Try Tesco 99 - it has been repeatedly proven to be the best fuel in the UK, and is actually better than V-Power. :wink:

Sure, I'll give it a go in 80 miles time.

Good idea.  Did you ever get it scanned for any stored fault codes?

The last time it went to VW for servicing (about a month ago) they said that there were no stored fault codes.

Sounds similar to what I had been experiencing recently combined with a reduction in fuel economy.

VW checked it out yesterday and one of the inlet manifold motors had seized. That ties in with the link hurdy posted above I think.

Am I right in thinking that the inlet manifold motor is the same as the 'Tumble Flap motor', described in this post?: http://www.golfmkv.com/forums/showthread.php?t=24952

How did VW assess that this was the fault? Did they report any fault codes?

Yup, that's the one. :afro:

If/when that fails, it will definately store a fault code.

The wife was not happy with that comment  :shocked: and no, I'm the only one that ever fills it up.

Lets hope I don't get "computer says no..." from them then.

How much was it to replace the motor?
