AdBlue in a Diesel Tank in Toftwood: Why It Happens and How to Stop It

Leave the motor and ignition off then call 0333 366 0103 first — reading can wait if AdBlue is already in the diesel tank. Caught before your motor runs, it's usually a drain and a thorough flush, done where your car is around Toftwood. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it does not.

Why does AdBlue in a diesel motor need its own filler?

Plenty of newer diesels on the roads around Toftwood and Westfield carry two liquids, not one. Diesel goes to your engine. 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 is a filler on every tank. Plenty of cars share a single flap for both, while others move the AdBlue filler to your boot or under the bonnet. At the petrol pump, your diesel side gets filled constantly. Seldom topped up, AdBlue usually comes out of a bottle, poured by a driver who has to stop and think which filler it needs. That gap is where the mistake lives.

AdBlue in the diesel tank around Toftwood: how it happens

It's hardly ever carelessness. Three things tend to line up.

Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Margaret Close, or on the way home in the car park at The Millwright Arms.

The old car's cap is where the hand goes — but a hire car, a new vehicle or a company car keeps the fillers elsewhere. That's the second thing: a strange vehicle.

Nothing halts the tip once it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it occurs in South Green or the middle of Toftwood, it's the same few seconds.

How to tell the AdBlue filler from the diesel one

Before you tip anything, whether on a driveway in Yaxham or a forecourt around Toftwood, check these. They take a few seconds.

  • The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap normally is not. Read it instead of going by where it sits.
  • Look at the size: the smaller neck is, on many vehicles, the AdBlue one.
  • The flap. Look inside the fuel flap for a label. Many cars say there which fuel goes where.
  • In the boot or under the bonnet: that's where the filler sits if it's not by the diesel cap, and the handbook tells you which.
  • Collecting a hire or company car, say at the car park outside Wymondham? Ask whoever drove the car last before you set off, not once the light comes on.

How to top up without AdBlue in the diesel tank

A routine for the day the light comes on, wherever across Norfolk that is.

  • Turn off once parked — level ground, engine stopped, and not in a rush beside Shipdham Road on the verge.
  • Silly as it sounds, saying "AdBlue" out loud while you unscrew the cap works — after you have found the filler and read the cap.
  • 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.
  • Close the cap and check once more. Make sure your diesel cap was never opened. Only then start the vehicle.

Stop there if you find, at stage two or three, that you have already poured into your diesel side. Step five stays off limits.

Toftwood: already put AdBlue in your diesel tank?

Brief list, then. Top of that: your engine stays off. The fuel pump runs on plenty of diesels as soon as your ignition goes on — and so leave it off. Filling up with diesel won't dilute it: rather than mixing, AdBlue sinks to the base of that tank, just where the fuel is taken from.

The attendants at Tesco, BP or any forecourt will normally help to push the vehicle clear when asked. At home around Toftwood? So the car remains where it is.

Stop as soon as it is safe and switch off, if the engine has already run. Toftwood lies under 50 miles from the M11; there, use the first exit. About how far did it go? Crossing Toftwood is less work than a run of under 25 miles towards Norwich, and so say.

When our engineers turn up in Toftwood, what occurs?

By Toftwood Infant School, near Toftwood Social Club or on your own driveway: wherever the vehicle has stopped, our technicians come to it. Both the work and the quote rest on three answers — which liquid, what quantity, and if it's run — so we ask. During the call itself, you hear our quote — ahead of anything else.

Next: a drain, then a thorough flush of the whole system. Unlike petrol, AdBlue forms crystals and attacks some fuel-system metals, and none of it clears out unaided. That is why it counts more. Testing is at the end: before that, fresh diesel goes in, and the fuel filter is cleaned or replaced as needed. Before we go, we fire it up and confirm that it is running smoothly.

Most jobs are finished in about half an hour after our engineers get there, as long as the engine hasn't run — and the pumps our engineers use are safe on a busy forecourt yet quiet after dark beside a house. Your insurer usually wants the engineer's report and the VAT invoice, and you get both once this job is done. Payment is on the day, with no money upfront. Wrong-fuel cover is part of many insurance policies — so use the wait to look at yours.
