Hey Mark,
They can't find a problem with it. I know it has something to do with when i go into fifth gear my car goes into full time four wheel drive and something is heating up, and causing the lovely burning oil or grease smell through the cabin, then the four wheel drive light comes on. This only happens when i have to spend long periods in fifth at high speed. Can't wait for Mount Gambier, how about you, have you seen the post for the meeting this weekend.
Catcha next time your out cruisin.
