As the title says.But some problems may affect all series as well..For me (ranking from most important/common to less crucial/rare ) are:1) MID pixel issues2) Master key with remote especially the diamond type-expensive to duplicate and battery replacement is almost impossible without near-destruction of the key itself (why did BMW make it so hard for people to replace the battery?)3) Power steering leaks-expensive to fix4) Trans.fail.safe error message- scary as it sounds expensive to fix5) No folding wing mirror switches-should be default at least for local specs as Auto Bavaria ones were not cheap during E39 heydays.6)Heavy steering for me maybe not for some (my perdana and my ex-W203 feel a lot lighter)7)Wipers are positioned only for the LHD cars and no provisions made for RHD versions (E39 and E60 only. Not applicable to the F10 and E34)8) Local specs E39 (and most import specs) didn't come with rain sensing wipers/auto headlight and headlamp wash system.All are optional items that I know for the UK specs ones.9) Broken headlight level adjuster inside the headlights itself10) No wing-mirror LED-type indicator or the lack off this feature11) Feel free to add guys...:rock:
