Why It Happens and How to Prevent It: AdBlue in a Diesel Tank in Beadlam

Leave your engine and ignition off then call 0333 366 0103 now — the rest can wait if AdBlue is already in your diesel tank. Usually, when the motor has not run, it is drained and thoroughly cleaned where the vehicle is in Beadlam. Reading before the event? Then what follows explains why it happens and how to prevent it happening at all.

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

Diesel goes to your motor — but plenty of modern diesels seen about Beadlam and Harome hold a second fluid too. The exhaust, not the motor, is where AdBlue goes: dosed into the fumes to clean it, from a separate tank.

Different tanks, separate fillers. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is filled at the petrol pump all the time. The AdBlue side is filled far less regularly, usually from a bottle, and usually by a person who has to stop and think where it goes. The mistake grows in the gap between the two.

Beadlam: how AdBlue in your diesel tank occurs

It is rarely carelessness. Three things tend to line up.

On a drive off The Orchards before work, or in the car park outside Rose and Crown heading home: that is where the hurried top-up happens. Why the rush? As AdBlue runs low the vehicle tells you, and once it's gone, limp mode follows.

The old car's cap is where your hand reaches — but a hire car, a new vehicle or a company car keeps the fillers somewhere else. That is the second factor: a new motor.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. Whether it takes place in Nawton or the middle of Beadlam, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Beadlam

Telling the AdBlue filler from your diesel filler

A few seconds is all the checks take — so check them before you tip anything, on a driveway in Welburn or a forecourt around Beadlam.

  • Blue and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not where it sits.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside your fuel flap for a label. Many motors say there which fuel goes where.
  • The handbook. If your filler is not by the diesel cap, it's in the boot or under the bonnet, and the handbook says which.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Malton.

Topping up AdBlue without it reaching your diesel tank

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

  • Pull in on level, motor off, with time in hand — never rushing on the side of Birklands.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, yes, but it does the trick.
  • The diesel cap stays on. When both sit under a flap, confirm it's closed before the bottle comes up.
  • Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
  • Only after that, start the vehicle: close the cap, check a second time, and make sure your diesel cap was never opened.

Stop there if you find, at step two or three, that you have already poured into the diesel side. Do not go on to stage five.

Beadlam: already put AdBlue in your diesel tank?

Short list, then. Top of that: your motor remains off. Leave the ignition off too, because on many diesels switching it on alone runs the pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is sucked from — so do not top up with diesel to thin it.

If you are on a forecourt, whether it is the BATA Ltd or the JET, ask the attendants to help roll your car away from the petrol pump. At home in Beadlam? Then your car stays put.

Where the motor has been run by now, pull over safely and switch the vehicle off. The next junction means where to leave if you're on the A1(M), under 25 miles from Beadlam. Distance matters — a quick hop across Beadlam is a smaller job than driving under 25 miles to York — so tell us roughly how far it went.

What occurs when we arrive around Beadlam

Outside Nawton Community Primary School, near Nawton Memorial Hall or on your own drive: wherever your car has stopped, our technicians come to it. Which fluid went in, the amount, and whether it ran: our technicians ask since those replies decide the work and quote. You hear that price on the phone, before anyone heads out.

The fuel system is then cleaned thoroughly, once that tank is cleared. Unlike petrol, AdBlue leaves crystals and attacks some fuel-system metals, and none of it clears away by itself. That is why it counts more. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. We do not go until it has been started and is running correctly.

If your engine has not run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. Nothing upfront; you settle up on the day. At the end, a VAT invoice and a report from the engineer are handed to you for your insurer. It is worth checking your insurance as the van travels to you: misfuelling cover comes with many policies.

Beadlam and North Yorkshire: AdBlue drains across the area

Beadlam is a rural village, and our teams that cover it also work the towns near it, Wombleton and Pockley among them, across the YO postcode area. Give a postcode beginning YO62 7, and the van gets there fastest.

Your car remains where it is. A drive, a lay-by on the way to Beckett Recreation Ground, a side street close to St Hilda's: we drain the vehicle where it is. Ring and ask rather than guessing if you're close to a border, or somewhere hard to explain, like the back of Drama Studio.
