Mein Auto: E39 touring
Pumping/Pulsing sound in rear engine (passenger side)


I did a search of this issue on the forums but I can't seem to find another noise post that is similar to mine. I noticed a rhythmic sound recently and it only happens after the engine is warmed and the car's been driven a few miles. It's most noticeable when I'm idle. The noise is coming from the rear side and it sounds louder the closer I get to the passenger side wheel.

I had a pre-cat o2 sensor code come up a few weeks back but I replaced those. No other CELs at the moment and I'm getting fairly good gas mileage. Any suggestion is appreciated.
