also, da kann ich dir auch nur aus meinem schlauen buch "BMW Series Service manual" dienen:
minimum 10-11 bar
maximum difference between cylinders 0,5 bar
Note:
the compression gauge reading should increase with each stroke, and reach its maximum reading in 4 to 6 strokes.
all cylinders should reach maximum compression in the same number of strokes. if a cylinder needs signifiantly more strokes to reach maximum compression, there is a problem.
on engines with EML, check that throttle plate opens when the starter is actuated.
aber wahrscheinlich gibt's da noch bessere hinweise.
