AdBlue in a diesel car: two tanks, two fillers

Plenty of newer diesels around New Parks, as well as Beaumont Leys, run on two liquids; your motor gets just your diesel. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has its own filler. Under one flap, side by side: that is the arrangement on many motors. On others, AdBlue's filler is under the bonnet or in your boot instead. Diesel goes in on every forecourt call-out, week in, week out. Seldom topped up, AdBlue normally goes in out of a bottle, poured by a driver who has to stop and think which filler it needs. The mistake lives in that gap.

How does AdBlue in the diesel tank occur in Beaumont Leys?

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

First, the warning. Low AdBlue triggers a warning from the vehicle, and letting it run dry leads to limp mode — so a rushed top-up, perhaps before work off Bennion Road, or at Keeper's Lodge on the way home that evening.

Then the car is unfamiliar. A hire car, a new motor 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.

A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the pour, after begun, carries on. It takes a few seconds, be it out in Anstey or right in the heart of Beaumont Leys.

Telling the AdBlue filler from your diesel filler

A few seconds is all the checks take — so check them before you tip anything, on a driveway in Thurcaston or a forecourt around Beaumont Leys.

  • Blue and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.
  • The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
  • Check inside the fuel flap: many vehicles have a label there saying which fuel goes where.
  • The handbook shows where it is when the filler is not next to your diesel cap: the boot, or under the bonnet.
  • The person who drove the car last. On a hire or company car collected from somewhere like the car park outside Leicester, ask before you leave, not when the light comes on.

How to top up without AdBlue in your diesel tank

On the day the light comes on — wherever you are across Leicestershire — a routine to use.

  • Switch off once parked — flat ground, motor off, and never in a rush by Beaumont Way at the roadside.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
  • The diesel cap stays on. Where the two sit under a flap, confirm it's shut before the bottle comes up.
  • Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
  • Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start the car.

Stop there if you find, at stage two or three, that you've already poured into your diesel side. Don't carry on to step five.

Beaumont Leys: already put AdBlue in your diesel tank?

Then the order of things is short. Do not start the engine. Leave your ignition off too, since on many diesels it alone starts your pump. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from.

The attendants at Tesco, BP or any forecourt will usually lend a hand to push the vehicle away if you ask. At home around Beaumont Leys? So your car remains put.

Where your motor has run by now, pull over somewhere safe and switch the vehicle off. On the M1, under 3 miles from Beaumont Leys, that means the next exit. A short hop across Beaumont Leys is a smaller job than a run towards Leicester, under 3 miles away, and so tell us roughly how far it went.

Our arrival around Beaumont Leys, and what occurs next

Wherever the vehicle has stopped, whether outside Heatherbrook Primary Academy, near Church of Christ the King or on your own drive, our van travels to it. The replies determine this work and our price, and so we ask what got in, roughly how much, and if it has run. During the call itself, you are told our price — ahead of dispatch.

Next: a drain, then a thorough flush of the whole system. Much more than with petrol, it matters with AdBlue: the crystals form, certain metals corrode, and nothing clears out unaided, no matter how long it sits. Testing is at the end: before that, fresh diesel goes in, and your filter is flushed or replaced if necessary. Next our technicians start the car and confirm it runs smoothly before leaving.

With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where the engine hasn't run need about half an hour once we arrive. The insurer will ask for the engineer's report and the VAT invoice, and both are yours once the job is done. Payment comes on the day, with no deposit. It is worth checking your insurance while we travel to you: misfuelling cover comes with plenty of policies.
