Engine louder after throttle body cleaned

[Marleez]

Just had my throttle body cleaned as part of my full service. Just  noticed its idling louder. Will it go back to quiet?

That sounds odd. I wouldn't expect cleaning the throttle body or changing the oil to make any difference to the engine sound at idle. What kind of sound is it making and have you checked the dipstick since it was done? Are you sure they used the right oil?

It may be something to do with you having F-Sport. F-Sport has special port in intake which transfers some engine noise into the cabin... now assuming it was blocked somehow, maybe after cleaning you just hear more noise via that port which you have not notice before?

Maybe, I also had a major service which included new spark plugs and oil change 5w30. Not sure what else would cause this?

And it is only idle which is louder? Any particular noise?

I went back to the garage.

 All is ok. Got it checked out.

Maybe it was just me thinking it was abit louder.
