SPORT button & exhaust issue
I was wondering if you guys have the same issue...
When the sport button is engaged.. the exhaust valve sometimes still closes between 2k and 3k RPM, only to re-open above and below this... it's not always like this.. only about 70% of the time...
I thought SPORT buttton leaves the vale open at all times.
I thought there could be something wrong with the valve, but since there is one on each side... and since they both close and open at exactly the same time, I am ruling out a physical/mechanical issue with the valves themselves...
Did anyone that this issue and how did you resolve it?
