AdBlue in a Diesel Tank in Mount Zion: Why It Occurs and How to Prevent It
Stop here a minute if your diesel tank already has AdBlue in it: ignition off, motor off, then phone 0333 366 0103. A drain and a full flush, carried out just where the car sits in Mount Zion, is normally what it takes if found before your motor runs. The remainder of this page covers why it happens and how to make sure it doesn't — useful if you're reading ahead of time.
AdBlue in a diesel motor, and its separate tank
Many newer diesels around Ffrith, as well as Mount Zion, carry on two fluids; the engine gets only the diesel. Your exhaust, not your motor, is where AdBlue goes: sprayed into the gas to clean it, from its own tank.
There is a filler on each tank. Many of cars have a single flap for both, while others put the AdBlue filler to the boot or under the bonnet. Topping up your diesel side at the pump goes on constantly. Far less regularly, the AdBlue side gets filled — normally from a bottle, by someone thinking about where it goes. That gap is where the error lives.
AdBlue in the diesel tank around Mount Zion: how it occurs
Carelessness seldom causes it. What does is three things coming up together.
The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the car goes into limp mode. So the top-up is done in a hurry: on a driveway off Mount Zion Road before work, or in the car park outside The Bluebell Inn on the way home.
New-to-you cars come second, as well. Rentals, new motors and company motors put their fillers in new places, and habit goes for the cap used on the old one.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started. It's a few seconds, be it in Brymbo or bang in the centre of Mount Zion.
How to tell the AdBlue filler from the diesel one
Before you tip anything, whether on a driveway in Moss or a forecourt in Mount Zion, check these. They take a couple of seconds.
- Where it sits misleads; the cap doesn't. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel caps normally do not.
- Check the size: the smaller neck is, on plenty of motors, the AdBlue one.
- Check inside your fuel flap: many motors have a label there saying which fuel goes where.
- Can't see it beside the diesel inlet? Then check below the bonnet or inside your boot — the owner's manual says where.
- The person who drove the car last. On a hire or company car collected from somewhere like the car park outside Cefn-Y-Bedd, ask before you leave, not when the light comes on.
Keeping AdBlue out of your diesel tank when you top up
For the day the warning appears — anywhere you are across Wrexham — a simple routine to use.
- Turn off after you park — level ground, engine off, and not rushed by Pool Road at the roadside.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
- The two behind one flap? Then make sure the lid on the diesel side is still shut before raising the bottle.
- Finish once that tank is topped up or the bottle is empty; before that, pour gently through its own spout.
- Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.
If at stage two or three you find you have already poured into your diesel side, stop there. Don't go on to step five.
Mount Zion: already put AdBlue in the diesel tank?
Then the order of things is short. Do not start your motor. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where the fuel is pulled from — so do not top up with diesel to thin it.
At a forecourt — Asda, Shell or another — the staff will usually help roll the car clear, when you ask. At home in Mount Zion? Then the vehicle remains put.
If your engine has already run, stop as soon as it is safe and switch off. Leave the M56 — under 15 miles out of Mount Zion — at the first exit. Mileage counts — a quick hop across Mount Zion is a smaller job than heading under 5 miles to Wrexham — so say roughly how far it went.
When we get there around Mount Zion, what occurs?
By the local primary school, near Brymbo Library or on your own drive: wherever your car has stopped, we come to it. Those replies decide this work and the quote, so we ask what went in, roughly how much, and if it has run. During the call itself, you hear the price — ahead of anything else.
Draining your tank comes next, followed by a thorough flush of the fuel system. More than with petrol, it counts here: the crystals form, certain metals corrode, and none of that clears out unaided, however long it sits. The filter flushed or, if it must be, swapped; clean diesel in; and then a test of your vehicle. The motor is started next and tested to be sure it runs correctly, all before our technicians go.
If the motor has not run, most jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. No money upfront; you settle up on the day. At the end, a VAT invoice and the report from the engineer go to you for your insurer. While we travel, have a look at your policy; many carry cover for misfuelling.
