Preventing AdBlue in a Diesel Tank in Great Wyrley: Why It Happens

Pause reading for a moment when your diesel tank already has AdBlue in it: ignition off, motor off, and phone 0333 366 0103. Caught before the motor runs, it is normally a drain and a thorough flush, done where the vehicle is around Great Wyrley. Here before the event? In that case the rest covers how it comes about and what to prevent it happening at all.

AdBlue in a diesel car: two tanks, two fillers

No single fluid but two: that is what many modern diesels near Great Wyrley and Cheslyn Hay carry, with diesel feeding your motor. AdBlue's own tank holds it, and from there it goes to the exhaust, and there spraying cleans the fumes.

Each tank has its own filler. Plenty of vehicles share a single flap for the two, while some move the AdBlue filler to your boot or under the bonnet. Filling your diesel side at the pump goes on constantly. A driver who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and much less regularly. That gap is where the error lives.

How AdBlue in the diesel tank takes place around Great Wyrley

Carelessness rarely explains it. What does is three things lining up together.

The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Johns Lane before work, or in the car park outside The Star Inn on the way home.

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

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

Flushing a diesel fuel system after AdBlue, Great Wyrley

How to tell the AdBlue filler from the diesel one

Whether a Great Wyrley forecourt or a driveway over in Leacroft, take a couple of seconds on these before anything is poured in.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap usually isn't. Read it instead of going by where it sits.
  • Look at the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one.
  • Lift the flap and check for a label — plenty of motors show which belongs in which filler just there.
  • The handbook shows where it lives if your filler isn't next to the diesel cap: your boot, or under the bonnet.
  • Collecting a hire or company car, perhaps at the car park outside Landywood? Check with whoever drove the car last before you set off, rather than when the light goes on.

Keeping AdBlue out of your diesel tank when you top up

A routine for the day the light comes on, wherever across Staffordshire that is.

  • Turn off after you park — level ground, motor stopped, and not rushed beside Martin Grove at the roadside.
  • Silly as it sounds, saying "AdBlue" aloud while you unscrew the cap works — once you've found the filler and read the cap.
  • The diesel cap remains on. When the two share a flap, make sure it is closed before lifting the bottle.
  • Stop once the tank fills or the bottle runs dry; before that, tip gently using the built-in spout.
  • Only then, start your car: close the cap, check again, and make sure your diesel cap was never opened.

Stop there if you find, at step two or three, that you've already poured into the diesel side. Don't go on to step five.

Already put AdBlue in your diesel tank around Great Wyrley?

Do not start your engine: that is where the short order of things starts. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with more diesel won't work, because AdBlue sinks to the base rather than mixing — and that's where the fuel is pulled from.

Ask the staff to help roll your car away from the petrol pump if you're at a forecourt — the Esso, the Sainsbury's or somewhere else. Your own drive in Great Wyrley is where it stays.

Stop as soon as it is safe and switch off, if your engine has already run. On the M6 Toll, under a mile from Great Wyrley, that means the next junction. A short hop across Great Wyrley is a smaller job than a run towards Wolverhampton, under 10 miles away, and so tell us roughly how far it went.

Great Wyrley: what takes place when our engineers arrive

By Moat Hall Primary Academy, close to St Andrew or on your own drive: wherever your car has stopped, our technicians come to it. The answers settle the work and our price, so our engineers ask what got in, about how much, and whether it's run. On the phone call itself, you are told our price — ahead of anything else.

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 the flush counts more with AdBlue than with petrol. The filter flushed or, if needed, replaced; fresh diesel in; and then a test of the car. Before we go, our technicians start the car and check that it's running smoothly.

Most jobs are finished in about half an hour once our technicians arrive, as long as the engine hasn't run — and the pumps we use are fine on a live forecourt and quiet at night beside a house. The insurer usually wants an engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.
