BMW 335d 2014 hissing/whistling sound
My 335d is making a weird hissing/whistling sound from the back of the engine what can that be??
When I drive the car for a good few miles the sound will quite down but on a cold start it’s really loud. Also when I give it some the cabin smells of burning oil coming from the air vents, And alittle bit of smoke coming from the kidney grill. Has anybody experienced this before?? I’ve checked the oil level and it’s perfectly normal |
