D4 VEA EGR…. what we now know….

Will be interesting to see/hear how this goes for him 🤔

Will await an update from Rob before deciding if I should go down the Berryman B12 piston soak or DMSO route. Anyone know if others have tried either on the D4 engine? I see threads on the Berryman piston soak on the petrol engine but nothing from diesel engine owners
