Question about 2004 Audi A4
just bought an audi a3 2002 model and the temperature gauge is not working, any ideas on how to troubleshoot this ??
thanks in advance.
How do I locate the sensor on a 2003 A4 1.8L? I see a blue sensor on the right by the firewall, and a green sensor on the left nearer to the battery on the left. Is it possible that I already have a green sensor in my car?

Change the coolant temperature sensor. They're known problem areas on other Audi models, including my A4. The part runs about $20 from www.ecstuning.com and it's the problem probably 75% of the time. If that's not a fix, it could be a thermostat that is stuck open and causing the gauge to never read warm.

I'm having the same problem and when I put it on the diagnostics it said that the Temperature gauge on the cluster isn't reading it or something like that. The thermostat and sensor are functioning properly, if they weren't the fan wouldn't turn on. I'm having problems finding the gauge, part of the cluster.
