So, this AM, at around 0600, I took the turbo out on a bit of a hard run to define (better) what the hell the clicking was coming from the front left. The noise is now louder, and it most certainly is audible, at speed, when I load it up on a right hander... I am thinking the front left CV - no noise while going straight, so if it isn't a CV, it is something that is compounded when load goes onto the left front axle, so as they say, we shall see.
Break of Dawn money shot for reference... would be included, but the system isn't allowing me to post it.
Hey 2fcknfst. I know that they may be apples to oranges but I had a similar mysterious clicking with my 16 AMG C63s that truly droves me nuts for months. The sound correlated to rotation speed and availed itself mostly when making left hand turns. I took it in to several shops who told me that it was wheel bearings. Changed those and the sound came back within a week of driving. Then the dealership told me that it was due to dissimilar metals between my "aftermarket" wheels and OEM hubs and that they put a molly grease on it and that fixed the problem. The sound came back a few days later. They checked the rotor hats, etc that could have been tweaked. They thought that the aftermarket wheel TPMS sensors were loose and clicking around. They thought perhaps something was hitting the rotor slots. They finally took apart my brakes, removed my "Aftermarket" PAGID street/race brake pads, which had apparently cracked a bit and shifted somehow in the caliper and was contacting something. I'm not sure if our Porsches have the same issue but this took months to find so if it saves you some time, it's worth checking. Good luck.
Thank you for the notes - if memory serves, the C63 is only RWD, so no driven front axle, and I am able to correlate the noise to steering position and load.
My car is also very stock, other than being lowered, BMC filter and some GT3RS parts and clear lights.
I had considered a wheel bearing, but discarded the thought because as the car drove straight, no noise - only noise when turning right. Now, it is within the realm of possibility that it is a wheel bearing, yet, with other vehicles when a wheel bearing has gone, the noise omni present, in all conditions, so this would be new type of progressive failure.
And progressive it has been - initially, when it was in the shop, they said it was the top shock mount, took everything apart, lubricated it, put it back together and as I left the shop, no notable noise. It was back within a few days. This somewhat suggests that once everything was torqued up, it was holding whatever the source of the sound was, in place. This means, it has either loosened up, or more likely, the failure has progressed further to the point where it is audible under load and at speed.
If it is a CV, it must have been made on a Friday.
