LOL the notorious tick! During my two years of ownership on a 2012 c63 with super low mileage I had 3-4 occasions where I started the car cold and it had a very very loud tick that sounded like I had lifter problems. It would always go away right as the oil warmed up and was told it was pretty normal for that motor. Very unnerving.

Any long term concerns or engine concerns?
Are there any long term concerns with the c63? Was looking at a 2020 base c63 or demo 2018 c63s. When I was researching e63 wagons from 2017/2018 there were posts about a not insignificant number of engines being lemon lawed. Isn't this essentially the same motor? Any other pricey bits to be concerned about such as the tranny? Thanks

Reading through many pages looks like the engine itself is pretty reliable? Main issues seem to be unprotected radiator getting damaged, coil packs, and start/stop cutting power? Has anyone fitted a mesh screen for the radiators? I know that's gonna cut some airflow but not sure if I feel comfortable with tiny pebbles causing $1800 in repairs.

I'd be mostly concerned with the under hood electronics. All the various sensors that are exposed to very high heat, over time they will fail. Not a matter of if, but when. Take the MAP sensor for example - lot's of people in the last year have been getting the one on top of the intercooler(s) replaced, myself included and I only have 15k miles. The M177 is extremely stout, and I wouldn't be concerned with internal issues with the engine itself. But the sensors feeding it data... not so much confidence in their longevity. Another sticking point is the transmission as they're known to slip under high torque when tuned beyond stock turbos.

MAP sensors are cheap, it’s the annoyance of having to take everything apart to install a simple part. The MAP sensor on each of the IC’s are a pain, requires partial removal of the intercooler - I’d say 2-3 hours labor.

Living in Texas, I always pop the hood in my garage to let the heat escape after spirited driving (rather than bake the electronics in a convection oven).

C63 with tune is my DD, I do 40 000km/year, all weather, daily highway 150+MPH... no oil consumption, nothing.. I have nearly 100 000kms now, planning to keep it 2-3 more years

What do you guys use as a guideline to see if the car needs the hood opened to let out some heat? I haven't driven my car "hard" yet but what would a good rule of thumb? Thanks!

LOL...hey man what's up. I hear you and I also remember on the older JDM turbo cars if you had been out beating on it...it would behoove you to drive around easy to let the turbo's cool before shutting it off for the night. It has gotten better with these fans that will kick on after you shut off the car but popping the hood would help with the issues discussed in this forum for sure.

I don't see the need to open the hood on this car. If the engine and turbos are hot, the fans will run for several minutes and blow out most of the heat. You can feel it just standing next to the car and how the air gets cooler and cooler. I wait with closing my garage door until the fans stop, so all the heat gets blown out instead of trapping it in the garage. My previous 2013 RS5 was much worse with heat. It ran the fans for a little bit, too, but it literally turned my garage into a sauna from all the residual heat. I had a couple of cooling hoses that clearly got brittle from the heat after a few years , but honestly with the C63 after I let the fans blow out the hot air, the residual heat doesn't seem to be a big deal. My really hard drives are in the remote canyons, so the 1+ hour highway drive home serves as the cool-down lap so to speak.

Gotcha. I am located in SoCal and lately the temperature here has been on the higher side for me, tho I am sure it's nowhere near as high as the temp other states experiences, but I wanted to ensure I am not unintentionally causing any unnecessary heat built up due to the recent abnormally hot days here. The residual heat hasn't been horrible for me too, but I haven't had a good opportunity to put the car through its paces yet.

Soft limp is the sh*t one because it won't throw a code at all and is triggered when your battery is run down eg. leaving the door open for a very long time during a detail etc.
The only way you can tell if it's in this mode is if your engine display is not hitting 500HP.
Is yours reaching 500HP (and over) on your command display?
PS: More info on it here.

How do you manually release the rear parking brake ?
Also, after driving the car really hard, there are other parts that need to be cooled down besides the engine. Specifically brakes and tires. If you haven't seen the front tire temperatures show red or at least orange in the TPMS display then you haven't driven the car hard yet. After a good run in the canyons at least one of my front tires is in the red, partly from the heat of the brakes, and it takes several miles for it all to cool down. At the AMG Driving Academy they made us manually release the parking brake every time we got out of the cars, so the pads don't imprint on the rear rotors and we left the engines running to keep the fluids circulating. After a quick spirited drive before coming home I often leave the car idle for a bit once I pull into my garage before turning it off for the same reason to let the oil circulate a bit more, and if the brakes are still kinda hot, I release the parking brake.
