Hi Guys,

1. Error Codes P0521 P0063 Thrown on my 2006 C280 today, along with Pending Codes: P0024 & P2006.
   1. P0521 Powertrain/Engine Oil Pressure Sensor/Switch Range/Performance
   2. P0063 H02S Heater Control Circuit Low (Bank 2 Sensor 3)
   3. P0024 Powertrain/"B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)
   4. P2006 Powertrain/Intake Manf Runner Control Stuck Closed bank1 a)

Have a very good local Benz shop which I'll take it to shortly, but throwing this out to notify others AND to get feedback from those so inclined to provide it.

Cheers,
-Foggy

 

Since I received no feedback within the forum, I was able to reset the Codes and waited to see if they would return.

They returned the following week as:

1. Current Fault: P0024 Powertrain B Camshaft Position - Timing Over -Advanced or System Performance (Bank 2)
2. Pending Fault: P2006 Powertrain Intake Manf Runner Control Stuck Closed bank1 a)
3. P0063 - Powertrain HO2S Heater Control Circuit Low (Bank 2 Sensor 3)
4. P0521 - Powertrain Engine Oil Pressure Sensor/Switch Range/Performance

Today I had the Cam Solenoid (aka Camshaft Adjuster Magnet), Left Exhaust replaced to repair the Item 1 Current Fault and reset the Codes. Part was about $30, Labor $48.

I'm told the Pending Fault P2006 is a matter of Intake manifold removal and replacement of some plastic adjustment arms with metal adjustment arms.
Estimate to repair with parts is approximately $1400.00. Failure to repair could result in catastrophic engine failure (ex. destroyed items in valvetrain)
