Check the front turbo/air intake gasket! Remove the skid plate from the bottom of the car and look directly up at the front turbo. After 4 years there is a decent chance the O-Ring on the intake side of the turbo has gone stale and you will be leaking blow by oil out of the turbo. EZ fix to just replace the the O-Ring but a pain in the ass if you’re not comfortable with DIY and disassembling parts of the engine bay… easier to have the dealer do it.
