Woodlesford: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

Two fillers, two tanks: AdBlue in a diesel motor

Plenty of modern diesels in Rothwell, like those in Woodlesford, run on two liquids; the engine gets only your diesel. AdBlue's own tank keeps it, and from there it is sent to your exhaust, and there spraying cleans the gas.

Each tank comes with one filler of its own. Some motors put the AdBlue filler in your boot or under the bonnet; a lot of others place the two side by side behind one flap. The diesel side is filled at the pump all the time. Rarely topped up, AdBlue normally goes in from a bottle, tipped by someone who must stop and think what cap it needs. It's in that gap that the error lives.

Woodlesford: how AdBlue in your diesel tank occurs

Seldom is it carelessness: usually three things coincide.

Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Holmsley Lane, or heading home in the car park at The Two Pointers.

Then your car is new. A hire car, a new car or a company car puts the fillers where your last one did not, and the hand hits for the cap it would have used on the old one.

Nothing halts the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Woodlesford or out in Oulton.

How to tell the AdBlue filler from the diesel one

A couple of seconds is all the checks take — so run through them before you tip anything, on a drive in Churchfields or a forecourt in Woodlesford.

  • 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.
  • Many motors fit AdBlue the smaller neck of the two.
  • Lift the flap and look for a label — plenty of vehicles mark what belongs in which filler right there.
  • Cannot see it beside the diesel filler? In that case check below the bonnet or in your boot — the owner's manual says which.
  • Collecting a hire or company car, say at the car park at the nearest station? Check with whoever drove it last before you set off, rather than once the light goes on.

How to top up without AdBlue in the diesel tank

The day the light comes on, anywhere across West Yorkshire, use this routine.

  • Pull in somewhere level, motor off, with time to spare — not hurried on the side of Church Street.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
  • Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Only then, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened.

Spot at stage two or three that it's already gone into the diesel side? Then stop right there. Skip step five altogether.

Already put AdBlue in the diesel tank around Woodlesford?

Then the order of things is short. Do not start the motor. Keep your ignition off too, since on many diesels it alone runs your fuel pump. Thinning it with extra diesel fails, because AdBlue sinks to the base instead of mixing — and that's where the fuel is pulled from.

The staff at Shell, Esso or another forecourt will usually help pushing the car away if asked. At home in Woodlesford? So the car stays where it is.

When the motor has been run already, stop safely then turn it off. Leave the M1 — under 3 miles out of Woodlesford — at the next junction. Tell us roughly how far it went: a run towards Leeds, under 10 miles away, is a bigger job than a short hop across Woodlesford.

What happens when our engineers arrive around Woodlesford

Wherever the vehicle has stopped, be it outside Woodlesford Primary School, near Oulton Institute or on your own drive, the van comes to it. What fluid got in, the quantity, and whether it ran: our technicians ask since the replies set both work and quote. You hear that quote by phone, before anyone heads out.

Emptying your tank comes next, then a full flush of the fuel system. Much more than with petrol, it counts here: crystals form, certain metals corrode, and nothing clears out unaided, no matter how long it is left. Once your filter has been flushed — or renewed, where needed — clean diesel goes in, and finally the car gets tested. The engine is started next and checked to be sure it runs smoothly, all before our engineers leave.

Unstarted vehicles mostly mean a half-hour visit after the moment we arrive. The kit is fine on a busy forecourt, and hushed enough for a driveway after dark. No money 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 your insurer. Wrong-fuel cover is part of plenty of insurance policies — and so make use of the wait to check yours.
