# AdBlue in the Diesel Tank in Warren Heath? Keep It Switched Off

AdBlue in your diesel tank? Then keep your engine off — and the ignition too.

Urea dissolved in water is all AdBlue is.

It does not burn, it doesn't mix with diesel, and the damage it does starts when the fuel system draws it in.

If the motor hasn't run yet, AdBlue in a diesel tank is normally drained and carefully purged where the vehicle sits in Warren Heath.

Call 0333 366 0103 before you do anything else.

## Warren Heath, AdBlue in the diesel tank: what to do right away

Do:

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

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

- The empty bottle or the receipt shows us the fluid and the quantity, and so do not throw it away.

- Ring right where you are. Say a IP3 8 postcode or the nearest street sign, and nobody has to hunt for you.

Don't:

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

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

- AdBlue doesn't dilute in diesel — it separates out — so adding extra diesel will not thin it.

- Even a short way down Beechwood Drive is too far to drive it.

- Do not try to drain the car yourself at the roadside.

The attendants on duty at any Warren Heath filling station — the Sainsbury's among them — will usually help pushing it clear if you ask.

If you're on your own drive, leave the car precisely where it is.

## What does AdBlue do in a diesel tank?

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

It goes into its own tank and is sprayed into your exhaust gas to clean it.

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

Fuel blends; AdBlue, once poured in, will not. Its behaviour is not at all like diesel's.

It drops, since it is heavier than diesel, and settles low where the pickup draws its supply from.

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

From there it does two kinds of harm.

Crystals and corrosion. As the water dries, it strands urea that hardens in filters and narrow channels; and, because it eats at some metals, every part it reaches keeps suffering for as long as it stays in there.

A motor left standing around Warren Heath with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't.

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

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

Petrol put into a diesel on East of England Co-op's forecourt leaves your fuel watery — that's the whole problem.

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

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

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

Deposits and corrosion stay after the following tankful, and AdBlue separates again from the diesel, and so thinning it won't work. Hence the flush matters more, and trying the engine "to see" does more harm here than nearly any other mistake — in Rose Hill or the centre of Warren Heath alike.

The same good news holds as with petrol.

If the motor hasn't run, the AdBlue is still in your tank, and your tank is the simplest part of a fuel system to clear, wherever across Suffolk your car is sitting.

## How AdBlue ends up in a diesel tank around Warren Heath

No one means to do it. The AdBlue filler on many cars rests 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 driveway, not at the pump.

It tends to occur in a few familiar ways.

A warning light comes on during the school run, and the top-up happens in a hurry outside Ravenswood Community Primary School.

In the evening, a container goes in on a driveway close to Purdis Farm Lane.

Else, in dim light by The Thrasher, the vehicle is topped up by someone using that flap the first time.

The least familiar vehicles get it the most — hire cars, brand-new cars, company ones, and the other motor of a home with both fuels.

Same mistake, an identical first step — keep it off — anywhere you happen to be in Warren Heath or the rest of Suffolk.

## Already started the motor with AdBlue in your diesel tank in Warren Heath?

The AdBlue has left the tank, then.

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

Lumpy running, smoke, lost power, dashboard warnings or stalling: any may show up, perhaps part way across Warren Heath or coming back from Jacobsen Golf Course.

Once you safely can, stop then switch everything off — with no restarting to see.

More of that is pulled through with each start.

If you were on the M11, under 50 miles from Warren Heath, come off at the next exit and stop somewhere safe instead of pressing on.

Mileage matters: each mile pushes the AdBlue further in, and so driving for Colchester, under 25 miles away, gives a much bigger job than hopping across Warren Heath to the car park by Suffolk Trinity.

Tell us about how far it had come.

Our engineers do all of the cleaning where your car has ended up, and once your engine has run there is more of it.

Very rarely does it leave long-term damage when it is spotted soon.

## What does an AdBlue drain on a diesel involve around Warren Heath?

A street beside Man and Ball, a driveway, a lay-by or a forecourt: wherever the vehicle has stopped around Warren Heath, our engineers travel to it.

Three replies shape the job, so before anything else we ask which fluid went in, roughly what quantity, plus if your engine has run.

The contaminated diesel and the urea leave together after your tank is emptied, on the spot.

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

After that, your filter: cleaned, or changed if it must be. Then clean diesel, then a check of the vehicle.

The majority of these jobs are a half-hour visit once our technicians turn up, provided the engine hasn't run.

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

The last step is to prime the fuel system on fresh diesel.

You set off as soon as our engineers have fired it up, and it makes no difference whether your car is on a driveway in Warren Heath or in a space at Derby Road.

Our engineers confirm it runs smoothly on new diesel before leaving.

Because the job is done in its entirety where your car is, a workshop never comes into it.

You receive a VAT invoice and an engineer report later, which is what insurers ask for.

## AdBlue drains around Warren Heath and across Suffolk

If you're close to a boundary, or somewhere hard to describe, ring and ask instead of guessing.

Warren Heath is a coastal area, and an on-site drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it stands, so it never needs to be shifted to us.

## What AdBlue in a diesel tank costs to put right around Warren Heath

Each job differs, so no single quote is honest.

Whether your engine has been running, and for how long, comes first in what changes the cost. How much AdBlue went in comes next, and then the location of the vehicle, since an open drive is easier for our van to get to safely than a tight space behind John Lewis.

What was put in, how much, plus whether the engine ran: every Warren Heath call begins by asking exactly those, before a figure, never after.

Those replies turn a range into a straight quote.

Quoted on the call before the van sets out, it is settled that day — card or phone, no deposit.

Look at your policy whilst we're on the way: many carry misfuelling cover.

## In Warren Heath and still alongside your car?

In that case, do nothing — that's the most helpful step there is.

Ignition off, motor off, keys out.

Call 0333 366 0103: AdBlue, roughly how much, and if it ran is everything our technicians need. Petrol in Diesel takes over the remainder across Suffolk, Warren Heath included.
