Preventing AdBlue in a Diesel Tank in Llwynbrwydrau: Why It Occurs
Leave the engine and ignition off and phone 0333 366 0103 now — reading can wait if AdBlue is already in your diesel tank. A drain plus a full flush, carried out just where the car stands around Llwynbrwydrau, is usually what it takes when caught before the motor runs. If you're reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't.
AdBlue in a diesel motor: two tanks, two fillers
No single fluid but two: that is what many newer diesels near Llwynbrwydrau and Trallwn run, with diesel for the motor. Its own tank keeps it, and from there it goes to your exhaust, and there spraying treats the fumes.
Separate tanks, separate fillers. Many of motors share a single flap for both, whereas some move the AdBlue filler to the boot or under the bonnet. At the petrol pump, your diesel side is topped up constantly. Much less frequently, the AdBlue side is filled — mostly from a bottle, by a person working out where it goes. That gap is where the error lives.
Llwynbrwydrau: how AdBlue in the diesel tank takes place
Seldom is it carelessness: normally three things line up.
First, the warning. Low AdBlue brings a message from the vehicle, and running out leads to limp mode — hence a rushed top-up, perhaps before work off M4, or outside The Halfway on the way home after work.
Next, your hand reaches for the cap it knew on the old motor — since a hire car, a new car or a company car places the fillers where your last one didn't.
A spout-topped bottle meets no obstacle at a diesel filler no more than at an AdBlue one. So the pour, once begun, keeps on. It takes seconds, be it out in Lon-las or bang in the heart of Llwynbrwydrau.
The AdBlue filler and the diesel filler: telling them apart
A couple of seconds is all the checks take — so check them before you pour anything, on a drive in Pentre-dwr or a forecourt around Llwynbrwydrau.
- The cap. The AdBlue cap is commonly blue, or marked "AdBlue". The diesel cap usually is not. Read it instead of going by position.
- Check the size: the smaller filler neck is, on plenty of cars, the AdBlue one.
- The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where.
- Cannot see it beside your diesel inlet? Then look beneath the bonnet or in the boot — the handbook says which.
- Collecting a hire or company car, perhaps at the car park outside Llansamlet? Ask the person who drove it last before leaving, rather than once the light goes on.
How to top up without AdBlue in your diesel tank
Wherever across Swansea the light comes on, here is a routine for that day.
- Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Peniel Green Road.
- Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and reading it. Silly, perhaps, but it does the trick.
- The diesel cap remains on. Where both share a flap, make sure it's closed before lifting the bottle.
- Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
- Before starting the car, shut the cap and look again that the diesel cap never opened off.
If at step two or three you find you have already poured into your diesel side, stop there. Do not go on to stage five.
Already put AdBlue in your diesel tank in Llwynbrwydrau?
Short order, then. First: your motor stays off. Keep your ignition off too, because on many diesels switching it on by itself runs your fuel pump. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where the fuel is drawn from.
Ask the staff to help push the vehicle clear of the pump if you are on a forecourt — the the nearest petrol station, the Texaco or somewhere else. Your own drive around Llwynbrwydrau is where it should stay.
Already run? Pull over once it's safe, then turn off. Leave the M4 — under a mile out of Llwynbrwydrau — at the first exit. Mileage matters — a short hop across Llwynbrwydrau is a smaller job than driving under 5 miles towards Swansea — so say about how far it went.
Our arrival around Llwynbrwydrau, and what happens next
By the local primary school, near Guru Nanak Sikh Community Centre or on your own drive: wherever the vehicle has stopped, we come to it. Our engineers ask what was put in, about how much, and if it's run, because those answers settle this work and our quote. You hear that quote by phone, before anybody heads out.
The system is then purged thoroughly, after your tank is drained. Not like petrol, AdBlue forms crystals and attacks some fuel-system metals, and none of it washes away by itself. Hence it matters more. Testing is at the end: before that, fresh diesel is added, and the filter is flushed or changed as needed. Before we go, our engineers start the engine and make sure that it is running properly.
Using pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs in which your engine has not run take about half an hour after our engineers are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth looking at your policy as the van travels to you: misfuelling cover comes with many policies.
