Default I searched....Coolant Temp Sensor...where is it?! 3.0

I saw the tech article for the 1.8t but looks different than the 3.0. Is it in the same place? If not where is it?

The instrument temp gauge is sporadic on the B6 3.0. VAG says it was Coolant Temp Sensor.

Default I thought theres coolant sensor down in the passenger front as well

maybe thats a tiptronic thing (1.8T) but i could have swore i just saw a diagram showing one located down since i was poking around to figure out what was leaking on that side (radiator fin sadly).

It's under the intake duct which wraps around and bolts to the throttle body

Default I pulled apart the intake ducting. moved wires around from back of cams

I seriously cannot see it. Has anyone here done it? PLus there is no coolant line until the engine block which I can see the flange from under the car but from uptop, unless I take the head's off, it looks near impossible to get to.

Default You'll probably be the first, here...

to tackle the job....

A PITA on the 1.8T as well, however my 1988 80, was the same way. ;O)

We look forward to your after-action posting.

Not too many folks here DIY their machines...leases &amp; warranties ya know ;o)
