Codes for 2 Issues Occured at Once

[Our03z4]

So tonight while parked and idling my 2008 z4 coupe 3.0si I had 3 codes pop up at the same time. P0597, P0172, and P0175 are the codes. Just a freak thing that the t-stat and maf go out at the same time or could it be something else? The car has 91k miles on it. I'm sure it's ready for both of those but want to make sure it doesn't need something more. It has had a slight rpm bounce at start up recently. Thanks for any help!

Bump.

Have you check for vacuum leaks on intake?

Thanks for the reply! Actually got everything fixed. Was the thermostat and it was the maf sensor. Replaced both of those plus the water pump, valve cover gasket, oil filter housing gasket, eccentric shaft sensor, and some other things while I was at it. Car runs good again.

Good to hear issues are resolved. Thanks for the updating thread for future reference.
