N20 Intermittent Smoke from exhaust


I have a 2014 328i with the N20 motor. My Car has been FBO Stage 2 (VRSF HD Intercooler, VRSF Catless down pipe, VRSF Charge Pipe, Ingen Intake, Custom exhaust) with a custom TuningTechFS tune for abut 8k miles.

Recently i noticed a small puff of white smoke from the exhaust when coming to a stop and idling after driving for 10-20mins. I took it to my shop they didn't find anything major, but said the turbo may be leaking a bit of oil into the exhaust and that i should consider replacing it down the road. The car drives normal, no codes ar anything like that. Its not constant, and ive only noticed it maybe 4-5 times over the last 3 weeks or so. Also had an oil change done about 3 weeks ago. All Fluids and oil is at the appropriate level

Wondering if anyone has had a similar issue?

On person on a FB group said they had a similar problem and one of the pistons ended up getting messed up and the car stopped running after a few weeks.

Thanks in advance for your responses
