N46b20 strange noise after long trip

miek13 · 02-20-2020, 02:14 PM

Hi guys,
Last week I had a problem with my e90. After 400 km trip engine? starts making strange noises. I recorded it cuz its hard to describe that. Link:

Anyone has a idea what is wrong with him? Next day noise was not so loud like after trip.

Hello I made computer diagnose myself and that is what I found.

I found also 2 old errors (20k km) ago: 29F4, 29DD.
Maybe on my previous video that was catalysator noise?

In my opinin something is wrong with 4 cylinder cuz values are little bit too high.
