Hi, what temp should my car normally run? It has been running about 60 C now that it's cooler. If it ides for a while it wil warm to about 80 on the panel gauge. That seems cool to me; my old 420 SEL runs about 80 C all the time.

 

new member here and also have a 2005 e320 cdi with 98k mi. I had the same prob. Changed the thermostat and its all good now.

 

I have a 320cdi W211 and the temp should always be around 90-92
