AdBlue in a diesel car, and its separate tank

Diesel goes to your motor — yet plenty of newer diesels driven about Culfordheath and Little Livermere hold a second liquid as well. Stored in a tank of its own, AdBlue is fed into the exhaust stream to clean it.

Separate tanks, separate fillers. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Filling the diesel side at the pump goes on all the time. Seldom topped up, AdBlue usually goes in out of a bottle, poured by a driver who has to stop and think which cap to use. It is in that gap that the slip happens.

How AdBlue in the diesel tank occurs around Culfordheath

Carelessness seldom explains it. Instead is three things coming up together.

On a driveway off Seven Hills Lane before work, or in the car park outside the pub in the village heading home: that's where the rushed top-up happens. What is the reason for the rush? As AdBlue runs low the vehicle tells you, and once it is gone, limp mode kicks in.

Then, your hand goes for the cap it would have used on the old motor — since a hire car, a new motor or a company car puts the fillers somewhere your last one didn't.

A spout-topped bottle finds no obstacle at a diesel filler any more than at an AdBlue one. And so the tip, once started, carries on. It takes seconds, be it out in Ampton or right in the heart of Culfordheath.

How to tell the AdBlue filler from the diesel one

Check these first, on a forecourt in Culfordheath or a drive out in Brockley Corner. Seconds, no more.

  • Position misleads; the cap does not. AdBlue ones are often blue or carry the name "AdBlue" — diesel caps usually don't.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside the fuel flap for a label. Many vehicles say there which fuel goes where.
  • The handbook. If your filler is not by your diesel cap, it is in the boot or under the bonnet, and the handbook says which.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Thetford.

Topping up AdBlue without it reaching the diesel tank

The day the light goes on, anywhere around Suffolk, follow this routine.

  • Stop on level, engine off, with time to spare — never rushing on the side of Green Lane.
  • Silly as it sounds, saying "AdBlue" out loud as you unscrew the cap does the trick — once you've located your filler and read the cap.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave it on.
  • Gently does it, through the bottle's own spout, till it's full or the bottle is empty.
  • Before you start your car, shut the cap and check a second time that the diesel cap was never opened off.

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

Culfordheath: already put AdBlue in the diesel tank?

Do not start your engine: that is how the short order of things starts. Leave your ignition off as well, since on plenty of diesels switching it on by itself starts the pump. Filling up with diesel will not weaken it: rather than mixing, AdBlue sinks to the bottom of that tank, just where fuel is drawn from.

Ask the staff to help push your car away from the petrol pump if you're at a forecourt — the the nearest petrol station, the Sainsbury's or anywhere else. At home around Culfordheath? Then the vehicle remains where it is.

Already run? Stop once it is sensible, then turn off. Leave the M11 — under 50 miles out of Culfordheath — at the first exit. A short hop across Culfordheath is a smaller job than a run towards Ely, under 25 miles away, so tell us roughly how far it went.

What takes place when our engineers arrive around Culfordheath

Anywhere the vehicle has stopped, whether by Barnham Church of England Voluntary Controlled Primary School, near St Peter or at home, our van travels to it. Both the work and our price rest on three replies — which liquid, which amount, and if it has run — so our engineers ask. During the call itself, you hear our quote — ahead of anything else.

Then the tank is drained and the system cleaned thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more here than with petrol. A test comes last: before that, clean diesel goes in, and your filter is flushed or replaced as needed. Before we go, our engineers start the engine and make sure that it is running smoothly.

Using pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs where the motor has not run need roughly half an hour once our technicians are there. Your insurer will ask for the engineer's report and the VAT invoice, and both are yours once the job is done. Payment is on the day, with no deposit. It's worth looking at your insurance while we travel to you: misfuelling cover is included with many policies.
