I have a 2001 S500. Going through a lot of problem with it, but it is such a lovely car I don't want to get rid of it.

First of all, the Airmatic system is not working so the ride is too low.

Secondly, when I lock the car using the lock button, the lights are flashing rapidly and continuously at times. If I just unlock it and then lock it back again, it is ok. But, the siren/alarm triggers automatically at times.

Any advice? Please...............
