I lost power in my 2000 ML320 because of a bad power connection. I entered wrong code 3 times to my MCS after the power was back and the MCS shows "WAIT" blue screen. I looked up internet and some said that wait 24 hours and it will reset so I can enter the code again. I have waited more than 24 hours and it is still the same. Any idea before I bring it to the dealer? Thanks.
