I got my 2005 w211 fixed early december and the day it left the shop the engine light was on. Went back and they says its a pressure sensor problem. Here's a pic. any experience with this.... thanks

If you trust the shop-------whats the issue----change out the sensor or get a second opinion!!

wondering if anyone knows what this is and its cheaper to DIY ?

Left one in the photo is cam shaft position sensor($66), center part is idle air control valve($32), right part is manifold pressure sensor ($40). If it happened just after shop visiting, it could be their mistakes. ... Or they maybe already fixed it. Check the error code again and check vacuum leaks.
