I just noticed the sticker on the inside of the filler flap, whilst refueling. It warned "not suitable for bio diesel". The pump sticker stated 7% bio diesel. By this time, I had filled up and was hoping for the best.

On returning home, I checked with the service department of Audi Aberdeen and they advised that it was OK at 7%. Apparently, this has been the case, i.e. 7% content, for approximately a year. There have been no problems.

I thought I would share this with you all and wonder whether anybody else has picked up on this issue?

Yes, I noticed the same last week when I filled up my brand new car at a BP garage. Did some 'googling' to find much of the diesel sold now has 5% bio diesel in it (some EU green policy!), but it has put me off using BP in future. I checked at the Shell garage a few days ago, and no mention of bio diesel.

What is wrong with biodiesel - its manufactured to equivalent standards as mineral diesel and has no downside or side effects. In reality you'd not be able to tell the difference!

I think that is exactly what the problem is and why Audi say NO!

A little reading matter..... Here!

Interesting article but it does have some big errors in it and im no expert but i would suggest that there could be more!

Biodiesel has regulations the same as mineral diesel, if its made to these standards and sold as such its just as safe as mineral diesel. The article says there arent engines that can run on all blends, until a few months back i owned a vehicle with an engine you could run on anything, it was a diesel engine that ran on mineral diesel, straight veg oil, petrol, meths, white spirit and all sorts of blends of the above!

I don't think it's a question of whether or not it will run on Bio but a question of engine longevity. I'm pretty sure the Q5 would run on Kero or even butter for that matter but for how long?

As for the credibility of the article, you'd need to temper the information with the date it was produced (2008 if I remember correctly) but Ricardo are a very reputable automotive engineering consultancy and R&D firm so I'd be guessing that they wouldn't let erroneous articles get out in the public domain.

So standard diesel or performance diesel
