I recently moved from TX to IL and on the way i had to tow my SAAB 900 Convertible from Corpus to Dallas. I rented a U-Haul tow dolly and when these things are unloaded such as the 10 mile drive from the U-Haul place to my house it just about beat the car to death!!!! (I could feel every bump the tow dolly hit through the steering wheel). Well when i got home i unhooked and my wife went to the shops, she called me right ater she left telling me she had an SRS SYSTEM SERVICE URGENT message in the message window............. Well it has been there ever since, 2000 miles and a week later its not going away. Im wondering if that stupid tow dolly activated a rear crash sensor or confused the system somehow. Any ideas?? Going to try disconnecting the battery for a bit tomorrow, but ill be lucky!!!
