the radiator was replaced, i said that in the original post

everything is OEM, i mentioned that in the original post

but where is the VAG going to get it's temperature data from? likely the same sensor. why would it be a different sensor?

chrismurphy

but given that this thing was replace three times,what is the likelihood it was connected wrong three times?

this isn't a case where the coolant temp gauge is wrong, the oil temp gauge is the same gauge as when i bought the car and it indicated a temp of 250F when the coolant light came on three months ago.

(yet today going uphill, slow, low gear, high RPM, climbing a mountain pass, the oil temp gets to about 245 and yet the coolant gauge didn't budge from "noon" at all - this problem is really effin annoying)

It's intermittant for me, so it sounds either electrical (like maybe a bogus reading at least some of the time) or that there is some constriction of coolant somewhere and it really is overheating. is it possible to get so much corrosion in the block that we get blockage somewhere? Maybe there's a hose or something that carries coolant that is blocked with stuff.

i mean i find it insane that a car with only 60k miles has as seriously a corroded radiator as i had when Audi says the coolant is permanent and the system never needs to be flushed.

this is bs
