Preventing AdBlue in a Diesel Tank in Persondy: Why It Happens
Keep the engine and ignition off and phone 0333 366 0103 now — reading can wait when AdBlue is already in the diesel tank. Normally, if your motor has not run, it's drained and fully purged where the car is around Persondy. The rest of this page explains why it takes place and how to make sure it does not — useful if you are reading ahead of time.
Two fillers, two tanks: AdBlue in a diesel car
Diesel goes to the motor — yet many modern diesels seen around Persondy and Gwyddon hold a second liquid as well. The exhaust, not the engine, is where AdBlue goes: sprayed into the fumes to clean it, from a separate tank.
Separate tanks, different fillers. Other motors put the AdBlue filler in the boot or under the bonnet; a lot more place both together behind one flap. The diesel side is topped up at the petrol pump all the time. Someone who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less often. It's in the gap that the error lives.
AdBlue in your diesel tank in Persondy: how it takes place
It's seldom carelessness. Three things tend to line up.
To start with, the warning. Low AdBlue brings a warning from the vehicle, and running out means limp mode — hence a hurried top-up, maybe before work off Maple Terrace, or at Market Tavern on the way home after work.
The old car's filler is where your hand goes — yet a rental car, a new car or a company car puts the fillers somewhere else. That is a second thing: an unfamiliar car.
No part stops the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Persondy or out in Celynen.
How to tell the AdBlue filler from the diesel one
Before you tip anything, whether on a driveway in Chapel of Ease or a forecourt around Persondy, check these. They take a few seconds.
- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap normally is not. Read it rather than going by position.
- On plenty of cars, the size tells: AdBlue gets the smaller filler neck.
- Check inside the fuel flap: plenty of cars have a label there saying which fuel goes where.
- The handbook. If your filler isn't by the diesel cap, it is in the boot or under the bonnet, and the handbook says which.
- Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Newbridge.
How to top up without AdBlue in your diesel tank
When the light goes on, anywhere across Caerphilly, use this routine.
- Stop on level, engine off, with time to spare — not hurried on the side of Acacia Terrace.
- Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — after you have found your filler and read the cap.
- Both behind a single flap? So make sure the lid on the diesel filler is still shut ahead of raising the bottle.
- Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
- Close the cap, then look again — confirm the diesel cap stayed shut throughout. Only then, start the car.
If at stage two or three you find you have already poured into the diesel side, stop there. Never go on to step five.
AdBlue in your diesel tank already, in Persondy?
Then the order of things is short. Don't start the engine. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. 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.
If you're on a forecourt, whether it's the Texaco or the Sainsbury's, ask the staff to help push the vehicle away from the petrol pump. Leave it where it is if you're on your own drive in Persondy.
Already run? Pull over once it's sensible, then turn off. Leave the M4 — under 10 miles out of Persondy — at the first exit. About how far did it go? Crossing Persondy is less work than a run of under 10 miles towards Newport, so tell us.
What happens when our engineers turn up in Persondy
Outside the local primary school, near St Luke's Church or on your own driveway: wherever the vehicle has stopped, our technicians come to it. We ask what was put in, about how much, and whether it has run, because those answers determine this work and the quote. No one sets off until you've had our quote over the phone.
The system is then cleaned thoroughly, once that tank is cleared. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of it washes away unaided. That is why it counts more. After the filter has been cleaned — or replaced, if required — clean diesel goes in, and then your car gets tested. We do not go until it has been fired up and is running smoothly.
If the motor hasn't run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. Your insurer will ask for an engineer's report and the VAT invoice, and you get both once the job is done. Payment comes on the day, with no deposit. It's worth checking your policy as the van travels to you: misfuelling cover is included with plenty of policies.

AdBlue drains round Persondy, and Caerphilly beyond
Persondy is a residential suburb, and the teams that cover it also work the places near it, Llanfach and High Meadow among them, across the NP postcode area. Quote a postcode that starts NP11 5, and the van gets there fastest.
The vehicle does not need to shift. Our technicians drain it where it is — a side street close to Welsh Calvinistic Methodist Chapel, a lay-by on the way to Caetwmpyn Park, a driveway. Tricky to pin down, like the back of Abercarn Library? By a border? Asking beats assuming, so phone.
