Description
If you are here, you probably know or read in the BMW forums that these O-Rings on the DISA valves deteriorate over time. It causes some of the dreaded vacuum-related fault codes (P0171 and P0174 sound familiar?) Replacing the O-Ring is a very inexpensive way to start. Even if your problem ends up not being the o-ring, you will have peace of mind of having done something that eventually needs to be done. A BMW DISA Valve retails for $380.42. Replacing the o-ring is a fraction of that.
As a BMW owner and a DIYer, I did this job myself. It was a long research to find the correct o-ring because there is no part number for this o-ring for BMW's made after 2001. In the old DISA designs, the ring came separately under part number 11617504543. In the newer designs, we have to scrape off the existing ring and fit a new one. Therefore, the precise size, shape, thickness and material of the o-ring becomes very important. When I replaced my o-ring in my M54 engine, I did all the research and found the one that works. I bought in bulk and selling it to the DIY enthusiasts for a fair price.
This is an all-silicone O-Ring. Silicone has many superior qualities to rubber for performance under heat, compressability, flexibility and resistance to abrasion. All the situations this o-ring would be put under in other words. Here are all the ways this silicone o-ring is the one I preferred to use:
- The backbone of silicone contains silicon and oxygen, while the backbones of most of the other rubbers contain carbon-carbon bonds
- Silicone is more resistant...
