i just bought a 2013 335i and it has the same rattling noise. the car came with aftermarket intake pipe and ignition coils. the car has 96.6k on the odometer without any check engine lights. i got it off a small dealer. oil levels are good temp. levels ok as well got a 'reduction in brightness due to excess temperature' and a tune was also found in the car. also metal shavings in the oil.

upon starting the car a rattling noise is heard from the engine also when i accelerate. its loudest when I am idling on a red light. but im not getting any lights on the dash. any thoughts and advice would be greatly appreciated.

i tried to upload vidoes but no luck.
