No longer in warranty found lots of posts on numerous forums all with the identical smoke issue and would you believe it most started after a main dealer service. 2.7 and the new sdv6 don't do it just the 3.0tdv6. There was an early mod by LR to do with a modified turbo drain pipe. But didn't fix all of them no one seems to know what it is maybe summat to do with primary and secondary turbos however new turbo didn't cure all cases. WTF have LR main dealers been doing on service to cause this fault. Hence she ain't goi back there again
