The Xk didn't start this morning. Alll the lights worked and everything, only got the clicking sounds. It started with a jump. My ESP/BAS light has been on for a week or so and now after this morning the "service 4wheel drive system" appears. There are no codes. I know that this is a horrible question to ask but was hoping someone could give some input. I've been in clinicals for awhile and will continue to be till next year, so I'm hemorrhaging cash and not taking any in. Taking it some where for them to diagnose isn't an option now. Any advice would be appreciated
