Avoiding AdBlue in a Diesel Tank in Malpas: Why It Occurs
Leave your engine and ignition off then call 0333 366 0103 now — the rest can wait if AdBlue is already in your diesel tank. Around Malpas, finding it before the motor runs usually leaves a drain and a thorough flush on the spot. Reading in advance? Then the rest covers how it happens and how to stop it ever happening.
Why does AdBlue in a diesel car need its own filler?
Plenty of modern diesels on the roads round Malpas and Crindau carry two liquids, not one. Diesel goes to your engine. Your exhaust, not the motor, is where AdBlue ends up: dosed into the gas to clean them, from its own tank.
There is a filler for each tank. Under one flap, next to each other: that is the layout on many motors. On others, AdBlue's filler is under the bonnet or in your boot instead. The diesel side is topped up at the petrol pump all the time. The AdBlue side is filled far less often, usually from a bottle, and normally by a person who has to stop and think where it goes. That gap is where the mistake lives.
How AdBlue in the diesel tank takes place around Malpas
Carelessness rarely explains it. Instead is three things lining up at once.
Haste follows from the warning. Your car tells you as AdBlue runs low, and an empty tank puts it into limp mode — so the top-up gets done in a rush, before work on a drive off Malpas Road, or heading home in the car park at Three Horseshoes.
Then your car is unfamiliar. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand gets to for the cap it would have used on the old one.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started. It's a few seconds, whether in Brynglas or right in the heart of Malpas.
How to tell the AdBlue filler from the diesel one
A couple of seconds is all the checks take — so run through them before you tip anything, on a driveway in Croes-y-mwyalch or a forecourt around Malpas.
- Read the cap rather than going by position: AdBlue caps are regularly blue or marked "AdBlue", and diesel ones usually aren't.
- Plenty of cars give AdBlue the smaller neck of the two.
- Open the filler flap and look for a label — plenty of vehicles show what belongs in each inlet just there.
- Can't see it beside the diesel filler? Then look beneath the bonnet or inside the boot — the owner's manual says where.
- The person who drove the car last. On a hire or company car picked up from somewhere like the car park outside Newport (South Wales), ask before you leave, not when the light comes on.
How to top up without AdBlue in the diesel tank
Anywhere in Newport the light comes on, this is a routine for the day.
- Stop on level, motor off, with time in hand — never hurried on the side of Graig Park Avenue.
- Locate the AdBlue filler, check the cap, and say the name "AdBlue" aloud while unscrewing it. It seems daft. It works.
- The two behind a single flap? Then confirm the lid on your diesel filler is still closed ahead of lifting the bottle.
- Slowly does it, through the bottle's own spout, until it is full or the bottle is empty.
- Before you start your car, close the cap and check a second time that the diesel cap was never came off.
If at step two or three you find you have already poured into your diesel side, stop there. Do not go on to stage five.
Already put AdBlue in the diesel tank around Malpas?
Then the order of things is short. Do not start your motor. Do not switch your ignition on; on many diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is drawn from — so don't top up with diesel to dilute it.
On a forecourt — BP, Texaco or another — the attendants will usually help push your car away, if you ask. Your own drive in Malpas is the place it stays.
Already run? Pull over when it is sensible, then turn off. On the M4, under a mile from Malpas, that means the next junction. Mileage counts — a quick hop across Malpas makes a smaller job than driving under 3 miles to Newport — so tell us roughly how far it went.
Malpas: what happens when our technicians arrive
Anywhere the vehicle has stopped, whether outside the local primary school, beside Malpas Community Centre or on your own drive, our van travels to it. What liquid went in, the quantity, and if it ran: our engineers ask because those answers set the work and quote. You get that quote on the phone, before anybody heads out.
Then your tank is cleared and the system rinsed thoroughly. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. We do not leave until it has been started and is running properly.
With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which your motor hasn't run need roughly half an hour once we are there. No money in advance; you settle up on the day. Afterwards, the VAT invoice and a report from the engineer are handed to you for your insurer. Many insurance policies include misfuelling cover, so it is worth checking yours whilst we're on the way.
