Hi, this is my first post in the forum.

My name is Sebastian and I am from Colombia, I have a Lancer 2.0 Gas 2011 CVT, has approximately 103,000 km. Annex the image of the motor data (4B11). From 90-100 thousand km I started to hear a noise in the cabin when the car is running, it is exactly at 1500rpm, before or after these rpm the car sounds normal. I use regular gasoline (87 octane in Colombia), but I've also used premium gasoline (92 octane in Colombia) and the noise persists.

The car has done all jobs in the authorized dealer with original parts, In the 100,000 km service they changed:

Air filter
Oil and Filter
Spark-Plugs
The CVT fluid
Bushings
Coolant
Fuel filter

After all this noise persists. The car performs well, has not lost strength and overall I feel fine except for the noise.

Here's the video with the sound at 1500 rpm. (Listen loud)

Sorry for my English

 

Couldn't hear it from the video. What noise is it making? Whining, groaning, squeaking, etc.

 

Hmmm
