not manja...to be honest the reason why u hear alot of BMW has GB issues is that they are subject to abuse, long / wrong fluid change. Face it...these are ordinary cars (not M3) that is not meant to be high rev all the time. Plus remember M'sia is all year round hot climate so you can imagine the how hot the GB and internal fluid will get if its constantly subjected to high rev / high speed runs.
Just my humble opinion
