Hi,

i have a 2010 c30 that i just bought recently. When i was driving it the check engine light lit up and i immediately brought to the mechanic for diagnosis. Upon checking, the mechanic said that it's "ECM 2008", but they have already reset it. After a few days, the engine light lit up again and the diagnostic machine flagged that its ECM 2008 Faulty throttle system. this happened over and over again.. Need help to figure out whats the real cause of the problem.

Thanks!
