cold start engine knock and tap... help

[THIRDGEN87]

ok guys. im lost on this one. the coldest night here in nj all year. temp is 25. i go outside and start my car. vanos and a tap knock sound while car is running. ses light came on right away. plugged in my mac obd2 reader and got codes p1519 , p0325 , p1175. i looked up all these codes and know what they mean. but does anyone know, or have had experience with the similar codes all at once. p1519= cam position actuator , p0325= knock sensor , p1175= fuel trim actuator. just tring to figure out what needs to be done or changed. my car always had the vanos noise. now its just a little louder. sound seems to be coming from the passenger side. thanks for your help / knowledge in advance

Are you using a good winter oil?

[THIRDGEN87]

honestly, i dont know what is in there since i just bought the car. but i do know it is full synthetic. last oil change was done by a reputable local indy. he is a certified bmw tech. i know this by the sticker on the windsheild. but it isnt due for another 1900mi. should there be a different weight. and would this cause the car to run rich and knock? thank you.

Mine does it to be honest, but I know it's the oil (which I need to change as a matter of urgency LOL)...

Okay Misfires are ignitions coils thats are bad, if you chnage them out also change the plugs... As far as oil I would ask my person that chnaged the oil what weight was used, also double check the oil level.

I had the same problem. It's your front intake gasket... See item 11 below....
