Issues Keeping it in Sport Mode?
For some reason I've been keeping my SL in sport mode lately, even when puttering around town. It just makes for a livelier, peppier drive. Not sure why I've started doing this now after owning the car for several years. My question is, how much, if any, extra stress does it put on the car/engine? Anyone else do this? I'm not talking about peeling out at every stoplight, just every day driving with a bit more zip. Hope this doesn't sound like a silly question...I have a 2013 with 28,000 miles.

I've always considered Sport and Agility/Sport+ modes to actually be easier on the engine and transmission since there is less low-speed load on the engine. Kinda like riding a bicycle up hill in 1st gear versus 24th gear. The engine gets to operating temperature quicker in Sport mode than Economy/Comfort mode, another good thing for the engine. Low-speed Pre-ignition (LSPI) is also more likely at low speeds in taller gears as the engine may tend to lug a bit. You'll never feel it because knock sensors will try to prevent knocking, but operating at a higher engine speed will avoid the risk.

The only time I use comfort mode is when I'm in traffic, evidently AMG P30 cars is not happy until sport or sport + is activated the pedal response is much more aggressive. It won't hurt the engine It's made to run strong; my MB mechanic all way says take the car out on an open highway at least once a month and air the engine out to keep her heathy, do not let the car sit in the garage for a long period of time.

At 75-80 mph, toggle from Sport to Comfort and observe if the engine speed is reduced.

I've been driving my SL550 2019 for about 5 years (leased it new and then bought it after the lease). Mostly in the Sport+ mode. While I don't have to commute, I drive it almost every day and as I live up in the mountains, 2 miles up and down on the steep winding mountain road. I usually use the 2nd gear driving down hill. Do you see any issues using Sport+ on that type of the road? And how exactly did you code the Sport mode by default? I have to switch to it every time
