Coychurch: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
AdBlue already in your diesel tank? In that case put this page down a moment, leave the ignition and engine off, then ring 0333 366 0103. Caught before your engine runs, it's normally a drain and a thorough flush, done where the vehicle is around Coychurch. If you're reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not.
AdBlue in a diesel vehicle: two tanks, two fillers
Many modern diesels around Treoes, like those in Coychurch, run on two liquids; the motor takes only your diesel. Kept in a tank of its own, AdBlue is sprayed into your exhaust gas and cleans it.
Each tank has its own filler. Other cars keep the AdBlue filler in your boot or under the bonnet; a lot of others place both together behind one flap. Filling the diesel side at the pump goes on all the time. The AdBlue side is fuelled far less commonly, usually from a bottle, and usually by somebody who has to stop and think where it goes. The slip lives in that gap.
How AdBlue in the diesel tank occurs around Coychurch
Rarely is it carelessness: normally three things coincide.
On a driveway off The Court before work, or in the car park at Prince of Wales 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 once it is gone, limp mode follows.
New-to-you vehicles are second, as well. Rentals, new cars and company cars place their fillers in new places, and habit goes for the cap used on the old one.
A spouted bottle meets no obstacle at a diesel filler any more than at an AdBlue one. And so the pour, after begun, keeps on. Shelf or the heart of Coychurch: it is the same few seconds either way.
Telling the AdBlue filler from the diesel filler
Be it a Coychurch forecourt or a driveway out in Brackla, take a few seconds on these before any goes in.
- Where it sits can mislead; the cap doesn't. AdBlue ones are often blue or carry the word "AdBlue" — diesel caps usually don't.
- The size. On many cars the AdBlue filler neck is the smaller of the two.
- A label inside the fuel flap frequently shows which fuel goes where, on plenty of cars. Look for it.
- The handbook. If your filler isn't by your diesel cap, it's in the boot or under the bonnet, and the handbook says which.
- Picking up a hire or company car, say at the car park outside Pencoed? Ask the person who drove the vehicle last before leaving, not once the light goes on.
AdBlue top-ups that never reach your diesel tank
When the light goes on, anywhere in Bridgend, follow this routine.
- Pull in on level, motor off, with time to spare — not rushing on the side of Heol-y-Capel.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
- Both under one flap? So make sure the cap on your diesel side is still closed ahead of raising the bottle.
- Slowly does it, through the bottle's own spout, until it's full or the bottle runs out.
- Only then, start the vehicle: close the cap, check again, and make sure your diesel cap was never opened.
Stop there if you find, at stage two or three, that you have already poured into your diesel side. Do not go on to step five.
Put AdBlue in the diesel tank around Coychurch already?
The short order of things, starting with not starting the motor. On plenty of diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. Diluting it with extra diesel won't work, since AdBlue settles to the base instead of blending — and that is where your fuel is sucked from.
On a forecourt — the nearest petrol station, Texaco or any other — the attendants will usually help roll the vehicle clear, if you ask. On your own drive around Coychurch? So your car stays where it is.
Already started? Stop when it's safe, then switch off. The next exit is the place to leave if you are on the M4, under 3 miles from Coychurch. Tell us about how far it went: a run towards Cardiff, under 25 miles away, is a bigger job than a short hop across Coychurch.
Our arrival around Coychurch, and what takes place next
We come to the vehicle wherever it has stopped, whether that's outside the local primary school, close to Church of St Crallo or on your own drive. Our engineers ask what went in, about how much, and if it has run, because the answers decide this work and our quote. On the call itself, you are told the price — before anything else.
Then the tank is drained and the fuel system flushed thoroughly. More than with petrol, it counts with AdBlue: the crystals form, certain metals are attacked, and none of it clears out on its own, no matter how long it sits. Testing is last: before that, clean diesel is added, and your filter is cleaned or changed if necessary. Next our technicians fire it up and check it runs correctly before leaving.
If your engine has not run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house 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. It's worth checking your insurance while we travel to you: misfuelling cover comes with plenty of policies.

AdBlue drains around Coychurch, and Bridgend beyond
Over CF postcodes, the teams that cover Coychurch — a residential suburb — work the surrounding places too, Waterton and Colychurch among them. Quickest of all: give a CF35 5 postcode to our van.
Shifting the vehicle is not necessary. Our engineers drain it where it is — a side street near Williams Memorial Hall, a lay-by on the way to Coychurch Playing Fields, a drive. Ring and ask instead of assuming if you are close to a boundary, or somewhere hard to explain, like the back of Kingdom Hall of Jehovah's Witnesses.
In short, for Coychurch motorists
Pour no AdBlue until you've read the cap. Petrol in Diesel empties it where it stands, anywhere across Bridgend, if AdBlue has gone in your diesel tank anyway — so leave the car off then phone 0333 366 0103.
