Preventing AdBlue in a Diesel Tank in Hemlington: Why It Happens

Keep your motor and ignition off and ring 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank. A drain and a thorough flush, carried out just where your vehicle stands around Hemlington, is usually what it takes when found before your motor runs. If you're reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't.

AdBlue in a diesel motor, and its separate tank

Not one liquid but two: that's what plenty of modern diesels near Hemlington and Coulby Newham carry, with diesel for your engine. Your exhaust, not the engine, is where AdBlue goes: dosed into the gas to fresh it, from a separate tank.

Each tank has its own filler. Many of cars have a single flap for the two, whereas some move the AdBlue filler to your boot or under the bonnet. Topping up your diesel side at the pump goes on constantly. A driver who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and far less regularly. It is in the gap that the error happens.

How does AdBlue in the diesel tank take place in Hemlington?

Three things tend to come together, and carelessness is seldom one of them.

On a drive off Crosscliff before work, or in the car park outside The Smithy heading home: that is where the rushed top-up takes place. Why the rush? As AdBlue gets low the car tells you, and once it is gone, limp mode kicks in.

Unfamiliar cars are next, as well. Rentals, new motors and company motors place their fillers differently, and the hand reaches for the cap it used on the old one.

No part stops the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it occurs in Brookfield or the middle of Hemlington, it's the same few seconds.

How to tell the AdBlue filler from the diesel one

A couple of seconds is all these take — so check them before you tip anything, on a drive in Tollesby or a forecourt in Hemlington.

  • Blue and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not its position.
  • The size. On many vehicles the AdBlue filler neck is the smaller of the two.
  • Open the filler flap and check for a label — many motors mark which belongs in each inlet just there.
  • In the boot or under the bonnet: that's where the filler is if it's not by your diesel cap, and the handbook says which.
  • Check with the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Marton.

AdBlue top-ups that never reach your diesel tank

Anywhere in North Yorkshire the light comes on, here is a routine for the day.

  • Not in a rush on the side of Corbridge Close, 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 does the trick — once you have found your filler and read the cap.
  • Both behind one flap? So make sure the lid on your diesel filler stays closed before raising the bottle.
  • Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Only after that, start the vehicle: close the cap, check once more, and make sure your diesel cap was never opened.

Spot at stage two or three that it's already gone into your diesel side? So stop right there. Do not go on to stage five.

AdBlue in your diesel tank already, in Hemlington?

Do not start your engine: that is how the short order of things starts. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where the fuel is drawn from — so don't top up with diesel to thin it.

If you are on a forecourt, whether it is the Esso or the Tesco, ask the staff to help push the vehicle clear of the petrol pump. If you're on your own driveway in Hemlington, leave the car where it stands.

Stop as soon as it is safe and switch off, if your motor has already run. On the A1(M), under 15 miles from Hemlington, that means the next exit. Tell us about how far it went: a run towards Durham, under 25 miles away, is a bigger job than a short hop across Hemlington.

Hemlington: what occurs when we arrive

The van reaches your car wherever it stopped — your own driveway, near Hemlington Baptist Church, or by Viewley Hill Academy. Both the work and our price depend on three replies — which liquid, which quantity, and if it has run — so our technicians ask. You hear that quote by phone, before anyone heads out.

Emptying that tank comes next, then a full flush of the system. Unlike petrol, AdBlue leaves crystals and attacks some fuel-system metals, and neither clears out unaided. That is why it counts more. A test comes last: before that, clean diesel is added, and the filter is flushed or replaced as needed. We don't leave until it has been fired up and is running smoothly.

Unstarted cars mostly mean a half-hour visit after arrival. The kit is fine on a live forecourt, and quiet enough for a residential street after dark. No money in advance; you settle up that day. At the end, a VAT invoice and a report from the engineer are handed to you for your insurer. While we travel, have a look at your policy; plenty carry cover for misfuelling.
