Thanks Guys... i have called Naidu. He told me maybe the microfilter + something he will check for me on next Monday ~~appointment already made...
My case is the aircon take long to cold...when hot weather 30+c will take about 5-8min to get cold... also my air blow out @ No1,2 is not strong seems like no blower at all... normally i have to turn on No.3 and Max.. not sure will microfilter help me.
Anyway check the last record.. the services of the air con already 3 year back... also i found that my Thermostat maybe need to change also.
How much will be the Thermostat cost me? again need to prepare some $$$ to meet Naidu...
By the way, Naidu only services air con only or he also do the services for BMW? heard he also driving a E34
