2005 BMW 525i Failing Smog
Good morning! I recently Purchased a 2005 BMW 525i, she runs great 260,000 miles on the dash.

The car drives fine 70% of the time. Accelerates, decelerates great.
When I gun It, sometimes the transmission will seem to slip, rev all the way up and go into limp mode and say trans malfunction have transchecked at the nearest bmw service center.

The codes I’m getting are as follows:

P0700 Transmission code
P0175 Bank 2 too rich
P0172 Bank 1 too rich

4F95 ratio control clutch b-e
4F82 ratio control clutch b
4F85 ratio control clutch e
2882 mixture preparation bank 1
2883 mixture preparation bank 2
28B6 inlet camshaft bank 1 mechanically
51Ad message wheel speed from DSC is missing
296A Lambda position sensors before cat switched
299a error management EGS
299b battery sensor signal

Can someone point me where to start?

Spark plugs have been replaced on the car….I’m not sure what else needs to be done!

Thanks guys, this is my first BMW!
