I've had my 12 JCW for about 4 days and I've been loving every moment of it. I've noticed a few times when I park, that the fan comes on. I'm still in the baby-it stage until I get past 1,000 miles so I am not pushing the car. This comes on for about a good 30 and stops. I'm going to guess this is normal. (Additional assistance in cooling everything down)

Now, comes the part that I am not so sure about. I can hear the humming of the aux pump circulating everything around at this point, but I can also hear pressure around the coolant reservoir. I've looked for leaks or things bubbling and I see nothing. Has anyone noticed the same thing? Would you considering this just normal for our cooling system?

Thanks!

 

I have had mine for 30 days now, it seems to do that all the time too. I have read that our cars and BMW's in general do that...

 

Thanks latexsalesman! Do you get condensation from underneath as well?
