New filler-cap design will stop drivers putting petrol in diesel models

Audi has developed a new fuel filler cap to stop owners accidently filling their diesel models with petrol.

Audi A4, A5 and Q5 TDI models for the 2011 model year will be the first to benefit from the new system.

The fuel filler neck has been redesigned to incorporate contact points that open an internal fuel flap only when the larger diesel pump nozzle applies pressure on them.

The smaller diameter petrol nozzles do not make contact, ensuring that the filler flap remains closed to prevent access to the reservoir.

Instances of misfuelling have risen significantly in recent years creating inconvenient and potentially expensive consequences.

Audi believes this is due to the increased refinement of diesel models which has seen them run nearly as smoothly and quietly as their petrol counterparts.

Our Verdict

Audi A4
The Audi A4 saloon is bigger, roomier and more aerodynamic than its predecessor

The Audi A4 is an improvement over the previous version, but isn't good enough to topple the BMW 3-series

Isnt this a rather embarassing 'news' story? Ford has been fitting its cars with this sort of device for ages now.

Next thing you know BMW will be making news for coming up with a twin opening tailgate.....

Interesting that Audi consider their customers likely to fill their diesel tanks with petrol in the first place. I thought everyone who bought an Audi would know the difference between the two fuels. Then again...

Indeed,

but given that so many audis are company/renta-cars, i guess these things happen. Still, at least they are refined

Competance executes, character inspires

There is already a pefectly good free system around to do this. It has been evolving and refining for millions of years and is called a brain.

FORD got there first, introduced 2 years ago!!

Vorsprung Durch Copying Ford!

How on earth can anyone make this mistake with an Audi anyway? VAG four-cylinder diesels sound like tractor engines...

Don't you just love marketing? Especially when the magazines churn it out for you...

Yep they certainly did. I've got it on my 2008 Focus and it works. I know this because after a very slight fuel leak problem around the filler neck, Ford replaced the fuel filler neck, except they put a petrol one on my diesel as I found out when I tried to fill it up.

After Ford resolved that issue (and it has been fine ever since), I had a chat with one of their service guys who said the system works very well, and at the time (about 18 months ago) they had only had one misfuel on a car fitted with it; turns out an AA recovery chap was having difficulty putting petrol into another Focus (as it was a diesel), so took a screwdriver to the flap and smashed it open.
