What's the most ocd thing you do?

[TiAgX5]

I do the key thing too.

I also wait until the steering wheel gets into position prior to starting, wait the 10 secs or so until the SII display clears after starting before turning anything on in the vehicle (alternator output ramp up time), only then do I put the X in gear to drive off (the 10 or 15 secs of idle also allows for "no load" oil circulation in the motor/trans).

Prior to shut down....
Turn off AC (with fan running) around 1 minute before parking (warms up evap coil, minimizes dripping on front DS spline), all electrical item turned off when parked, then around 5 secs of idle before shutdown.

It seems to make a difference, the X has OE alternator and 3rd battery (13 yrs/200k miles).

And NOBODY but me turns a wrench on it.

No valet too (drives the CEO nuts).....
