AdBlue in a Diesel Tank in Noss Mayo: Why It Occurs and How to Avoid It
AdBlue already in the diesel tank? Then put this page down a moment, keep the ignition and engine off, then phone 0333 366 0103. Normally, if the motor hasn't run, it's emptied and thoroughly cleaned where your vehicle is around Noss Mayo. Nothing happened yet? Below, the rest of the page covers the why it occurs and the ways to prevent it altogether.
Why does AdBlue in a diesel vehicle need its own filler?
Many modern diesels on the roads about Noss Mayo and Membland carry two liquids, not one. Diesel goes to your motor. The exhaust, not your motor, is where AdBlue goes: sprayed into the fumes to fresh them, from a separate tank.
Every tank comes with one filler of its own. Many of vehicles share a single flap for both, whereas some move the AdBlue filler to your boot or under the bonnet. Filling your diesel side at the pump goes on constantly. Far less frequently, the AdBlue side is filled — mostly from a bottle, by a person working out where it goes. It is in that gap that the slip lives.
Noss Mayo: how AdBlue in the diesel tank takes place
Rarely is it carelessness: normally three things line up.
The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Revelstoke Road before work, or in the car park outside The Swan Inn on the way home.
Then your car is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and your hand reaches 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, and so nothing stops the tip once it has started. The same few seconds settle it, in the middle of Noss Mayo or out in Newton Ferrers.
How to tell the AdBlue filler from the diesel one
A couple of seconds is all these take — so check them before you tip anything, on a drive in Knighton or a forecourt around Noss Mayo.
- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap normally isn't. Read it instead of going by where it sits.
- Check the size: the smaller neck is, on plenty of cars, the AdBlue one.
- Look inside your fuel flap: many vehicles have a label there showing which fuel goes where.
- The handbook shows where it lives when the filler is not next to your diesel cap: your boot, or under the bonnet.
- The previous driver knows. Check when you collect a rental or company car — at Plymouth's car park, perhaps — rather than once the light appears.
Topping up AdBlue without it reaching the diesel tank
When the light comes on, wherever around Devon, use this routine.
- Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Pillory Hill.
- Find the AdBlue filler, check the cap, and speak the name "AdBlue" aloud while you unscrew it. It sounds daft. It does the trick.
- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the car on.
- Slowly is best, through the bottle's own spout, until it's full or the bottle runs out.
- Only then, start the car: close the cap, check a second time, and make sure your diesel cap was never opened.
Find during the second or third stage that AdBlue went in the diesel filler? That is where you stop. Never carry on to step five.
Already put AdBlue in your diesel tank in Noss Mayo?
Then the order of things is short. Don't start the engine. Leave your ignition off as well, because on many diesels switching it on by itself runs the pump. Thinning it with extra diesel fails, since AdBlue sinks to the base rather than mixing — and that's where the fuel is sucked from.
Ask the attendants to help push your car clear of the petrol pump if you're at a forecourt — the Valero, the Texaco or somewhere else. At home in Noss Mayo? So your car stays put.
Already run? Pull over when it is sensible, then switch off. On the M5, under 50 miles from Noss Mayo, that means the next junction. Mileage counts — a quick hop across Noss Mayo makes a smaller job than driving under 10 miles towards Plymouth — so say about how far it went.
Our arrival around Noss Mayo, and what happens next
Wherever the vehicle came to rest, be it by Newton Ferrers Church of England Primary School, near St Peter's Church or at home, our van travels to it. The replies determine the work and the quote, and so our engineers ask what went in, roughly how much, and whether it's run. You get that price on the phone, before anybody sets off.
Your system is then purged thoroughly, once the tank is drained. Much more than with petrol, it counts with AdBlue: crystals form, certain metals are attacked, and nothing washes out unaided, however long it is left. Once your filter has been flushed — or replaced, where required — clean diesel goes in, and then your car is tested. Then our technicians start the engine and confirm it runs smoothly before leaving.
If your motor has not run, most jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is included in many insurance policies — and so make use of the wait to look at yours.
