# AdBlue in the Diesel Tank in Dadford, and What to Do Next

What to do about AdBlue in a diesel tank depends on one thing more than any other: whether your engine has run since it got in.

If it hasn't, keep it that way, whether your car is in Dadford itself or out in Chackmore.

Ring 0333 366 0103 with your ignition and engine both off. In Dadford, such a case is typically emptied and flushed on the spot.

If it's run, stop as soon as it is safe then switch off.

Stage one stays the same, even though the job grows.

Find the scenario below that matches yours, wherever in Buckinghamshire it happened.

## AdBlue in a diesel on a Dadford forecourt

You are at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one.

Possibly you are at the AvantiGas, possibly at the Gulf, maybe somewhere else around Dadford.

In short: no better spot exists to spot it.

The AdBlue is in your tank and nowhere else. Nothing has sucked it in.

Do this: stay out of the driver's seat, however much the pump needs freeing.

Ring us from the forecourt after the car is in a bay — the attendants will help push it — and keep the receipt.

If it cannot be shifted, it can be emptied at the petrol pump: the equipment is explosion-proof and safe on a working forecourt.

## At home around Dadford with AdBlue in your diesel tank

On the dash, a reminder had been lit for days.

Picked up a bottle, tipped it in outside the house, recycled the empty — and only then checked the cap again, too late.

Houses just off High Street are hit as much as anywhere else.

What it means: if you haven't driven since, this is nearly as good as the forecourt.

Diesel and AdBlue stay apart: the AdBlue drops to the floor of the tank and stays there, however long the night.

What to do: leave the keys inside the house so no one moves the car in the morning. Then call.

Out in Wood Green or right here in Dadford, the drain happens on your drive.

The pumping kit runs quietly enough not to disturb the street at night.

## AdBlue in a diesel and already driving around Dadford?

You filled up, set off, and a mile or two later the engine began to run roughly, smoke, lose power or light up the dashboard.

Anywhere along Dadford Road or on the road towards Milton Keynes — under 15 miles away.

Put simply: the AdBlue has been pulled through the system.

Past the filter, through the pipework, and — the further the mileage — deeper into the high-pressure pump and every injector.

Each mile and each restart takes it further.

What to do: pull over where it is safe to do so then switch off.

Service stations further along can wait: on the M40, under 10 miles out of Dadford, use the first junction.

No test restarts: clearing isn't something AdBlue does.

Phone us and say how far you travelled.

## Hire, lease or company car with AdBlue in the wrong tank

You've only driven the car for days.

Your own motor either has no AdBlue or keeps it elsewhere, and so nothing warned you the AdBlue cap sits right beside the diesel.

Throughout Buckinghamshire, no one is immune.

The point: exactly as above, split by whether it ran, but with one added step.

Many hire and company contracts need the owner's approval before work.

Next: ring the hire company or the fleet manager first, and then us — sorting it before our arrival is faster.

If you're stranded in the car park at Wolverton, or by Dadford Village Hall, whilst you wait for an answer, leave the car off.

## Unsure about AdBlue in your diesel tank around Dadford?

"I think so" is sometimes the most honest answer there is.

What cap was taken off, you can't recall; meanwhile the bottle feels less than it ought to, and a whiff of ammonia hangs by your filler.

It might have been at a friend's driveway in Lillingstone Dayrell, or rushing outside St James and St John CofE Primary School at the school run.

The point: your motor is not harmed by a little AdBlue splashed around the outside.

If it is inside your diesel tank, though, it does.

Any AdBlue in the tank will be pulled in by starting your car, and the start would not settle which it is in any case.

What to do: treat it as if it went in. Do not start the vehicle.

Checking a tank that proves clean beats draining one once it has been run — so phone then describe to us what you noticed.

## The common ground in each Dadford AdBlue drain

No matter the situation, a single start applies.

We come to the vehicle, whether it's on a forecourt, a drive, the car park outside the pub in the village or a side street near Wolfe Obelisk, and ask three things: what was put in, about how much, and whether the motor has been run.

On the phone, before anything else, you are told the price, and those answers shape the work too.

AdBlue forms crystals and eats at certain metals in fuel systems, so it does not rinse out on its own; that's why the flush, after this drain, counts much more here than with petrol.

Next is your filter — flushed, or replaced when necessary — followed by fresh diesel, and a test of your car.

Never started? Then about half an hour on site is most jobs.

Firing it up comes last.

Before we head off, it is checked to confirm it runs smoothly on new diesel.

We do the entire job where the vehicle is, and permanent damage is very unusual when it has been noticed soon.

Payment comes on the day, never in advance. For your insurer, you get a VAT invoice plus a written report from the engineer.

Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.
