Hey nughaud, my 2001 330CI within the past 3 months has randomly gone to fast blink mode. I had issues in my FR signal in the past, but apparently the deer I hit two years ago and follow-on work in that are fixed that issue. But recently, I realized it was the RR lights. I found dimming bulbs, and good bulbs tried there obviously did the same dimming, so figured it was the bulb holder part. I did a Google search yesterday and found your post, what I had was exactly the same problem you had.
I went home last night after work, grabbed a few parts from my workbench that I had on hand, and did the fix as you presented, took about 10 minutes of my time. Your solution worked perfectly.
Thank you for taking the time to post the explanation, pictures and solution. It saved me a little headache and time to diagnose and/or a trip to the shop.
