AdBlue in a Diesel Tank in Eccleston Park: How It Happens and How to Prevent It

AdBlue in a diesel car, and its separate tank

Many modern diesels around Holt, like those in Eccleston Park, carry on two liquids; the motor takes only your diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has its own filler. Under one flap, side by side: that is the arrangement on a lot of motors. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. The diesel side is filled at the petrol pump all the time. Seldom topped up, AdBlue usually comes from a bottle, poured by someone who must stop and think what cap it needs. The mistake grows in that gap between the two.

AdBlue in the diesel tank in Eccleston Park: how it occurs

Seldom is it carelessness: normally three things coincide.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, your vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Fairholme Avenue before work, or in the car park outside The Wellington on the way home.

Then, the hand reaches for the cap it would have used on the old car — because a rental car, a new vehicle or a company car puts the fillers where your last one didn't.

A spout-topped bottle meets no resistance at a diesel filler any more than at an AdBlue one. So the tip, after begun, carries on. It takes seconds, whether in Eccleston Lane Ends or right in the heart of Eccleston Park.

Flushing a diesel fuel system after AdBlue, Eccleston Park

The AdBlue filler and your diesel filler: telling them apart

Look at these before pouring, on a forecourt in Eccleston Park or a driveway out in Grange Park. A few seconds, that's all.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap normally is not. Read it rather than going by where it sits.
  • The size. On many vehicles the AdBlue filler neck is the smaller of the two.
  • A label inside your fuel flap often says which fuel goes where, on many vehicles. Look for it.
  • The handbook. If the filler isn't by your diesel cap, it's in your boot or under the bonnet, and the handbook says which.
  • Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside the nearest station.

Topping up AdBlue without it reaching the diesel tank

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

  • Not in a rush on the side of Old Lane, not on a slope, not with your motor running: park then switch off properly.
  • Daft as it sounds, saying "AdBlue" aloud as you unscrew the cap works — once you have located your filler and read it.
  • The diesel cap stays on. Where both share a flap, make sure it is shut before the bottle comes up.
  • Finish when your tank fills or the bottle runs dry; until then, tip slowly using the built-in spout.
  • Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the vehicle.

Spot at step two or three that it has already gone into your diesel side? Then stop just there. Don't carry on to step five.

Put AdBlue in the diesel tank in Eccleston Park already?

Brief order, then. Top of that: the motor stays off. On many diesels the ignition alone runs the fuel pump, so do not switch it on. Topping up with diesel won't weaken it: instead, AdBlue sinks to the bottom of the tank, right where fuel is drawn from.

If you're on a forecourt, whether it's the Texaco or the Tesco, ask the attendants to help roll the vehicle clear of the pump. Your own driveway in Eccleston Park is the place it should stay.

Where the motor has run already, stop safely then turn the vehicle off. On the M57, under 3 miles from Eccleston Park, that means the next junction. About how far did it go? Crossing Eccleston Park is less a job than a trip of under 10 miles to Liverpool, so say.

Eccleston Park: what happens when our technicians get there

The van comes to the vehicle anywhere it stopped — your own drive, beside St James, or outside Eccleston Lane Ends Primary School. Those answers decide the work and our price, and so our engineers ask what was put in, roughly how much, and whether it has run. Nobody sets off before you've had the quote over the phone.

The system is then cleaned thoroughly, after the tank is cleared. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why that matters more with AdBlue than with petrol. The filter flushed or, if it must be, swapped; fresh diesel in; and then a test of the car. Then our technicians start the car and confirm it runs smoothly before we go.

If your engine hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. Payment is on the day, not upfront, and you receive the paperwork an insurer wants: an engineer's report and a VAT invoice. While we travel, have a look at your policy; plenty carry cover for misfuelling.
