Avoiding AdBlue in a Diesel Tank in Hall Green: Why It Occurs

Pause reading a minute when the diesel tank already has AdBlue in it: ignition off, motor off, then call 0333 366 0103. A drain plus a full flush, carried out right where your vehicle sits in Hall Green, is usually what it takes if caught before the engine runs. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't.

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

Many newer diesels around Bradley, like those in Hall Green, run on two liquids; the motor takes only your diesel. Stored in a tank of its own, AdBlue is sprayed into your exhaust stream and cleans it.

Every tank comes with one filler of its own. Under one flap, side by side: that is the arrangement on many motors. On others, AdBlue's filler sits beneath the bonnet or in your boot instead. At the pump, your diesel side gets filled constantly. Seldom filled, AdBlue usually comes out of a bottle, poured by someone who has to stop and think what cap to use. The slip lives in that gap.

How AdBlue in the diesel tank happens in Hall Green

Seldom is it carelessness: usually three things line up.

First, the warning. Low AdBlue brings a warning from your car, and running dry means limp mode — hence a hurried top-up, maybe before work off Wainwright Close, or at The White House 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 did not, and your hand reaches for the cap it would have used on the old one.

Third, the bottle fits: diesel filler or AdBlue one, it slides in as easily, and after the tip starts, nothing stops it. It takes a few seconds, be it out in Batmans Hill or bang in the heart of Hall Green.

How to tell the AdBlue filler from the diesel one

A few seconds is all the checks take — so run through them before you tip anything, on a drive in Highfields or a forecourt in Hall Green.

  • Where it sits misleads; the cap doesn't. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel caps usually don't.
  • Look at the size: the smaller filler neck is, on plenty of cars, the AdBlue one.
  • The flap. Look inside the fuel flap for a label. Many motors say there which fuel goes where.
  • Can't see it beside your diesel inlet? In that case check beneath the bonnet or inside the boot — the handbook will say where.
  • Whoever had it before will know. Check as you collect a rental or fleet car — at Coseley's car park, say — not when the light appears.

AdBlue top-ups that never reach the diesel tank

For the day the warning appears — anywhere you are across West Midlands — a routine to follow.

  • Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Brierley Lane.
  • Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Daft, perhaps, yet it works.
  • Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Gently is best, through the bottle's own spout, until it's full or the bottle runs out.
  • Before you start your car, close the cap and look a second time that the diesel cap was never came off.

Find at the second or third stage that the bottle went in the diesel filler? That's where you stop. Step five is off limits.

AdBlue in your diesel tank already, in Hall Green?

The short order of things, beginning with not starting your motor. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. Topping up with diesel will not thin it: rather than mixing, AdBlue drops to the bottom of your tank, right where the fuel is taken from.

If you're at a forecourt, whether it's the Asda or the Morrisons, ask the attendants to help roll the car clear of the pump. If you are on your own drive around Hall Green, leave the car where it is.

If the engine has already run, stop as soon as it is safe and switch off. Hall Green lies under 3 miles from the M6; on it, use the first exit. Tell us roughly how far it went: a run towards Wolverhampton, under 5 miles away, is a bigger job than a short hop across Hall Green.

When we arrive in Hall Green, what occurs?

By Wilkinson Primary School, near Saint John Fisher Roman Catholic Church or on your own driveway: wherever the car has stopped, our engineers come to it. We ask what was put in, about how much, and whether it has run, because those answers settle this work and our price. On the phone call itself, you hear our quote — before dispatch.

Emptying the tank comes next, then a thorough flush of the system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that matters more with AdBlue than with petrol. After the filter has been flushed — or renewed, where required — fresh diesel goes in, and then the vehicle gets tested. We do not go until it has been fired up and is running correctly.

If your engine has not run, most jobs take about half an hour once we're there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.
