16 r with 3k miles. Was mixing it up with a bit of spirited driving. (Btw the m5 is a pretty fast car) and when I pulled up to a light it started to run rough and the exhaust note sounded like I was missing a cylinder. Almost felt like I was going to stall. No cel or other indication of a problem. Fully expected to see a puddle of oil or flames from under the hood nothing. Restart and it was fine. Anyone else have this issue?

 

Wow, that is a little scary. I haven't heard nor experienced anything like that. Curious to hear from others.

 

sorry, hasn't happened to me, so can't help you there. But yea, the M5 is a monster of a sedan.

 

. He had a go pro mounted on his windscreen I may be on YouTube tonight. He had a view from behind

 

Here's the opposite angle OK, sorry for derailing your post...back to your mysterious issue.
