Hello everyone. I had 2,3 posts regarding engine knock sound when reving in neutral. Been to the dealership 7 times, no one can find whats the problem. No error codes. Nothing. I met a guy who also drives swift but 2019 with 120000km - engine works like butter. I noticed something interesting when i revved his car, his rpm's are goind down normal like it should, slow down at 1000 then slowly drop down to 750. On my car the rpm drops instantly ! It feels like my car wants to "die". My car has only 33000km !!!

This happens only when the car is warmed up !

Hi, Throttle body / EGR or idle control valves or thermostat issues maybe ? Sometimes giving the throttle body a good clean is all it needs ! ( I’m sure the garages would have done this in the last 7 times it’s been there?)Hope you get it sorted 👍
