Hi folks, ive got skoda superb 2007, with 2.0 tdi , 8 valave engine , engine code BSS. it is hard to start and have terrible sound out from engine. Very little power also. Trying diagnose the failure of components, before strip engine, any idea what it could be ? No oil warning, no faults on diagnostics. Attaching video. Maybe someone would give a hint what would be faulty.
