SQ5 Tdi coolant temp
Hello world,
This is my very first post as I bought a 2015 SQ5 Tdi today. When I picked up the car it was warmed up. I then proceeded to drive home, about 2.5 hours drive, out of which the first 30 minutes were in a 80km/h limit area going up and down some mild hills.
At some point during these 30 min I noticed that the coolant temp was about 75 degrees, instead of 90...which seemed odd, but thought maybe the car wasn't really warmed up when i picked it up. I continued to watch the gauge for the next minutes and it went up to almost 90, then back down, then back up a few times. Finally upon going up a hill it reached 90 and stayed there for the remainder of the 80 limit portion of the trip. Once I reached the highway and sped up to 120km/h it stayed on 90 until I got home.
Did anyone have this happen before? My first thought would be faulty thermostat (or sender) but maybe it's normal?
Cheers!

Yes you need to get that checked out.My 3.0L Tdi ( sadly not your SQ5 Tdi ) and we call ourselves free ! does not exhibit any behaviour like yours.Only time it's non-linear is when it's -35C.But it's accurate under these conditions. it's just curious to see how diesel temps run under really cold conditions.
