lumpy idle and lumpy 2500rpm. Occasional popcorn. Worried about cam. Logs included.

05.5 BRM with 117k miles, original cam, 505.01 every 10k or less.

There was some minimal wear on my cam at 85k miles a couple of years ago but we had no running issues so I shrugged and let it be. Fast forward to now.

At idle, when cold or warm, there is a notable occasional lumpiness, or a miss, or whatever you'd like to call it. It very lightly shakes the car. Doesn't matter if it's in park or neutral. That same lumpiness/shakiness is pronounced around 2500 rpm but the rest of the range is pretty good. Once every couple of minutes I hear the "popcorn" knocking sound others have described, which lasts a couple of seconds.

I'm pretty concerned my cam is on the way out, and I plan to lift the VC again sometime this week and check it out. I ran the VCDS tonight but I'm not sure what to make of it, so I'm copying my logs here in case some guru has an idea.

I'll be checking the cam soon - now I'm just wondering what setup to go with since I know there are a number of options.
