Just had my Microfilter changed at the time the car was serviced by Wothnton BMW. Charged me $248 but the micro filter indicator kept coming on everytime I swich on.
The wothntn BMW bloke said he couldn't reset the light but assured me it has been replaced. I noticed some dust particles flying out when I turn the AC on. Took it back to the dealer and now he wants an additional $275 to do an AC system service. 165 for service, $80 for regas and best of all $30 for de orderise. Anyone had similar experience with the Micro filter or AC service.
