How It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Rassau
Leave the motor and ignition off and ring 0333 366 0103 now — reading can wait if AdBlue is already in the diesel tank. Caught before the motor runs, it is usually a drain and a thorough flush, done where the vehicle is around Rassau. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't.
AdBlue in a diesel car, and its separate tank
Plenty of current diesels on the roads around Rassau and Glyncoed carry two liquids, not one. Diesel goes to the engine. AdBlue's own tank holds it, and from there it goes to the exhaust, where spraying treats the fumes.
Separate tanks, different fillers. Under one flap, side by side: that is the arrangement on many motors. Elsewhere, AdBlue's filler is under the bonnet or in the boot instead. Diesel goes in at each forecourt call-out, week in, week out. The AdBlue side is topped up far less often, normally from a bottle, and normally by somebody who has to stop and think where it goes. The error lives in that gap.
How AdBlue in the diesel tank occurs in Rassau
Seldom is it carelessness: normally three things line up.
On a drive off Heads of the Valleys Road before work, or in the car park outside the pub in the village on the way home: that's where the hurried top-up takes place. Why the rush? As AdBlue gets low your car warns you, and if it is empty, limp mode follows.
The old car's filler is where the hand goes — yet a rental car, a new car or a company car keeps the fillers somewhere else. That is a second factor: an unfamiliar vehicle.
No part stops the pour once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Carmeltown or the heart of Rassau: it takes the same few seconds either way.
Which filler is for AdBlue, and which for diesel?
A couple of seconds is all these take — so run through them before you tip anything, on a driveway in Beaufort or a forecourt in Rassau.
- Check the cap rather than going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel ones normally aren't.
- The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two.
- Open the flap and look for a label — plenty of cars show what goes in which inlet just there.
- Can't see it next to your diesel filler? Then check beneath the bonnet or inside the boot — the handbook says where.
- Whoever had it before will know. Check when you pick up a rental or company car — from Ebbw Vale Town's car park, say — not once the light comes on.
How to top up without AdBlue in your diesel tank
A routine for the day the light comes on, wherever around Blaenau Gwent that is.
- Not in a rush on the side of Stonebridge Road, not on a slope, not with your motor running: park and switch off properly.
- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, perhaps, yet it works.
- Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
- Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start your car.
If at step two or three you find you have already poured into the diesel side, stop there. Step five stays out.
Rassau: already put AdBlue in the diesel tank?
Don't start the motor: that's where the short order of things starts. The fuel pump starts on plenty of diesels the moment your ignition goes on — so leave it off. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is drawn from — so do not top up with diesel to dilute it.
At a forecourt — Morrisons, Tesco or another — the attendants will usually help push your car away, when you ask. Your own drive in Rassau is where it stays.
When your motor has run by now, stop safely then switch the vehicle off. The next exit is where to leave when you're on the M4, under 25 miles from Rassau. Tell us about how far it went: a run towards Newport, under 25 miles away, is a bigger job than a short hop across Rassau.
When our engineers get there around Rassau, what takes place?
Our van reaches your car wherever it stopped — your own driveway, near Rassau Resource Community Centre, or outside the local primary school. Which liquid was put in, the quantity, and whether it ran: our technicians ask since the answers decide both work and price. No one heads out until you have heard our quote over the phone.
After that: a drain, then a thorough flush of the whole system. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and neither washes away unaided. That is why it counts more. The filter flushed or, where needed, replaced; fresh diesel in; and then a check of your car. Before we leave, our technicians start it and check that it's running smoothly.
Most jobs are done in roughly half an hour once our technicians arrive, provided your motor has not run — and the pumps our engineers use are safe on a busy forecourt and quiet after dark outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth looking at your policy while we travel to you: misfuelling cover is included with many policies.

There's no need to move the car. Wherever it sits — beside Carmel Independent Chapel, on a lay-by heading to Beaufort Hill Ponds & Woodlands, at home — that is where it is cleared. If you're close to a border, or somewhere hard to describe like the back of St David's Church, ring and ask instead of assuming.
