99 E430 Sunroof Intermittently Stops While Closing

[arnel]

My 1999 E430 sunroof sometimes intermittently will stop while closing. It will close about an inch then stop. Repeatedly hitting the button will eventually close it. This has happened about 4 times over the last year. I have about 68K miles on it.

Also, twice the sunroof pop up vent would not close when the button was pulled down. It was stuck in the up position. Opening the sunroof (which automatically shuts the pop up vent) closed it though. At the same time, closing the sunroof (I had to open it for the vent to come down) didn't work. I had open up the sunroof vent (which closes the sunroof) to get it to shut. Essentially both the close vent and close sunroof operation didn't work.

It was starting to rain at the time, so I didn't muck with it until I got home. When I got home, parked in the garage, turned off the car, turned on the ignition and the problem went away.

Has anyone experienced this problem or similiar "intermittent" electrical problems?


As a side note, once in a while (every 1-2 months) the stock CD Changer isn't recoginzed. The display shows "No Changer." Stopping and starting the car usually works around this problem. Anybody seen this issue?

I can answer the CD changer problem. I had the "No CD Changer" problem when I took delivery of the my 99 E430. The dealer replaced the fiber optic cable and the main unit. The problem went away (kind of). The technican told me that the fiber optic cable was bend somewhere during the installation at the factory. Therefore the main unit only received signal intermittenly.

However, I still experience "No CD Changer" maybe once every two to three months. I notice that when it happens the engine always takes a "bit" little longer to start.

Get the sunroof closed, and then activate the pop-up feature. As it comes to the top of the "pop-up" hold the switch for about 10 seconds or until you hear a"click" sound.

This should re-synch your sunroof.
