I'm glad you dealer finally got it worked-out... Sorry I didn't see this post earlier...

The other posters were correct when they recommended that you try to get the DTC's (diagnostic trouble codes) from the OBDII (onboard diagnostics) or you can refer to it as, the master computer system...

If you ever have problems with the car in the future, ANYTHING... all of the data from the multitude of sensors built into the car will log specific DTC's that will almost always tell you what the problem is... Unfortunately you most always will need the assistance of the dealer because they have the computer interface that reads the codes...

I have posted all of the DTC's here on this site, so if you have problems with the dealer mis-diagnosing a problem, or not making a repair correctly, you can ask the dealer service manager to show you the DTC printout and refer back here for the proper related problem code...

Unfortunately, these cars, as most cars these days are manfactured so the only people who can work on them are the dealerships because of the related computer diagnostic equipment required by the manufacturer... This insures that the dealer keeps making $ on your repairs...

But with the Crossfire, most Chrysler dealerships do not have qualified personnel (Mercedes trained) to be able to diagnose and repair the car on the first time... Most are using the hit & miss method...

When your warranty expires, you are best to take the car to a qualified MB service department or independent MB mechanic with the StarSystem computer....

Happy holidays....
