Dusted means dust ingress past the little panel filter they run. The left turbo is the first to go. They have made improvements in later series but this thread is about buying a second hand one, so relevent. As is mentioning starter motors and alternators being stuffed wherever they fit rather than where they should be. As stated, most are ok but if buying a pre loved version I'd be looking hard at how it has been used and not assuming anything. Also talk to turbo specialists about sludging the turbos. Motsons recommend oil changes at no more than 3 months on that motor due to those issues. That in itself is expensive if you don't do big miles. They aren't a high compression diesel motor of the old school, and most people who buy a new gxl/Sahara would have zero cares about this stuff, they just get another one at the end of the lease. Not saying don't buy one, just saying at the price/age bracket this thread is about, the above points had better be on your radar or you could get bitten like my mate did.
