This is not so noticeable when driving on flat roads but in uphills it is kind of annoying because the RPM varies by more than 500 rpm or so. It happens in both 4th and 5th gear.
However, when cruise control is activated this behavior is immediately absent.
It seems to be the same issue as discussed in this forum: https://forums.swedespeed.com/showth...RPM-fluctuates
Any idea for a new volvo owner? |
The first suggestion most will make is to change the oil. At that mileage the fluid will be so degraded.
