"If your car does indeed have a leaking shock absorber, it won't cause any warning lights to come on,"

I should clarify this statement. If the strut doesn't have an AIR leak it won't cause any warning lights to come on. Sorry if I confused anyone.

There are a few DTB's about various Air-Matic issues. Your dealer should be able to sort it out for you.

"I'll call another dealer and see what they say."

A word of advice. Whenever possible, try and stick with the dealer that sold you the car. If you bought it used, try to use the selling dealer for service issues. It may give you a little more leverage if problems arise. Good luck.
