I want to also share what I have learned in regards of loosing the pops and bangs from the exhaust on Sport+ mode.
It is all related to the 3 stages of DTC codes on that car. If you get a check engine light:
- First, the code is active. You'll have the check engine light, and probably other messages in orange in the cluster. No pops and bangs present, and you also might have a kind of "safe mode" where RPM and acceleration are limited. At this stage, it will be impossible to delete the DTC. At the first restart of the car, the limited acceleration/RPM should go away, but the not the DTC or check engine light (and orange messages). You'll need to drive the car for three complete drive cycles before the check engine light comes off and orange messages be gone. (I'm not sure exactly what is a drive cycle, but you need to drive for a certain period, engine temp need to reach the normal temperature, etc... - You can't just turn on and turn off the car - That won't count as a drive cycle.)
- Second, the DTC is still stored in the computer, but no check engine light or orange messages. Still, no pops and bangs. At this stage, the DTC can be cleared with a code reader that has that function.
- Third, the DTC is cleared (you have to clear it with a code reader/writer) from the car computer memory (maybe the dealer can still access it with an expensive reader). At this stage, the pops and bangs are back.
Just tried all of this for a second time right now. I really thought I lost my pops and bangs for good as it's been a month since my check engine light was off and still no pops and bangs. Just cleared the DTC with my reader and they are back.
Hope this will help someone in the future.
Note: Don't ask me why I had DTC (P0087)...but they were caused by me, not by random faults on the car.
