330i exhaust
So BMW have changed the map on the 330i’s recently, I had a loaner (build date March) and it burbled quite abit in sport plus. I got my 330i last month and it only burbles on start up, I thought maybe it was just the loaner but I then met up with a colleague who has a July build 330i and that burbles the same as my loaner.
So it looks like bmw did a stealth tweak to them towards the end of the year.
