m5 f10 exhaust

[neeks007]

i have a 2013 m5 f10 i have this slight noise coming from my exhaust it sounds good no misfire or codes but it almost sounds like a puff of air comes out every 3 minutes no smoke or anything it's just a slight puff noise. thats the best i could explain it lmao anyone have any ideas without a code popping up or anything like that it's also only at idle

Sounds like a misfire to me. Have you changed the.plugs/coils?

i have not, but i have had the car looked at, inspected and drove with everything coming back as good it's just odd cause it does it once maybe every minute

I know it's the Windy City but..(kidding. Strange one, bad gas maybe, pour a measure of gas/injector cleaner in at your next fill up see if that clears it up.

I use Redex the original gas/injector cleaner myself together with 99 V Power now but it may not be available your side of the pond.
