# AdBlue in the Diesel Tank in Grove Park? Keep It Switched Off

If AdBlue has gone into your diesel tank, leave the motor off and leave your ignition off.

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

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

A drain and a thorough flush, done where the car is in Grove Park, is usually what AdBlue in a diesel tank needs — if it's caught before the motor has run.

Nothing comes before calling 0333 366 0103.

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

Things to do:

- So no one can switch your ignition on, take the keys away.

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

- Which fluid, and roughly how much amount? Hang on to the bottle or the receipt, and we will know.

- Call just where you are. Quote a SE12 9 postcode or the closest street name, and nobody has to search for you.

Things not to do:

- Don't start your engine, even for a moment to move the vehicle.

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

- No extra fuel added. The AdBlue won't mix, so it is wasted.

- Keep the car where it is rather than driving it anywhere, even a short distance along Marbrook Court.

- Beside the road, do not try draining it on your own.

The attendants working at any Grove Park forecourt — the Esso included — will usually help pushing it clear if you ask.

On the drive, your car remains exactly where it is.

## What AdBlue does in a diesel tank

Not the motor but the exhaust is where AdBlue belongs.

From a separate tank it is fed directly to the exhaust, cleaning what your engine lets out.

A fuel pump is not designed to cope with it, and AdBlue was never supposed to travel through one.

It does not combine. After it's poured into a tank of diesel, AdBlue acts not at all like diesel.

It sinks, since it's denser than diesel, and settles down where the pickup takes its fuel from.

A motor filled on a driveway in Horn Park yesterday evening and not started since is the straightforward case. No pump has sucked the AdBlue up so far — but once your motor turns, that is what goes first, directly from the bottom of that tank.

From there it does two kinds of harm.

What is left when the water goes is urea, which forms crystals: they lodge in tiny channels and clog filters. On top of that, it attacks certain metals in the fuel system, and carries on until it is cleared out.

Where the AdBlue is in the pipework, leaving it overnight in Grove Park makes things worse. Inside your tank alone, time does nothing.

Water lubricates nothing. The injection pump and each injector depend on diesel flowing through them, and so the water content damages them by itself.

## AdBlue in a diesel: why it's frequently worse than petrol

Fill a diesel with petrol in error over at the Shell, and this problem is diluted fuel.

It mixes with your diesel, and while it is inside that tank it does no damage; the harm comes from running the motor on it.

The trouble with AdBlue in a diesel is a totally unsuitable liquid.

It cannot just be run through, since it does not burn.

Nor can it be watered down, since it separates again — and the next tankful won't rinse away deposits or corrosion. So the flush counts more here, and turning your key "to see", in the centre of Grove Park or out in Middle Park, does more harm than nearly any other error.

As with petrol, there's good news.

Anywhere in Greater London the car has stopped, an unstarted engine means the AdBlue still inside the tank: the easiest part of any fuel system to empty.

## AdBlue in a diesel tank in Grove Park: how it ends up there

Nobody means to do it. The AdBlue filler on plenty of cars waits right next to your diesel filler, sometimes under the same flap, and the two caps can look alike in poor light.

A bottle bought while driving home and poured in outside the house, rather than at the filling station, is the typical story.

A couple of familiar ways account for most cases.

Rushing, outside Marvels Lane Primary School, after a warning lamp came on during the school run, someone refills the vehicle.

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

Or the car is topped up in the car park at Downham Tavern, in poor light, by someone who has never opened that flap before.

The least known vehicles see it the most — hire cars, brand-new ones, fleet cars, and the spare motor of a family with one of each fuel types.

Wherever you are in Grove Park or the rest of Greater London, it's the same slip and the same first answer: leave it off.

## Already started the engine with AdBlue in the diesel tank around Grove Park?

Then the AdBlue has left your tank.

Via the filter, through the pipework, and — with any running — on to the high-pressure pump and each injector: that's where it has gone.

Rough running, smoke, lost power, dashboard warnings or cutting out: any might show up, maybe part way across Grove Park or coming back from Desmond Tutu Peace Garden.

No starting it again to test: stop when safe, then turn everything off.

Every start pulls more of that through.

Grove Park sits under 10 miles from the M20; if you were on it, exit at the next junction and pull up safely instead of driving on.

Hopping across Grove Park to the car park by St Augustine is one thing; heading for London, under 10 miles away, is another, because each mile pushes the AdBlue further in. So mileage matters.

Tell us roughly how far it had come.

Wherever the vehicle came to a halt is where all of it gets done, even with more to flush after the engine has been started.

Spotted soon, it very seldom leaves lasting damage.

## What clearing AdBlue from a diesel involves in Grove Park

Anywhere it has come to rest in Grove Park — a forecourt, a layby, a drive, a road beside Grove Park Library — the van comes to your car.

The work rests on three answers, which our technicians get first — which fluid went in, the quantity, and if your engine has turned over.

The contaminated diesel and the urea come out together after your tank is emptied, right there.

What remains from AdBlue won't flush out unaided, and so the whole system gets a full flush, which counts far more with urea than with petrol.

Clean diesel goes in after the fuel filter is flushed — or swapped, when it needs to be — and then your car is tested.

Engine not run? In that case count on roughly half an hour on site for most jobs.

The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.

Bleeding the fuel system with new diesel comes last.

You drive off as soon as our technicians have fired it up, and it makes no difference whether your car is on a drive in Grove Park or in a bay at the nearest station.

The check before we go is that it runs correctly on clean diesel.

No workshop is needed at any point, with the whole job done on the spot.

The insurer will want an engineer's report and your VAT invoice — each handed over once the job is done.

## About Grove Park and where it is

Grove Park is a suburban area in south east London, situated on the banks of the River Ravensbourne at an elevation of around 36 metres. Grove Park is characterized by its predominantly terraced housing and is located approximately 8.5 miles from central London. Grove Park borders several other suburban areas, including Chinbrook, Mottingham, and is not far from Plaistow. Grove Park has a population of around 8700 residents.

## AdBlue drains around Grove Park and across Greater London

Our vans that answer AdBlue jobs around Grove Park also cover the locations round it, Chinbrook, Mottingham and Plaistow among them, and most of Greater London beyond, across the SE postcode area.

Near a border, or somewhere tricky to explain? Asking beats guessing, so ring.

No moving is needed. In Grove Park, a residential suburb, a van that comes to you fits: your car is emptied where it stands, whether on a driveway, a residential street, a parking area or a filling station.

## What does AdBlue in a diesel tank cost to sort out around Grove Park?

Every job is different, and so no single quote is fair.

What shifts the price is, first of all, whether your engine has been running and for how long; then how much AdBlue went in; and then where the vehicle is and whether our van can reach it safely, which is easier on an open driveway than in a tight space behind Bannatyne's Health Club.

With that reason, each enquiry from Grove Park opens by asking the same trio — which fluid was put in, what quantity, if it ran — before any quote.

Their replies shrink a range right down to one number.

Quoted on the call before the van sets out, the job is paid for that day — card or phone, nothing in advance.

While our engineer is on the way, dig out your policy: many include misfuelling.

## Grove Park: still next to your car?

Then, touch nothing — that is the best move there is.

Motor off, keys out, ignition off.

Petrol in Diesel takes over the remainder, across Grove Park or wherever in Greater London, after you ring 0333 366 0103 to say it was AdBlue, about what quantity, and whether the engine ran.
