AdBlue in a diesel vehicle, and its separate tank

Many newer diesels on the roads around Maresfield and Ringles Cross carry two liquids, not one. Diesel goes to the engine. Stored in a tank of its own, AdBlue is sprayed into the exhaust gas to clean it.

Separate tanks, separate fillers. Under one flap, next to each other: that's the layout on many cars. Elsewhere, AdBlue's filler sits beneath the bonnet or in the boot instead. Diesel gets filled on each filling station visit, again and again. A driver who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and far less commonly. It's in the gap that the slip lives.

How does AdBlue in the diesel tank take place in Maresfield?

Three things tend to line up, and carelessness is rarely one of them.

Haste comes from the warning. The vehicle tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up gets done quickly, before work on a driveway off Straight Half Mile, or heading home in the car park at The Chequers Inn.

Unfamiliar cars are next, as well. Hire cars, new cars and company vehicles place their fillers differently, and the hand goes for the cap used on the old one.

A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, once begun, carries on. Maresfield Park or the heart of Maresfield: it takes the same few seconds either way.

Flushing a diesel fuel system after AdBlue, Maresfield

Which filler is for AdBlue, and which for diesel?

Look at these before pouring, on a forecourt in Maresfield or a driveway out in Down Street. Seconds, that's all.

  • Blue and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits.
  • The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside the fuel flap for a label. Plenty of motors say there which fuel goes where.
  • The handbook. If the filler isn't by your diesel cap, it's in your boot or under the bonnet, and the handbook says which.
  • The person who drove the car last. On a hire or company car collected from somewhere like the car park outside Buxted, ask before you leave, not when the light comes on.

Topping up AdBlue without it reaching the diesel tank

The day the light comes on, wherever around East Sussex, use this routine.

  • Pull in somewhere level, motor off, with time in hand — never rushing on the side of Batts Bridge Road.
  • Find the AdBlue filler, check the cap, and say the word "AdBlue" aloud as unscrewing it. It seems daft. It does the trick.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave it on.
  • Finish once your tank is topped up or the bottle is empty; before that, pour slowly using the built-in spout.
  • Close the cap, and look again — confirm your diesel cap stayed shut throughout. Only then, start the car.

Spot at stage two or three that it has already gone into your diesel side? So stop right there. Do not go on to step five.

Put AdBlue in the diesel tank around Maresfield already?

Then the order of things is short. Do not start the motor. Keep your ignition off too, since on plenty of diesels switching it on alone starts your pump. Diluting it with more diesel fails, since AdBlue settles to the bottom instead of mixing — and that is where your fuel is pulled from.

On a forecourt — Shell, JET or any other — the staff will normally help roll the vehicle clear, if you ask. At home around Maresfield? Then the car stays where it is.

Already run? Stop once it's sensible, then turn off. Maresfield sits under 15 miles from the M23; on it, use the first exit. Tell us about how far it went: a run towards Brighton and Hove, under 25 miles away, is a bigger job than a short hop across Maresfield.

When our engineers get there in Maresfield, what occurs?

Our engineers come to the car wherever it has stopped, whether that's outside Bonners CofE School, near St Bartholomew’s Church or on your own driveway. What liquid went in, the quantity, and if it ran: our technicians ask since those replies set the work and price. That price is given on the call, ahead of any van leaving.

Then your tank is cleared and your system flushed thoroughly. Much more than with petrol, it matters here: crystals build up, certain metals are attacked, and nothing washes away unaided, no matter how long it is left. Once the fuel filter has been cleaned — or replaced, if required — clean diesel goes in, and finally your car is tested. Then our technicians start the car and check it runs properly before we leave.

With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which the motor has not run need about half an hour once our technicians are there. Your insurer usually wants the engineer's report and your VAT invoice, and you get both at the end. Payment is on the day, with no deposit. Many insurance policies include misfuelling cover, and so it is worth checking yours while we are on the way.
