My Indicator light (91 300D 2,5) did not operate correctly either after replacing all of the GPs and the GP Amp - turned out the Amp I got from MB was bad -- they gave me a new one with no problem - then it worked correctly.
One or the other in your system has a problem -either 1 or more GPs are not operating properly or the Amp is not working properly. Good luck - at least the car starts!
