Buying an E70

[bigbabyE53]

wwu123 is correct, failing batterys do run common in e70s. Make sure its been replaced with a proper BMW AGM battery (black battery). The tail lights are also common to fail (just like its older brother). Depending if you r looking at the N62TU or N52, each have their own problems. Oil leaks from the vaccum pump, oil pressure sensor, upper timing case cover gaskets are common on the N62TU (but what bmw V8 doesnt leak oil). The N52 has had water pump and thermostat failures along with vanos solenoid valves failing, especially if you do a lot of short distance/stop and go driving. But all of these problems are covered under CPO warranty, minus the battery. I also just replaced catalytic converters on an E70. Im sure its rare. Owner complained about a metallic noise when letting off the accelerator so listen for that too.
