Hi everyone,

I have a stock 2011 335i with the N55 with 88k miles. Car was running perfectly (even in recent very low temps) until I started it up running errands and got a CEL with the above (2DCE & 2EOF) codes. I had to drive 15 miles home - car drove totally fine, idled perfectly. Didn’t rev above 3k.

Haven’t driven it since and get no noise upon unlocking, like some people have. With that said, when I turn the ignition on, I get a singular “click” from under hood, and get the same click when I turn the ignition off.

Going to the mechanic in the coming days, but has anyone experienced the singular click? Lots of reports of chattering, 2-3 seconds worth of clicking, etc.

Hoping my endurance warranty (ugh) covers this. Thinking it’s the valvetronic motor or the eccentric shaft?

If anyone has experienced please comment below. Thanks all!

For anyone else experiencing this - it was the valvetronic motor that gave out. My shop replaced that (eccentric shaft actuator was the technical term) and did the Valve Cover Gasket (as they overlap) for $1400. Hope this helps those of you in the future!

Thanks for the feedback. I have heard that Valvetronic can be an issue.
