Diesel running 1-2 seconds after turning key off + exhaust sounding louder

Did you get this sorted?

The systems are consistent With the egr mod.

Mine is doing similar things Running I’m after shutdown. It’s EGR related.

Have you checked what codes if any are thrown at the moment

Yep, this is sorted. I dont know how or why, but fixing the exhaust pipe after center muffler fixed the shutdown problem. Pipe was completely detached from muffler.

No codes before nor after.

I anyway checked how is my inlet butterfly operating:

Engine off: shaft from actuator at rest position, meaning fully out or extracted (dont know correct word)

Engine idling: shaft from actuator fully in, touching the adjusting/stopper screw

Partial load: same as idling

Full throttle: actuator shaft moving fully in and fully out repetely, I think this is something to do with the rpm limiter

Full throttle and immediately back to idle: actuator shaft goes fully in when full throttle, then fully out when accelerator pedal is released and then randomly in and out for a second and then same as when idling above

I think no problems there? If you understand what Im trying to tell :P
