Consumer Review Video - 2007 BMW 525i 3.0L 6 Cyl.

Common problems and easy repairs on a 2007 525i

The 2007 BMW 525i is a more difficult car to maintain than other similar models. In order to access the battery, you’ll have to peel back the lining in the trunk. This is a more difficult process than you’ll find on other cars. Accessing the cabin air filter requires more tools than it does on similar models. The petcock is located behind a panel underneath the vehicle. This can be tough to remove, as you’ll have to get underneath the car and have to deal with falling debris while removing the panel.

Not everything is difficult. To access the headlight, you only need to reach behind the housing for access, which is much easier than on other models. The engine air filter is also easy to access, as it only requires you to disengage a few fasteners. The power steering fluid reservoir includes a dipstick, allowing you to check the fluid level easily.
