Pir4te,
Please tell me you didn't rip out your fuel tank to respond to the "VF SV6 SPORTSWAGON petrol splashing noise and clunk when taking off" thread. Lol.
OP
I've noticed this a few times in 4 VE's since 2006. It's a little more pronounced when I hear it in my VF, but still no big issue. I'm not sure if the VF is more noticeable due to repositioning of the fuel tank, or a quieter cabin. Either way I rarely hear it and it doesn't bother me. Whatever Holden have done, the VF is much easier to fill past the first cutoff than the VE. I suspect the sloshing sound in the wagon would be more noticeable than in the sedan or ute, but I may be wrong. There is definitely no clunk though, and this may be completely unrelated. Bottom line is I've never bothered to mention this to my Dealer on any of my past five Commodore's because it is a non issue for me. It's an inherent trait of the vehicle and out of interest not a single person in any of my cars has ever asked about it. It's just not an issue.
IMO you should take the time to work with your dealer on this (clunk in particular), or another dealer if they are not responsive, and get the issue sorted. Bagging out Holden on line, for a very minor and questionable fault on a fabulous car, to me smacks of irrationality. JMO.
