Mine are silent too a 200k kms. Frankly as a 2010 it is now old enough that if and when the time comes I will either just sell it to a motivated buyer who wants a mechanics special bargain or do it myself at a leisurely pace as a hobby in the garage. It's days of daily driver duty is quickly coming to an end and once the vehicle supply reaches normality it will be replaced on daily drive duty with something frankly more efficient.
thanks for your advice, but I am capable enough to make decision whether to keep this car or get a new one
BTW, I like NA and BOF
