Question for the experts
have been bringing my new to me cayenne 957 3.6v6 up to date with servicing bits.
have a temp issue in that when driving under load or uphill the temp on gauge goes from halfway to three quarters (80C to 100C)
I changed coolant and temp sensor at bottom left of rad plus thermostat and still the same , I did have a leak but that’s now sorted and vac bleed .

I plugged in the maxicom Mk 808 and it’s showing 110C water temp and 105C oil temp when at 100C on the gauge , I presume from this I’m fine and gauge is out.

what’s the acceptable range for the water temp ?? And both fans come on at @30% duty

when I pull in the big fast fans off and the hose it’s in is cold(bottom left of rad) , if I plug out sensor fast fan comes on full speed ???

Tks in advance
