Hi,

Please can anyone help? We have an intermittent fault on our Cummins Diesel straight 6 350 2003. Engine model 1SB 300. It's coming up with and engine warning light and fault code 2383 with diagnostics. They have changed the ECM, Wiring harness and the Actuator motor and it's still making this intermittent fault and chuffing noise.

Please see the attached video.

It's been in the garage 5 weeks and the Cummins mechanics are at a loss. If anyone can help to solve this issue, we would be very grateful.

Thank you in advance.
