AdBlue in a Diesel Tank in Dyffryn Dowlats: How It Occurs and How to Prevent It
AdBlue already in the diesel tank? In that case put this page aside for now, leave the ignition and motor off, then phone 0333 366 0103. A drain and a full flush, carried out just where your vehicle stands around Dyffryn Dowlats, is normally all it needs when found before your motor runs. If you're reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not.
Two fillers, two tanks: AdBlue in a diesel motor
Plenty of newer diesels on the roads about Dyffryn Dowlats and Efail Isaf carry two liquids, not one. Diesel goes to the engine. Its own tank holds it, and from there it is sent to the exhaust, where spraying treats the fumes.
Different tanks, different fillers. Under one flap, side by side: that's the arrangement on many vehicles. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. Diesel goes in on every filling station call-out, week in, week out. A driver who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and far less regularly. The slip lives in that gap.
How AdBlue in the diesel tank takes place around Dyffryn Dowlats
It's seldom carelessness. Three things tend to line up.
Haste follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Coed y Broch, or on the way home in the car park outside Fagins.
The old car's filler is where the hand reaches — but a rental car, a new vehicle or a company car puts the fillers somewhere else. That's the second thing: an unfamiliar vehicle.
No part halts the tip once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it occurs in Church Village or the middle of Dyffryn Dowlats, it is the same few seconds.
Which filler is for AdBlue, and which for diesel?
A couple of seconds is all these take — so run through them before you pour anything, on a driveway in Llantwit Fardre or a forecourt in Dyffryn Dowlats.
- The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap normally isn't. Read it instead of going by position.
- On many cars, the size gives it away: AdBlue gets the smaller filler neck.
- A label inside the fuel flap often says which fuel goes where, on many vehicles. Look for it.
- In your boot or under the bonnet: that's where your filler is if it's not by your diesel cap, 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 outside Trefforest Estate.
How to top up without AdBlue in your diesel tank
A routine for the day the light comes on, wherever around Rhondda Cynon Taf that is.
- Stop on level, motor off, with time to spare — never hurried on the side of Butterfly Close.
- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Daft, perhaps, yet it works.
- The diesel cap remains on. When both sit under a flap, confirm it is shut before lifting the bottle.
- Finish once the tank is topped up or the bottle runs dry; until then, tip gently using its built-in spout.
- Before you start the vehicle, close the cap and look a second time that your diesel cap was never opened off.
Stop there if you find, at step two or three, that you have already poured into the diesel side. Stage five stays off limits.
AdBlue in your diesel tank already, in Dyffryn Dowlats?
Then the order of things is short. Do not start the motor. Don't switch the ignition on; on many diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where the fuel is sucked from — so do not top up with diesel to thin it.
Ask the staff to help roll the car away from the pump if you are at a forecourt — the Texaco, the Esso or somewhere else. At home around Dyffryn Dowlats? Then the vehicle stays put.

What happens when we get there around Dyffryn Dowlats
Our van reaches your car anywhere it has come to rest — your own driveway, beside Canolfan Hamdden Llanilltud Faerdref, or by the local primary school. Both the work and our price rest on three answers — what fluid, which amount, and whether it has run — so we ask. Nobody heads out until you've had our quote over the phone.
Then that tank is cleared and the system purged thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why that matters more here than with petrol. Testing comes last: before that, clean diesel goes in, and your filter is cleaned or changed if necessary. Before we go, our technicians fire it up and make sure that it is running correctly.
Unstarted cars usually need a half-hour visit after the moment we arrive. The equipment is fine on a busy forecourt, and hushed enough for a residential street late at night. Your insurer will ask for an engineer's report and your VAT invoice, and you get both once this job is done. Payment comes on the day, with no deposit. Before we get there, take a look at your policy; many carry cover for misfuelling.
