Hello everybody,
First of all sorry for English, but I do not speak German at all ...
I'm here because I'm facing the same problem. I bought 4 springs at BMW two mouth ago to put back original my Z3M.
In the back no problem, but the front is abnormally too high, the car seems ready for the next Dakar rally. Naturally the assembly has been checked and is correct.
My BMW dealer order the front springs using the OEM number corresponding to my car, 31 33 2 228 474.
So I'm very surprised having received Eibach spring as OEM parts, as you can see in the photos below :

I'm wondering if the original parts are not out of stock, and the Eibachs would be parts of remanufacturing. So 14/17 should means built week 14 of 2017 ?
Or simply pieces badly referenced by BMW and dedicated to another model ?
Thanks for your help Z3's enthusiasts !
