Need Location of the Secondary Air Pump Relay on a 2009 C230 4MATIC
I purchased a replacement relay from the dealer for the Secondary Air Injection Pump on my 2009 C230 4MATIC 2.5L V6 272.911 Engine.
1) Is the relay located under the hood, in the cabin, or in the trunk?
2) Would you have a diagram showing which slot?
Thank you!
