Hi all,
I have a question for all you mechanically-in-tune people on here. I was driving my car pretty hard with no problems. As I start to ease down about 10 mins after I hear a small quick rattle come from the engine bay. It only happened for about a second and then stopped. It happened only once again about a minute later. Any idea what this could be? It hasn't happened any other time after driving hard until now. All help is greatly appreciated and I apologize if this has been answered elsewhere.

My 2013 MCS had a similar occasional rattle up front. Turned out to be the turbo heat shield needed to be tweaked and the rattle has never returned after eight months. Good luck. DeanLinAZ

 

I don't have a turbo heatshield but thanks for the reply

 

Can you list year and model, as well as mods? That would help to get more responses, I believe.

 

I know that my 2011 MCS R56 makes some clicking noises after shutdown, especially when hot. Sounds like a large relay clicking. There is also the aux water pump sound.

 

My apologies, I was in a rush. I own a 2007 MCS with no performance modifications as of right now, seeing as though I just bought her a month ago.
