Car is Skoda superb mk2 2.0 tdi 170hp. So removed dpf and egr and also replaced my turbo with gtb2060v. The car has not been started for 3 months. I finished installing all the parts and started the car today for coolant bleeding and noticed the knocking sound coming from the dsg gearbox. I didn't do anything with the gearbox. I haven't warmed up the engine nor gearbox yet to see if the noise would go away.
