Every time I start the car the gauges go crazy, they go till the very end and back again. Then they work properly. Any idea what could be causing this problem? Is there a troubleshooting part on the Repair Manual? Where can I find it? BTW its a 2005 tC Auto.

Any info highly appreciated.

 

It's normal. But you can turn it off if you really want to:

its suppossed to happen, its called a diagnostic sweep. Most of the expensive cars have this feature.

in the tC maybe its for show, maybe its not, who knows.

Its just a coveted lil sportscar-esque feature!

 

Thanks! Now I see it as a cool feature, I didn't saw it before so I thought something was wrong.. anyway, its done.

 

The tC's all do that, you can stop the sweep like the 2nd poster linked to but I've surprised some people with that and they think it's neat.

 

it's just a show thing in our cars.
