that's the engine code i received on my scanner with explanation from scanner. do you have any thoughts or ideas on what could be the cause of this. i recently did an oil change on the vehicle and switched to 5w-40 liqui moly . could that be a cause of the rough cold start?

Have all of your pervious issues been properly cured, or is this a case of deferred repairs adding up? Engine oil is used as hydraulic fluid in BMW variable valve timing system.

the vehicle hasn't had any other engine issues, and there's no check engine light. the vehicle has been having rough cold starts, nothing drastic. i honestly thought it could be spark plugs, not sure if they've ever been changed. im the second owner of this vehicle and haven't had to do much besides change the brakes and rotors, oil change, and i had a CAS issue. I basically plugged in with my scanner thinking i would see a cylinder misfire of some sort but instead got a camshaft control intake code for intake 1, and 2.

Theres no check engine light so im praying its intermittent, I've cleared all codes and am hoping it doesn't return. However im trying to figure out what could be the cause of this, 3 days ago i changed the oil to a 5w-40 liqui moly which really shouldn't have done anything wrong. issue is only on cold start .

I am not smart enough to differentiate YOUR previous issues from YOUR engine issues. Did you fix them or are you too smart? Is your LiquiMoly BMW approved? Of course, correlation is NOT cause.

You sure the fault code is 2A79? You did an oil change. Did you confirm your oil level?

@baby unicorn. yes the two codes are 2A79, and 2A75 the scanner specifically describes it as a variable camshaft timing control intake cold start. 2a79 for intake 1 and 2a75 for intake 2. I've monitored oil level every day through idrive and its saying its fine.

My wild ass guess (no experience with these specific V8’s) is that there’s something clogging the cam actuators.

Now there are two codes?!?

Previously I asked about your incoherent post with some weird words, and you stated this is what the scanner told you. Re-reading it, I was confused by the ‘also for intake 2’.... because THAT isn’t a code iver ever seen.

Now you say there are two codes.

Buy a frigging keyboard and type out coherent posts...this texting crap is useless.

I’d spend some of my time on what I think your issue is, based on now TWO codes...but if you cant take the time, why should we? you’ve got a vanos solenoid/camshaft timing issue. My guess

I see that you have 2012 50i same as mine except mine is 2011

I had similar issues last year

Dealer said to replace spark plugs and coils as they were original 8 years old.

I agreed and now my car runs like butter.

Try it , if your 2012 has original sparks and coils. No harm done.

He probably doesn’t know how to change plugs or coils on a BMW. “Derp derp derp, I’ll do it just like it did my monster cool Chevvy..”

rough cold start

Have you checked your vehicles for recalls? I have no idea if this is related. https://www.bimmershops.com/blog/bmw...t-timing-issue
