How It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Tynewydd
Leave your engine and ignition off then ring 0333 366 0103 now — reading can wait if AdBlue is already in the diesel tank. Normally, when your engine hasn't run, it's drained and thoroughly flushed where the vehicle sits in Tynewydd. Reading in advance? Then the rest explains how it happens and how to prevent it ever happening.
Two fillers, two tanks: AdBlue in a diesel motor
Not one fluid but two: that's what many newer diesels around Tynewydd and Dukes Meadow run, with diesel for your motor. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
There is a filler on every tank. Many of cars have a single flap for both, while some move the AdBlue filler to the boot or under the bonnet. At the pump, your diesel side gets filled constantly. The AdBlue side is fuelled far less frequently, normally from a bottle, and usually by someone who has to stop and think where it goes. The mistake lives in that gap.
How does AdBlue in the diesel tank take place around Tynewydd?
Carelessness seldom explains it. What does is three things lining up together.
On a driveway off Tynewydd before work, or in the car park at Mountain Air Inn on the way home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low your car warns you, and if it's gone, limp mode kicks in.
Then your car is strange. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand reaches for the cap it would have used on the old one.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour after it has started. The same few seconds settle it, in the middle of Tynewydd or out in Waundeg.
Which filler is for AdBlue, and which for diesel?
Be it a Tynewydd forecourt or a driveway over in Tafarnaubach, take a couple of seconds over these before anything goes in.
- The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap usually isn't. Read it instead of going by where it sits.
- On many motors, size tells: AdBlue gets the smaller filler neck.
- Lift the flap and look for a label — plenty of motors show what goes in which filler right there.
- Cannot see it next to your diesel filler? In that case check below the bonnet or in your boot — the handbook says where.
- Picking up a hire or company car, perhaps at the car park outside Rhymney? Ask the person who drove the car last before leaving, not when the light goes on.
AdBlue top-ups that never reach the diesel tank
A routine for the day the light comes on, wherever around Blaenau Gwent that is.
- Switch off once parked — flat ground, motor stopped, and not in a rush by Trefil Road on the verge.
- Daft as it sounds, speaking "AdBlue" out loud as you unscrew the cap does the trick — after you have located your filler and read the cap.
- Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
- Finish once that tank is topped up or the bottle is empty; before that, tip gently through its own spout.
- Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the car.
Stop there if you find, at step two or three, that you've already poured into your diesel side. Step five is out.
Tynewydd: already put AdBlue in the diesel tank?
What follows is a short order of things, starting with no starting your engine. The fuel pump runs on many diesels as soon as your ignition goes on — so leave it off. Diluting it with more diesel fails, because AdBlue settles to the base instead of blending — and that's where your fuel is sucked from.
At a forecourt — Texaco, Gulf or another — the attendants will usually help roll the car away, if you ask. Leave it where it is if you are on your own drive around Tynewydd.
Stop as soon as it is safe then switch off, if your engine has already run. The next exit means the place to come off if you're on the M4, under 25 miles from Tynewydd. Tell us about how far it went: a run towards Newport, under 25 miles away, is a bigger job than a short hop across Tynewydd.
Our arrival around Tynewydd, and what happens next
Outside the local primary school, near Siloam Baptist Church or on your own driveway: wherever the vehicle has stopped, our engineers come to it. Both the work and our price rest on three replies — what fluid, what amount, and if it has run — so our engineers ask. You hear that price by phone, before anybody heads out.
After that: draining, then a thorough flush of the entire system. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither washes away by itself. Hence it counts more. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. We don't go until it has been started and is running properly.
Unrun vehicles usually mean a half-hour job from the moment we arrive. The kit is fine on a busy forecourt, and quiet enough for a residential street late at night. The insurer will ask for an engineer's report and your VAT invoice, and you get both at the end. Payment comes on the day, with no deposit. Wrong-fuel cover is included in plenty of insurance policies — so make use of the wait to look at yours.
