Not been serviced so far
From the service histories it looks like they have not been serviced so far ... they seem to be viewed by Mercedes in the UK as sealed for life? One the 2000 w210 the B service has just been done at 79k miles but no note of gearbox oil or filter change. Is it too late too save it or will an immediate change prevent problems - it still has the warranty for a short period so I guess if I detect a problem it will be fixed .. it is just a question of whether long term harm has been done.
Many thanks for your reply.
