AdBlue in a Diesel Tank in Abernant: Why It Occurs and How to Prevent It
AdBlue already in your diesel tank? In that case set this page down a moment, leave your ignition and motor off, then ring 0333 366 0103. Normally, if the motor has not turned, it's drained and fully purged where the car sits in Abernant. If you're reading before it has happened, the rest of this page is about why it happens and how to make sure it doesn't.
Why does AdBlue in a diesel motor need its own filler?
Plenty of modern diesels on the roads about Abernant and Trecynon carry two liquids, not one. Diesel goes to 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's a filler on every tank. Some vehicles put the AdBlue filler in the boot or under the bonnet; plenty of others have the two together behind one flap. Diesel gets filled on each forecourt visit, again and again. A driver who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and much less often. That gap is where the error lives.
How does AdBlue in your diesel tank take place around Abernant?
Carelessness rarely explains it. Instead is three things lining up at once.
To start with, the warning. Low AdBlue triggers a warning from the vehicle, and letting it run dry means limp mode — so a hurried top-up, maybe before work off Forge Place, perhaps at Pickled Pepper on the way home after work.
The old car's cap is where your hand goes — yet a rental car, a new motor or a company car puts the fillers somewhere else. That is a second factor: an unfamiliar vehicle.
Nothing halts the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes seconds, whether in Robertstown or bang in the centre of Abernant.
How to tell the AdBlue filler from the diesel one
Check these before pouring, on a forecourt in Abernant or a driveway out in Aberaman. A few seconds, no more.
- Read the cap instead of going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel ones usually aren't.
- The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
- Open the filler flap and check for a label — many cars mark what belongs in which inlet just there.
- The handbook says where it is if your filler is not next to your diesel cap: the boot, or under the bonnet.
- Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Aberdare.
AdBlue top-ups that never reach your diesel tank
When the light goes on, wherever across Rhondda Cynon Taf, use this routine.
- Turn off once parked — level ground, engine off, and never in a rush by Fothergill Street at the roadside.
- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Silly, yes, yet it does the trick.
- The diesel cap stays on. Where both share a flap, make sure it's shut before the bottle comes up.
- Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
- Close the cap and check again. Make sure your diesel cap was never opened. Only then start your car.
If at stage two or three you find you have already poured into your diesel side, stop there. Do not go on to step five.
Put AdBlue in the diesel tank around Abernant already?
Short list, then. First: your motor remains unstarted. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from.
At a forecourt — Tesco, Texaco or another — the attendants will usually help push the car clear, if you ask. Your own driveway in Abernant is the place it should stay.
Where the engine has been run by now, pull over somewhere safe then switch it off. The next exit means where to come off if you're on the M4, under 15 miles from Abernant. About how far did it go? Crossing Abernant is smaller work than a trip of under 25 miles to Cardiff, so say.
When our technicians get there in Abernant, what happens?
By the local primary school, near Sobell Leisure Centre or on your own driveway: wherever your car has stopped, our engineers come to it. Those replies decide the work and the price, and so our engineers ask what was put in, roughly how much, and whether it has run. No one heads out before you have had our quote by phone.
The fuel system is then flushed thoroughly, after your tank is emptied. 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. The filter flushed or, if needed, replaced; fresh diesel in; and then a check of the car. Before leaving, our engineers fire it up and confirm that it's running correctly.
With pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs where the motor has not run take about half an hour after our technicians arrive. Payment happens on the day, not upfront, and you are given the documents an insurer wants: an engineer's report and a VAT invoice. Misfuelling cover is part of plenty of insurance policies — so make use of the wait to check yours.
