SL500 Electronics go bad

I get a clicking nosie coming from the roll over bar, as soon as this apears i see the roll over light coming on in th dash. Within 5 min navi, radio, wiper go off as well as a ESP light comes on.

Any thoughts?

Thanks

You'd be surprised what faulty electrical signals can display and mess with on these cars. My starter battery was going out which would cause a shifting problem and the occasional error light. How these two systems are related except for the ECU is beyond me but getting a new battery totally cleared the problem.

Have AutoZone do their free battery/alternator check and see which is the problem. Keep in mind though that even though they may say "oh, it looks ok" make sure to look at the voltages directly. Even an 11.7V draw current may throw off the sensitive electronics in these cars and could indicate a problem.
