Hi all,
I just got home from Status today, Trent (who is a champ once again!) couldn't determine if I've blown a turbo wheel or not cos I don't have a cataylic converter to catch the shredding metal though.
Last night, I popped in, Trent went through the cramped engine bay, disconnecting one wastegate and see if it's over boosting or not. Rear turbo did but front didn't.
Trent listened to whole engine bay, plugged consult port to read AFM voltage, it appears all is dandy except for a whining sound from the turbos.
In conculson, Trent thinks front turbo may be broken, so I won't be driving this money pit for a while until I source replacment turbo (hopefully 34 N1), so will be buying new gaskets, studs and 100,000km service kit at same as turbo replacment.
Lastly, I'd like to say thanks to all whoever helped me in this thread, also many thanks to Trent @ Status for squeezing me in on his busy schedule.
Now, I'm going to put my wallet on diet!
Cheers
Grant
