1. Anyone know how difficult it is to change a thermostat and whats involved?
2. Anyone use the climate control Trick to see the actual coolant temps
(Works on the S4 Climate control with the same buttons.)
3. Could someone please tell me what temps their b5-S4 normally runs at and what oil temps. (Code 49C with the above procedure)
Why do I ask? I had my thermostat changed and on the way there temps were around 94-98 mark on motorway and normal driving.
afterwards temps were 100-105 on the same journey back.... the dash needle was above 90 as well and its was never off 90 before.
I have just had these symptoms happen with my TT and a new thermostat , luckily I had the old one , refitted it and all back to normal.
Now twice in a row on two different cars........I have a suspicion that the factory thermostat is better than a replacement oem one, maybe replacement thermostats are being incorrectly built with opening temps being higher!
