I just did a top end rebuild on my '09 M8 HCR, jugs & pistons. Everything went smooth and it fired up on the third pull.
There was an "ECU 21" error code when it started so I shut it off after about 10 seconds of running. Found out the code was for a knock sensor failure but now it won't start, just pulls over like the key is off, (except the gauge glows red a little when I pull).
Any Ideas???
