Bent Rod?
Uploaded BM3 Stage 1 on a stock car, less than a week later I got this noise today. Maybe 10hrs of run time tops
www.imgur.com/gallery/XIMGdxB Maybe it is something else? I have no lights on, car runs and drives- this happened down the block from home so drove it maybe 1000ft? Didn't drive any differently Checked codes, no codes. Last edited by Jonzny; 05-19-2020 at 12:41 PM.. |

Do you have the BM3 and are having some car issues or is this a simple query?

I did the rods on my E60 a bit before I sold it and also as preventative...it was a good call after it was opened up .
Looks like you have some bad juju my friend.

Damn, that is rough, man. I've heard so many good things about BM3's OTS maps. I guess it is still a one-size-fits-all solution at the end of the day.
Any signs of knock beforehand? Running smooth? Did you do any data-logging? |

I feel your pain. Went through a similar experience with my old Subaru STI (though that's a much cheaper and easier to fix platform).
I know it's still fresh, but you'll go through the grieving stages - denial, anger, depression, bargaining, acceptance. Please keep us posted. So many people hide their issues because of warranty concerns and they're trying to avoid keeping a digital footprint on the mods they did. With 60k miles, you're probably not in that boat. I have 52k miles on mine and your post is scaring me into staying stock. I may still use the BM3 platform to live monitor even the stock condition. I read another post that even a stock motor will have tons of minor knock events as part of the normal knock detection and mitigation strategy. Good luck! |

Obviously i'd recommend you don't modify, though these cars do have issues even in stock form. Have a buddy with a BMW shop he's told me numerous times these engines always go, and to get rid of the car, I didn't listen. Thought it was owners who poorly maintained them, guess that is not the case. My last two cars were M3s (E46 and E92, those also have their issues but all items that can be avoided with preventative maintenance/replacements, the S63 can't be helped unfortunately) |

I agree with sapphire, sounds like a rod knock. It's hit and miss with these cars . Makes me think twice about getting bm3 since I've seen more people complain about blown motors that use bm3. Then again a lot of happy customers that have bm3. It's probably just the luck of the draw my friend. Not a day goes by that I don't think if my engine will blow up regardless if it's tuned or in stock form.

For people that say the M5 is not reliable. It truly isnt the most reliable car but if you buy or drive one just look for good records on the car before buying and upon owning it drive it sensibly. Regular oil changes and limit your tuning to stage 1 or stock. I baby the hell out of my car, i personally do not want issues. Cool car but im done with BMW for awhile after this. There is a reason there are so many BMW rebuilders and shops |

I think the big issue with tunes like BM3 (even stage 1) is they seem to add significantly to low end torque, which is a big rod stressor. Sucks terribly that you've had this happen, but I'm not sure it's necessary fair to say the S63Tu is thus unreliable.
