I have a 2008 528i and I am hearing and also feeling vibration when the car is in Stopped state.... If the car is in running state, it runs smoothly and there is no noise.....It doesn't matter if the AC is On or OFF,, here is some of the work that was done in this car recently:

1. AC compressor changed
2. valve cover gasket changed
3. Tensioner

The noise is like if 2 steel plates are touching each other periodically and the noise is like "Than Than Than Than......."""

Can the vibration noise be related to any of the above jobs?

How shall I go forward for this issue? The car is out of warranty now, but the above stuff was done under Warranty within last 1 year, so the above should still be under BMW warranty....

Really appreciate your help, I am worried about this as it might cause further damage if I drive the care like this...

UPDATE: I went to dealership for the inspection, they didn't find any problem , except that the RPM at idle was low and they bumped it up by 150.... i.e. around 700, and things are looking better... but need to analyze for coming weeks...
