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

Stop reading for a moment if your diesel tank already holds AdBlue in it: ignition off, engine off, then ring 0333 366 0103. Caught before your engine runs, it is generally a drain and a thorough flush, done where the car is in Copley Hill. The rest of this page explains why it happens and how to make sure it doesn't — useful if you are reading before it has happened.

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

Not one liquid but two: that's how many modern diesels near Copley Hill and Birstall carry, with diesel for your engine. The exhaust, not your motor, is where AdBlue goes: dosed into the gas to fresh it, from a separate tank.

Every tank has a filler of its own. On a lot of vehicles 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 topped up at the petrol pump all the time. A driver who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and much less regularly. It is in the gap that the error happens.

Copley Hill: how AdBlue in the diesel tank occurs

Three things tend to line up, and carelessness is seldom one of them.

Haste comes from the warning. Your car warns you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off Sandal Way, or heading home in the car park outside Horse and Jockey.

Next, your hand goes for the cap it would have used on the old vehicle — since a rental car, a new motor or a company car puts the fillers somewhere your last one did not.

No part stops the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's seconds, be it in Brownhill End or bang in the centre of Copley Hill.

How to tell the AdBlue filler from the diesel one

A few seconds is all the checks take — so check them before you pour anything, on a drive in Brookroyd or a forecourt around Copley Hill.

  • Read the cap rather than going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel caps normally are not.
  • On many cars, size tells: AdBlue gets the smaller filler neck.
  • Open the flap and look for a label — many cars show which goes in which filler just there.
  • Cannot find it beside your diesel filler? In that case look beneath the bonnet or in the boot — the owner's manual says which.
  • Whoever had it before knows. Check as you collect a hire car or fleet car — at Batley's car park, perhaps — rather than when the light appears.

AdBlue top-ups that never reach your diesel tank

For the day the warning comes on — wherever it is around West Yorkshire — a routine to follow.

  • Park then switch off. Not on a slope, not with your motor running, and not in a rush on the side of Sycamore Way.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Silly, yes, yet it does the trick.
  • Leave your diesel cap on. If both sit under one flap, check your 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 car: close the cap, check once more, and make sure the diesel cap was never opened.

If at step two or three you find you have already poured into the diesel side, stop there. Never go on to step five.

AdBlue in the diesel tank already, in Copley Hill?

The short order of things, starting with not starting your motor. The fuel pump runs on plenty of diesels as soon as the ignition goes on — so keep it off. Diluting it with more diesel won't work, because AdBlue settles to the bottom rather than blending — and that is where the fuel is pulled from.

If you're at a forecourt, whether it's the Texaco or the another forecourt nearby, ask the attendants to help push your car clear of the petrol pump. Leave it where it is if you're on your own drive in Copley Hill.

Stop as soon as it is safe and switch off, if your engine has already run. The next junction means where to leave when you're on the M62, under a mile from Copley Hill. About how far did it go? Crossing Copley Hill is smaller work than a trip of under 10 miles towards Bradford, and so say.

What occurs when our technicians turn up in Copley Hill

We come to your car wherever it has stopped, whether that is outside Birstall Primary Academy, near Birstall Methodist Church or on your own driveway. The answers determine this work and the price, and so our technicians ask what went in, about how much, and if it's run. On the call itself, you hear our price — ahead of dispatch.

The system is then cleaned thoroughly, once your tank is drained. More than with petrol, it matters with AdBlue: the crystals build up, some metals are attacked, and none of that washes away unaided, no matter how long it is left. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Before we go, we fire it up and confirm that it's running properly.

Unstarted cars mostly mean a half-hour job after arrival. The kit is safe on a live filling station, and hushed enough for a driveway after dark. Nothing in advance; you settle up that day. At the end, the VAT invoice and a report from the engineer are handed to you for your insurer. It is worth looking at your policy while we travel to you: misfuelling cover is included with plenty of policies.
