The C230K loses a lot of spunk in 80-90 degree weather. It's a forced induction car. For me, it's like 2 different cars in the cool air vs in the heat.

I'm not understanding. If the car had some major issue, you'd know it. It would be throwing warnings.

I was activating the traction control for a LONG time on a 1-2 shift... typically I don't ever do that or if I do it's very short (with a eurocharged tune). Engine note sounded slightly different as well (but maybe that's just me being insane).

Does this fix get you more power?

you are lucky that you got all those items replaced, Mercedes Canada still fails to recognize that there is an issue with this item.

It takes time for your ECU to learn

If the S/C wasn't working then the car would be throwing codes. I'm not sure what is up, but feeling of the exhaust pipe is not proper diagnosis for anything.

If it is having serious drivability issues you better stop driving it before the engine is ruined on the chance you have the head problem or a timing chain that's about to jump a tooth.

Get underneath the car and bang on the muffler and cats with your hand....if you hear rattles then your cat or muffler came apart internally and could be blocking the exhaust.

Broken thermostat = cooling system doesn't start at the right temp Or doesn't start at all = the loss of performance.

Like I've said you already answered your own question.

My broken thermostat and P0128 at 100k miles didn't affect performance in any noticeable way, so I'm not sure. Definitely not night and day like he's describing. mleskovar might be on to something.

Just drove my car at the local streetracing spot and mine is faster than it was before the service. I can hit 80mph at the second bridge(the finish line) now were before it would be just past 75mph.
