EML & traction control lights. Error codes:P1189 P0601 P1542 P1477 P1188 P1250 P0150

I bought my 99 328 in September right before winter came as my only form of transportation at the time was my gsxr600. Bought from original owner. 129,XXX curently. MN. Had it inspected at Camp BMW they came back saying all it needed was coolant & brake flush as well as new tires. Did see on the Carfax that it failed emissions and then passed some time later when re-tested. In December I started my car and the EML and traction control lights came on turned the car off let it sit a few minutes turned it on lights were gone and all was good. Then in March it happened again, and again, and again. I checked the codes today and had the following:

I've done some reading through forums and have already cleaned my MAF and all connections as well as checked the oil separator to dipstick hose and it seems to be good. For all I know that might have fixed the problem as the lights come on only when starting and very intermittently sometimes same day some times weeks. Im trying to sell for something newer so I can use all the help I can get. I have attached pics to help. Probably too much info but I figured the more the better. last seven of vin#KG08559

You are looking at at something that affects fuel delivery to both banks and that brings both the fuel filter and pump into the discussion. Start by performing a fuel pressure test or just ahead and change the fuel and air filters.

I don't know how to test for 02 sensors but since you engine has over 100k miles, you might as well change the pre-cat ones first. BMW recommends changing them at 100k anyway!

Seems you also have a dme error/faulty, but I think resetting adaptation values after replacing the fuel filter and clearing all codes should set it right...

I had something similar happen to my 323Ci back in December. I reset so many things and started to guess at what it would be. I replaced the throttle body and then eventually replaced the engine wiring harness. However, my car went into limp mode whenever these lights came on.
