Alex1978 Posted 1 hour ago Share Posted 1 hour ago Hello, the entire cabin of my 2009 325d m sport vibrates from 1500 to 2000 rpm, and it also vibrates while idling. Someone said the engine mounts were the problem, but I don't see any obvious wear and tear on them. Is there something loose that could be causing the problem? Lots of vibration on the plastics under the hood makes it sound like it's coming from the engine's top. Works without a hitch, dropping power, or error messages Quote Link to comment Share on other sites More sharing options...

VWDaveBMW Posted 59 minutes ago Share Posted 59 minutes ago There shouldn't be any noticeable vibration at 2000 rpm, even if the engine mounts are damaged. They should be as silky smooth as the petrol 6s, but with a gruffer tone, so the engine must be running extremely rough. You can still learn a lot about its performance from a live diagnostic, even if the dashboard lights aren't on. If the EGR and manifold have not been decarbonised recently, it is worth doing so as it may improve the running of diesels that become rough due to soot buildup.

Screwdriver_1 Posted 57 minutes ago Share Posted 57 minutes ago Lower pulley chain. Take a look at it while the engine is running to verify its true run-ability. Quote Link to comment Share on other sites More sharing options...

Darrellll Posted 56 minutes ago Share Posted 56 minutes ago At low revs and idle, my engine sounded grumpy, almost like exhaust rumble. However, unlike the OP, I did not experience any vibrations in the cabin. I later installed the serpentine belt (the one I had ordered was too large), and it makes a world of difference in terms of noise reduction;took care of the crankshaft pulley and idler pulley/tensioner. Now I'm worried about something else—I can hear the turbo turning on and running down. Quote Link to comment Share on other sites More sharing options...
