REAL nice..
When I sold my E38, it gave me peace of mind that teh new owner inst of me had to face with the display unit replacement because when below 5 degr celc both speedo and rev counter worked bad..
Now I have the same with Rev counter on the E34!! too less revs and "shocking"needle !!! untill 60 deg engine temp....
Plus the BC temp show -32 or so.. Not exactly right for good ol Holland..doesn't become normal when car heats up either.. other function work normal..
Guess there's not much to do about it, lot of different models BMW have this acc to my experience. bugger...
