My 2008 Mercedes E350 with 119K miles produced an OBD2 code P2006 and I found a broken plastic rod in the intake manifold actuator lever configuration. This is a common issue with the M272 engine in these vehicles.

To remedy the situation, I bought a new Pierburg manifold (OEM, same brand as the factory one I removed) kit from FCP Euro and installed it myself. I followed instructional Youtube installation videos step by step and took my time, no rush job or shortcuts. After the installation was complete, I thought the car was finally fixed.  However, after using my OBD2 scanner, I'm now getting a P2015 code and ME/Motor Electronics Module code 0524 ( Bank 1).  For the record, I have not had a check engine light, even when the old manifold was confirmed to be broken, the car still passed the state inspection and emissions test.

The car seems to run smooth but I feel it could / should be more powerful. Recently, I had my neighbor sit in drivers seat, start the car, then step on the gas pedal to rev the engine. However, I saw no movement of the intake manifold actuator arms or linkage. The lever / linkage is functional ( it's new & and snaps back when moved to the right ) and no hoses or wires are within the path of the linkage /arms allowing proper (free) unobstructive movement. To the best of my ability, I checked to make sure hoses had no dry rot, cracks and the hoses were routed correctly with secure connections. In addition, I performed a similar inspections of my wires, clips, connections and the odd things moved around during the initial disassembly and installation. Lastly, I looked online for a related fuse to check but could not find any information regarding one.

While I was able to install the manifold myself, I'm not mechanically inclined and a newbie to DIY repairs. Aside from watching hours of instructional repair videos (pre-installation) and the actual installation process itself, this project has absorbed countless hours of my time. On top of that, I have spent an additional 2+ months online researching my new codes/ Issue that arose after installation and fiddling under the hood in mostly below freezing temperatures. If I take the car to an actual mechanic at this juncture. I'm gonna feel like a complete failure. If anyone has any insight on the matter or a testing procedure or troubleshooting tricks that could lead me to isolate the true issue, I'd be very thankful.

The OBD2 scanner I use is an HT500 Bluetooth dongle, it sold at Walmart as part as their "house brand" Hypertough.  However, it is made and supported by Innova and uses the Repair Solutions 2 application.
