The code P0014 is for Camshaft Positon Sensor Actuator Bank 1. The possible causes are incorrect camshaft timing, wiring problems (harness/wiring) in intake timing control valve solenoid system; continuous oil flows to VCT piston chamber or failed timing valve control solenoid(stuck open). The code P0015 is for Camshaft Position -Timing Over-******** (Bank 1). Your problem will probably be that the timing will be slightly out, due to wear (stretch) of the timing chain; this will all be linked to the overall cold start issue and the timing position. Get that timing checked, or push for the full fix for the cold start timing issue.
P0015: Camshaft Position, Act B - bank 1, timing over
P0014: Camshaft Position, Act B - bank 1, timing over advanced Check oil level and quality. Remove n clean exhaust camshaft vanost actuator. Do not refit to exhaust cam, but swap with inlet actuator. clear codes...if eml on again see if fault moved to inlet cam. If so replace the actuator.
States B camshaft over ********, Bank 1. I can tell you some general things about this condition.
Each manufacturer has its' method of optimizing timing performance. The camshafts no longer are fixed in a single position in relationship to the crankshaft.
Just as some makers used to use chains or gears to time the camshafts, the makers advanced to mechanical or electrical-mechanical attachments to adjust the cams' position.
In some designs, an electric signal adjusts the position. In other designs it is strictly mechanical and automatic.
I am unfamiliar with your specific motor. On a Mercedes the part you need to replace may be externally serviceable with a plug-in part or may require removing the camshaft through the top portion of the engine.
The part you need may be called a Camshaft Actuator, Camshaft positioner or other term.
I hope my solution is helpful, and a parts search may give you a better idea of the shape and location of this part. Please rate my solution.
Faulty code. P0015, Cameshaft sensor bank. There are 2sensors in bank 1 and bank 2 totally 4. you should scan and get more specific result about exactly which sensor is faulty. After you shoudl replace it.
