The vibrations haven't gone away but what I have noticed is that it becomes considerably higher on specific roads. Diagnosis is pending for when I take the Jet for the second service when I am back in early August. Will try this as well as swapping tyres and rims from a TD car (of course after eliminating the possibility that it doesn't have the same issue existing). Due for when I take the Jet for second service. Well that's a happy ending! BTW, my Punto has never had this issue and it is now over 4 years and 70k kms old. Where did you get the balancing done in Delhi?
