Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Ynyswen
AdBlue already in your diesel tank? Then put this page aside a moment, leave the ignition and motor off, and phone 0333 366 0103. Normally, when your motor hasn't run, it's emptied and thoroughly rinsed where the vehicle is around Ynyswen. If you are reading before it has happened, the rest of this page is about why it happens and how to make sure it does not.
AdBlue in a diesel vehicle: two tanks, two fillers
Plenty of modern diesels in Treherbert, as well as Ynyswen, run on two fluids; your engine takes just the diesel. Its own tank keeps it, and from there it is sent to the exhaust, and there spraying treats the gas.
There is a filler for every tank. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel goes in on each filling station visit, again and again. The AdBlue side is fuelled far less commonly, normally from a bottle, and normally by someone who has to stop and think where it goes. Mistakes happen in the gap between them.
How AdBlue in your diesel tank occurs in Ynyswen
Three things tend to come together, and carelessness is rarely one of them.
The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the car drops into limp mode. So the top-up is done in a hurry: on a driveway off Ynyswen Road before work, or in the car park at The Lion on the way home.
New-to-you motors come second, as well. Hire cars, new vehicles and company cars put their fillers differently, and the hand reaches for the cap it used on the old one.
A spouted bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, after started, keeps on. It takes seconds, be it in Treorchy or right in the centre of Ynyswen.
Telling the AdBlue filler from your diesel filler
A couple of seconds is all the checks take — so check them before you pour anything, on a drive in Tynewydd or a forecourt around Ynyswen.
- Check the cap instead of going by where it sits: AdBlue caps are often blue or marked "AdBlue", and diesel ones normally aren't.
- On many vehicles, the size tells: AdBlue gets the smaller filler neck.
- The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
- In your boot or under the bonnet: that is where the filler is if it's not by your diesel cap, and the handbook says which.
- Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at the nearest station.
How to top up without AdBlue in your diesel tank
Anywhere around Rhondda Cynon Taf the light comes on, here is a routine for that day.
- Pull in somewhere level, engine off, with time to spare — not rushing on the side of Mace Lane.
- 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 a single flap? So make sure the cap on the diesel filler is still closed ahead of lifting the bottle.
- Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Only after that, start your car: close the cap, check a second time, and make sure the diesel cap was never opened.
Stop there if you find, at stage two or three, that you've already poured into the diesel side. Do not go on to step five.
Already put AdBlue in your diesel tank around Ynyswen?
Short list, then. Top of it: your motor stays unstarted. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where the fuel is sucked from.
If you are on a forecourt, whether it's the Texaco or the Murco, ask the staff to help push the car away from the petrol pump. At home in Ynyswen? So your car stays where it is.
Already run? Pull over when it's safe, then switch off. On the M4, under 10 miles from Ynyswen, that means the next junction. Tell us roughly how far it went: a run towards Swansea, under 25 miles away, is a bigger job than a short hop across Ynyswen.
Our arrival in Ynyswen, and what happens next
Outside the local primary school, close to Ynyswen Welfare Hall or on your own driveway: wherever the car has stopped, our engineers come to it. Which fluid got in, the amount, and if it ran: our technicians ask since the replies set both work and quote. On the call itself, you are told our price — before anything else.
After that: draining, then a full flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why the flush matters more with AdBlue than with petrol. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Before we go, our technicians fire it up and make sure that it is running correctly.
If your motor hasn't run, the majority of jobs take about half an hour once we are 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 that day. At the end, a VAT invoice and a report from the engineer are handed to you for the insurer. While we travel, have a look at your policy; plenty carry cover for misfuelling.
