Last night my car threw an “ABS” light and “PSM off take to dealer” message. It continued to run fine and the lights went away when i shut car off and restarted. When I got home, I hooked up my Durametric and pulled these two codes:

P0103 - Porsche fault code 115 - Hot film MAF sensor
5525 - Incorrect data transfer with DME master control unit

I’ve been looking on the forums at people’s experience with the codes, but most get a boost error code also. I did not. I have ordered a new Bosch -8009 MAF, as I figure it is probably worth replacing the BREMI that has been in my car since I bought it.

Do you think the MAF could be the culprit?? Thanks
