Star Diagnosis Code
I have a 2006 SL500, which I had a transmission problem with. The car wouldn't upshift. All I had was first or second, reverse and park. I was also getting an error message saying something about brake pressure.
When I plugged my OBD2 Code Reader into car I got the code P0798, which points to a pressure control solenoid not working correctly. After I had the car towed to the Mercedes dealer they replaced the transmission valve body ($2000) and the B3 Brake Control Solenoid.
So here's what I'm questioning. While the code my scanner got was P0798 the mercedes tech got the code P2112. I'm sure they got that code by using their Star Diagnosis System, but I don't understand why all the symptoms the car had were pointing to a different solenoid. And, the other thing I'm questioning is why they changed the valve body.
While I plan on talking to the service writer about this I thought I should come here and ask my questions before I talk to the service writer. Those questions are:
1) Why the different code?
2) Why was the valve body changed when there were no other codes?
So, if anyone has something they can add that's related to my question it would be greatly appreciated.
