Hi All, As suggested I brought my car to a mechanic to check out the live data with a scanner. There was one code that he said caused all the other codes to come on: P0522 - "The Charge Movement Flap (Cylinder Bank 1) Has A Malfunction". That code was one of the original codes which came on over a month ago when the engine started stumbling before I changed the coil packs and spark plugs. He said I needed "Intake Manifold, flap shafts, vacuum actuator and linkage" from Mercedes and the repair would take about 3 hours. I called a local Mercedes Dealer and he quoted me the following parts approximately $1,000: Remanufactured Intake Manifold - Part #272-140-24-01-80Gasket - Part #272-141-23-80Gasket - Part #272-141-22-80Gasket - Part #272-141-09-80O Rings - Part #013-997-90-45-64Hose Injection - Part #117-997-09-82 Anyone else have a similar experience. I wanted to get feedback before I order the parts. Is it possible that I changed the coil packs and plugs for no reason when this was the underlying issue from the start? Lastly I was told it was ok to drive until I make the repair....thoughts? The car just will not pass New York inspection. Thanks,Bob K

You can watch cold start data and see what’s going on, and you see any errors in the system. Only way to save time, money, misery, and guesswork. That said, does it have secondary air injection? That adjusts air and stuff on cold start. --FT Sent from iFōn > On Jan 2, 2024, at 12:05 PM, Robert Koziak via Mercedes > <mercedes@okiebenz.com> wrote: > > Hi All, > I recently replaced all the spark plugs and coil packs on my daughter's >2011 Mercedes C300 4Matic w/110K.
