Preventing AdBlue in a Diesel Tank in Mornington Meadows: Why It Happens
Pause reading a minute if your diesel tank already has AdBlue in it: ignition off, motor off, then phone 0333 366 0103. Around Mornington Meadows, catching it before your motor runs usually means a drain and a thorough flush on the spot. The rest of this page explains why it occurs and how to ensure it doesn't — handy if you are reading ahead of time.
AdBlue in a diesel vehicle, and its separate tank
Diesel goes to your motor — but many newer diesels driven about Mornington Meadows and Trethomas carry another liquid too. AdBlue's own tank keeps it, and from there it goes to the exhaust, and there spraying cleans the gas.
Every tank has a filler of its own. Under one flap, next to each other: that's the layout on a lot of vehicles. On others, AdBlue's filler is under the bonnet or in the boot instead. At the pump, the diesel side gets filled constantly. Much less often, the AdBlue side is topped up — mostly from a bottle, by someone working out where it goes. The error lives in that gap.
Mornington Meadows: how AdBlue in your diesel tank happens
Carelessness seldom causes it. What does is three things coming up together.
On a driveway off LLwyn Eithin before work, or in the car park at The Fisherman's Rest on the way home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue runs low the car warns you, and if it is empty, limp mode follows.
Unfamiliar motors are next, as well. Rentals, new motors and company cars place their fillers in new places, and the hand goes for the cap it used on the old one.
No part stops the tip after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Lansbury Park or the heart of Mornington Meadows: it is the same few seconds either way.
Which filler is for AdBlue, and which for diesel?
Before you pour anything, whether on a drive in Van or a forecourt in Mornington Meadows, check these. They take a couple of seconds.
- Where it sits can mislead; the cap doesn't. AdBlue caps are often blue or bear the word "AdBlue" — diesel caps usually don't.
- On plenty of vehicles, size tells: AdBlue gets the smaller filler neck.
- Look inside the fuel flap: plenty of cars have a label there showing which fuel goes where.
- The handbook says which it lives when your filler is not next to your diesel cap: your boot, or under the bonnet.
- The person who drove the car last. On a hire or company car picked up from somewhere like the car park outside Caerphilly, ask before you leave, not when the light comes on.
AdBlue top-ups that never reach your diesel tank
Anywhere across Caerphilly the light comes on, this is a routine for the day.
- Switch off once parked — level ground, motor off, and not in a rush beside Gwaun Hyfryd at the roadside.
- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Silly, perhaps, yet it works.
- The diesel cap remains on. Where the two share a flap, confirm it's shut before the bottle comes up.
- Finish when that tank is topped up or the bottle is empty; before that, pour gently using its own spout.
- Shut the cap, then check again — making sure your diesel cap remained shut the whole time. Only then, start the car.
Stop there if you find, at stage two or three, that you've already poured into your diesel side. Skip step five altogether.
Already put AdBlue in your diesel tank in Mornington Meadows?
Do not start the motor: that is how the short order of things starts. The fuel pump starts on plenty of diesels as soon as the ignition is switched on — so leave it off. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is drawn from — so do not top up with diesel to dilute it.
The staff at Morrisons, Asda or any forecourt will usually help pushing the vehicle away when asked. If you are on your own driveway around Mornington Meadows, leave the vehicle where it stands.
If your motor has already run, stop as soon as it is safe and switch off. The next junction means the place to leave when you're on the M4, under 3 miles from Mornington Meadows. A short hop across Mornington Meadows is a smaller job than a run towards Cardiff, under 10 miles away, and so tell us roughly how far it went.
Our arrival in Mornington Meadows, and what takes place next
Our van reaches the vehicle anywhere it stopped — your own driveway, beside Bedwas RFC, or outside the local primary school. The replies determine this work and the price, so our engineers ask what got in, roughly how much, and if it's run. On the call itself, you hear our price — before anything else.
Draining the tank comes next, then a thorough flush of your system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. A test comes at the end: before that, fresh diesel goes in, and your filter is flushed or replaced as needed. Your engine is fired up next and checked to be sure it runs smoothly, all before our engineers leave.
Using pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which the engine has not run need roughly half an hour once our engineers arrive. Payment happens on the day, not upfront, and you are given the documents an insurer asks for: an engineer's report and a VAT invoice. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way.
