Got a brand new Denso in it. Replaced the ground wires to the battery and the supplycable for the alternator.

But it charges with 100Amps. way too much for a charged battery with nothing on. Maybe it is the smart charging that gives the trouble.

Do you need to reprogram the battery with a ECU diagnostic when you replace a battery on these cars?
Have heard that BMW and VW will charge at max if you dont reset the computers after disconnecting the battery
