I currently have my car in the shop having a new exhaust/downpipes built with a tune coming next week; however, last night we noticed oil in the intercooler pipe from the turbo on the passenger side. It wasn't a ton and the car didn't smoke when running, but there is some oil in there suggesting that the turbo is possibly going out.

My question is:
Has anyone upgraded turbos on the M276, and if so, what is the limit that the transmission can reliably hold? This is the 7-speed tranny

Same issue here. The car isn't tuned. It's completely stock besides the air filters which are K&N and the headlights that are modified. Got oil in my passenger side turbo. Dealer isn't willing to even take a look at it. Not sure how to go about this. Got 20 miles left before warranty ends.
You can view my thread and some pictures of the turbo inlets here: https://mbworld.org/forums/c450-c43-...8-c43-amg.html

If turbo lag, this could be a possibility :

I believe 1,000 Nm is the limit at the torque converter, for other mechanicals I don't know......but one would use 75% of that to be safe.
