On the F series platform, you cannot buy an MPPK off eBay. The FSC which are generated are tied to the VIN at the time of purchase. I would be weary of the same on an E series platform.
How did you get the original MPPK? Again, I’m not sure why you don’t tell the dealer you think you lost your PPK as part of their update.

Yeah, so the original owner flashed and I believe he used a 3rd party to have it flashed - perhaps an MHD bin file or something like that, not 100% sure - but it was not a dealer that coded it. One of the services online (sf*********) says any software update will remove the flash, and I believe that's what happened. It was an independent mechanic that did the software update this time.
I've seen that e90 mppk's are NOT tied to vin's, unlike the f3x ones. I'll update this thread accordingly based on what happens here. Thank you!
