Why does AdBlue in a diesel vehicle need its own filler?

Plenty of newer diesels in Martlesham, as well as Maidensgrave, carry on two fluids; the engine gets only the diesel. AdBlue's own tank holds it, and from there it is sent to the exhaust, and there a spray treats the fumes.

Different tanks, separate fillers. Some cars put the AdBlue filler in your boot or under the bonnet; plenty of others place the two together behind one flap. Filling your diesel side at the pump goes on all the time. The AdBlue side is filled far less frequently, usually from a bottle, and normally by someone who has to stop and think where it goes. That gap is where the error lives.

How does AdBlue in your diesel tank take place around Maidensgrave?

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

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the car goes into limp mode. So the top-up is done in a hurry: on a driveway off California before work, or in the car park outside The Cherry Tree on the way home.

Then your car is unfamiliar. A hire car, a new motor or a company car puts the fillers where your last one didn't, and your hand gets to for the cap it would have used on the old one.

A spouted bottle meets no resistance at a diesel filler any more than at an AdBlue one. So the pour, once begun, carries on. Whether it happens in Drybridge Hill or the middle of Maidensgrave, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Maidensgrave

The AdBlue filler and your diesel filler: telling them apart

Whether a Maidensgrave forecourt or a drive out in Methersgate, take a couple of seconds on these before any is poured in.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually is not. Read it rather than going by position.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside your fuel flap for a label. Plenty of vehicles say there which fuel goes where.
  • The handbook says where it lives when your filler is not next to your diesel cap: your boot, or under the bonnet.
  • Picking up a hire or company car, perhaps at the car park at Woodbridge? Ask the person who drove the vehicle last before leaving, rather than when the light goes on.

AdBlue top-ups that never reach your diesel tank

For the day the warning comes on — wherever you are in Suffolk — a simple routine to follow.

  • Not in a rush on the side of Sandy Lane, not on a slope, not with your motor running: park and switch off properly.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave it on.
  • Using the bottle's own spout, pour slowly — and stop when it is full or 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 step two or three, that you've already poured into the diesel side. Don't carry on to step five.

Put AdBlue in the diesel tank around Maidensgrave already?

Brief list, then. First: your engine stays unstarted. Keep the ignition off as well, since on plenty of diesels switching it on by itself starts your fuel pump. Topping up with diesel will not dilute it: instead, AdBlue sinks to the bottom of the tank, right where fuel is drawn from.

Ask the staff to help roll the vehicle away from the pump if you're at a forecourt — the Shell, the Tesco or somewhere else. Leave it where it is if you're on your own drive around Maidensgrave.

Where the motor has been run already, stop somewhere safe and switch the vehicle off. Leave the M11 — under 50 miles out of Maidensgrave — at the first junction. A short hop across Maidensgrave is a smaller job than a run towards Colchester, under 25 miles away, so tell us roughly how far it went.

Our arrival around Maidensgrave, and what takes place next

By Kyson Primary School, close to Woodbridge Town Football Club or on your own driveway: wherever your car has stopped, our technicians come to it. Both the work and our price depend on three answers — which fluid, what amount, and if it has run — so our technicians ask. During the phone call itself, you are told our quote — before dispatch.

Emptying your tank comes next, then a thorough flush of the system. Unlike petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of it clears away by itself. That is why it counts more. Once your filter is cleaned — or replaced, if needed — fresh diesel is added, and then your car gets tested. Before leaving, our engineers start it and make sure that it's running correctly.

Using pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs in which your motor hasn't run need about half an hour once our technicians are there. Payment is on the day, not upfront, and you are given the paperwork your insurer asks for: an engineer report and a VAT invoice. Wrong-fuel cover is part of plenty of insurance policies — so use the wait to look at yours.
