Coolant temp sensor
« on: January 17, 2020, 01:11:42 pm »
Hi, i'm going to change both coolant temp sensors on my DSG. I've read this guide

Do you really have to remove the alternator to get at the one on the drivers side?

Yeah the thermostat bolts don't seem to be accessible with the alternator in the way.   It's not that bad a job in practice, in spite of the horror stories. 

The thermostat issue is worse on MK7s, and needs doing more often, and costs a lot more money...... just to make you feel a bit better!
