2011 335d Blueish smoke on startup and revs
I've noticed the startups and warm revs consist of a blue hue to the smoke. When at idle it's generally free of smoke. From what I've read it seems like it could be between crank breather, turbo injectors or valve stem seals. Any input or places to look/start would be helpful

Tuned and deleted, no codes that I can remember but I can scan it later tonight to confirm. And I believe it's sitting at 163k
I haven't gotten the chance to drive it much or dive into the car all that well. PO wasn't super helpful about what was done to the car regarding what tune was on it and to what level it was deleted |

Have the same issue, slight blue smoke when starting, DPF OFF ~168k miles. So far I have eliminated the breather both new and old type - no difference. My next type is the glow plugs power supply positive wire, apparently it burns inside. The initial preheating procedure is to start when the car is opened or the key is inserted into socket. Should be doing this some time next month.
