Gilfach Goch: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?
If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and the ignition off then phone 0333 366 0103. Usually, when the motor hasn't turned, it's emptied and thoroughly purged where the car sits around Gilfach Goch. Not happened yet? Below, the rest of the page explains the reasons it happens and the ways to avoid it for good.
Two fillers, two tanks: AdBlue in a diesel car
Plenty of modern diesels on the roads round Gilfach Goch and Penrhiwfer carry two liquids, not one. Diesel goes to your engine. Your exhaust, not your engine, is where AdBlue ends up: sprayed into the fumes to fresh them, from a separate tank.
Each tank has one filler of its own. Some motors keep the AdBlue filler in your boot or under the bonnet; plenty more have the two together behind one flap. Topping up your diesel side at the petrol pump happens all the time. Far less often, the AdBlue side is topped up — mostly from a bottle, by someone thinking about where it goes. The mistake lives in that gap.
Gilfach Goch: how AdBlue in the diesel tank takes place
Rarely is it carelessness: usually three things coincide.
First, the warning. Low AdBlue brings a message from your car, and running out leads to limp mode — so a hurried top-up, maybe before work off Abercerdin Road, or at the pub in the village on the way home that evening.
Then, your hand reaches for the cap it knew on the old vehicle — because a rental car, a new vehicle or a company car places the fillers where your last one did not.
Lastly, the bottle goes in: a diesel filler or AdBlue one, it goes in as readily, and after the pour starts, no part halts it. It takes a few seconds, be it in Evanstown or right in the heart of Gilfach Goch.
How to tell the AdBlue filler from the diesel one
Look at these first, on a forecourt in Gilfach Goch or a driveway over in Williamstown. Seconds, that's all.
- Where it sits misleads; the cap does not. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel caps usually don't.
- On plenty of motors, size gives it away: AdBlue gets the smaller filler neck.
- A label inside the fuel flap frequently shows which fuel goes where, on many cars. Look for it.
- The handbook. If your filler is not by your diesel cap, it is in the boot or under the bonnet, and the handbook says which.
- Whoever had it before knows. Check when you pick up a hire car or fleet car — from Tonypandy's car park, perhaps — rather than when the light appears.
Keeping AdBlue out of the diesel tank when you top up
Anywhere around Bridgend the light comes on, this is a routine for that day.
- Turn off once parked — flat ground, motor off, and never in a rush by Kenry Street at the roadside.
- Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap works — once you've located your filler and read the cap.
- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave it on.
- Gently does it, through the bottle's own spout, till it's full or the bottle runs out.
- Close the cap and check once more. Make sure the diesel cap was never opened. Only then start your car.
Discover during the second or third stage that the bottle went into the diesel filler? That is where you stop. Never carry on to step five.
Already put AdBlue in your diesel tank in Gilfach Goch?
Do not start your motor: that is how the short order of things begins. On many diesels the ignition alone runs the fuel pump, so don't switch the vehicle on. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where the fuel is drawn from — so don't top up with diesel to thin it.
The attendants at Shell, Gulf or another forecourt will normally lend a hand to push the vehicle clear when asked. At home around Gilfach Goch? So the vehicle stays where it is.
Stop as soon as it is safe and switch off, if your motor has already run. Gilfach Goch sits under 10 miles from the M4; on it, use the next junction. Tell us roughly how far it went: a run towards Cardiff, under 25 miles away, is a bigger job than a short hop across Gilfach Goch.
Gilfach Goch: what happens when we turn up
Our technicians come to the vehicle wherever it has stopped, whether that is outside the local primary school, close to Pisgah Chapel or on your own drive. Those answers decide this work and the price, and so our engineers ask what went in, about how much, and whether it's run. On the phone call itself, you hear the price — ahead of anything else.
Emptying that tank comes next, then a thorough flush of the fuel system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. A test comes last: before that, clean diesel goes in, and the fuel filter is flushed or replaced if necessary. After that our engineers start the engine and make sure it runs smoothly before we leave.
Most jobs are done in about half an hour once our technicians arrive, provided the motor has not run — and the pumps our technicians use are safe on a busy forecourt and quiet after dark outside a house. Your insurer will ask for an engineer's report and your VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.
