    W211 Service indicator won't reset- "Calculating...."

    Hi, Just carried out a full service on my W211 E320CDI and would like to reset the service indicator. However, on the main dash display in normal mode it says "Service display not possible" and on the service reset page "Calculating....." How do I turn it back on?! Thanks Jon
