Pontnewynydd: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
Stop here for a moment when your diesel tank already has AdBlue in it: ignition off, engine off, then phone 0333 366 0103. Around Pontnewynydd, finding it before your engine runs usually means draining and a thorough flush on the spot. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not.
Why does AdBlue in a diesel motor need its own filler?
Diesel goes to the engine — but plenty of current diesels seen around Pontnewynydd and Pentrepiod carry another liquid too. Your exhaust, not the engine, is where AdBlue goes: sprayed into the gas to clean it, from a separate tank.
Each tank has its own filler. Some cars put the AdBlue filler in your boot or under the bonnet; a lot more place the two together behind one flap. Diesel gets filled on each forecourt visit, again and again. Someone who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and far less often. That gap is where the slip lives.
How does AdBlue in your diesel tank take place in Pontnewynydd?
Three things tend to come together, and carelessness is seldom one of them.
On a driveway off Estate Road before work, or in the car park outside Forge Hammer heading home: that's where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low your car warns you, and if it is gone, limp mode kicks in.
New-to-you cars come next, as well. Rentals, new motors and company vehicles put their fillers differently, and habit reaches for the cap used on the old one.
Nothing stops the tip 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 Pontnewynydd or out in Mount Pleasant.
Which filler is for AdBlue, and which for diesel?
A few seconds is all these take — so run through them before you pour anything, on a driveway in Charlesville or a forecourt in Pontnewynydd.
- Read the cap instead of going by position: AdBlue ones are often blue or marked "AdBlue", and diesel ones usually aren't.
- Many vehicles fit AdBlue the smaller filler of the two.
- Lift the filler flap and look for a label — plenty of cars mark what goes in each filler right there.
- In the boot or under the bonnet: that's where your filler sits if it is 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 — if you collect a hire or company car from somewhere like the car park at Pontypool and New Inn.
How to top up without AdBlue in the diesel tank
When the light comes on, anywhere across Torfaen, use this routine.
- Stop on level, motor off, with time to spare — never rushing on the side of Hanbury Road.
- Locate the AdBlue filler, check the cap, and say the word "AdBlue" aloud while you unscrew it. It seems daft. It works.
- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave it on.
- Finish when that tank fills or the bottle is empty; before that, pour gently through its built-in spout.
- Shut the cap, and look again — confirm the diesel filler stayed closed throughout. After that, start the vehicle.
Spot at stage two or three that it's already gone into your diesel side? So stop just there. Stage five is out.
Put AdBlue in your diesel tank in Pontnewynydd already?
What follows is a short order of things, beginning with not starting the motor. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is sucked from.
Ask the staff to help roll your car clear of the petrol pump if you're on a forecourt — the Texaco, the another forecourt nearby or anywhere else. On your own drive around Pontnewynydd? Then the car stays where it is.
Already started? Pull over once it's safe, then turn off. Pontnewynydd lies under 10 miles from the M4; there, take the first exit. A short hop across Pontnewynydd is a smaller job than a run towards Newport, under 10 miles away, so tell us about how far it went.
Pontnewynydd: what takes place when we turn up
Wherever the car has stopped, be it outside the local primary school, beside Ebenezer Centre or on your own drive, the van travels to it. Those replies settle the work and our price, and so we ask what went in, roughly how much, and if it's run. The price is given on the call, before any van leaves.
The system is then purged thoroughly, after that tank is emptied. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why that matters more with AdBlue than with petrol. A test comes at the end: before that, clean diesel goes in, and your filter is flushed or replaced as needed. Your engine is fired up next and tested to confirm it runs smoothly, all before we go.
If your engine hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. Paying happens on the day, not upfront, and you are given the documents your insurer wants: an engineer's report and a VAT invoice. Wrong-fuel cover is part of many insurance policies — so use the wait to check yours.
