# Thorpe on the Hill: AdBlue in the Diesel Tank? Leave It Off

Engine off, ignition off: that is how you begin if AdBlue has got into your diesel tank.

Urea dissolved in water is all AdBlue is.

As it is water-based, it will not burn and won't blend with diesel; trouble just starts when the pump starts drawing it.

If your motor hasn't run yet, AdBlue in a diesel tank is usually drained and carefully cleaned where your car sits around Thorpe on the Hill.

First, phone us on 0333 366 0103.

## Those opening minutes: AdBlue in your diesel tank in Thorpe on the Hill

To do:

- So no one can turn the ignition on, pull the keys out.

- Close to moving traffic? So put the hazards on.

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

- Ring right where you are. Quote a WF3 3 postcode or the nearest street sign, and no one has to search for you.

Do not:

- Moving your vehicle even a few yards is no reason to start the motor.

- Many diesels run their pump the moment the ignition comes on, so keep it off.

- Do not top up with diesel to dilute it. AdBlue doesn't mix in diesel; it separates out.

- Do not drive the vehicle anywhere, not even a short distance down Gascoigne Road.

- Draining that tank yourself beside the road isn't one to try.

Ask the people behind the counter to help you move the car away from the island if you are at a forecourt in Thorpe on the Hill, whether it is the Robin Hood Service Station or somewhere else.

At home, your car stays just where it is.

## What AdBlue does in a diesel tank

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

From a separate reservoir it goes directly to the exhaust, cleaning what the engine emits.

No part inside an injection pump is made for this fluid — and none of it was intended to travel that way.

Tipped in with the diesel, it stays separate instead of mixing — entirely unlike fuel.

Denser than diesel, it sinks and collects below it — the same spot the intake sucks from.

A car topped up on a drive in Robin Hood yesterday evening and left unstarted is the simple one. No pump has pulled the AdBlue up so far — but once your engine turns, that's what goes first, straight from the bottom of that tank.

Once it is pulled in, the harm takes two forms.

Crystals and corrosion. As the water evaporates, it strands urea that hardens in filter elements and tiny channels; meanwhile, since it attacks some metals, each part it reaches keeps suffering for as long as it stays in there.

If the AdBlue is in the lines, leaving it overnight around Thorpe on the Hill leaves things worse. Inside your tank only, time costs nothing.

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

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

Top up a diesel with petrol by mistake over at the BP, and this problem is thinned fuel.

Blended through your diesel and left still, it is no threat at that stage; running the motor does the harm.

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

Because it does not burn, running it through is not an option.

Deposits and corrosion stay after the next fill, and AdBlue separates again from the diesel, and so thinning it won't work. Hence the flush matters more, and turning the key "to see" does more harm here than nearly any other slip — in Lawns or the heart of Thorpe on the Hill equally.

The same good news applies as with petrol.

Clearing a tank is the easiest part on a fuel system, and without start-up, the AdBlue stays in there — anywhere around West Yorkshire your vehicle has stopped.

## Thorpe on the Hill: how AdBlue ends up in a diesel tank

It is not deliberate. Plenty of vehicles keep the AdBlue inlet beside the diesel inlet, now and then behind a single flap, and mixing them up is easy after dark.

A bottle picked up while driving home and poured in outside the house, rather than at the forecourt, is the usual route.

A couple of familiar ways cover most cases.

Hurrying, outside Thorpe Primary School, after a warning light came on during the school run, a parent refills the car.

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

Or your car is topped up in the car park at The Bedford Arms, in poor light, by somebody who has never opened that flap before.

It occurs most in the vehicles motorists know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol.

Wherever around West Yorkshire, Thorpe on the Hill included, the mistake doesn't change, and nor does the first step: leave it switched off.

## Already started the engine with AdBlue in your diesel tank around Thorpe on the Hill?

The AdBlue has left the tank, then.

The fuel filter and lines have had it sucked along, and some running time carries it on to the injection pump and each injector.

Watch for rough running, smoke, lost power, warnings on your dash, or a stall — returning from Kiddow Spring, perhaps, or midway across Thorpe on the Hill.

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

With each start, more of it is pulled through.

Thorpe on the Hill sits under a mile from the M62; if you were on it, leave at the next junction and pull up safely instead of driving on.

Distance matters: every mile carries the AdBlue deeper in, so heading for Wakefield, under 5 miles away, gives a far bigger job than crossing Thorpe on the Hill to the car park by Thorpe Library & Community Centre.

Tell us roughly how far it had come.

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

If it is spotted soon, permanent damage is very rare.

## What emptying AdBlue from a diesel involves around Thorpe on the Hill

Anywhere it has come to rest in Thorpe on the Hill — a filling station, a lay-by, a driveway, a street by St Gabriels Community Centre — the van travels to your car.

Before anything else we ask what was put in, about how much, and if your motor has run, since those replies determine the work.

On the spot, the tank is then emptied, and both the contaminated diesel and the urea come out as one.

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

Clean diesel goes in once the filter is cleaned — or replaced, if it needs to be — and then your car is tested.

If the motor has not run, most jobs take about half an hour once our technicians arrive.

The equipment is explosion-proof, so a live forecourt is no fault, and it's quiet enough for a residential street after dark.

Bleeding the system with fresh diesel comes last.

Whether it is a parking bay at Outwood or a driveway in Thorpe on the Hill, that is where our engineers fire it up and you drive off.

Our engineers confirm it runs correctly on clean diesel before we go.

No workshop is needed at any point, with the whole job done then and there.

Your insurer is likely to want an engineer's report and your VAT invoice — both yours afterwards.

## What does AdBlue in a diesel tank cost to sort out around Thorpe on the Hill?

Each job is different, so not one single price is fair.

The price shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that was put in. After that it turns on where your car is and whether our van can get to it safely, which is easier on an open driveway than in a tight space behind East Ardsley St Gabriels Church Youth Club.

Which fluid went in, what quantity, plus if it ran: each Thorpe on the Hill call opens by asking exactly those, ahead of a quote, not afterwards.

The answers turn a range into a straight price.

You hear that quote by phone, before anybody heads out, and you pay on the day, by card or over the phone, with nothing upfront.
