I’m still quite new to my T6. It’s my first Transporter.

I’m hearing so much about failing DMFs and I’d like to know what to listen for.

is it just the sort of rattling sound, as described here? (Not specific to the T6.)


Or is there more to it?
 
My old vehicle was a Ford diesel and it became difficult to start, it was diagnosed with a DMF issue …… no unusual noises were noticed by me
 
Just replaced mine and I’m getting DMF rattle occasionally still. Not loud but not sure if this is normal as mines always been bad before changing
