Title: temp gauge fault help/ideas ?
Post by: will gti on 01 December 2010, 10:19
 hi, my temp gauge only seems to be going half way to 90? i have done a search about the sensors etc.....just didnt wanna go replacing random bits, thought it best to ask you guys  on here first. Oh and btw its only been since we started getting cold weather and i DO have anti freeze in.  :undecided:

thanks

does it ever get to 90?

two main suspects are temp sender or the thermostat

you can use VAGCOM to log the temp sensor or identify a fault with that.  If that comes back all clear then its your thermostat
