AdBlue in a diesel car: two tanks, two fillers

No single fluid but two: that's what plenty of newer diesels around Tividale Hall and Grace Mary Estate carry, with diesel for the motor. Kept in a tank of its own, AdBlue is fed into your exhaust stream to clean it.

Different tanks, separate fillers. Other vehicles put the AdBlue filler in your boot or under the bonnet; plenty of others have both together under one flap. Diesel goes in at every filling station visit, week in, week out. The AdBlue side is filled far less often, normally from a bottle, and normally by somebody who has to stop and think where it goes. It is in that gap that the error happens.

AdBlue in the diesel tank in Tividale Hall: how it takes place

Carelessness rarely explains it. Instead is three things coming up at once.

The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a drive off Regent Road before work, or in the car park outside Albion Inn on the way home.

Next, your hand goes for the cap it would have used on the old car — since a hire car, a new vehicle or a company car places the fillers somewhere your last one didn't.

Third, the spout goes in: diesel filler or AdBlue filler, it slides in just as readily, and once the tip begins, nothing stops it. Oakham or the middle of Tividale Hall: it takes the same few seconds either way.

Telling the AdBlue filler from the diesel filler

Before you tip anything, whether on a drive in Tansley Hill or a forecourt around Tividale Hall, check these. They take a couple of seconds.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap usually is not. Read it rather than going by where it sits.
  • Plenty of cars fit AdBlue the smaller filler of the two.
  • A label inside the fuel flap often shows which fuel goes where, on plenty of motors. Check for it.
  • The handbook. If your filler isn't by the diesel cap, it is in your boot or under the bonnet, and the handbook says which.
  • Picking up a hire or company car, perhaps at the car park outside Dudley Port? Ask the person who drove the vehicle last before leaving, not once the light comes on.

Topping up AdBlue without it reaching the diesel tank

Wherever in West Midlands the light comes on, here is a routine for the day.

  • Park then switch off. Not on a slope, not with your motor running, and not in a rush on the side of Barncroft Road.
  • Daft as it sounds, speaking "AdBlue" out loud as you unscrew the cap works — after you have found the filler and read it.
  • The diesel cap stays on. Where the two sit under a flap, make sure it is shut before lifting the bottle.
  • Stop once that tank is topped up or the bottle runs dry; until then, pour gently through the built-in spout.
  • Close the cap, then look again — confirm your diesel cap remained closed the whole time. Only then, start the car.

Stop there if you find, at step two or three, that you've already poured into the diesel side. Do not go on to stage five.

Already put AdBlue in your diesel tank around Tividale Hall?

Brief order, then. Top of it: your motor stays unstarted. The fuel pump starts on many diesels as soon as the ignition goes on — and so keep it off. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is sucked from.

If you're on a forecourt, whether it's the Tesco or the another forecourt nearby, ask the staff to help push the car away from the petrol pump. Your own drive in Tividale Hall is where it stays.

Already started? Stop when it is sensible, then turn off. Tividale Hall lies under 3 miles from the M5; on it, use the next junction. Tell us about how far it went: a run towards Wolverhampton, under 10 miles away, is a bigger job than a short hop across Tividale Hall.

Our arrival around Tividale Hall, and what takes place next

By Tividale Hall Primary School, close to Darby's Hill Viewpoint or on your own driveway: wherever your car has stopped, our technicians come to it. What liquid got in, the quantity, and whether it ran: our engineers ask since the replies decide the work and quote. Nobody heads out until you have heard our price by phone.

After that: a drain, then a full flush of the whole system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Testing is at the end: before that, clean diesel goes in, and your filter is cleaned or replaced if necessary. The motor is started next and tested to confirm it runs smoothly, all before our engineers leave.

If the motor hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. No money upfront; you settle up that day. At the end, the VAT invoice and a report from the engineer go to you for your insurer. It is worth looking at your policy as the van travels to you: misfuelling cover comes with plenty of policies.
