Its more common that this happens to euro 4 dpf engines..... post a clip of the sound including startup..... dont use a semi synthetic 10w40 use a synthetic 5w40 that 40 is the same viscosity at warmed up engine ...but the synthetic baseoil is more resistant to coking your hot turbo bearings.... also the 5 before the w is quicker oilcirculation at startup

And what ẗhinner"grade did u use?
