Hi everybody. I am a brand new, first time BMW owner of a 2005 545i with a SMG.

I test drove the car and everything was great. The car is in great physical shape and is very clean. I bought the car and drove it home without any issue. Once I got it registered, I took it out for a half hour drive and everything was great. The next time I got in the car, the CEL came on and gave an INCREASED EMISSIONS warning, and the car went into TRANSMISSION FAILSAFE MODE. The car starts and runs fine, but it is in neutral and will not go into any gear. So my excitement over finally owning a BMW 5 series was pretty much killed.

I checked all fuses and they appear to be ok. I climbed under the car and there are no leaks or any obvious visual problems. The previous owner told me that he had put in a new battery. I checked this with a Foxwell scanner and it did say that a new (lead acid) battery was put in and registered to the car in May, 2019. The scanner also gave me some codes. It has code 29FE (DME: Secondary air system) and 4F6F (SMG: Hydraulic pump activation).

PLEASE HELP! Any tips, ideas, things to check, direction to go would be greatly appreciated!

Thanks for any help you can give me.
