That sweet smell that you are getting is most likely coolant. Easy way to check if your cylinder 2 is going is compression check and cylinder leak down test. Thats where I would start. Does the vehicle smoke? If so what color smoke?

yEAH FOUND A SOULTION, sorry about caps, suicidal post about it. my MAF scaling is correct ... I hope, so it must be leaking from turbo to TB

Since its smelling sweet, its the leak from turbo to the throttle body.... going to have to bring it in for a warranty. DAMN IT !!!!!
