How It Happens and How to Avoid It: AdBlue in a Diesel Tank in Crossley Hill
Keep the engine and ignition off then call 0333 366 0103 now — reading can wait if AdBlue is already in your diesel tank. In Crossley Hill, finding it before your engine turns usually means a drain and a thorough flush on the spot. The remainder of this page explains why it occurs and how to make sure it does not — handy if you're reading before it has happened.
Why does AdBlue in a diesel motor need its own filler?
Plenty of newer diesels in Knowl, like those in Crossley Hill, run on two liquids; your motor takes just your diesel. The exhaust, not the motor, is where AdBlue goes: sprayed into the gas to clean them, from a separate tank.
Every tank has a filler of its own. Under one flap, side by side: that's the layout on many cars. On others, AdBlue's filler is beneath the bonnet or in your boot instead. Diesel gets filled on every forecourt visit, again and again. Someone who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less often. That gap is where the mistake lives.
AdBlue in your diesel tank around Crossley Hill: how it happens
Three things tend to line up, and carelessness is rarely one of them.
The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off North Place before work, or in the car park outside Saville Arms on the way home.
The old car's cap is where your hand goes — but a rental car, a new car or a company car keeps the fillers somewhere else. That is the second factor: a new vehicle.
Lastly, the spout goes in: a diesel filler or AdBlue filler, it goes in just as readily, and once the pour starts, no part stops it. Kitson Hill or the middle of Crossley Hill: it takes the same few seconds either way.
How to tell the AdBlue filler from the diesel one
Be it a Crossley Hill forecourt or a driveway out in Stocks Bank, spend a few seconds on these before anything is poured in.
- Blue and marking: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits.
- On plenty of motors, size gives it away: AdBlue gets the smaller filler neck.
- A label inside the fuel flap often says which fuel goes where, on many vehicles. Look for it.
- Can't find it next to your diesel inlet? Then check below the bonnet or in your boot — the handbook says where.
- Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Mirfield.
How to top up without AdBlue in your diesel tank
When the light comes on, wherever across West Yorkshire, use this routine.
- Turn off after you park — level ground, engine stopped, and never in a rush beside Old Bank Road on the verge.
- Silly as it sounds, saying "AdBlue" out loud while you unscrew the cap works — after you've located your filler and read the cap.
- The two under a single flap? Then make sure the lid on your diesel side stays closed ahead of lifting the bottle.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Close the cap and check once more. Make sure the diesel cap was never opened. Only then start the vehicle.
Stop there if you find, at stage two or three, that you've already poured into your diesel side. Do not go on to step five.
Crossley Hill: already put AdBlue in the diesel tank?
Short order, then. Top of that: the engine stays off. On many diesels the ignition alone runs the fuel pump, so don't switch the vehicle on. Thinning it with more diesel fails, since AdBlue sinks to the base instead of blending — and that is where the fuel is pulled from.
Ask the attendants to help push your car clear of the petrol pump if you're on a forecourt — the Shell, the Morrisons or somewhere else. Your own driveway around Crossley Hill is where it should stay.
When your engine has been run by now, stop safely then turn the car off. Crossley Hill sits under 3 miles from the M62; on it, take the next exit. Distance counts — a short hop across Crossley Hill makes a smaller job than heading under 10 miles to Bradford — so tell us roughly how far it went.
Crossley Hill: what happens when our technicians arrive
Outside Crossley Fields Junior and Infant School, close to Wellhouse Moravian Church or on your own driveway: wherever the vehicle has stopped, our technicians come to it. Those answers settle the work and our price, and so our technicians ask what went in, about how much, and if it has run. You get that price by phone, before anybody heads out.
Next: draining, then a full flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why that matters more here than with petrol. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Then our engineers fire it up and check it runs properly before we go.
Unrun vehicles usually need a half-hour job from the moment we arrive. The kit is safe on a busy forecourt, and hushed enough for a residential street after dark. Your insurer will ask for the engineer's report and your VAT invoice, and you get both once this job is done. Payment is on the day, with no money upfront. Before we get there, have a look at your insurance documents; many include cover for misfuelling.
