Boost pressure sensor signal interruption oKurzschluss to earth Code: 003F01. That is my only code. It comes back after a couple of days after I clear it.

It's an 09 X5 35d w/ 44k miles. I replaced the MAP sensor last month. It hesitates while accelerating gently. In addition to the sensor I have changed all vacuum hose, actuators, and the red boost hose. I pulled the manifold last week and there was not a ton of CBU. Any ideas what I should check next? Could Rheingold help?

The sensor wires directly to the ECMs so I don't think there is a ground connection point to check. I suppose there is a chance the new sensor is also bad. That is a easy $70 check. I checked ground with my volt meter and it shows as good even when I wiggle the pigtail of wire around. Thanks
