First off sorry if this is in wrong section, I'm new to the forums and new to owning a BMW.
So I bought the car yesterday and obviously everything seem'd fine until I set off home.. Just before I got on the motorway I heard a weird noise kind of a scraping noise exactly like the exhaust has fallen off.
So after pulling up and seeing everything was fine I set off again.. Then it happened again just randomly for a couple of seconds.
Today it started yet again then went .. after about half hour it come back and didn't go away.
The best way to describe it is like I said before, it literally sounds like the exhaust is scraping on the floor but it does it randomly, no set speed/gear only when I'm moving even if I dip the clutch it still does it but only when i'm rolling.
I took it to a garage and remove the back part of the heat shield and it stopped it for a while but I've heard it once or twice since that.
Like I said, I'm new to BMW's so any advice is highly appreciated !
Car is a 2001 318ci se.
