M140i/Orange 182
comming from the engine or maybe in the region of the exhaust manifold. Now this only happens when the car has been driven, up to temp and then driven again 2 hrs after.( when the engine is half warm but no temp on the gage) This only happens when idling, when reved the noise goes away.
one other theory is my cat is fecked? iam running a milltek system as well.
this is the best i could explain it, any help guys?
cheers.
