Mercedes Alternator Core - Bosch (Overvoltage Issue)

Selling a Bosch alternator core removed from my 2008 Mercedes C230. The battery alarm appeared on my dashboard, and testing revealed an overvoltage issue (15.6V) while the engine was running, indicating a probable fault with the internal voltage regulator. The alternator is manufactured by Bosch in Spain. Part Numbers for Reference: Mercedes OE Part Number: A2171540002 Bosch Part Number: 0124525055
