Shared experiences on rough idle on 997.2

I just want to share my experience on an issue that I have had on my car and that is now completely fixed.
I bought the car in April 2019 and since day one, the tacho indicated engine revs that varied about 500 revs when the car was stopped. No issues when the car was on an A road or the motorway. I brought the car back three types to the independant Porsche specialist I bought the car from. The independent Porsche specialist told me that this was 'normal' and that 997.2 do that. Fuel consumption was down to 15 MPG.
Don't take the garage's word for it, it is not normal and parts need to be replaced.
In my case, I took the car back to Porsche who replaced the throttle body and the car woks fine now. An additional bonus from the rear is that the car does an additional 10 MPG more than before.
Don't clean your throttle body but replace it as Porsche recommend.
