e92 Rattling :/

Johndong888 · 07-11-2012, 05:32 PM

Hey guys, wanted to post this here hoping for some opinions prior to taking it into the shop.

Lately I have been experiencing a sound that I can only hear during idle (It might be there while driving as well but I can't hear due to my exhaust)
The sound is almost like a "metallic" rattling that seems to be coming from the engine. It's almost like ticking at me.

It is very pronounce when I stand by the passenger door. It is also very audible when I am put my ears near the exhaust. Very stumped. Any advice or opinions will be greatly appreciated.

Info:
2008 e92 335i
Injen DCI
Vanguard Exhaust
Cobb Accessport
93 Shell Gas
New Sparkplugs installed beginning of May 2012 as well as Oil change.

THanks! John

wastegate?

Usual suspects for rattling are DISA, serpentine belt pulley bearings and wastegate. Since the noise comes from the exhaust, probably wastegate for you.
