Possible valvetronic system issue
Got the following codes:
133B04 - Valvetronic system ; no adjustment possible
133E10 - Valvetronic system: deactivated , adjustment fault too frequent
CEL came on and after restarting the car, the CEL went away, and the codes were stored.
Cold start feels louder now, and I can feel the RPMs fluttering (nothing drastic) during the first couple minutes of start-up. I drove over 100miles after the CEL disappeared, and the light has not come back up.
Codes are related to valvetronic system, any one else have a similar problem/issue that was resolved?
I have a FBO 2013 F30 335xi with 50k miles.
