Two fillers, two tanks: AdBlue in a diesel motor

Plenty of newer diesels in Broomhill, like those in Eastside, carry on two fluids; the engine gets just the diesel. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Separate tanks, different fillers. Plenty of vehicles share a single flap for the two, while others move the AdBlue filler to your boot or under the bonnet. Diesel goes in at every forecourt visit, week in, week out. Far less regularly, the AdBlue side gets topped up — mostly from a bottle, by a person working out where it goes. That gap is where the slip lives.

How AdBlue in your diesel tank takes place around Eastside

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

First, the warning. Low AdBlue triggers a message from your car, and letting it run out leads to limp mode — so a hurried top-up, perhaps before work off Hillhead Roundabout, or outside Kirky Puffer on the way home that evening.

The old car's cap is where the hand goes — yet a rental car, a new car or a company car keeps the fillers somewhere else. That's a second thing: a strange car.

Nothing stops the pour after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it takes place in Kirkintilloch or the middle of Eastside, it's the same few seconds.

Flushing a diesel fuel system after AdBlue, Eastside

Which filler is for AdBlue, and which for diesel?

A couple of seconds is all the checks take — so check them before you pour anything, on a driveway in Hillhead or a forecourt in Eastside.

  • Read the cap instead of going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps normally aren't.
  • On many motors, size tells: AdBlue has the smaller filler neck.
  • 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 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 company car — at Lenzie's car park, say — not once the light appears.

AdBlue top-ups that never reach your diesel tank

The day the light goes on, wherever across East Dunbartonshire, use this routine.

  • Pull in on level, motor off, with time to spare — not hurried on the side of Peter D Stirling Road.
  • 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 both share a flap, make sure it is shut before lifting the bottle.
  • Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
  • Close the cap, and look once more — confirm your diesel filler stayed closed the whole time. After that, start the vehicle.

Stop there if you find, at step two or three, that you've already poured into your diesel side. Stage five stays out.

Already put AdBlue in the diesel tank around Eastside?

Then the order of things is short. Don't start the engine. Leave the ignition off too, because on plenty of diesels it by itself runs the pump. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where the fuel is pulled from — so don't top up with diesel to dilute it.

On a forecourt — Shell, Gulf or any other — the staff will normally help push the vehicle away, if you ask. At home in Eastside? So your car stays put.

When your engine has been run already, pull over somewhere safe and turn the vehicle off. Eastside lies under 3 miles from the M80; there, take the next exit. A short hop across Eastside is a smaller job than a run towards Glasgow, under 10 miles away, so tell us about how far it went.

Our arrival around Eastside, and what takes place next

We come to the car wherever it has stopped, whether that's outside the local primary school, near The Turret Theatre or on your own drive. The replies determine this work and the price, so our technicians ask what was put in, about how much, and whether it's run. No one sets off until you've had our price by phone.

Then your tank is emptied and the fuel system purged thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why that matters more with AdBlue than with petrol. The filter cleaned or, where it must be, swapped; fresh diesel in; and then a test of the car. After that our technicians fire it up and confirm it runs properly before we leave.

If your engine hasn't run, the majority of 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. Nothing upfront; you settle up that day. Afterwards, the VAT invoice and a report from the engineer are handed to you for the insurer. While we travel, take a look at your insurance documents; many include cover for misfuelling.
