AdBlue in a diesel motor: two tanks, two fillers

Many modern diesels around Deptford, as well as New Cross Gate, carry on two fluids; the motor takes just the diesel. Stored in a tank of its own, AdBlue is fed into your exhaust stream to clean it.

Separate tanks, different fillers. Other motors put the AdBlue filler in your boot or under the bonnet; plenty of others place the two side by side behind one flap. Filling the diesel side at the petrol pump goes on constantly. Rarely filled, AdBlue usually comes out of a bottle, tipped by someone who has to stop and think which cap it needs. That gap is where the error lives.

How does AdBlue in the diesel tank occur in New Cross Gate?

Seldom is it carelessness: usually three things coincide.

First, the warning. Low AdBlue brings a message from the vehicle, and running dry means limp mode — hence a hurried top-up, maybe before work off Dennett's Road, or outside The Telegraph at The Earl of Derby on the way home that evening.

Next, the hand reaches for the cap it would have used on the old motor — because a rental car, a new motor or a company car puts the fillers somewhere your last one did not.

Third, the bottle fits: a diesel filler or AdBlue filler, it slides in just as readily, and after the pour starts, nothing halts it. New Cross or the middle of New Cross Gate: it takes the same few seconds either way.

Flushing a diesel fuel system after AdBlue, New Cross Gate

Which filler is for AdBlue, and which for diesel?

A couple of seconds is all the checks take — so run through them before you pour anything, on a driveway in St Johns or a forecourt around New Cross Gate.

  • Where it sits misleads; the cap does not. AdBlue caps are often blue or carry the name "AdBlue" — diesel ones usually don't.
  • The size. On many vehicles the AdBlue filler neck is the smaller of the two.
  • Check inside the fuel flap: plenty of cars have a label there showing which fuel goes where.
  • The handbook. If the filler isn't by the diesel cap, it is in your boot or under the bonnet, and the handbook says which.
  • Picking up a hire or company car, say at the car park at Nunhead? Check with the person who drove the car last before leaving, rather than when the light goes on.

How to top up without AdBlue in your diesel tank

Wherever in Greater London the light comes on, here is a routine for that day.

  • Pull in somewhere level, motor off, with time in hand — never rushing on the side of Rutt's Terrace.
  • Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap does the trick — once you have found the filler and read the cap.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave the car on.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Only after that, start the vehicle: close the cap, check once more, and make sure your diesel cap was never opened.

Stop there if you find, at stage two or three, that you have already poured into your diesel side. Skip stage five entirely.

Already put AdBlue in your diesel tank in New Cross Gate?

Don't start your engine: that's how the short order of things begins. On plenty of diesels the ignition alone runs the fuel pump, so don't switch it on. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where the fuel is sucked from — so don't top up with diesel to thin it.

On a forecourt — Sainsbury's, Shell or any other — the attendants will usually help push your car away, when you ask. Your own driveway around New Cross Gate is where it stays.

Already started? Stop once it's sensible, then turn off. New Cross Gate lies under 10 miles from the M11; on it, take the first junction. About how far did it go? Crossing New Cross Gate is less a job than a run of under 5 miles to London, and so tell us.

When our engineers arrive in New Cross Gate, what takes place?

We come to the vehicle wherever it has stopped, whether that's outside Edmund Waller Primary School, close to The Somerville Centre or on your own drive. The answers decide this work and our price, so we ask what went in, about how much, and if it has run. You get that quote by phone, before anybody sets off.

The fuel system is then cleaned thoroughly, after your tank is cleared. Much more than with petrol, it matters with AdBlue: the crystals build up, certain metals corrode, and nothing clears away on its own, no matter how long it is left. Testing is at the end: before that, clean diesel goes in, and the fuel filter is cleaned or replaced if necessary. After that we start the car and make sure it runs smoothly before leaving.

Most jobs are done in about half an hour once we arrive, provided your engine hasn't run — and the pumps our engineers use are safe on a live forecourt and quiet at night beside a house. Nothing in advance; you settle up on the day. Afterwards, a VAT invoice and a report from the engineer are handed to you for your insurer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we are on the way.
