Me again lol..

Hey gang, can anyone else with an '01 E430 tell me if they have a "power reserve" once they turn off the car? I have gotten mixed answers from mechanics etc. Some say its an option? That just does not make sense to me. Most companies either sold their cars with it or not. If my car does have it its not working, I talked to one other Benz employee who actually owns a twin to my car and he says he DOES indeed have it.

So I guess the core question is, if my car is indeed supposed to have the reserve what possible culprits could be keeping it from working? I have checked all fuses and I have read my owners manual cover to cover, the mechanic also said the ignition switch might be the problem and that you also should be able to program the duration of the reserve if it is indeed installed.

BTW, by "Power Reserve" I mean the ability to still run the radio, power windows etc. Once you turn the car off and remove the key usually for a period of approx 30 sec -10 minutes. As long as no doors are opened.

Thanks again guys.
