Swffryd: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
Keep your engine and ignition off and phone 0333 366 0103 first — reading can wait if AdBlue is already in the diesel tank. Caught before the motor runs, it's usually a drain and a thorough flush, done where the car is in Swffryd. Not happened yet? Further down, the page explains the reasons it takes place and the how to prevent it altogether.
Two fillers, two tanks: AdBlue in a diesel car
Not one liquid but two: that is how many newer diesels near Swffryd and Rhiw carry, with diesel feeding your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Different tanks, different fillers. Plenty of vehicles have a single flap for both, while others put the AdBlue filler to the boot or under the bonnet. Filling your diesel side at the petrol pump happens all the time. A driver who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less frequently. It's in that gap that the mistake lives.
AdBlue in your diesel tank in Swffryd: how it occurs
Three things tend to line up, and carelessness is rarely one of them.
Haste comes from the warning. The car warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off Lloyd Avenue, or heading home in the car park outside Hafodyrynys Inn.
Then, your hand goes for the cap it knew on the old vehicle — since a hire car, a new motor or a company car places the fillers where your last one didn't.
Third, the bottle goes in: diesel filler or AdBlue one, it slides in as easily, and once the tip starts, no part stops it. It takes seconds, whether in Crumlin or bang in the heart of Swffryd.
The AdBlue filler and the diesel filler: telling them apart
A couple of seconds is all the checks take — so run through them before you tip anything, on a drive in Millbrook or a forecourt around Swffryd.
- Where it sits can mislead; the cap doesn't. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel ones usually do not.
- The size. On many cars the AdBlue filler neck is the smaller of the two.
- The flap. Look inside your fuel flap for a label. Plenty of cars say there which fuel goes where.
- Can't see it next to your diesel inlet? In that case look beneath the bonnet or in the boot — the owner's manual will say which.
- The previous driver will know. Ask when you collect a rental or company car — from Llanhilleth's car park, perhaps — not once the light comes on.
How to top up without AdBlue in your diesel tank
When the light goes on, wherever in Blaenau Gwent, follow this routine.
- Turn off after you park — flat ground, engine stopped, and not rushed beside Walters Avenue at the roadside.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
- Both behind a single flap? Then confirm the lid on your diesel side stays shut ahead of raising the bottle.
- Gently does it, through the bottle's own spout, until it is full or the bottle is empty.
- Close the cap, and look again — confirm your diesel filler stayed closed throughout. Only then, start the car.
Discover at the second or third stage that AdBlue went in the wrong tank? That is where you stop. Skip stage five altogether.
Swffryd: already put AdBlue in your diesel tank?
Brief order, then. First: your motor stays unstarted. The fuel pump starts on many diesels the moment the ignition goes on — so leave it off. Filling up with diesel will not dilute it: instead, AdBlue drops to the base of that tank, just where the fuel is drawn from.
If you are on a forecourt, whether it's the Texaco or the another forecourt nearby, ask the staff to help push the car away from the petrol pump. Your own drive in Swffryd is where it stays.
Already started? Pull over when it is sensible, then switch off. Swffryd lies under 10 miles from the M4; on it, use the next exit. Distance counts — a short hop across Swffryd is a smaller job than driving under 10 miles to Newport — so tell us roughly how far it went.
What happens when we get there in Swffryd
Our van comes to the car wherever it stopped — your own driveway, near Swffryd Community Centre, or by the local primary school. What liquid got in, the quantity, and if it ran: our engineers ask because those answers decide the work and price. No one sets off until you have heard the price by phone.
Then the tank is emptied and your system purged thoroughly. More than with petrol, it counts with AdBlue: crystals build up, certain metals are attacked, and nothing clears away on its own, however long it is left. Filter cleaned or, if it must be, swapped; clean diesel in; and then a check of your vehicle. Then our engineers fire it up and confirm it runs correctly before we go.
Most jobs are done in about half an hour once we get there, as long as your motor hasn't run — and the pumps our engineers use are fine on a busy forecourt and quiet at night beside a house. Payment happens on the day, not upfront, and you are given the paperwork your insurer wants: an engineer's report and a VAT invoice. Many insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way.
