Potential problem on my A250, occasionally blue smoke from tail pipe.
hello,
after picking up the car from dealer at new, until now, about 2 months, only 1500km on the car, (2019 A250 4M) i have occasionally found my A250, emit blue smoke after stop at red light, or long Idle, ( Ambient temperature around 25 C / 77 F ) and after blue smoke for about 1-2 sec, it followed by a kind of rich smell white smoke, and after that everything go back to normal again. this is only happen when car is hot, not happen at cold start. my engine oil is at full, ( usually blue smoke means burning engine oil ) and i have tested with temp gun at my cold air intake, the section after the air filter box, before going to the turbo, under the hood, the outside of plastic pipe got 80-90C. (176-195 F ), is this too hot? i have found this section of air intake, actually just positioned above the turbo charger heat shield.
the blue smoke never come out when i at drive, kind of strange, anyone know why this happen?
any other owner experience this?
thanks in advance

Book it into a main dealer mate as any issues should be sorted under warranty I would have thought! Not a mechanic but pretty sure brand new modern cars shouldn't be emitting blue smoke unless its just burning off some sort of residual chemical from the manufacturing process (theory?)

i actually found my another car doing this as well, drive in some stop and go traffic, and park for only 5-10 min, and start the car when car is still hot, a blue smoke come out followed by some white smoke, and after 4-6 sec, it's clean again.
you can do this test on your A class, see if happen or not.
