Hi all,

Newbie here!

I just got a 2009 omega 9.5, dual fuel, for three months now.

Runs quite well. The AIr con is usually good, but starts making noise on a average to above avg hot day when turned on for 20mins or more.

I am going to take this car interstate on next weekend. So wanted some tips on this issue,before I embark on this long journey.

The car has done approx 70,000 k now
