Hello, recently changed to an 08 A5 3.0 TDI Quattro Sport manual , great looking car both inside and out but have a few unanswered questions after a few days of searching.

First is the ride quality, my A5 has the factory lowered suspension (20mm) but I've noticed the ride seems almost bouncy at times, any road imperfections get amplified in a big way + the rebound feels strange when going over bumps in the road. At times it is distracting and annoying like the drive is not sending power consistently and cutting in/out almost like transmission/differential backlash as it goes over imperfections, has anyone had a similar experience?

Second question is about coolant temp, I'm waiting for my VCDS cable to arrive and connected up my OBDLink scan tool to check for any pending codes. I noticed that the coolant temp seemed high, took it for a run and tracked the temp which sat mostly at 99 degrees when in 6th gear at 1700 rpm/70mph with an 8 degree outside temp. The temp went up to 104 degrees at times but hovered around 98-104 for most the journey (all while moving), do these 3.0 diesels run warmer coolant temps? normally they tend to be the other way generally around the 80 degree mark (the dashboard temp sat dead in the middle without moving at all times during the drive)

Any suggestions?
