The timing chain and exhaust variator were changed on my 318ci coupe and when I received it back the whole tone of the engine had changed . The noise could best be described as a more deeper and growling noise than before.

What can I do to remedy the excessive and unusual engine noise so that my car can perform normally again?

Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you

if the vehicle is performing normally and two techs have said nothing is wrong, it is hard for me to conclude from here what the issue might be or if there is even an issue.

if there is one, it would be due to a software issue or the installation of the new variator.

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
