SpenderE46. I was wondering what oil you used. In your previous post
on what oil to use, I forgot to ask you what oil you were using. Also, what
is the mileage of your car and how many miles on your current oil? These
factor all in when an engine makes some sort of tapping or ticking noise.
Some engines are prone to this all the time. Does this happen when cold?
I don't think it's anything to worry about unless it's very loud. Bring it in
a BMW shop and have them look at it.
