Whistle sound w the jb4
Hi
I have an 2012 135 . I install the jb4 about 2 years ago w/no problems . Only good things . The last week the car began with the whistle sound associated with the rear crankshaft seal . I change the valve cover for a new OEM part and the problem persist . I put the jb4 in map 0 and the sound disappears . pun in map 3 or any other map , and the whistle sound return only when the car is about to stop in the red light . What could it be ? thanks Other mods Catless DP BMS intake BMS meth BMW performance exhaust Intercooler |
