AdBlue in a Diesel Tank in Ysgubor Newydd: Why It Occurs and How to Prevent It

Pause reading for a moment when the diesel tank already holds AdBlue in it: ignition off, engine off, and call 0333 366 0103. Caught before your motor runs, it's generally a drain and a thorough flush, done where the vehicle is in Ysgubor Newydd. If you're reading before it has happened, the rest of this page is about why it occurs and how to make sure it doesn't.

AdBlue in a diesel motor, and its separate tank

Plenty of newer diesels in Ffos-y-fran, as well as Ysgubor Newydd, carry on two liquids; the motor takes only your diesel. Kept in a tank of its own, AdBlue is sprayed into the exhaust stream and cleans it.

Different tanks, different fillers. Plenty of vehicles share a single flap for the two, whereas others move the AdBlue filler to your boot or under the bonnet. At the pump, your diesel side gets filled all the time. Much less regularly, the AdBlue side gets filled — normally from a bottle, by a person working out where it goes. It is in that gap that the error happens.

How does AdBlue in your diesel tank happen around Ysgubor Newydd?

It's seldom carelessness. Three things tend to line up.

The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Wallhead Road before work, or in the car park outside The Farmers Arms on the way home.

The old car's filler is where the hand goes — but a hire car, a new car or a company car puts the fillers somewhere else. That is the second thing: a new motor.

Third, the spout fits: a diesel filler or AdBlue filler, it goes in as readily, and once the tip starts, nothing stops it. It's seconds, whether out in Twynyrodyn or bang in the centre of Ysgubor Newydd.

The AdBlue filler and your diesel filler: telling them apart

Before you tip anything, whether on a drive in Cae-draw or a forecourt in Ysgubor Newydd, check these. They take a few seconds.

  • Where it sits misleads; the cap does not. AdBlue caps are often blue or bear the name "AdBlue" — diesel ones normally do not.
  • The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where.
  • Can't find it next to the diesel filler? In that case check below the bonnet or in your boot — the owner's manual will say which.
  • The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park outside Merthyr Tydfil, ask before you leave, not when the light comes on.

How to top up without AdBlue in the diesel tank

A routine for the day the light comes on, wherever in Merthyr Tydfil that is.

  • Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Glasier Road.
  • Daft as it sounds, speaking "AdBlue" out loud while you unscrew the cap does the trick — once you've found your filler and read the cap.
  • Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Close the cap and check again. Make sure your diesel cap was never opened. Only then start the vehicle.

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

Ysgubor Newydd: already put AdBlue in your diesel tank?

Then the order of things is short. Don't start the engine. Do not switch your ignition on; on many diesels that alone runs the fuel pump. Topping up with diesel won't dilute it: instead, AdBlue drops to the base of that tank, just where the fuel is drawn from.

The attendants at Applegreen, Esso or another forecourt will normally lend a hand to push your car away if you ask. Leave it where it is if you're on your own drive in Ysgubor Newydd.

Our arrival around Ysgubor Newydd, and what takes place next

Our engineers come to your car wherever it has stopped, whether that's outside the local primary school, close to Greenwood Close Community Building or on your own driveway. What fluid got in, the amount, and if it ran: our technicians ask since the replies decide both work and quote. You hear that quote by phone, before anybody sets off.

Emptying your tank comes next, followed by a thorough flush of the fuel system. Much more than with petrol, it counts with AdBlue: crystals build up, certain metals are attacked, and none of that clears away unaided, however long it is left. Once your filter is cleaned — or replaced, where required — fresh diesel goes in, and finally the vehicle gets tested. Before we go, our engineers start the car and check that it's running properly.

If the motor hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. No money in advance; you settle up on the day. At the end, the VAT invoice and the report from the engineer go to you for your insurer. It is worth looking at your policy while we travel to you: misfuelling cover comes with many policies.
