Hi, I am writing to provide you with an update regarding my recent experience in sourcing a flywheel for my 2017 330e, which may be of assistance to people encountering a similar issue. After extensive searching, I successfully purchased part number 3 on my list, as I was unable to find the initial part number 1 at a reasonable price. The part I acquired, designated #9454556, is a flywheel with 122 teeth and has only 17,000 miles of use, sourced from eBay. Recently, my mechanic attempted to replace the old flywheel, but we discovered a critical discrepancy—while the parts appeared identical visually, the number of teeth differed significantly. My old flywheel (part #1) has 145 teeth, whereas the new one (part #3) only has 122 teeth. This incompatibility prohibits correct functionality with the starter motor. Also, I'm not sure about part #2 but I have a feeling that it would be same as #3. Thus, I would recommend adhering to the specifications provided by realoem.com for optimal results. I have included some images for reference, which may provide clarity on the differences. Thanks,

Thanks for the advice Dave.

Thanks Dave. I initially got those information from searching on realoem.com.

Hi, I am reaching out to inquire about a specific matter regarding flywheel parts for my vehicle. I have been investigating the following flywheel part numbers and would like to determine if they are compatible for the same flywheel: 1. 8681723 2. 8690203 3. 9454556 From my research, I found that part number 1 is applicable for vehicles manufactured from 2016 to early 2017. In contrast, part numbers 2 and 3 are meant for vehicles produced from July 2017 onwards. My vehicle, a 2017 BMW F30 330e (RWD, 1998cc, 185KW, 252HP B48B20A), falls under part number 1, as it was manufactured in April 2017. Given that these models are closely related, I am curious if the later part numbers (2 and 3) could also function in my vehicle. In the UK, I have been unable to locate aftermarket part number 1 at a reasonable price, but options for part numbers 2 and 3 are abundant. I would greatly appreciate any guidance or clarification anyone can provide on this matter. Thank you for your assistance.
