Disconnecting the battery will throw a whole bunch of fault codes. MAKE sure you've tightened the battery terminals... if you get a "reduced power" message it 95% because you didnt. as far as the other fault codes, usually they'll disappear after you shut the car down after a while then restart. They throw because you disconnected the battery.

IMO working on these cars a lot, bavarian technic is a waste because it's inferior to dealer tools and over priced.

Thanks for that. I have double checked the battery terminals and both were tight.
