I’m sorry if I sound like a broken record but I have been informed by several people at MB that it is not optional. The ‘voluntary’ aspect refers to MB’s action to volunteer to update the software on their Diesel engines in order to avoid being sued/fined by the German automotive authority.
The service contract (that must be signed before any service work takes place) incorporates the ECU update so you can’t sign the contract and also ‘not accept’ the update. By signing the service contract you give them permission to do the update.
