The best part of my punto which I was sold for was no vibrations while at showroom. Almost cars except Punto had best NVH . Now it has got some vibrations while at idle. I have taken it to FASS couple of time and they had replaced the engine bushings and everything related to their knowledge but the vibration remains. This vibration wasn't there before second service when they had done some minor work with steering rack. This vibrations fades post 1000 revs in odo. it gets boomy at 800 rpm ,boomy and annoyingly fills my ear. I am bit apprehensive about the cause of it could be engine or gearbox related pertaining to some alignments? It is not alarmingly disturbing but there is this anomaly which is haunting me whenever I think about my ride. Now it seems like I have to live with it which is some what annoying for a perfection seeking guy like me.or should I take to some private workshop, as Fass has almost failed to resolve it given 3 or 4 attempts . Your valuable suggestions and advice please.
