# What Now? AdBlue in the Diesel Tank in Garden City

One thing matters most when AdBlue is in a diesel tank, and it is if the motor has run afterwards.

Not started yet? Then keep the vehicle like that, wherever the vehicle is — Garden City or Yarnton.

Call 0333 366 0103 with your ignition and motor both off. In Garden City, such a case is typically drained and flushed where it stands.

If it has run, stop as soon as it is safe and switch off.

A larger job, then, but the same first step.

Anywhere across Oxfordshire it took place, one of the situations below fits yours.

## At the petrol pump around Garden City: AdBlue in a diesel

The cap you opened was the wrong one — and you only spot it as you are stood at the pump, bottle or nozzle in hand.

Be it Sainsbury's, BP or somewhere else around Garden City, the situation is identical.

Meaning? Finding out here is as good as it can be.

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

Your move: keep out of the car, however much the pump needs freeing.

Have the staff to lend a hand rolling it into a space, save the bottle, then phone us from there.

Our equipment is explosion-proof and fine on a live forecourt, so a vehicle that cannot be pushed away is cleared right at the pump.

## AdBlue in the diesel tank at home around Garden City

Several days had gone by with the dash light on.

A bottle bought at the shop, emptied in at the driveway — and it's just by the recycling that the cap got your eye.

Just off Hazel Crescent is not less likely from any other place.

The point: zero driving since leaves this almost as good to spotting it at the pump.

On the floor of the tank sits where AdBlue waits, because it won't mix with diesel — and a night going by makes no difference.

Put your keys indoors tonight — or someone may drive it away first thing — and phone us.

Gosford or Garden City: whichever your driveway is, that is where it gets cleared.

The pumps are quiet enough to use outside a house at night.

## Set off with AdBlue in a diesel around Garden City?

Filled up, drove away, and soon the motor was turning roughly, smoking, down on power, or lighting up your dash.

South Avenue, perhaps, or the route towards Oxford — a run of under 5 miles.

What it means: the fuel system has drawn the AdBlue in.

It has been through your filter and the lines and, the further you went, into your high-pressure pump and the fuel injectors.

It travels deeper with each mile driven and each restart.

Next: pick a sensible place, pull in, and turn your motor off.

Garden City sits under 10 miles from the M40; on it, come off at the next junction rather than pressing on to the services.

No test restarts: clearing itself isn't something AdBlue will do.

Phone, saying how far the vehicle went.

## AdBlue in the wrong tank of a hire, lease or company car

It's a car you have had for a week.

On your own vehicle, AdBlue is absent or somewhere else. On this one, the cap is just by the diesel inlet — a surprise to you.

Throughout Oxfordshire, no one is immune.

The upshot: just as above, split by whether it ran, only with one added step.

Work on the vehicle frequently requires the owner's approval under hire or fleet agreements.

Settling it before the van turn up is quicker, and so ring the hire company or your fleet manager, then us.

If you are stuck in the car park at Oxford Parkway, or by Saint John the Baptist Hall Church, whilst you wait for an answer, leave the car off.

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

Truthfully, the best answer may be that you think so.

Too light, that bottle; a trace of ammonia round your filler; no clear recollection of which cap. Look familiar?

The gates of St Thomas More Catholic Primary School, Kidlington in a rush, say, or a friend's drive out in Cutteslowe.

The upshot: the motor isn't hurt by some AdBlue splashed on the outside.

AdBlue inside the diesel tank does.

Starting the vehicle will not tell you which, and if there is AdBlue in that tank it would pull it in.

Next: assume it went in, then leave the engine off.

Tell us what you noticed on your phone. A clean tank looked at is a better outcome than an already-run one emptied.

## Each AdBlue drain in Garden City shares these steps

The job begins the same way, whichever your situation.

Three things come once our engineers reach your car — at a filling station, a drive, a street beside Rosie the Elephant or the car park outside The Turnpike: the liquid, the amount, and whether the motor has run.

Replies shape the work; the price follows on the call whilst no one has set off yet.

A thorough flush follows the drain. With petrol it's routine; with AdBlue it's essential, because deposits form and some metals are attacked, and neither rinses away unaided.

Fresh diesel is put in once the filter is cleaned or replaced, and your car is then tested.

Never started? In that case about half an hour on site covers most jobs.

The last step is starting it.

Our check that it runs correctly on new diesel comes before we head off.

The entire job is done where the car is, and if it is caught early, lasting damage is very unusual.

Payment is that day, never in advance. For the insurer, you get a VAT invoice and a report from the engineer.

Plenty of policies include misfuelling, and so check yours while the van travels.
