Nissan Primaster L1H1, L2H2, L3H3 130dCi, 150dCi, 170dCi (2010-present, M9T 710, M9T 714, M9T 720)

Root cause
Oil starvation and carbon sludge buildup in the turbo oil feed line accelerate bearing wear, eventually causing shaft play, compressor wheel contact, and catastrophic boost loss.

Our recommendation
On a Nissan Primaster used for daily commercial runs, we recommend replacing the turbo immediately if shaft play exceeds 1mm or metallic grinding is audible. If oil dilution or crankcase damage is present, a full rebuilt M9T offers better fleet reliability than repeated turbo repairs.
