through the next tankful, and AdBlue splits again out of the diesel, so thinning it won't work. Hence the flush counts so much, and turning the key "to see" costs more with AdBlue than nearly any other mistake — in Harley Shute or the heart of Pebsham alike.

The same good news holds as with petrol.

Not started? Then the AdBlue waits just inside the tank, the simplest section of the whole system to empty, wherever the car has stopped in East Sussex.

## How does AdBlue end up in a diesel tank in Pebsham?

It's not deliberate. Plenty of vehicles have the AdBlue inlet alongside the diesel one, occasionally under one flap, and mixing them up is easy in poor light.

Most of the time it occurs with a bottle bought on the way home and poured in on the drive, not at the forecourt.

The ways it takes place are few and familiar.

A warning light comes on during the school run, and the top-up occurs in a hurry outside St Mary Magdalene Catholic Primary School.

A driver tips the container in at home, just off Bishops Walk, as the day ends.

Or someone unfamiliar with that flap refills the car in dim light, stopped in the car park by The Bull Inn.

Rented motors, brand-new motors, fleet vehicles, or the second car in a family with both fuels: the least familiar cars see it the most.

Wherever you're around Pebsham or the rest of East Sussex, it is the same error and the same first answer: leave the vehicle off.

## Already started the engine with AdBlue in your diesel tank in Pebsham?

Then the tank is no longer where the AdBlue is.

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

Watch for rough running, smoke, falling power, lights on the dash, or a stall — returning from Seabourne Road Recreation Ground, say, or midway across Pebsham.

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

Every start pulls more of it through.

On the M20, under 50 miles from Pebsham, the first junction is where to exit, and anywhere safe is where to stop — not carrying on.

A quick hop across Pebsham to the car park by Pebsham Community Hub is one matter; heading for Brighton and Hove, under 50 miles away, is something else, since each mile pushes the AdBlue deeper in. So distance counts.

Approximately how far had it come? Tell us.

Once the motor has been run, the flush includes more, and all of it is done where the vehicle has stopped.

Very rarely does it leave permanent damage if it's noticed quickly.

## Pebsham: how AdBlue is cleared from a diesel

Anywhere it has stopped around Pebsham — a forecourt, a layby, a driveway, a street beside St. Michael and All Angels Church — the van travels to your vehicle.

Before anything else we ask what was put in, roughly how much, and whether your engine has been run, because those answers determine the work.

Then the tank is emptied where your car sits, so the contaminated fuel and the AdBlue come out together.

With AdBlue, far more than with petrol, flushing counts: the fuel system is flushed right through since residue will not flush out unaided.

Fresh diesel goes in after the fuel filter is cleaned — or swapped, if it needs to be — and after that the car is tested.

If your engine hasn't run, most jobs take about half an hour once our technicians are there.

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

The final step is to prime the fuel system on new diesel.

Starting the engine comes next, and then you set off from where the car is parked, outside Bexhill or on a driveway in Pebsham.

It's checked on fresh diesel to confirm it runs correctly before we leave.

Our engineers do it all wherever your car has stopped, and it never has to go to a garage.

You receive a VAT invoice and an engineer report after that, which is what insurers want.

## About Pebsham and where it is

Pebsham is a coastal suburban area in East Sussex, situated near the towns of Hastings and Bexhill-on-Sea. Pebsham lies at a low elevation of around 20 metres, close to the Glyne Gap and Old Town. Pebsham is characterized by its predominantly detached housing stock, reflecting the area's residential nature. Pebsham is also near the Bulverhythe area, with Brighton and Hove located approximately 28 miles to the west.

## AdBlue drains around Pebsham and across East Sussex

The teams that answer AdBlue call-outs around Pebsham also cover the locations around it, Glyne Gap, Old Town and Bulverhythe among them, and most of East Sussex beyond, across the TN postcode area.

If you're near a border, or somewhere hard to explain, ring and ask instead of guessing.

Pebsham is a residential suburb, and an on-site drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it sits, and so it never needs to be moved to us.

## Pebsham: what AdBlue in a diesel tank costs to fix

No single price would be honest, since each job is different.

Whether your engine has been running, and for how long, comes first in what shifts the price. How much AdBlue went in comes next, and then the location of the car, because an open drive is simpler for a van to get to safely than a tight space behind Battle Abbey School Swimming Pool.

That's why each call from Pebsham starts with the same three queries, asked before giving a figure, not after: what was put in, how much, and whether it has run.

When those are answered, a range becomes a single fixed figure.

Priced by phone before the engineer heads out, it is settled on the day — card or phone, nothing in advance.

Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way.

## In Pebsham and still alongside your car?

Then, the most helpful thing to do with the vehicle is to not touch it.

Ignition off, motor off, keys out.

Say it was AdBlue, about what quantity, and whether the engine ran, on 0333 366 0103. After that Petrol in Diesel takes over, in Pebsham or wherever in East Sussex.
