Hi, long time, my 2004 955 S has numerous lights, bells/whistles, going off, ... I am so new at this - I would like to see if any can advice me on which scan tool to purchase? I am just trying to diagnose all the errors and perhaps 'reset' any? I understand many of the alarms can be manually adjusted, so I'm just putting a feeler out there - any advice for a beginner to diagnose the seemingly endless problems? thanks so much in advance - if there is another forum this should be in, my apologies.

 

with a PC or a standalone tool?
