At the dealership getting a new EGR cooler
Yep, the little whistle and some white smoke ended up being the EGR cooler. I asked them specifically to closely check the headgaskets, but the diesel tech said they looked fine.
She's close to 90k miles, so I'm getting the trans flushed and the spin on filter changed.
My question is this, when I get it back home, should I drop the pan, change the internal filter and replace the fluid that I drained out?
Would that be overkill? The tech told me I don't need to change it when doing a complete flush at the dealership due to the way they pull the fluid out and do something or another.
I have the internal filter and I'm itching to change it, clean the pan, and check the magnet for some strange reason.
