Alpina B5/B7 Supercharger problems
I'm new to the board and have read about the issues with the B5/B7 superchargers. I know there was a clutch fix for the earlier builds, but how has everyone's experience been with them since? As posted previously, I'm new to the board and am looking to buy a 2007 B7 in the US. BMW NA doesn't CPO the cars, so we're forced to go with a 3rd party warranty provider, and based on the comments I've seen...they can be very hit or miss. With that in mind, I don't want to get stuck with a B7 that blows its supercharger only to have to fight with a warranty provider to get it paid for. Any feedback on their reliability outside of the OEM warranty period would be greatly appreciated. Also, does anyone know what a new supercharger would cost? (I'm trying to compare it with the 3rd party warranty quotes to see if the risk/reward is worth it). thanks everyone.
