i am experiencing this anomaly since the knocking software update i.e. my car was driven 10000 km at that time...... and then checked with diff friends.... some frnds on Pakwheels also felt and shared with me the same...... I even discussed this with the Warranty guy of a dealership to whom i used to go..... he said " Sir! what you felt is also in Atlas's knowledge. You have felt the right thing".
But Yes as per your Car odo now.... I feel it to be a must to carry out
- Cat Con Cleaning
- Throttle body Cleaning.
- Fuel Filter replacement.
- Spark plugs replacement.
- Valve / tapet clearances check / adjust......
