B7, coolant idiot light came on a week or so ago. Dropped at Audi for 85k service today, now they want to keep overnight to check it out (advisor mentioned a check valve, dunno if he meant the thermostat or not, is there a check valve somewhere, and if so where, and what does it do?). Fault info below.
Single fault and car is running fine, temperature dial on dash didn't budge when fault occurred, just over middle mark where it always is at operating temperature. Freeze frame says 72C, which I guess is a little low (particularly for driving at 92mph, though it was cold out, -4C is 25F).
Is the freeze frame temp the same sensor that the dash indicator uses? I am thinking just a glitch. Anybody disagree? Anyone know what the "fault status" value means?
