Yep, it is important to check, verify and adjust things, but equally important to change your operating fluids if you want your cars systems and components to last. My basic maintenance schedule for the Zed is: Engine Oil/filter: 7000 to 7500 miles or once a year. High revving engines need better oil protection.

1) Low/old transmission fluid, even though BMW says the ATF is "lifetime". Others have said this may cause shifting issues and recommend changing every 50,000 miles. I read that Valvoline Maxlife ATF is an excellent choice for the Z4 and plan to attempt that change this week.

BMW Z4 E85 TMPS tyre pressure warning light symbol - this will illuminate if the system detects that one or more tyres is not at the correct PSI.

Car stereo My name is Tom and I own a 2006 BMW Z4 that I just purchased I went to the BMW dealership in the Las Vegas area. And I inquired what it would cost and what it would take to put the navigation system in my Z4 and the nice gentleman in the parts department Ron Green said probably be better and cheaper to put in a aftermarket stereo in the car.

Does anyone else reckon the oil change intervals on the Z4 3.0i are too long? I bought mine in July from a dealer & the book says it last had an oil / filter change 14,000 miles ago in Jan '09. Yet the service indicator thing on the dashboard says I've still got another 4k miles to go before Insp 1. So that's 18,000 miles without fresh oil
