Default Green coolant temp sensor - failure possible after only 1 year?
I had this updated to the "new" green version last year and 6K miles ago. but I still got the following code pop up a couple of times at highway speed and moderate throttle. STFA it appears this used to be $5 part, now $20-25.

1 Fault Found:
17704 - Error in Mapped Cooling System (check Temp-Sensor and Thermostat)
P1296 - 35-00 - -
Readiness: 0000 0101

Default Where did you purchase it?
I got one from PureMS and it failed in a few months. I posted about it and someone else reported a similar experience...

I just replaced with the Myler unit. Got it for $14 from the local autoparts place.

Default is that right? maybe it's a bad batch? only thing I've noticed is that my coolant temp
reads a bit lower than normal but I attributed it to winter and short drives.

Then, temp sensor or thermostat is toast. Use your VAG to determine which.

Send it back. 1 year warranty, we'll replace it, just cover shipping.

The thermostat controls the coolant temperature. The coolant temprature sender only measures it.
