W213 E63S Ticking Noise - Fixed
Thought I will share a quick fix for something pretty annoying; ticking noise (similar to a breaker clicking fast on and off), based on my research it exists in a lot of the M177 engines.
The noise comes from a failed Purge Valve, sits in the driver side of the engine bay right behind the headlight (see picture), the valves can fail but not enough to through a code. What you will hear is a fast ticking noise typically in idle, very annoying for sitting at a light, or talking with some friends outside the car and having it constantly tick. Also, notices the auto start stop function started working again once I replaced the part, not that anyone cares about gas mileage with those cars haha
Part Number: 213-470-69-01-64 (link: https://mbparts.mbusa.com/oem-parts/...e-213470690164) Might be different for other 63 vehicles.

the noise will come back, many dealers will just say "normal" and move along

Is this excessive or normal? I never noticed it this loud before. Even my family asked what’s up.

@PeterUbers thank you for those links, seems this is not urgent so I'm not going to rush to the dealer for this and will wait until scheuled service. However if my other "reboot" thread happens again I'll be heading in early.

I always wondered what caused this sound (I had it in my W212 E550 since I can remember), and I just replaced my purge valve and noticed it's gone. It also elimated a rough idle I've had for ages that I could never track down the source of. It just recently caused a check engine light (it was stuck open). I picked up the part for under $15 on Aliexpres shipped (for the W212 E550) and had it installed in under 10 minutes.
