I'm looking to store an N54 powered 135i for up to 2 years, it will not be insured so the most I can do is pretty much drive it up and down my driveway. I planned to start the car every two weeks and let it get up to temp and just kind of roll it up and down the driveway. Wiil this be sufficient? Additionally, I was looking at using some fuel stabilizer. Though I am not sure if that is an issue for the Piezo direct injectors on the N54 motor. Ideally I'd be able to insure it and just drive it, but due to some unforseen circumstances I just cannot afford another car on my insurance plan.

You can use fuel stabilizer but I'd never recommend leaving it completely un street driven for 2 years. Maybe just throw insurance on it for a month in the middle once or twice. Ideally it should get up to temp and the trans too. Gears gone through, etc.

You have to make sure to let the oil get all the way up to temp and trans if auto leave in in drive for a bit with handbreak up. Important for oil to get to temperature and evaporate moisture and fuel.
