Bear Cross: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

Stop reading a minute if your diesel tank already has AdBlue in it: ignition off, engine off, and ring 0333 366 0103. Caught before the engine runs, it's generally a drain and a thorough flush, done where the car is in Bear Cross. Reading before the event? In that case what follows explains why it happens and what to stop it happening at all.

AdBlue in a diesel motor, and its separate tank

Not one fluid but two: that's how many newer diesels near Bear Cross and Kinson run, with diesel for the engine. AdBlue's own tank holds it, and from there it is sent to the exhaust, where a spray treats the fumes.

There's a filler on every tank. Under one flap, side by side: that's the arrangement on many cars. On others, AdBlue's filler is under the bonnet or in the boot instead. The diesel side is fuelled at the pump all the time. Far less often, the AdBlue side gets filled — normally from a bottle, by a person working out where it goes. The slip lives in that gap.

How AdBlue in the diesel tank happens around Bear Cross

Three things tend to come together, and carelessness is rarely one of them.

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 gets done quickly, before work on a drive off Fulwood Avenue, or heading home in the car park at The Bear Cross.

The old car's filler is where the hand reaches — yet a hire car, a new car or a company car keeps the fillers somewhere else. That is a second factor: an unfamiliar vehicle.

Nothing halts the tip once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It takes seconds, whether out in Bearwood or bang in the heart of Bear Cross.

Telling the AdBlue filler from the diesel filler

Before you tip anything, whether on a drive in Turbary Common or a forecourt in Bear Cross, check these. They take a few seconds.

  • The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap normally is not. Read it instead of going by position.
  • On plenty of cars, size tells: AdBlue has the smaller filler neck.
  • A label inside your fuel flap often shows which fuel goes where, on many cars. Check for it.
  • Cannot see it next to the diesel inlet? Then look below the bonnet or inside your boot — the owner's manual says where.
  • Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park at Branksome.

Topping up AdBlue without it reaching the diesel tank

For the day the warning comes on — wherever you are around Dorset — a simple routine to use.

  • Pull in somewhere level, motor off, with time to spare — never hurried on the side of Lydwell Close.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • The diesel cap remains on. Where both share a flap, make sure it's closed before the bottle comes up.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Shut the cap, then check once more — confirm the diesel cap stayed shut throughout. After that, start the vehicle.

Find at stage two or three that it's already gone into your diesel side? So stop right there. Step five stays out.

Bear Cross: already put AdBlue in your diesel tank?

Do not start the engine: that is how the short order of things begins. On many diesels the ignition alone runs the fuel pump, so don't switch it on. Diluting it with more diesel fails, because AdBlue settles to the bottom instead of blending — and that is where the fuel is drawn from.

Ask the attendants to help push your car away from the petrol pump if you're on a forecourt — the Texaco, the BP or anywhere else. Your own driveway in Bear Cross is the place it stays.

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 M27, under 25 miles from Bear Cross. Mileage counts — a quick hop across Bear Cross makes a smaller job than driving under 25 miles to Salisbury — so say about how far it went.

When we arrive in Bear Cross, what occurs?

Anywhere the vehicle has stopped, be it outside Christ The King Catholic Primary School, beside Chapel or at home, the van travels to it. Our engineers ask what was put in, roughly how much, and whether it's run, since those answers determine this work and the price. On the phone call itself, you are told the quote — before dispatch.

Emptying the tank comes next, followed by a full flush of the fuel system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. A test comes at the end: before that, clean diesel is added, and the filter is flushed or changed if necessary. Next our technicians start the engine and confirm it runs smoothly before we leave.

With pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs where the engine hasn't run take roughly half an hour once our engineers arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Before we get there, have a look at your policy; many include cover for misfuelling.
