Cold Weather 'Service Engine Soon' - Help with Errors from INPA

[TiminIndy]

I'm really hoping I don't have to replace the MAF - not cheap! Not sure if anyone can make anything of those MAF values, as well as other values listed under the errors (TCO_ST, TIA_ST, N_32, etc..)

If it is the MAF don't buy a wing wong MAF from eBay or Amazon. By a genuine Siemens MAF for the X.

Using the BMW PNPC tool, the best price I found for OEM was $337 from the BMW Parts Store. ECS Tuning has a Bosch replacement for $140. Bosch isn't exactly "wing wong", right?

For my Porsche, I needed to replace the relay for the AC system. Order a "Genuine" Porsche relay and it came in a box with the PORSCHE logo on it but when I took the relay out of the box the relay had Bosch logo on it along with Made in China on it. Even BMW ignition coils are now made in China.
