# AdBlue in a Diesel Tank in Salcombe: How It Occurs and How to Stop It

Leave your motor and ignition off then call 0333 366 0103 now — reading can wait when AdBlue is already in the diesel tank.

Caught before the engine runs, it is normally a drain and a thorough flush, done where your car is in Salcombe.

If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not.

## Two fillers, two tanks: AdBlue in a diesel vehicle

No single fluid but two: that's what many newer diesels near Salcombe and Higher Batson run, with diesel feeding your motor.

AdBlue's own tank holds it, and from there it is sent to the exhaust, and there spraying cleans the fumes.

There is a filler for each tank.

On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet.

The diesel side is filled at the petrol pump all the time.

Someone who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and far less often.

That gap is where the mistake lives.

## How AdBlue in the diesel tank occurs in Salcombe

Carelessness rarely explains it. Instead is three things lining up together.

On a drive off Robinsons Row before work, or in the car park outside The Victoria Inn on the way home: that's where the rushed top-up happens. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and once it is gone, limp mode follows.

Then the car is new. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and your hand hits for the cap it would have used on the old one.

A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. And so the tip, after begun, keeps on.

The same few seconds settle it, in the middle of Salcombe or out in Batson.

## How to tell the AdBlue filler from the diesel one

Be it a Salcombe forecourt or a driveway out in Rickham, spend a couple of seconds on these before anything goes in.

- Colour and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position.

- Many cars give AdBlue the smaller neck of the two.

- Lift the flap and look for a label — plenty of vehicles show which goes in each inlet just there.

- The handbook shows which it lives if your filler is not next to your diesel cap: your boot, or under the bonnet.

- Collecting a hire or company car, say at the car park outside the nearest station? Ask whoever drove the car last before you set off, rather than once the light goes on.

## AdBlue top-ups that never reach your diesel tank

The day the light comes on, wherever across Devon, follow this routine.

- Turn off after you park — level ground, engine off, and not rushed by Baptist Lane at the roadside.

- Locate the AdBlue filler, read the cap, and say the word "AdBlue" out loud as you unscrew it. It seems silly. It does the trick.

- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on.

- Slowly does it, through the bottle's own spout, until it is full or the bottle is empty.

- Before starting your car, close the cap and look a second time that the diesel cap never opened off.

Discover at the second or third step that the bottle went in the diesel filler? That's where you stop.

Step five stays off limits.

## Already put AdBlue in your diesel tank in Salcombe?

Short order, then. Top of it: the engine stays off.

The fuel pump starts on plenty of diesels as soon as your ignition is switched on — and so keep it off.

Diluting it with extra diesel fails, since AdBlue settles to the base rather than blending — and that's where your fuel is pulled from.

At a forecourt — Gulf, Asda Express or another — the attendants will usually help push the car away, if you ask.

At home in Salcombe? So your car stays where it is.

Stop as soon as it is safe then switch off, if your engine has already run.

Salcombe lies under 50 miles from the M5; there, take the first exit.

Roughly how far did it go? Hopping across Salcombe is less work than a run of under 25 miles to Plymouth, so tell us.

## When our engineers get there around Salcombe, what happens?

Outside Salcombe Church of England Primary School, close to Salcombe Maritime Museum or on your own driveway: wherever the car has stopped, our engineers come to it.

Those answers settle this work and the quote, so we ask what got in, roughly how much, and if it's run.

On the phone call itself, you are told our price — ahead of anything else.

Then your tank is drained and your system flushed thoroughly.

With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own.

Filter cleaned or, if needed, replaced; fresh diesel in; and then a check of your car.

Then our technicians fire it up and check it runs properly before leaving.

With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which your motor hasn't run need roughly half an hour after our technicians are there.

Payment is on the day, not upfront, and you are given the documents an insurer wants: an engineer report and a VAT invoice.

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

Awkward to pin down, like the back of Salcombe War Memorial? By a border? Asking beats assuming, so ring.
