[Resolved]  Skoda India — engine noise after software update

Address:

Bangalore, Karnataka, 560068

I have a 2014 rapid elegance black edition. 3 months back software was updated based on the letter that i received from skoda. Engine noise has become very high and the car has become sluggish after that. I have informed this many times to the dealership and as per them if it runs 2k to 3k kms all will be fine.
Even after covering the said distance, my issue still remains same. I would not have purchased this car if this was so noisy and sluggish. So please give me a solution immediately.
