Gearbox prop and all that is the same between them all.sure the car was originally a 520i.shouldnt be going near immobiliser etc.as ecu and ews will be the same.and the fact its an early e39 with 16pin round obd plug might make it a bit less complicated.gonna ask valdelis directly about it actually as he knows this car particularly better then anyone as hes maintained it the last 11years
