@varin11 .. were you able to get the problem resolved ? I got the 3rd service done recently from HIM Patparganj and I find that the engine cover is vibrating and producing a strange grrrrr sound , which goes away as soon as you press it slightly with the hand. When I went back to TASS the service adviser there (i dont remember the name) said that "its like that only". But am sure it was not vibrating before . BTW does any one know if we can tighten it ourselves as a DIY ? because TASS dont agree its a problem at all !!! The cover is on 2 rubber "protrusions" . One side is pretty loose and vibrates. Please see the attached image(not my original image) . The (1) is loose. Is it normal ? Any idea how to tighten it. ??
