thanks mate, now that I got the turbo out and looked at it its def. the bearings that have gone in it...and more than likely that would be due to exactly wot your talking about. ( 95k car, that I dont know the previous history on, and probably ,its never had the filter cleaned), Bit pissed that the tuner didnt tell me about this filter,when I had the car booked in for a B service and with the upgrade going on it at the same time. Seems obvious that after a tune I was going to give it a bit, so that info more than likey would have saved my turbo.Will be removing the screen before the recon goes in...
