AdBlue in a diesel motor: two tanks, two fillers

Diesel feeds your engine — yet plenty of current diesels seen around Horsley Woodhouse and Denby Village carry another liquid as well. Its own tank holds it, and from there it goes to the exhaust, and there spraying treats the gas.

Each tank comes with a filler of its own. Under one flap, next to each other: that's the layout on many vehicles. On others, AdBlue's filler is beneath the bonnet or in your boot instead. Diesel gets filled on each filling station call-out, again and again. A driver who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and much less regularly. The mistake grows in the gap between them.

Horsley Woodhouse: how AdBlue in the diesel tank occurs

Carelessness seldom causes it. Instead is three things lining up at once.

On a drive off Hollies Farm Drive before work, or in the car park at Old Oak Inn on the way home: that is where the rushed top-up happens. Why the rush? As AdBlue runs low the vehicle warns you, and if it is empty, limp mode follows.

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

Lastly, the bottle goes in: a diesel filler or AdBlue filler, it goes in as easily, and after the tip starts, no part halts it. The same few seconds settle it, in the middle of Horsley Woodhouse or out in Smalley.

Telling the AdBlue filler from the diesel filler

A few seconds is all the checks take — so check them before you pour anything, on a drive in Morley or a forecourt in Horsley Woodhouse.

  • Where it sits misleads; the cap doesn't. AdBlue ones are often blue or bear the name "AdBlue" — diesel caps normally do not.
  • Many cars give AdBlue the smaller neck of the two.
  • A label inside the fuel flap frequently shows which fuel goes where, on many vehicles. Check for it.
  • In the boot or under the bonnet: that is where your filler sits if it is not by your diesel cap, and the handbook tells you which.
  • Whoever had it before knows. Ask when you collect a rental or fleet car — at Duffield's car park, say — not when the light appears.

Topping up AdBlue without it reaching your diesel tank

Wherever across Derbyshire the light comes on, here is a routine for the day.

  • Switch off once parked — flat ground, engine off, and not in a rush beside The Mews at the roadside.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
  • The two behind one flap? So confirm the lid on your diesel filler is still closed ahead of lifting 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.

If at stage two or three you find you have already poured into your diesel side, stop there. Never go on to step five.

AdBlue in your diesel tank already, around Horsley Woodhouse?

Then the order of things is short. Do not start your motor. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with more diesel won't work, since AdBlue sinks to the base instead of mixing — and that is where the fuel is drawn from.

The attendants at JET, Texaco or any forecourt will normally lend a hand pushing the vehicle away when asked. Leave it where it is if you're on your own driveway in Horsley Woodhouse.

If the motor has already run, stop as soon as it is safe and switch off. The next exit is where to come off when you are on the M1, under 10 miles from Horsley Woodhouse. About how far did it go? Hopping across Horsley Woodhouse is smaller a job than a run of under 10 miles to Derby, so tell us.

When we get there in Horsley Woodhouse, what occurs?

By Horsley Woodhouse Primary School, near Horsley Woodhouse Central Methodist Church or on your own drive: wherever your car has stopped, our technicians come to it. We ask what was put in, roughly how much, and if it's run, since the answers determine this work and the price. During the call itself, you hear the price — ahead of dispatch.

After that: a drain, then a full flush of the entire 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. Filter cleaned or, where needed, swapped; fresh diesel in; and then a test of the vehicle. Next our engineers start the car and confirm it runs correctly before we leave.

Using pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs where the engine hasn't run need about half an hour after our engineers arrive. Your insurer will ask for the engineer's report and the VAT invoice, and you get both once the job is done. Payment is on the day, with no money upfront. While we travel, take a look at your insurance documents; plenty include cover for misfuelling.
