AdBlue in a Diesel Tank in Upper Forge: How It Occurs and How to Avoid It
Leave your motor and ignition off and phone 0333 366 0103 first — reading can wait if AdBlue is already in the diesel tank. Normally, if your motor has not run, it's drained and thoroughly cleaned where your car sits in Upper Forge. The rest of this page covers why it takes place and how to make sure it does not — handy if you're reading ahead of time.
AdBlue in a diesel motor, and its separate tank
Not one fluid but two: that is what plenty of newer diesels around Upper Forge and Penydre carry, with diesel feeding the engine. Your exhaust, not the motor, is where AdBlue ends up: dosed into the gas to clean it, from its own tank.
Each tank comes with a filler of its own. Some vehicles put the AdBlue filler in your boot or under the bonnet; a lot more place both side by side under one flap. Diesel gets filled on every filling station visit, week in, week out. Seldom filled, AdBlue normally comes out of a bottle, poured by someone who has to stop and think what filler it needs. That gap is where the slip lives.
How AdBlue in the diesel tank takes place around Upper Forge
Carelessness rarely explains it. What does is three things lining up at once.
To start with, the warning. Low AdBlue triggers a message from the car, and letting it run out leads to limp mode — so a hurried top-up, maybe before work off Lone Road, or outside New Inn on the way home after work.
Then, your hand goes for the cap it knew on the old motor — because a hire car, a new car or a company car places the fillers somewhere your last one did not.
A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. And so the pour, after started, carries on. Faerdre or the heart of Upper Forge: it is the same few seconds in both.
The AdBlue filler and the diesel filler: telling them apart
A few seconds is all these take — so check them before you pour anything, on a driveway in Mount Pleasant or a forecourt around Upper Forge.
- Read the cap rather than going by position: AdBlue caps are regularly blue or marked "AdBlue", and diesel ones usually aren't.
- Many vehicles give AdBlue the smaller filler of the two.
- Open the flap and look for a label — plenty of motors mark what belongs in each inlet just there.
- The handbook says where it lives if your filler isn't next to your diesel cap: your boot, or under the bonnet.
- 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 outside Llansamlet.
Topping up AdBlue without it reaching the diesel tank
A routine for the day the light comes on, wherever across Swansea that is.
- Pull in somewhere level, engine off, with time in hand — never rushing on the side of Tanyrallt.
- Daft as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — once you have located the filler and read it.
- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the car on.
- Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
- Before you start the car, shut the cap and check again that your diesel cap was never came off.
Discover at the second or third step that the bottle went in the diesel filler? That's where you stop. Leave out stage five altogether.
Upper Forge: already put AdBlue in your diesel tank?
Don't start your motor: that's where the short order of things begins. Keep your ignition off as well, because on many diesels switching it on alone starts the fuel pump. Topping up with diesel won't dilute it: instead, AdBlue sinks to the bottom of your tank, just where fuel is drawn from.
If you're on a forecourt, whether it is the the nearest petrol station or the Tesco, ask the attendants to help roll your car away from the petrol pump. On your own drive in Upper Forge? So the vehicle remains put.
If the motor has already run, stop as soon as it is safe and switch off. On the M4, under 3 miles from Upper Forge, that means the next exit. Tell us about how far it went: a run towards Swansea, under 10 miles away, is a bigger job than a short hop across Upper Forge.
Upper Forge: what happens when our technicians get there
Outside the local primary school, close to Bethel Evangelical Church or on your own driveway: wherever the car has stopped, our engineers come to it. The replies decide this work and the price, so we ask what went in, about how much, and whether it's run. No one heads out before you have heard the quote by phone.
Then the tank is emptied and the system rinsed thoroughly. 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 counts more with AdBlue than with petrol. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Before leaving, our engineers fire it up and make sure that it's running properly.
Using pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs where the engine hasn't run take about half an hour once we arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way.
