Hey everyone

Bought a jazz blue 20th 1.8t and have an issue

Car wasn't heating up to 190, staying around 130-160

Swapped out coolant temperature sensor and the thermostat

Car won't go over 160 but have heat and all seems right

Not sure what to look or test now...

I would suspect that the gauge is off. Not typical for the motor to not reach temp.

Will it reach temp if you let it idle? Do the fans kick on?

Hmm are you sure you didn't put in a lower temp t stat? Try to determine at what temp the t stat opens by touching the lower hose and ur vagcom. Its opening too soon. Should open at 87°C for 1.8t (not sure). My vr6 opens at 80°C. I had a similar problem of the car never reaching op temp. Are you getting a dtc for coolant system malfunction? My problem was a thermostat that was stuck open.
