Hi , just adding to the thread as i've just found this forum and would like to share my experience about my Harmonic Pulley self-destructing .
My Pulley Number is A112 030 0000 which was a re-call in USA but Mercedes UK don't want to know one bit and say no problem it was just Mercedes cars sold to the USA that were affected ! Funny my Pulley is the same number and chassis number that falls into the re-call region...
Must be an American Built Mercedes .....
Added a picture to show the Damage & pulley number .
If anyone got a positive response from MBUK please post on this thread how you got on ... Thanks
