AdBlue in a diesel car: two tanks, two fillers

No single fluid but two: that is how plenty of newer diesels around Rosewell and Staiside Court carry, with diesel feeding the engine. Its own tank keeps it, and from there it goes to the exhaust, where a spray treats the fumes.

Each tank comes with one filler of its own. Other motors put the AdBlue filler in your boot or under the bonnet; plenty of others have the two together behind one flap. Diesel goes in at each filling station call-out, again and again. The AdBlue side is topped up far less regularly, normally from a bottle, and normally by somebody who has to stop and think where it goes. That gap is where the error lives.

AdBlue in the diesel tank around Rosewell: how it occurs

It's rarely carelessness. Three things tend to line up.

Haste follows from the warning. The car warns you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up happens in a rush, before work on a driveway off Louisa Square, or heading home in the car park at the pub in the village.

The old car's filler is where your hand goes — but a rental car, a new vehicle or a company car puts the fillers elsewhere. That's the second thing: an unfamiliar car.

A spout-topped bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, once begun, keeps on. Roslin or the heart of Rosewell: it takes the same few seconds in both.

How to tell the AdBlue filler from the diesel one

Look at these before pouring, at a forecourt around Rosewell or a drive out in Newbigging. Seconds, no more.

  • Check the cap rather than going by position: AdBlue ones are frequently blue or marked "AdBlue", and diesel ones usually are not.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • A label inside your fuel flap often shows which fuel goes where, on many vehicles. Check for it.
  • Can't see it beside your diesel inlet? In that case look below the bonnet or in your boot — the owner's manual will say which.
  • Collecting a hire or company car, perhaps at the car park at Newtongrange? Ask whoever drove the car last before you set off, rather than once the light comes on.

AdBlue top-ups that never reach the diesel tank

For the day the warning appears — wherever you are across Midlothian — a simple routine to use.

  • Not in a rush on the side of Greenside Place, not on a slope, not with the engine running: park and switch off properly.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Daft, yes, yet it does the trick.
  • Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Gently does it, through the bottle's own spout, till it's full or the bottle is empty.
  • Only then, start your car: close the cap, check once more, and make sure the diesel cap was never opened.

If at stage two or three you find you have already poured into the diesel side, stop there. Skip step five entirely.

Already put AdBlue in your diesel tank around Rosewell?

Short list, then. Top of that: your motor stays unstarted. Leave your ignition off too, since on plenty of diesels it by itself starts the pump. Topping up with diesel won't dilute it: rather than mixing, AdBlue sinks to the base of your tank, right where fuel is taken from.

The staff at Asda, Costco or another forecourt will normally lend a hand pushing your car clear when you ask. At home around Rosewell? So the vehicle stays put.

Already started? Stop when it is safe, then turn off. Rosewell sits under 10 miles from the M8; there, take the next junction. Mileage matters — a short hop across Rosewell is a smaller job than heading under 10 miles to Edinburgh — so tell us roughly how far it went.

Rosewell: what takes place when our engineers turn up

We come to the vehicle wherever it has stopped, whether that is outside the local primary school, close to Rosewell Mining and Associated Industries Memorial or on your own drive. Both the work and the price rest on three answers — which liquid, which amount, and whether it has run — so we ask. You get that quote on the phone, before anyone sets off.

Emptying your tank comes next, then a full flush of the system. More than with petrol, it matters with AdBlue: crystals build up, certain metals are attacked, and nothing clears out unaided, no matter how long it sits. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. We don't leave until it has been started and is running properly.

Unstarted cars usually need a half-hour visit from the moment we arrive. The kit is fine on a busy forecourt, and hushed enough for a residential street late at night. Payment is on the day, not upfront, and you receive the documents your insurer asks for: an engineer report and a VAT invoice. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.
