The N62 V8's valve stem seals harden and shrink with heat cycles, letting oil drain past the valve guides into the combustion chambers while the car sits. Owners see a large puff of blue/white smoke on cold start or after a long idle, plus steadily climbing oil consumption. The f… Repairs typically run $2,500-$6,500. Severity: high.
The N62 V8 routes coolant through a metal transfer pipe that runs through the block underneath the intake manifold and valley pan. The O-rings sealing that pipe into the timing cover harden and fail, dumping coolant internally where it escapes through a weep hole at the front of… Repairs typically run $1,200-$5,000.

The E65/E66 replaced the mechanical handbrake with an EMF electromechanical parking brake whose actuator motor and cable puller sit in the trunk, under the carpet toward the front of the trunk floor. The actuator uses plastic drive gears that strip, and the unit's location makes… Repairs typically run $300-$1,500. Severity: medium.
The E65/E66 7 Series is notorious for electrical gremlins and module failures. Common issues include iDrive system crashes, CCC (Car Communication Computer) failures, body control module faults, and random warning lights. The complex electrical architecture has poor reliability. Repairs typically run $500-$4,000. Severity: medium.
The E65/E66 uses the ZF GA6HP26Z (and GA6HP19Z on some variants) automatic. The wiring harness for the internal Mechatronic valve body exits the transmission case through a plastic sealing sleeve on the passenger side, above the fluid pan. The O-rings on that sleeve harden and th… Repairs typically run $400-$1,200. Severity: medium.
