Roxburghs Court: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
If AdBlue is already in your diesel tank, stop reading for a moment: leave the motor and your ignition off and phone 0333 366 0103. Usually, when the engine hasn't turned, it's emptied and fully cleaned where the car is in Roxburghs Court. Not happened yet? Further down, the page explains the reasons it happens and the how to prevent it for good.
Two fillers, two tanks: AdBlue in a diesel motor
Plenty of modern diesels on the roads round Roxburghs Court and New Town carry two liquids, not one. Diesel goes to the motor. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.
Each tank has its own filler. Plenty of motors share a single flap for the two, whereas others move the AdBlue filler to your boot or under the bonnet. The diesel side is fuelled at the petrol pump all the time. Someone who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less commonly. The error lives in that gap.
AdBlue in the diesel tank in Roxburghs Court: how it occurs
It's seldom carelessness. Three things tend to line up.
To start with, the warning. Low AdBlue brings a message from your car, and running out leads to limp mode — hence a hurried top-up, maybe before work off High Street, perhaps outside Devil's Advocate on the way home after work.
Then the vehicle is strange. A hire car, a new car or a company car puts the fillers where your last one did not, and the hand hits for the cap it would have 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 tip once it has started. It takes seconds, whether in Old Town or right in the heart of Roxburghs Court.
The AdBlue filler and your diesel filler: telling them apart
Before you tip anything, whether on a driveway in Dumbiedykes or a forecourt in Roxburghs Court, check these. They take a couple of seconds.
- Colour and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not its position.
- Many vehicles give AdBlue the smaller filler of the two.
- Look inside the fuel flap: many cars have a label there saying which fuel goes where.
- The handbook. If your filler is not by your diesel cap, it's in your boot or under the bonnet, and the handbook says which.
- The previous driver will know. Check as you collect a rental or fleet car — at Edinburgh Waverley's car park, perhaps — rather than once the warning comes on.
Topping up AdBlue without it reaching your diesel tank
When the light goes on, anywhere around City of Edinburgh, use this routine.
- Switch off after you park — flat ground, engine off, and never in a rush beside Parliament Square on the verge.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
- Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
- Gently does it, through the bottle's own spout, until it is full or the bottle runs out.
- Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start your car.
Stop there if you find, at step two or three, that you have already poured into the diesel side. Never go on to stage five.
AdBlue in the diesel tank already, in Roxburghs Court?
Short order, then. Top of it: your engine stays off. The fuel pump runs on many diesels the moment the ignition goes on — and so keep it off. Do not top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where the fuel is sucked from.
If you are at a forecourt, whether it is the JET or the BP, ask the attendants to help push the vehicle away from the pump. Your own drive in Roxburghs Court is where it stays.
If the motor has already run, stop as soon as it is safe then switch off. Come off the M8 — under 5 miles out of Roxburghs Court — at the first junction. Tell us about how far it went: a run towards Edinburgh, under a mile away, is a bigger job than a short hop across Roxburghs Court.
When we arrive around Roxburghs Court, what takes place?
Outside the local primary school, near The Real Mary King's Close or on your own driveway: wherever the vehicle has stopped, our technicians come to it. Which liquid was put in, the amount, and if it ran: our engineers ask since the replies decide both work and quote. No one sets off before you've heard our quote over the phone.
Then your tank is emptied and your system rinsed thoroughly. Much more than with petrol, it counts with AdBlue: crystals build up, certain metals are attacked, and nothing washes out on its own, however long it is left. A test comes last: before that, fresh diesel goes in, and the fuel filter is cleaned or changed as needed. We do not go until it has been fired up and is running correctly.
With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs where your motor hasn't run need roughly half an hour once our engineers are there. Nothing in advance; you settle up on the day. At the end, the VAT invoice and the report from the engineer go to you for the insurer. It's worth checking your insurance as the van travels to you: misfuelling cover comes with many policies.
