Yes the turbo is mounted upside down on my caddy! Top mount so to speak! No DBF mind! Its a 104bhp. Is there not a replacement. If I change to PD150, I would need different downpipe, intake is on the other side, boost out goes down over gearbox not down around by crank pulley,I am not sure if the BLS engine has the turbo mounted upside down compared to typical PD TDI engines though. I think I have seen this on a VW Caddy 105HP PD TDI....
only the 140hp BMM caddy had DPF and top mounted turbo IIRC!!
