Avoiding AdBlue in a Diesel Tank in Llandeilo: Why It Occurs
AdBlue already in the diesel tank? In that case put this page down a moment, keep the ignition and engine off, and call 0333 366 0103. Normally, when the engine hasn't run, it is emptied and fully rinsed where the car sits around Llandeilo. The remainder of this page explains why it occurs and how to make sure it doesn't — handy if you're reading before it has happened.
AdBlue in a diesel motor, and its separate tank
Many current diesels on the roads about Llandeilo and Pen-y-banc carry two liquids, not one. Diesel goes to the engine. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.
There is a filler for each tank. Under one flap, next to each other: that is the arrangement on many cars. On others, AdBlue's filler sits beneath the bonnet or in the boot instead. At the petrol pump, the diesel side gets filled constantly. Someone who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and far less commonly. The slip lives in that gap.
AdBlue in the diesel tank around Llandeilo: how it happens
Three things tend to line up, and carelessness is seldom one of them.
Hurry follows from the warning. The vehicle tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off Rhosmaen Street, or on the way home in the car park at White Horse Inn.
Next, your hand goes for the cap it would have used on the old vehicle — since a rental car, a new vehicle or a company car puts the fillers somewhere your last one didn't.
A spout-topped bottle finds no resistance at a diesel filler any more than at an AdBlue one. And so the tip, once begun, carries on. Whether it occurs in Ffairfach or the middle of Llandeilo, it's the same few seconds.
How to tell the AdBlue filler from the diesel one
A couple of seconds is all the checks take — so run through them before you pour anything, on a drive in Pontbren Araeth or a forecourt around Llandeilo.
- Where it sits can mislead; the cap does not. AdBlue caps are often blue or bear the name "AdBlue" — diesel ones normally don't.
- Plenty of vehicles fit AdBlue the smaller neck of the two.
- Open the flap and check for a label — plenty of motors mark which goes in each filler right there.
- The handbook says where it lives when your filler is not next to your diesel cap: your boot, or under the bonnet.
- Check with 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 the diesel tank
A routine for the day the light comes on, wherever around Carmarthenshire that is.
- Not in a rush on the side of Carmarthen Street, not on a slope, not with the motor running: park then switch off first.
- Locate the AdBlue filler, check the cap, and say the word "AdBlue" aloud as unscrewing it. It seems silly. It works.
- The diesel cap stays on. Where both sit under a flap, make sure it's closed before lifting the bottle.
- Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Shut the cap, then check again — making sure the diesel cap remained shut the whole time. After that, start the vehicle.
If at step two or three you find you have already poured into the diesel side, stop there. Step five is out.
AdBlue in your diesel tank already, in Llandeilo?
Don't start the engine: that is where the short order of things starts. The fuel pump runs on many diesels the moment your ignition goes on — and so keep it off. Topping up with diesel will not thin it: instead, AdBlue drops to the base of that tank, right where the fuel is taken from.
Ask the attendants to help roll the car clear of the pump if you're at a forecourt — the Oil 4 Wales, the another forecourt nearby or anywhere else. On your own drive in Llandeilo? So your car stays where it is.
If your engine has already run, stop as soon as it is safe then switch off. On the M4, under 10 miles from Llandeilo, that means the next junction. Roughly how far did it go? Crossing Llandeilo is smaller a job than a trip of under 25 miles towards Swansea, so say.
Llandeilo: what happens when our technicians turn up
By the local primary school, close to Llandeilo Fawr Town Council or on your own driveway: wherever the vehicle has stopped, our engineers come to it. What fluid was put in, the amount, and if it ran: we ask because the replies set the work and quote. On the call itself, you hear our price — ahead of dispatch.
Next: a drain, then a full flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush matters more here than with petrol. Once your filter is cleaned — or replaced, if needed — clean diesel goes in, and then your car gets tested. Before leaving, our engineers fire it up and confirm that it is running properly.
If your engine hasn't run, most jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, take a look at your insurance documents; many carry cover for misfuelling.
