Hi folks. My son's 320d Compact's turbo has just died in central France. I'm going out this week to change it and wondered if anyone could tell me if there is anything else I definitely should change while I'm at it. Dealer gave me part number for the turbo, and added 11127799224,filter, which when I looked it up seems to be a crankcase breather, and 1142247302, line, which I think is a pipe. Do I need these, or can I simply clean the breather assembly? Also are there any specific tools I should have with me apart from a socket set and torx set?
