Hoping you can help me out. I've noticed that on cold starts my SAI doesn't kick in. Normally I can hear the SAI and then it turns off after a minute or so after starting, but now I don't hear it at all.

I've also noticed that when I turn the car on again (after driving and engine is warm), the temperature gauge resets back to 0. It then takes about 5 minutes to go back to normal running temperature (1/2 on gauge).

Could the above be a fault with the temperature sensor or is there an issue with the thermostat?

I don't want to have to go to the VW dealer and then have them rip me off if it is just as simple as changing the temp. sensor.

Thanks
