Pyle: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?

Leave the motor and ignition off then phone 0333 366 0103 now — the rest can wait if AdBlue is already in the diesel tank. A drain and a full flush, carried out just where your vehicle sits around Pyle, is usually all it needs when caught before the motor runs. Here before the event? In that case the rest covers why it comes about and what to prevent it happening at all.

Why does AdBlue in a diesel motor need its own filler?

Plenty of newer diesels around South Cornelly, like those in Pyle, carry on two fluids; your motor takes only your diesel. Your exhaust, not your engine, is where AdBlue goes: dosed into the gas to fresh them, from its own tank.

Different tanks, separate fillers. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. The diesel side is filled at the pump all the time. A driver who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less frequently. The mistake lives in that gap.

Pyle: how AdBlue in the diesel tank happens

It's rarely carelessness. Three things tend to line up.

First, the warning. Low AdBlue brings a message from your car, and running dry means limp mode — so a rushed top-up, maybe before work off Ffald Road, or outside Ye Olde Wine House on the way home after work.

Next, the hand goes for the cap it would have used on the old motor — because a rental car, a new motor or a company car places the fillers somewhere your last one didn't.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. North Cornelly or the heart of Pyle: it takes the same few seconds either way.

How to tell the AdBlue filler from the diesel one

Whether a Pyle forecourt or a driveway over in Pen-y-bryn, spend a few seconds over these before any goes in.

  • Colour and marking: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not its position.
  • On many cars, the size gives it away: AdBlue gets the smaller filler neck.
  • A label inside your fuel flap often shows which fuel goes where, on plenty of cars. Look for it.
  • The handbook says where it lives when your filler is not next to the diesel cap: your boot, or under the bonnet.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at the nearest station.

Keeping AdBlue out of your diesel tank when you top up

A routine for the day the light comes on, wherever around Bridgend that is.

  • Not in a rush on the side of Marlas Close, not on a slope, not with the motor running: park then switch off properly.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
  • Only after that, start the vehicle: close the cap, check a second time, and make sure your diesel cap was never opened.

Find at step two or three that it has already gone into the diesel side? So stop right there. Stage five is off limits.

Pyle: already put AdBlue in the diesel tank?

Brief order, then. First: the engine remains off. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where your fuel is drawn from.

The attendants at Asda, Esso or another forecourt will normally help to push the car clear if you ask. Leave it where it is if you are on your own drive in Pyle.

When your motor has been run by now, pull over somewhere safe then switch it off. Pyle lies under a mile from the M4; there, use the first exit. Roughly how far did it go? Hopping across Pyle is smaller work than a run of under 15 miles towards Swansea, and so tell us.

What occurs when our engineers arrive in Pyle

The van comes to the vehicle wherever it stopped — your own drive, near Church of St James, or by the local primary school. Which liquid went in, the amount, and whether it ran: we ask because the replies set the work and quote. You get that quote by phone, before anybody sets off.

Then the tank is cleared and the system cleaned thoroughly. More than with petrol, it matters here: the crystals build up, certain metals corrode, and none of it clears away on its own, however long it is left. After the fuel filter is cleaned — or replaced, if needed — fresh diesel goes in, and then your car is tested. Next our engineers fire it up and confirm it runs properly before leaving.

Most jobs are finished in about half an hour after our engineers arrive, provided the engine hasn't run — and the pumps our engineers use are safe on a busy forecourt and quiet at night outside a house. Payment happens on the day, not upfront, and you receive the paperwork an insurer asks for: an engineer report and a VAT invoice. While we travel, take a look at your policy; plenty include cover for misfuelling.

AdBlue drains about Pyle, and Bridgend beyond

As a coastal village, Pyle has the same vans as nearby places — Kenfig Hill, Coedhirwaun — right through CF postcodes and the surrounding area beyond. A postcode starting CF33 6 gets our van to you fastest.

The car remains put. Wherever it sits — beside Pyle Library, in a layby en route to Croft Coch Playing Fields, on a drive — that is where it is cleared. Guessing doesn't help behind Heathbridge Miners' Square, on a border, or somewhere hard to describe; phone and ask.

Pyle people: the short version

Tip nothing until you have read the cap. Petrol in Diesel drains it where it stands, anywhere in Bridgend, if AdBlue has gone in your diesel tank anyway — and so leave it off then ring 0333 366 0103.
