# AdBlue in the Diesel Tank in Bushey: What Now?

Has the motor run since the AdBlue was put in? That single question settles nearly everything else from here.

Anywhere your car is — The Rookery, Bushey — never start an engine that hasn't been started yet.

Leave the motor and your ignition off and phone 0333 366 0103; it is generally a drain and a thorough flush, done where the car is in Bushey.

When your engine has been run, stop safely first, then turn it off.

A larger job, then, but the identical first move.

Further down: the situations our technicians see, anywhere across Hertfordshire. Pick the one that fits.

## On a Bushey forecourt with AdBlue in a diesel

Only now, nozzle yet in your hand, you realise that the cap you opened was the wrong one, there at the petrol pump.

It might be the Tesco, or the Costco, or a different station around Bushey.

What it means: this is the ideal place to find out.

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

What to do: don't get back in and fire it up to clear the pump.

Have the staff to help pushing it to a bay, save the bottle, then ring us right there.

If it can't be moved, it can be drained at the pump: the equipment is explosion-proof and fine on a busy forecourt.

## AdBlue in your diesel tank at home around Bushey

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

Only by the recycling, the empty bottle in your hand, did you glance back at the cap you'd used at the drive.

Homes just off Park Road are hit as much as anywhere else.

Meaning? Provided the car has not been driven since, it's second to the pump case.

At the floor of your tank is where AdBlue stays, because it won't mix with diesel — and a night going by changes nothing of the difference.

Put your keys in the house overnight — or someone may drive it away first thing — then call us.

Our engineers drain it on your driveway, whether that's around Bushey or out in Watford Heath.

Night-time drains outside a house are fine: the pumps are quiet.

## Bushey: drove off with AdBlue in a diesel?

A short way after topping up, the engine started playing up: rough running, smoke, less power, lights on your dash.

Anywhere on High Street or on the road to St Albans — under 10 miles away.

In short: the AdBlue has been pulled into the fuel system.

Past your filter, along the lines, and — the more the mileage — deeper into the high-pressure pump and each injector.

More miles, more restarts: further it travels.

Next: pick a sensible spot, stop, then turn the motor off.

Exit by the first junction — not the services beyond — if you are on the M1, under 3 miles from Bushey.

It won't have cleared, so there's no point restarting to check.

Tell us know the mileage driven when you call.

## A hire or company car with AdBlue in the wrong tank?

You have just driven the vehicle for days.

Your own vehicle either does without AdBlue or keeps it somewhere different, and so nothing told you the AdBlue inlet was just next to your diesel.

Across Hertfordshire, no one is safe from it.

Meaning? Whatever case above counts too — run or unrun — plus one extra step.

The owner frequently needs to sign off the work, under plenty of hire and company agreements.

Sorting it before the van arrives is faster, and so ring the hire company or your fleet manager, and then us.

Stuck by Bushey Museum or outside the nearest station until someone answers, your vehicle stays turned off the whole time.

## Not sure it was AdBlue in your diesel tank, Bushey?

Honestly, the only answer might be that you think it did.

Lighter, that bottle; a hint of ammonia round your filler; a hazy memory of which cap. Look familiar?

The gates of Sacred Heart Catholic Primary School and Nursery in a hurry, perhaps, or someone's drive out in Caldecote Hill.

Meaning? Spills outside the filler don't reach your engine at all.

AdBlue inside the diesel tank does.

You cannot tell which by turning the ignition, and doing so would pull in any AdBlue that is in that tank.

Your move: behave as if it got in, and never start your motor.

Ring us and describe what you saw; we would rather check a tank that turns out free of AdBlue than drain one that has already been run.

## The common ground in every Bushey AdBlue drain

The job begins identically, whichever the case.

Three things come once our engineers arrive — at a forecourt, a drive, a street by St James' or the car park outside The Swan: the liquid, the quantity, and whether the motor has been started.

Over the phone, before dispatch, you are told our price, and those answers decide the work too.

A thorough flush comes after the drain. With petrol it's routine; with AdBlue it's essential, since deposits build up and certain metals are attacked, and none of it rinses out unaided.

Clean diesel goes in once the fuel filter is flushed or replaced, and your car is finally checked.

Where your engine has not run, allow roughly half an hour once we arrive, in most cases.

We fire it up last.

Our technicians confirm it runs correctly on new diesel before we leave.

When it is spotted early, the vehicle very seldom has long-term damage, and the entire job takes place where it is.

For your insurer: the engineer's report and the VAT invoice. For you: payment that day, no money upfront.

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