RPM doesn't change much at idle. Its always at 610-620 at idle.
But car does rev higher to shift to next gear.

Makes me think it may have to do the electronics in climate control.
What happens when you try to change the temperature?

As soon as i turn on AC (Or Heater), the whole issue starts.
Just tried today, changing temperature doesn't affect anything.

It might be a silly reprogram or something. It's possible with these late model cars....
In my Integra, i have to shut off the A/C when i'm going uphill lmao. The other time when 2nd Narrows was shut down and i detoured thru Downtown for 2 hours in the blazing heat w/ A/C on, i lost at least a quarter tank of fuel... normal for old cars

I have checked with Mercedes, nothing new or update for AC since 2015.
I might change different tune. See if anything changes.

That combined which energy loss from running a/c compressor you get quite of bit of energy loss. Seems normal to me.

Thats exactly car shop tech told me.
I totally understand it. and agree to it.
But, I didn't feel this much of power lost or engine running rough 18 months ago.
