Hi All,

Some interesting going on with my temp gauge/over heating issue on my 2004 Cayenne Turbo and was wondering if anyone else had this scenerio.

1. Temp guage at 180 most of the time....

2. Sometimes (30 - 50% of the time) lately the temp will go up slightly only when idyling or slow traffic.

3. It will tick up to 185 (maybe) and stop and then in a matter of seconds it will tick back and stop at 180 and stay.

4. It never goes above that 185 mark and always goes back and only happens during idle or slow stop and go traffic and when moving goes back to 180.

5. No water pump leaks that I can find and no codes from a scan.

Does not seem like a stuck themostat but maybe an intermitten fan??

Any ideas or anyone experiecne anything like this, i like to hear your opinions or thoughts. Just wondering maybe if waterpump is going or sensor somewhere??

Dude, totally normal.

I stressed about this so bad, even when everybody sed it was ok.

I finally took my 2004 cayenne S to the dealership and they sed its ok.

So, as far as I have found, its ok.

My 06 Turbo cooling is acting weird just today. At idle or slow speeds it's always on 180. On the highway it seems to warm to 190-200. Stop and it cools right down to 180. Today on rhe highway the check coolant came on and temps were 210 to maybe 215. Stopped, only took maybe 1/3 gallon to top off. Still seemed to run 210 or so the next 10 minutes to home. Idled and it dropped back to 180. Any thoughts on what's causing this?

Possibly air in the system.
