Help in identifying wastegate rattle....

[shlim8]

After reading about all the wastegate rattling on the 335i, I tested the 335i that I eventually bought, going to the dealer in the morning unannouced and tested the car.... no rattle...This morning, which is 4 days after collecting the car, I realized that upon startup from cold, my car does rattle for afew seconds then quieten down.The rattle is quite loud metal to metal sound, more like a heat shield rattling type of sound....I'm just wondering if it's the wastegate or something else ? Does the wastegate produce such a loud sound ? Or would it be more of a muted rattling ? Or does it mean wastegate going south big time ?? Any sure way of checking wastegate rattling ?

yup, that sounds like wastegate rattle...especially if it goes away after a few min.

depends on your luck, i have had the rattle from day 1, after 12k km, turbos still going strong

So the wastegate rattle is a loud one ?? Mine goes off within seconds.

I presume if the wastegate goes bad, I lose boost n power.... Hmmm, I presume the opal insurance should cover this, when it happens... part of engine right ? Better read fine print...

i think this wastegate rattle issue was discussed before in several other threads..but for further details, you can try asking sifu gripen (supergripen) since he had experience replacing the turbos due to the rattle..but now it's refurbishable at Obermaier's for maybe around rm2k..try do a search in this forum or google..lots of info on the commonness of wastegate rattle on the 335i especially during cold starts..

YES!!!!! OPAL must cover those. Mine just had the ABS light and ABS failure message popping up. Going to Pro-Auto ( OPAL Panel ) for check up this week. Hoping my fuel pump will KO soon so can change before warranty expires. : )
