Preventing AdBlue in a Diesel Tank in Edwardsville: Why It Occurs
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 your motor has not turned, it's emptied and thoroughly cleaned where the vehicle sits in Edwardsville. Not happened yet? Below, the rest of the page covers the why it happens and the ways to prevent it altogether.
Two fillers, two tanks: AdBlue in a diesel vehicle
Many newer diesels on the roads round Edwardsville and Treharris carry two liquids, not one. Diesel goes to the engine. AdBlue's own tank keeps it, and from there it goes to your exhaust, and there spraying cleans the fumes.
Each tank has its own filler. Many of motors share a single flap for both, while some move the AdBlue filler to the boot or under the bonnet. Topping up your diesel side at the petrol pump happens all the time. Much less often, the AdBlue side is topped up — mostly from a bottle, by someone working out where it goes. Mistakes happen in that gap between them.
AdBlue in the diesel tank around Edwardsville: how it takes place
Rarely is it carelessness: normally three things line up.
Hurry comes from the warning. The car tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a drive off Cardiff Road, or heading home in the car park at Great Western Hotel.
New-to-you vehicles come second, as well. Hire cars, new vehicles and company motors place their fillers in new places, and the hand reaches for the cap it used on the old one.
Nothing stops the tip after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Craig Berthlwyd or the middle of Edwardsville: it is the same few seconds in both.
Which filler is for AdBlue, and which for diesel?
Check these first, at a forecourt in Edwardsville or a driveway out in Pentwyn Berthlwyd. Seconds, that's all.
- Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position.
- On plenty of motors, the size gives it away: AdBlue has the smaller filler neck.
- The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
- The handbook. If the filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which.
- 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 outside Quakers Yard.
AdBlue top-ups that never reach your diesel tank
The day the light goes on, anywhere across Merthyr Tydfil, follow this routine.
- Switch off once parked — level ground, engine stopped, and never rushed by Windsor Road on the verge.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
- Leave your diesel cap on. If both sit under one flap, check your 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 the own spout.
- Shut the cap, then check again — confirm the diesel cap remained closed the whole time. After that, start the car.
Find at step two or three that it's already gone into your diesel side? Then stop just there. Skip stage five entirely.
Already put AdBlue in your diesel tank in Edwardsville?
Brief order, then. Top of it: the engine stays unstarted. The fuel pump runs on plenty of diesels the moment the ignition is switched on — and so leave it off. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is pulled from.
If you are on a forecourt, whether it is the Gulf Treharris Service Station or the Texaco, ask the staff to help push the car clear of the petrol pump. Leave it where it is if you are on your own drive around Edwardsville.
Where the motor has been run by now, pull over somewhere safe then turn it off. On the M4, under 10 miles from Edwardsville, that means the next exit. Mileage matters — a quick hop across Edwardsville makes a smaller job than heading under 15 miles towards Cardiff — so say about how far it went.
What happens when we arrive in Edwardsville
Anywhere the car has stopped, whether outside the local primary school, near English Congregational Church or at home, our van comes to it. Which liquid went in, the quantity, and whether it ran: our engineers ask because those answers decide both work and quote. No one heads out before you have heard the price over the phone.
The system is then cleaned thoroughly, after that tank is emptied. Much more than with petrol, it counts with AdBlue: the crystals form, some metals are attacked, and none of that clears away unaided, no matter how long it is left. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Your engine is fired up next and tested to confirm it runs properly, all before our technicians head off.
If the engine hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark. Nothing in advance; you settle up on the day. At the end, a VAT invoice and a report from the engineer are handed to you for the insurer. It's worth looking at your policy while we travel to you: misfuelling cover comes with plenty of policies.

The car doesn't need to shift. A drive, a lay-by on the way to Treharris Park, a side street close to The Church of Christ Evangelical Baptist Church: our technicians drain the car where it sits. Tricky to pin down, like the back of Saint Matthias Church Treharris? Close to a county line? Checking beats assuming, and so phone.
