2016 freightliner issues

Making me nervous, I just ordered one to be delivered in August.

 

Have them check the bottom fan. It sounds like that isn't working properly which is causing it to overheat and throw those codes. I've gone through 2 of them on mine. It acts exactly like you described when it starts to go.

 

I was having the same issues as well and earlier this week while I was at the truck wash and them wash the apu engine and that has fixed my issues. The amount of dust in and on my apu was very very thick. I figure I'll every other month have it washed just to help it out. The place I went to didn't even charge me for the engine wash since it took less then 3 minutes, LOL.

 

If find that you are having APU issues and can get routed close to Shelbyville, TN so you can bobtail into the DC, do it. Quite a few of the drivers who used to run out of here will only have the guys here work on their APUs. I'd put them up against any other Prime shop. No joke.

That's not a bad idea at all. I wouldn't be surprised if the road gunk building up is what is taking out the fans.

 

With the location that apu is at in the truck, it's going to collect so much crap from the road despite that cover they have on it. I also recommend washing your truck engine every once and awhile as well. Helps you spot any leaks or problems during your pretrip.
