I have recently picked up a second hand Golf mk7 2.0 TDI (150) with DSG MY2014, and today noticed that when driving at 70 MPH in 6th the RPM was almost 2,200. However, in the past it's been just below 2,100. So I switched the Cruise Control off momentarily and re-engaged it again, and the car sped back to 70 MPH, but this time was just under 2,100 RPM as normal. Has anyone else noticed this?
