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

Stop here for a moment if your diesel tank already holds AdBlue in it: ignition off, motor off, and ring 0333 366 0103. Caught before your engine runs, it is usually a drain and a thorough flush, done where your car is around Lenziemill. Reading in advance? Then what follows explains how it comes about and what to stop it ever happening.

Two fillers, two tanks: AdBlue in a diesel car

Plenty of modern diesels on the roads around Lenziemill and Greenfaulds carry two liquids, not one. Diesel goes to the engine. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Different tanks, separate fillers. Many of vehicles have a single flap for the two, whereas others move the AdBlue filler to the boot or under the bonnet. The diesel side is filled at the pump all the time. The AdBlue side is topped up far less frequently, usually from a bottle, and normally by a person who has to stop and think where it goes. It is in that gap that the error happens.

AdBlue in the diesel tank around Lenziemill: how it occurs

Carelessness seldom causes it. What does is three things coming up at once.

Hurry comes from the warning. Your car tells you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off Kelvin Road North, or on the way home in the car park at Burroughs Club.

Then, your hand reaches for the cap it knew on the old motor — since a hire car, a new motor or a company car puts the fillers where your last one didn't.

Lastly, the spout fits: a diesel filler or AdBlue one, it slides in just as readily, and after the tip begins, no part halts it. Whether it takes place in Luggiebank or the middle of Lenziemill, it is the same few seconds.

How to tell the AdBlue filler from the diesel one

Check these first, at a forecourt in Lenziemill or a driveway out in Blairlinn. A few seconds, no more.

  • The cap. The AdBlue cap is commonly blue, or marked "AdBlue". The diesel cap usually isn't. Read it rather than going by position.
  • Look at the size: the smaller filler neck is, on many vehicles, the AdBlue one.
  • Check inside the fuel flap: plenty of cars have a label there saying which fuel goes where.
  • The handbook. If your filler isn't by the diesel cap, it is in your boot or under the bonnet, and the handbook says which.
  • The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Cumbernauld, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach the diesel tank

The day the light comes on, wherever across North Lanarkshire, follow this routine.

  • Not in a rush on the side of Telford Road, not on a slope, not with your motor running: park then switch off first.
  • Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap works — once you've found the filler and read it.
  • The two under one flap? Then make sure the lid on your diesel side is still closed before lifting the bottle.
  • Finish once your tank is topped up or the bottle runs dry; until then, pour slowly using the own spout.
  • Close the cap and check again. Make sure your diesel cap was never opened. Only then start the car.

Stop there if you find, at step two or three, that you have already poured into your diesel side. Never go on to step five.

AdBlue in the diesel tank already, around Lenziemill?

The short order of things, starting with no starting your motor. The fuel pump starts on plenty of diesels the moment the ignition is switched on — and so leave it off. Filling up with diesel will not weaken it: instead, AdBlue drops to the bottom of your tank, just where fuel is taken from.

If you are on a forecourt, whether it is the Highland or the Tesco, ask the staff to help roll your car away from the pump. Your own driveway in Lenziemill is the place it should stay.

When your motor has been run already, pull over safely and switch the car off. On the M80, under 3 miles from Lenziemill, that means the next junction. A short hop across Lenziemill is a smaller job than a run towards Glasgow, under 15 miles away, so tell us roughly how far it went.

What happens when our engineers get there in Lenziemill

Our technicians come to the car wherever it has stopped, whether that's outside the local primary school, close to Cumbernauld Free Church or on your own driveway. Both the work and the quote rest on three replies — what liquid, which amount, and whether it's run — so our technicians ask. On the phone call itself, you hear the price — before anything else.

The fuel system is then rinsed thoroughly, after your tank is cleared. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why that matters more here than with petrol. A test is last: before that, fresh diesel is added, and the fuel filter is cleaned or changed as needed. Before leaving, our engineers start the car and make sure that it is running correctly.

Most jobs are done in roughly half an hour once our technicians get there, provided your engine has not run — and the pumps our technicians use are fine on a busy forecourt yet quiet at night beside a house. The insurer usually wants the engineer's report and your VAT invoice, and you get both at the end. Payment is on the day, with no deposit. Before we get there, take a look at your policy; plenty include cover for misfuelling.
