Not sure whether any one of you facing the problem I do in my Linea 1.3 MJD. While driving in 5th gear, when the speed touches around 50 kmph, I near a noise from engine compartment (the moment you press the accellerator, the sound is gone and there is no sound when the car is at 60 kmph speed). This problem is there since my car crossed around 8K kms. I serviced my car in RDC ekkattuthangal and they replaced around 8 bearings (under gear box) in the car and said that the sound won't be there. But I kept getting the same sound. Last week I raised a complaint in FIAT customer care and got a call from them and they asked me to bring the car again for test drive. After they checked the car, they told me that the problem is because the RPM is around 1000 when the car is in 5th gear and speed is 50 kmph. The sound will come in all fiat diesel cars because at 5th gear the diesel cars will maintain around 1000 RPM. But before accepting that, I wanted to check in another diesel car. I could see the same sound coming from that car as well, not only in 1 car but in another car as well. Really surprised. My friend drives Nissan Sunny diesel and he told me that at 50 kmph, his car maintains around 1250 RPM and he doesn't hear any sound. I am not sure how many of you heard the sound, if possible can some on check and confirm. Mine is Sep 2013 manufactured car and now it clocked around 22K kms.
