# Don't Start It: AdBlue in a Diesel Tank in Trillick

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

Urea dissolved in water is all AdBlue is.

The harm starts once it's sucked through the pump — it will not ignite, and it will not combine with diesel.

In Trillick, AdBlue in a diesel tank caught before the motor runs usually comes down to a drain and a thorough flush, right where the vehicle is.

Before you do anything else, ring 0333 366 0103.

## AdBlue in your diesel tank around Trillick: the first few minutes

Do:

- Remove the keys, which stops anyone turning the electrics on.

- Hazards on, if moving traffic is anywhere near.

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

- Our van finds you fastest with a postcode starting BT78 3, or simply the name of a street nearby, so phone from the spot.

Not to do:

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

- Do not switch your ignition on. On plenty of diesels that alone runs the fuel pump.

- Pouring in more diesel doesn't help: AdBlue settles out rather than blending.

- Do not drive the car anywhere, not even a short way along Crown Street.

- Emptying that tank yourself beside the road is not worth trying.

Rolling the vehicle off the island is a job for staff to help with, wherever Trillick forecourt you are on, the the nearest petrol station or any other.

At your own drive, do not move it at all.

## AdBlue in a diesel tank: what it does

AdBlue is made for the exhaust, not your engine.

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

No part inside an injection pump is made for this fluid — and no part of that was intended to go that way.

Fuel blends; AdBlue, once tipped in, will not. Its behaviour is nothing like fuel's.

It drops, since it is denser than diesel, and pools down where the intake draws its supply from.

A vehicle filled on a driveway in Tempo overnight and left unstarted counts as the straightforward one. No pump has pulled the AdBlue up yet — though when your motor runs, that's what is pulled first, straight from the bottom of the tank.

Two kinds of damage follow from there.

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

Lines holding AdBlue spell damage overnight for a vehicle parked in Trillick. Just inside that tank, it stays stable.

Diesel lubricates the high-pressure pump and each injector as it passes; water gives no lubrication, and that is a second kind of harm.

## Petrol or AdBlue in a diesel: why AdBlue is often worse

Petrol put into a diesel on another forecourt nearby's forecourt makes the fuel thin — that is the whole problem.

Mixed through the diesel and left still, it's no threat for now; running your engine is the harm.

AdBlue in a diesel is an issue of the wrong substance altogether.

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

Whether your vehicle is in Irvinestown or the centre of Trillick, turning it over "to see" does more harm in this case than almost any other error, and the flush matters for more. Why: it will not stay blended, so diluting it fails; and crystals and corrosion outlast the next tankful.

With AdBlue, the good news is no distinct from petrol.

If the motor hasn't run, the AdBlue is still in the tank, and that tank is the easiest part of a fuel system to clear, wherever in County Tyrone the vehicle is sitting.

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

No one means to do it. The AdBlue filler on many vehicles waits right next to your diesel filler, sometimes under the same flap, and the two caps can look alike in poor light.

Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the forecourt.

The ways it occurs are few and familiar.

A warning light comes on during the school run, and the top-up happens in a hurry outside the local primary school.

After work, a bottle goes in on a driveway near Rock Street.

Another pattern: dim light, a pub car park outside the pub in the village, and someone using that flap for the first time.

Hired vehicles, brand-new motors, fleet vehicles, or the spare vehicle in a home with one of each: the least known cars get it the most.

Wherever in County Tyrone, Trillick included, the mistake doesn't change, and neither does the first step: leave it off.

## Already started your engine with AdBlue in your diesel tank in Trillick?

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

The filter and lines have had it sucked along, and some running takes it on to the high-pressure pump and every injector.

Expect lumpy running, smoke, lost power, lights on your dash, or a cut-out — returning from the green space at the edge of the village, say, or part way across Trillick.

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

With each start, more of it is pulled through.

Leave the M77, over 50 miles from Trillick, by the first junction and park safely, rather than driving on.

Mileage counts: every mile carries the AdBlue further in, and so heading for Armagh, under 50 miles away, makes a much larger job than crossing Trillick to the car park by the centre.

Roughly how far it had come is worth telling us.

Wherever your car came to a stop is where all of it gets done, even with more to clean out after the motor has been run.

Noticed quickly, it very seldom leaves long-term damage.

## What draining AdBlue from a diesel involves in Trillick

Our technicians come to your car, wherever it has stopped around Trillick: a side street near a street just off the centre, a drive, a lay-by or a forecourt.

The work depends on three replies, which we ask for before all else — what went in, the quantity, and if the engine has run.

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

The fuel system is cleaned thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own.

Testing the vehicle follows at the end, once clean diesel goes in and the filter is cleaned or, where necessary, swapped.

Roughly half an hour on site is typical for most jobs when your engine hasn't run.

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

Finally, the fuel system is primed with new diesel.

After that our engineers start the engine and you head off, whether from a parking space outside the nearest station or a driveway around Trillick.

Before we leave, our technicians confirm it is running smoothly with fresh diesel in.

No garage is required at any stage, with the whole job done then and there.

Afterwards, you are given paperwork for your insurer: a VAT invoice and a report from the engineer.

## AdBlue drains across Trillick and County Tyrone

AdBlue call-outs in Trillick are passed to teams that cover the towns near it — Kilskeery, Dromore as well as Ballinamallard — and much of County Tyrone beyond, across BT postcodes.

Close to a border, or somewhere awkward to pin down? Asking beats guessing, so ring.

No towing is needed. In Trillick, a small village, a mobile service fits: the vehicle is drained where it stands, be it in a driveway, a residential street, a car park or a forecourt.

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

No flat figure could be fair, since each job differs.

What moves the cost is, first of all, whether your engine has been running and for how long; then how much AdBlue was put in; and then where the car is and whether a technician can get to it safely, which is simpler on an open drive than in a tight gap behind the far end of the built-up part.

Which fluid was put in, how much, and whether it ran: every Trillick enquiry begins by asking exactly those, before any figure, never after.

With them, the range narrows to one fixed number.

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

Check your policy whilst we are on the way: many carry misfuelling cover.
