Avoiding AdBlue in a Diesel Tank in Gwernydd: Why It Occurs
Keep the motor and ignition off then ring 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank. Caught before the engine runs, it's usually a drain and a thorough flush, done where the car is around Gwernydd. Reading in advance? Then the rest explains how it happens and what to stop it ever happening.
Two fillers, two tanks: AdBlue in a diesel motor
Diesel goes to your engine — yet plenty of newer diesels seen about Gwernydd and Pant hold another fluid too. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Each tank has one filler of its own. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. The AdBlue side is topped up far less regularly, usually from a bottle, and normally by a person who has to stop and think where it goes. The error lives in that gap.
How AdBlue in your diesel tank happens in Gwernydd
Rarely is it carelessness: normally three things coincide.
Haste comes from the warning. The vehicle 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 driveway off Gwernydd, or on the way home in the car park outside Douglas Arms.
Then your car is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and your hand hits for the cap it would have used on the old one.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip once it has started. Whether it occurs in Gerlan or the middle of Gwernydd, it's the same few seconds.
Telling the AdBlue filler from your diesel filler
Before you tip anything, whether on a drive in Penybryn or a forecourt around Gwernydd, check these. They take a few seconds.
- Check the cap instead of going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps normally aren't.
- On many vehicles, the size gives it away: AdBlue gets the smaller filler neck.
- The flap. Look inside your fuel flap for a label. Many motors say there which fuel goes where.
- Can't find it beside your diesel inlet? Then check beneath the bonnet or inside your boot — the handbook will say which.
- Ask the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside Bangor (Gwynedd).
How to top up without AdBlue in the diesel tank
The day the light comes on, wherever across Gwynedd, follow this routine.
- Turn off after you park — level ground, engine off, and not rushed beside Ciltwllan on the verge.
- Silly as it sounds, speaking "AdBlue" out loud as you unscrew the cap works — after you've located your filler and read the cap.
- The diesel cap stays on. Where the two share a flap, confirm it is closed before the bottle comes up.
- Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
- Only after that, start the car: close the cap, check again, and make sure your diesel cap was never opened.
If at step two or three you find you have already poured into your diesel side, stop there. Do not go on to stage five.
Gwernydd: already put AdBlue in the diesel tank?
Short order, then. First: the engine stays off. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Diluting it with extra diesel won't work, because AdBlue sinks to the bottom instead of mixing — and that is where your fuel is pulled from.
At a forecourt — EG Garages, Calor or another — the attendants will normally help push the car away, if you ask. If you're on your own driveway around Gwernydd, leave the vehicle where it is.
Where your engine has been run by now, stop safely and switch the car off. Gwernydd sits under 50 miles from the Moreton Spur; there, use the first exit. About how far did it go? Crossing Gwernydd is smaller work than a trip of under 5 miles towards Bangor, and so say.
Our arrival around Gwernydd, and what takes place next
Outside the local primary school, near Christ Church or on your own driveway: wherever your car has stopped, our technicians come to it. The answers determine this work and the price, and so our technicians ask what was put in, about how much, and whether it's run. The quote is given on the call, ahead of any van leaving.
Next: a drain, then a full flush of the whole system. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and neither clears away unaided. That is why it counts more. Filter flushed or, where needed, swapped; fresh diesel in; then a check of the car. Before leaving, our technicians start the car and make sure that it is running correctly.
With pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs where your engine hasn't run need about half an hour after our technicians are there. Your insurer will ask for the engineer's report and the VAT invoice, and you get both once the job is done. Payment comes on the day, with no money upfront. Misfuelling cover is part of plenty of insurance policies — so use the wait to check yours.
