Hi everyone I'm new here...Just bought blue 01' 530d SE AUTO Saloon with 95k miles on it...there wasn't service book in a car so I don't know what's the story...I've talked to mechanic,who usually fixes my cars, he told that need to change every possible filters - engine oil&filter, fuel filter, air filter, and crank case filter on rocker cove(?)...I don't know what to start with? what about gearbox oil? Any suggestions everyone? Happy New Year!!!
