2012 C63 Coupe Edition 1 - Track Day - Is the engine overheating?
Took the car to the track for the first time today and could not run more than two laps before the water temp reached 280F and the computer automatically switched from manual to S+ and the car shifted gears dramatically slow. Outside temperature was about 74F on a dry sunny day. I then drove away and let the car cool down. 30 minutes later got back to the track and temperature went from 230F back to 280F and the whole thing happened again. Oil temp was reaching 200F (I was reading that of the AMG display option on the vehicle).
I am not a pro driver but have a reasonable knowledge about driving on a track and, since the car is pretty much new, I was conservative. Check engine light never flashed. Computer simply shifted transmission mode to S+ to avoid. Car has currently 5000 miles.
Is this normal? I assuming it is not...please help.
Thank you,

I have experienced the same thing. I made a post about it a few months ago. I had my car taken to the dealer and it stayed there for a week. all i got from them is an email saying that its a "known issue" and asking me to wait...

Join the the club. A number of us have experienced this problem during track events. (It's not all cars or all tracks.) Very frustrating. It is still amazing to me that our cars have this problem. I understand that the Black Series has larger coolers to address the situation.
Absent a fix, the only thing that I can suggest to help is to avoid engine braking--downshifting to slow the car.
Has anyone added a larger tranny cooler or oil cooler to deal with this issue?

That's not an acceptable response for me.

C63 isn't a track car unless it's a Black Series. Not enough cooling or brakes for serious track work. If you leave in sport, don't use the paddles and turn the ESP off you have a chance of completing a few fast laps. Start using the paddles and the engine/tranny will get hot real quick. Leave the ESP on and the brakes will over heat trying to protect you from yourself. I've gotten the water temp up to 250f in a few minutes just messing around on some mountain roads.

Something is wrong...saying it "isn't a track car" is not it. People track these cars regularly and have for years without these issues. Heck, most have modded to push these limits even further. Something is wrong, this is not normal behavior.

My car has also switched from M to S+ automatically. We had 20 minute sessions at a time on the track and I only had issues at end of the third session - Brakes getting a little squidgy and tranny switching to S+ mode. I assumed it was just to save the engine and/or gearbox from overheating and damaging itself so I had a chill session and all was good after that. Water temps were fine the whole day and oil despite getting warm at times >120degC, it quickly cooled down and was fine.
I have been totally happy with track performance of my particular car. I have had other friends who have only lasted a 2 laps at a time having gearbox issues/car rev limiting itself etc..

Not normal and we noticing a few of the same complaints coming from local South Africans, with the new facelift 2012 C63 models.
I'm quite sure it's a small problem, but one that needs urgent attention world-wide.

I had the same problem, M to S+, lose power in second gear, and had to upshift to 3rd in order to get the car move! Merc should seriously look in to it. I think it's MCT transmission problem!

It's just conservative programming, intended to prolong life of components. I don't think there's a "fix" other than adding coolers.
Even the gear oil in the manual box of my GT3 is water cooled. That car weighs 1000 lbs less and has way less hp/tq.
The C63 is not a track car.

As others have stated you may have to add coolers to fix this issue depending on the track and your driving style. I don't think it's so much a "problem" more than pushing a street car beyond it's limits.

Totally disagree with the answer "its not a track car, if you want one go buy one".
In the purest form of a "track car" sure it may not be one. But when you've got commercials of this thing racing around tracks, you sell it based upon it's time at the ring, you make it the safety car, etc etc....it should be able to not overheat & shut down at the track, you've got to be kidding me. It doesnt need to be the most amazing track car in the world, but it should make it through a track day, come on!!

Agree^^^^ but even the DTM safety car has mods up the wazoo. There are many members who have tracked their cars with success (albeit limited tracking time and limp mode occurring) and I think most of the track issues had to do with cooling which MB anticipated some mod for serious tracking...
Regardless, sad to say that so many cars are experiencing overheating so quickly...
I don't think the CLK63 ever had these issues because they were addressed for tracking specifically...

The track worthiness issue isn't unique to MB and the C63. Porsche's Cayman and Boxster (at least through MY2008) both suffer from high-g oil starvation and overheating power steering system at the track. Even the mighty C6 Z06 had oil starvation problems until the dry sump tank was enlarged in MY2009.

Had the same problem in China. Was only able to run the warm up lap and the car overheats and needs to be cool down. Outside temperature was about 27C, very high humidity, water temp stay at 94C, but oil temp peaks out at 143C. At 135C, the car will change from M back to S. At 143C, the car will limit engine rev to 4000RPM. The worst problem is on the highway, it will overheat and drop into safe mode if you try to take 5th gear from 4000RPM right to redline.
I did send the car back to the dealer to be check up. They kept the car for 2 weeks and returned it with the manufacturer confirming the car is fine.
Is this a design problem of the car? Or did I get a lemon?

I think I know why they bring in 10 C63 to the track every time for people to test drive and limit testing to 2 laps. These things just can take 2 laps (one warm up + one cool down) and they are done.
