Avoiding AdBlue in a Diesel Tank in Juniper Green: Why It Occurs
AdBlue already in the diesel tank? Then set this page down for now, keep your ignition and motor off, then call 0333 366 0103. Caught before your engine runs, it's usually a drain and a thorough flush, done where your car is in Juniper Green. Nothing happened yet? Further down, the rest of the page explains the why it occurs and the ways to prevent it for good.
Two fillers, two tanks: AdBlue in a diesel motor
Many modern diesels around Bonaly, like those in Juniper Green, carry on two liquids; your engine takes just your diesel. Kept in a tank of its own, AdBlue is fed into your exhaust gas to clean it.
Each tank has its own filler. Some vehicles keep the AdBlue filler in the boot or under the bonnet; a lot more have both together under one flap. Diesel goes in on every filling station visit, again and again. Rarely filled, AdBlue usually comes out of a bottle, tipped by a driver who must stop and think what cap it needs. That gap is where the slip lives.
AdBlue in the diesel tank around Juniper Green: how it happens
Carelessness seldom explains it. Instead is three things coming up together.
To start with, the warning. Low AdBlue triggers a message from the vehicle, and letting it run out leads to limp mode — so a hurried top-up, maybe before work off Viewfield Road, perhaps outside Tanners on the way home that evening.
The old car's filler is where your hand goes — but a hire car, a new car or a company car keeps the fillers elsewhere. That's a second factor: a new car.
A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. So the tip, after started, keeps on. It's seconds, be it in Hailes or right in the centre of Juniper Green.
Telling the AdBlue filler from the diesel filler
Whether a Juniper Green forecourt or a drive over in Kingsknowe, take a couple of seconds over these before anything is poured in.
- Colour and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not its position.
- Plenty of vehicles give AdBlue the smaller neck of the two.
- Check inside your fuel flap: many cars carry a label there saying which fuel goes where.
- The handbook. If the filler is not by your diesel cap, it's in your boot or under the bonnet, and the handbook says which.
- Picking up a hire or company car, perhaps at the car park outside Wester Hailes? Ask whoever drove the vehicle last before leaving, rather than when the light goes on.
Topping up AdBlue without it reaching your diesel tank
For the day the light comes on — wherever it is in City of Edinburgh — a simple routine to use.
- Switch off after you park — flat ground, motor stopped, and not rushed by Gillespie Road at the roadside.
- Daft as it sounds, saying "AdBlue" aloud as you unscrew the cap works — once you have found the filler and read it.
- The diesel cap stays on. Where the two sit under a flap, make sure it is closed before the bottle comes up.
- Slowly does it, through the bottle's own spout, until it's full or the bottle is empty.
- Before starting your car, close the cap and check a second time that your diesel cap never came off.
Stop there if you find, at step two or three, that you've already poured into the diesel side. Don't go on to stage five.
Juniper Green: already put AdBlue in the diesel tank?
Don't start the motor: that is how the short order of things begins. Keep your ignition off as well, since on many diesels switching it on by itself runs your fuel pump. Diluting it with more diesel won't work, because AdBlue settles to the bottom rather than blending — and that's where the fuel is sucked from.
The staff at BP, Sainsbury's or another forecourt will normally help pushing the vehicle away when you ask. If you are on your own drive around Juniper Green, leave it where it is.
If the engine has already run, stop as soon as it is safe and switch off. The next exit is the place to leave when you are on the M8, under 3 miles from Juniper Green. A short hop across Juniper Green is a smaller job than a run towards Edinburgh, under 5 miles away, so tell us about how far it went.
Juniper Green: what occurs when we arrive
Outside the local primary school, near Wester Hailes Baptist Church or on your own drive: wherever the vehicle has stopped, our engineers come to it. Our engineers ask what went in, roughly how much, and whether it's run, since those answers determine this work and our quote. You hear that quote by phone, before anybody sets off.
Your system is then purged thoroughly, once your tank is cleared. Unlike petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of it clears away unaided. That is why it counts more. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Before we leave, our engineers start the car and confirm that it is running smoothly.
Unstarted vehicles usually mean a half-hour job after arrival. The equipment is fine on a live filling station, and hushed enough for a driveway late at night. The insurer usually wants the engineer's report and your VAT invoice, and you get both at the end. Payment comes on the day, with no money upfront. It's worth looking at your insurance while we travel to you: misfuelling cover is included with many policies.
