Preventing AdBlue in a Diesel Tank in Emersons Green: Why It Occurs
AdBlue already in your diesel tank? In that case put this page down a moment, keep your ignition and engine off, and call 0333 366 0103. In Emersons Green, catching it before the motor runs usually means draining and a thorough flush where it stands. Not happened yet? Below, the rest of the page covers the why it occurs and the ways to avoid it for good.
Why does AdBlue in a diesel vehicle need its own filler?
No single fluid but two: that's how many modern diesels near Emersons Green and Vinney Green run, with diesel for your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
There is a filler on every tank. Under one flap, side by side: that is the arrangement on many cars. On others, AdBlue's filler is under the bonnet or in your boot instead. The diesel side is filled at the pump all the time. A driver who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and much less commonly. It is in the gap that the slip lives.
How AdBlue in your diesel tank occurs in Emersons Green
Rarely is it carelessness: usually three things line up.
The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, your vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Richmond Road before work, or in the car park outside The Lamb Inn on the way home.
Unfamiliar cars are next, too. Rentals, new vehicles and company vehicles place their fillers in new places, and the hand goes for the cap it used on the old one.
Lastly, the spout goes in: diesel filler or AdBlue one, it slides in just as easily, and after the tip starts, no part halts it. The same few seconds decide it, in the middle of Emersons Green or out in Blackhorse.
The AdBlue filler and the diesel filler: telling them apart
Before you pour anything, whether on a driveway in Mangotsfield or a forecourt in Emersons Green, check these. They take a few seconds.
- Check the cap rather than going by where it sits: AdBlue ones are often blue or marked "AdBlue", and diesel caps normally aren't.
- The size. On many cars the AdBlue filler neck is the smaller of the two.
- Lift the filler flap and look for a label — plenty of motors show what goes in each inlet just there.
- The handbook. If your 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 Bristol Parkway? Ask whoever drove the car last before leaving, rather than when the light goes on.
AdBlue top-ups that never reach your diesel tank
On the day the light comes on — wherever you are around Gloucestershire — a routine to follow.
- Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Blackhorse Road.
- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, perhaps, yet it does the trick.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on.
- Finish when the tank is topped up or the bottle is empty; before that, pour slowly using the own spout.
- Close the cap and check once more. Make sure the diesel cap was never opened. Only then start your car.
Discover during the second or third stage that the bottle went into the wrong filler? That is where you stop. Don't go on to step five.
Put AdBlue in the diesel tank in Emersons Green already?
The short order of things, beginning with no starting the engine. Keep the ignition off as well, because on plenty of diesels switching it on alone starts the fuel pump. Thinning it with more diesel fails, because AdBlue sinks to the bottom instead of mixing — and that is where the fuel is sucked from.
The attendants at Sainsbury's, Shell or another forecourt will normally help to push the vehicle away if you ask. If you're on your own drive in Emersons Green, leave it where it stands.
If your engine has already run, stop as soon as it is safe then switch off. On the M4, under 3 miles from Emersons Green, that means the next junction. Tell us about how far it went: a run towards Bristol, under 10 miles away, is a bigger job than a short hop across Emersons Green.
What happens when we arrive in Emersons Green
Wherever the car has stopped, whether outside Mangotsfield Church of England Primary School, beside 2152 (Downend) DF Air Training Corps or on your own drive, the van comes to it. Both the work and the quote depend on three replies — what liquid, what quantity, and whether it has run — so our technicians ask. You get that quote by phone, before anyone heads out.
After that: draining, then a thorough flush of the entire system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. The filter cleaned or, if it must be, replaced; fresh diesel in; then a check of your vehicle. The engine is fired up next and tested to confirm it runs correctly, all before our engineers leave.
Using pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs where the engine has not run need roughly half an hour once our technicians are there. No money in advance; you settle up that day. Afterwards, a VAT invoice and the report from the engineer go to you for the insurer. Many insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.
