Avoiding AdBlue in a Diesel Tank in Beauly: Why It Happens

Leave the engine and ignition off and ring 0333 366 0103 now — reading can wait when AdBlue is already in your diesel tank. Caught before your engine runs, it's normally a drain and a thorough flush, done where the vehicle is in Beauly. If you are reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not.

AdBlue in a diesel car, and its separate tank

No single liquid but two: that's what plenty of modern diesels near Beauly and Ruilick carry, with diesel feeding the engine. Its own tank holds it, and from there it goes to the exhaust, where spraying cleans the fumes.

Every tank comes with a filler of its own. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Topping up your diesel side at the pump happens all the time. Much less regularly, the AdBlue side gets topped up — mostly from a bottle, by a person thinking about where it goes. The mistake grows in that gap between them.

AdBlue in the diesel tank in Beauly: how it occurs

Seldom is it carelessness: usually three things coincide.

The warning comes first. As AdBlue runs low the vehicle 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 driveway off Croyard Road before work, or in the car park at The Comm on the way home.

The old car's cap is where the hand goes — yet a hire car, a new motor or a company car puts the fillers somewhere else. That is the second thing: a new motor.

Third, the bottle goes in: a diesel filler or AdBlue one, it goes in just as readily, and once the tip begins, no part halts it. The same few seconds decide it, in the middle of Beauly or out in Rheindown.

The AdBlue filler and the diesel filler: telling them apart

A couple of seconds is all the checks take — so run through them before you tip anything, on a drive in Wester Balblair or a forecourt in Beauly.

  • Read the cap rather than going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones usually are not.
  • The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
  • Check inside your fuel flap: many cars carry a label there showing which fuel goes where.
  • Can't see it next to the diesel inlet? Then check below the bonnet or inside the boot — the handbook says where.
  • The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

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

  • Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of High Street.
  • Daft as it sounds, speaking "AdBlue" out loud while you unscrew the cap does the trick — once you have found the filler and read the cap.
  • Both behind one flap? So confirm the cap on your diesel filler stays shut ahead of lifting the bottle.
  • Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Before you start your car, shut the cap and check a second time that your diesel cap was never came off.

If at stage two or three you find you have already poured into the diesel side, stop there. Stage five stays off limits.

Already put AdBlue in your diesel tank in Beauly?

What follows is a short order of things, beginning with no starting your motor. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. Diluting it with extra diesel won't work, since AdBlue sinks to the base rather than mixing — and that's where the fuel is drawn from.

On a forecourt — Gulf, Esso or any other — the staff will usually help push the vehicle away, if you ask. Your own drive in Beauly is where it stays.

When the engine has run by now, stop safely and turn the vehicle off. Beauly lies over 50 miles from the M90; there, use the next junction. A short hop across Beauly is a smaller job than a run towards Inverness, under 10 miles away, and so tell us roughly how far it went.

When our engineers get there in Beauly, what occurs?

Anywhere the car has stopped, whether by the local primary school, beside Lovat Memorial Garden or at home, our van travels to it. Our engineers ask what was put in, about how much, and whether it's run, since those answers determine the work and our quote. During the call itself, you are told the price — ahead of dispatch.

Then that tank is cleared and the fuel system purged thoroughly. 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 counts more here than with petrol. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Before we leave, our technicians start it and make sure that it is running correctly.

If the motor hasn't run, the majority of 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. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, have a look at your insurance documents; many carry cover for misfuelling.
