Basically, I'm having the same issue in my car...always thought it had something to do with diesel pumps, but it takes bloody ages filling up! The other day I tried filling it to the top when the light came on, and the pump timed out ofter 25 litres and 6 minutes
What's the breather pipe and how do you clear it? Car's still under VW warranty for 6 more months by the way, but if it's a simple job I'll do it myself, as it's too much hassle taking it down to be looked at...
Cheers,
Ash
