Mercedes eKlasse: Rough Idle and Low Turbo Pressure Issues
I'm experiencing a few issues with my Mercedes eKlasse. The car shakes while idling and runs a bit rough when the engine oil temperature is under 75c and the transmission oil temperature is under 50c, but only in D or R mode. It runs smoothly in P or N. I've also received a message indicating low turbo pressure in bank 1. The RPM drops from 700 to 550-500 when shifting to D or R, causing a rough idle. I've replaced the oil plunger one-way valve in the vacuum pump, the vacuum valve, the MaP sensor, and the turbo pressure sensor. I've also cleaned the throttle housing and installed new camshaft and crankshaft sensors. I'm planning to replace the spark plugs soon, but I'm not convinced that's the issue. Any suggestions on what could be causing these problems?

Check for any vacuum leaks in the intake system, as these can cause rough idling and performance issues. Pay special attention to hoses and connections that might be cracked or loose. A smoke test can be particularly effective in identifying leaks. Let me know if you find anything or if you have further questions!
