I don't know what I got myself into but it's overwhelming. Just picked up this 2007 525xi and it has all these codes. Can someone help? The car drives fine but would like to get it working correctly.
I let you know what to do on FB. You need to start checking connectors. We see it all the time. Owners get good deal cars but lack the knowledge and tools to diagnose what's wrong with the cars. It's going to cost you more to fix because of it.

You probably already got this advice too - reset all the codes and see which ones come back. Often, a car that experienced a low-voltage situation (aka "dead battery") will have set all sorts of nonsensical codes. If you clear them and they don't come back, don't get your knickers in TOO tight a twist.

I reset them a few times and this is what keeps coming back
You're being overwhelmed by all the codes but I assure you your main issue is you K-line fault. Find the bad wire or connector and fix it. The rest are normal codes and only require simple parts. Focus on the K-line fault and make sure your battery is good if not it needs to be changed immediately because once a BMW deems a battery not sufficient it shuts down modules.

IBS Missing won't help the battery much. Battery could be damaged already.
