When I started the cf last week, it seemed every light on the dash illuminated including the airbag light and the spoiler deployed. The next day, all lights are off except for the airbag light and the spoiler retracted. My one mechanic when scanning the cf computer, said he received multiple trouble codes. He believed his software was not up to date. He suggested to take to a dealer. Took the cf to the mb dealer who will work on cf and again stated they were not able to "read" the cf computer. All that remains on is the airbag light. The cf is drive-able. One caveat brought up by the mb dealer, an aftermarket radio was installed over 2 months prior with no issues after that radio was installed. I'm told the SRS module is buried in the console or behind the radio. There is an SRS on ebay for $30. Given this hiccup of the inability thus far to read the computer, any suggestions to trouble shoot a cause if trouble codes are either numerous, not relevant or not reading at all? Thanks!
