Mercedes CLS350 CGI Engine not starting

[Drjones404]

Hi everyone,

Recently my car sounded like it was sucking a lot of air with a rasping noise that seem to be coming from the inlet manifold a day later it wouldn't start. The garage I took it to said they don't know what it is.

Any ideas?

Thank you

The symptoms you describe, with a rasping noise from the inlet manifold and subsequent failure to start, could be caused by various issues, including air intake problems, fuel system issues, exhaust problems, or engine mechanical issues. A proper diagnosis by a qualified mechanic is essential to determine the exact cause.

Does it crank?
