2003 E320 Maintenance
So i recently got a 2003 E320 with a good amount of miles on it. I am needing some help setting up a list of stuff that should be changed like a cabin filter and etc (car still has original dirty filter for 11 years). So if anyone can pitch in and make a list I would greatly appreciate it.
Then there's HID and LED lights..
But, in actuality, to add to what Lemon covered (which is basically everything I've had to do to my car in the last two years of ownership), make sure your mechanic checks the tensioners/pulleys when he goes in and changes the serpentine belt. The plastic housing on them can often crack and leave you stranded - cheap $18 part but vitally important. My idler pulley was bad and causing a bit of noise on start up during cold weather, glad Sandor at StarTech caught how close to failure it was. Other than that I think that pretty much covers everything.

First place, there is no such thing as "Turn Signal Fluid", it is "Blinker oil" and even if your dealer says it needs to be changed every year, you really only need it every third year as long as you keep the level within 0.01mm (Measured at 32.6875 deg C)
By the way, it has to be the blue blinker oil (Spec 22666555.123457), not the older orange blinker oil (Spec 22665556.123456) but some use the green BMW blinker oil (Called turn signal fluid)
