Avoiding AdBlue in a Diesel Tank in Llancayo: Why It Happens
AdBlue already in the diesel tank? In that case set this page aside for now, keep your ignition and engine off, and call 0333 366 0103. Normally, if your engine hasn't turned, it's emptied and thoroughly purged where the vehicle is in Llancayo. The rest of this page covers why it happens and how to make sure it does not — handy if you're reading before it has happened.
AdBlue in a diesel vehicle: two tanks, two fillers
Diesel goes to the engine — but plenty of current diesels seen round Llancayo and Gwehelog carry another liquid too. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.
There's a filler for each tank. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel gets filled on each filling station call-out, again and again. Someone who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less frequently. Mistakes happen in the gap between them.
How AdBlue in your diesel tank occurs in Llancayo
Rarely is it carelessness: usually three things coincide.
Hurry follows from the warning. Your car tells you as AdBlue runs low, and a dry tank puts it into limp mode — so the top-up happens quickly, before work on a driveway off B4598, or on the way home in the car park at the pub in the village.
The old car's cap is where your hand reaches — yet a rental car, a new car or a company car puts the fillers elsewhere. That's a second thing: a strange car.
No part stops the pour after it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes seconds, be it out in Rhadyr or right in the centre of Llancayo.
Which filler is for AdBlue, and which for diesel?
Be it a Llancayo forecourt or a drive over in Gwehelog Common, spend a few seconds on these before any goes in.
- Where it sits misleads; the cap does not. AdBlue caps are often blue or bear the name "AdBlue" — diesel caps normally do not.
- The size. On many cars the AdBlue filler neck is the smaller of the two.
- Look inside your fuel flap: many vehicles have a label there showing which fuel goes where.
- The handbook. If the filler isn't by your diesel cap, it is in your boot or under the bonnet, and the handbook says which.
- The previous driver will know. Check as you pick up a rental or company car — from Pontypool and New Inn's car park, say — not when the light appears.
Keeping AdBlue out of your diesel tank when you top up
The day the light goes on, wherever in Monmouthshire, follow this routine.
- Turn off after you park — level ground, engine off, and not in a rush by Private at the roadside.
- Locate the AdBlue filler, check the cap, and speak the word "AdBlue" out loud as you unscrew it. It sounds daft. It does the trick.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave it on.
- Stop when that tank fills or the bottle runs dry; before that, pour gently through its built-in spout.
- Shut the cap, and check again — confirm your diesel filler stayed shut the whole time. Only then, start your car.
Discover at the second or third step that AdBlue went in the wrong tank? That is where you stop. Leave out step five entirely.
Put AdBlue in the diesel tank around Llancayo already?
Short list, then. Top of that: the engine stays off. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Diluting it with extra diesel fails, since AdBlue sinks to the bottom rather than blending — and that is where your fuel is drawn from.
At a forecourt — BP, Gulf or another — the attendants will normally help roll your car away, if you ask. If you're on your own driveway around Llancayo, leave the vehicle where it stands.
When the engine has run by now, pull over somewhere safe then switch it off. The next junction means where to come off if you're on the M4, under 10 miles from Llancayo. Tell us roughly how far it went: a run towards Newport, under 15 miles away, is a bigger job than a short hop across Llancayo.
When we get there around Llancayo, what takes place?
We come to the car wherever it has stopped, whether that is outside the local primary school, near St. Davids or on your own driveway. Our engineers ask what was put in, about how much, and whether it's run, since those answers decide the work and our quote. That quote comes on the call, ahead of any van leaving.
Next: a drain, then a thorough flush of the whole system. More than with petrol, it counts here: the crystals build up, certain metals are attacked, and nothing clears away on its own, no matter how long it is left. Once the fuel filter is cleaned — or replaced, where required — fresh diesel goes in, and finally the car is tested. After that our technicians fire it up and check it runs properly before we leave.
Most jobs are finished in about half an hour after we get there, provided the engine has not run — and the pumps our technicians use are safe on a busy forecourt and quiet after dark outside a house. The insurer will ask for an engineer's report and your VAT invoice, and you get both once this job is done. Payment comes on the day, with no money upfront. It's worth looking at your policy while we travel to you: misfuelling cover is included with many policies.

Shifting the vehicle is not needed. A driveway, a lay-by on the way to Llancayo Wood, a side street near Usk Castle: we drain the vehicle where it sits. Awkward to explain, like the back of St David Lewis & St Francis Xavier Parish Church? Close to a county line? Asking beats guessing, and so ring.
