AdBlue in a diesel motor, and its separate tank

Many modern diesels in Low Baildon, like those in Tong Park, run on two liquids; the engine gets just the diesel. Kept in a tank of its own, AdBlue is sprayed into your exhaust stream to clean it.

Every tank comes with one filler of its own. Under one flap, next to each other: that's the layout on many vehicles. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. Diesel goes in at every filling station visit, week in, week out. Someone who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and much less commonly. It is in that gap that the slip lives.

Tong Park: how AdBlue in your diesel tank happens

Three things tend to come together, and carelessness is seldom one of them.

To start with, the warning. Low AdBlue brings a message from your car, and running dry means limp mode — so a rushed top-up, perhaps before work off Hallside Close, perhaps outside The Old Barn Esholt on the way home after work.

Then your car is strange. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand gets to for the cap it would have used on the old one.

Lastly, the spout fits: a diesel filler or AdBlue one, it slides in just as easily, and once the pour starts, no part halts it. Whether it happens in Park or the middle of Tong Park, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Tong Park

Telling the AdBlue filler from your diesel filler

A few seconds is all these take — so check them before you tip anything, on a driveway in Church Hill or a forecourt around Tong Park.

  • Where it sits can mislead; the cap does not. AdBlue caps are often blue or bear the word "AdBlue" — diesel caps usually do not.
  • On many vehicles, size gives it away: AdBlue has the smaller filler neck.
  • A label inside your fuel flap often shows which fuel goes where, on plenty of cars. Look for it.
  • Cannot find it beside the diesel inlet? Then check below the bonnet or inside the boot — the owner's manual says where.
  • Collecting a hire or company car, say at the car park at Baildon? Check with whoever drove the car last before leaving, not when the light comes on.

AdBlue top-ups that never reach the diesel tank

Anywhere in West Yorkshire the light comes on, here is a routine for that day.

  • Switch off once parked — flat ground, motor stopped, and not in a rush beside Broadacre Way on the verge.
  • Locate the AdBlue filler, check the cap, and speak the name "AdBlue" aloud while unscrewing it. It sounds silly. It works.
  • The diesel cap remains on. Where both share a flap, make sure it is shut before lifting the bottle.
  • Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty.
  • Only then, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened.

Discover at the second or third stage that AdBlue went into the diesel filler? That is where you stop. Don't go on to stage five.

AdBlue in your diesel tank already, around Tong Park?

Do not start the engine: that is how the short order of things begins. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. Filling up with diesel won't thin it: rather than mixing, AdBlue sinks to the bottom of your tank, right where the fuel is drawn from.

If you're at a forecourt, whether it's the Esso or the UK Petroleum, ask the staff to help push the vehicle clear of the petrol pump. On your own drive in Tong Park? So the vehicle stays put.

Stop as soon as it is safe and switch off, if your engine has already run. Tong Park sits under 10 miles from the M606; on it, take the first exit. Tell us about how far it went: a run towards Bradford, under 5 miles away, is a bigger job than a short hop across Tong Park.

When our engineers turn up around Tong Park, what occurs?

Outside Baildon Church of England Primary School, near Tong Park Memorial or on your own drive: wherever the vehicle has stopped, our engineers come to it. We ask what got in, roughly how much, and if it's run, because the replies decide this work and the quote. You get that price by phone, before anyone heads out.

After that: draining, then a thorough flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that matters more with AdBlue than with petrol. A test comes last: before that, fresh diesel goes in, and the fuel filter is flushed or replaced if necessary. We do not go until it has been fired up and is running properly.

If the motor hasn't run, most jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark. Paying is on the day, not upfront, and you are given the documents an insurer asks for: an engineer's report and a VAT invoice. Wrong-fuel cover is part of plenty of insurance policies — and so make use of the wait to check yours.
