need me some aural pleasure...
2013 r172 SLK55 AMG, 28000 miles.
Fun toy, dropped the top for the first time today (along with swinging the tach north of 4000 RPM for the first time), however the exhaust note was boring and the thrust was very strong, but I was expecting more on both counts.
One flashlight, one screwdriver, and 2 minutes later I determined that the actuator on the right side of the exhaust tries its best to sync up with the left, unfortunately it appears to have suffered physical damage such that the shaft is not connected to the stepper motor. It freely opens and closes under the slightest touch while the actuator whines and fusses ineffectually.
The left side doesn't move at all during with the Smartkey in position 1, nor do I hear any sounds, my assumption is that it is fine, just waiting for the crippled right side to sync up. Probably a bad assumption, but it is my starting point.
Short version; left side flap makes no sound and doesn't move during the start/test portion. right side can be opened and closed by hand with no resistance, independently of the machinations of the actuator. it is obviously no longer connected to the actuator, but the shaft shows no indication of wobble, so I am hoping it is a connecting piece/cotter pin deal that I can easily repair.
I do not have a lift to get a good look at the mechanism, so if someone could point me to an exploded diagram of the actuator, tips on getting it out or repair, etc. it would be greatly appreciated!
The common problems I found on the internet search I did were about totally dead units, not a disconnect between the shaft and the flap.
thanks and so forth!
