So I got my car back last Friday and did not get to drive the car until this week. So far so good as the error message has not come up. The repair bill states the following" No CEL on when driving into shop. Engine runs good. Read fault memory. FC:4952 SCR pressure control overpressure is stored with frequency of 2.

I hope ard can make sense of this.
I wonder how much does the boost pressure sensor cost and if one can expect this needing to be replaced every 50K kms.
Your thoughts please.
