# AdBlue in a Diesel Tank in Market Brough: Why It Happens and How to Avoid It

Keep your motor and ignition off then ring 0333 366 0103 first — the rest can wait if AdBlue is already in your diesel tank.

Caught before the engine runs, it's normally a drain and a thorough flush, done where the car is in Market Brough.

The remainder of this page covers why it occurs and how to make sure it does not — handy if you are reading ahead of time.

## AdBlue in a diesel car: two tanks, two fillers

Not one liquid but two: that is what many newer diesels around Market Brough and Brough Sowerby carry, with diesel for your engine.

Kept in a tank of its own, AdBlue is sprayed into your exhaust gas and cleans it.

Each tank has its own filler.

Under one flap, side by side: that is the arrangement on many cars. Elsewhere, AdBlue's filler is beneath the bonnet or in your boot instead.

Diesel gets filled at each filling station visit, again and again.

Rarely filled, AdBlue normally goes in from a bottle, poured by a driver who must stop and think what cap to use.

The slip lives in that gap.

## How AdBlue in your diesel tank takes place around Market Brough

Seldom is it carelessness: usually three things line up.

First, the warning. Low AdBlue triggers a warning from your car, and letting it run out means limp mode — so a hurried top-up, perhaps before work off Helbeck Road, or outside the pub in the village on the way home after work.

The old car's filler is where the hand reaches — but a rental car, a new car or a company car puts the fillers elsewhere. That is the second thing: a strange vehicle.

Third, the spout fits: a diesel filler or AdBlue filler, it slides in just as readily, and after the tip starts, no part halts it.

Brough or the middle of Market Brough: it takes the same few seconds in both.

## Which filler is for AdBlue, and which for diesel?

Before you tip anything, whether on a drive in Langrigg or a forecourt in Market Brough, check these. They take a few seconds.

- Check the cap instead of going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel caps normally aren't.

- Plenty of vehicles give AdBlue the smaller neck of the two.

- Lift the flap and check for a label — plenty of motors mark which belongs in each inlet just there.

- The handbook. If the filler is not by the diesel cap, it's in your boot or under the bonnet, and the handbook says which.

- The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Kirkby Stephen, ask before you leave, not when the light comes on.

## Keeping AdBlue out of your diesel tank when you top up

For the day the light comes on — anywhere you are in Cumbria — a simple routine to follow.

- Switch off once parked — flat ground, motor stopped, and not in a rush beside Swan Avenue at the roadside.

- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, perhaps, yet it does the trick.

- The diesel cap remains on. When the two share a flap, make sure it's shut before lifting the bottle.

- Gently does it, through the bottle's own spout, until it is full or the bottle runs out.

- Shut the cap, and check again — confirm the diesel cap remained closed the whole time. After that, start the vehicle.

Stop there if you find, at step two or three, that you have already poured into your diesel side.

Do not go on to stage five.

## AdBlue in your diesel tank already, in Market Brough?

Short order, then. First: your engine remains unstarted.

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

Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where your fuel is sucked from.

If you're at a forecourt, whether it's the Shell or the Total Energies, ask the attendants to help roll your car away from the petrol pump.

If you're on your own drive around Market Brough, leave the vehicle where it is.

Already run? Pull over when it's sensible, then switch off.

The next junction is where to leave when you are on the M6, under 15 miles from Market Brough.

Tell us roughly how far it went: a run towards Durham, under 50 miles away, is a bigger job than a short hop across Market Brough.

## Our arrival in Market Brough, and what happens next

Anywhere the car has stopped, be it outside Brough Community Primary School, beside Brough Pinfold or on your own drive, our van comes to it.

Both the work and our quote rest on three answers — which liquid, which quantity, and whether it's run — so our engineers ask.

The price is given on the call, ahead of any van leaving.

Next: draining, then a full flush of the whole system.

AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why the flush counts more with AdBlue than with petrol.

The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested.

The motor is started next and tested to be sure it runs correctly, all before we head off.

Most jobs are finished in about half an hour once our engineers get there, as long as your engine has not run — and the pumps our engineers use are fine on a busy forecourt yet quiet at night outside a house.

The insurer usually wants the engineer's report and your VAT invoice, and you get both once this job is done. Payment is on the day, with no money upfront.

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

Moving the vehicle is not needed.

A driveway, a lay-by on the way to Brogden's Plantation, a side street close to Brough Castle: we drain it where it stands.

Ring and ask instead of assuming if you are near a border, or somewhere hard to explain, like the back of Verterae.
