Hi Guys,
Thanks for your time and reply. Finally I managed to fix the issue.
I suspect the problem was due to recently I have upgraded my car with Multi-Function Steering Wheel (which wasn't there earlier) so I called the same guy and informed. As a result he asked me to come there, also I have remembered the guy who did the work replaced the Spiral and put another one (I am not sure why he has replaced that).
So, this time he has put another one (I have paid additional amount) which is better than the earlier one and now the problem is fixed.
Thanks
