I changed mine yesterday. It had an aftermarket one installed. Was a bit hard to do but still doable. Took me around 2 hrs but I was being very careful.
What people don’t realize is the air dryer when replace also replace the air control valve and screen for ahi located on frame rail between air dryer and the ahi dozer. This will knock out the ahi dozer in short time. Mine is original with 1,380,000 plus miles. Inexpensive part I replace when I change my air dyer filter. Semiannually
Hello, after remplacing my airdryer filter and assembly(Done byVolvo Dealer). I am having an issue when driving after the cut off it goes a few pounds down then up again ( pretty much I am hearing the cut off too often). When I put it on park truck running it just sound like a leak but it keeps blowing the air from the very bottom of the hairdryer assembly (where the air comes out when it does the cut off) So do you have any Idea what can be the issue? What is the air control valve? Is that the same as the the AHI air pressure regulator? Thank you.
I got an SPN 3556 FMI1. Description on my basic scan tool says, dosing injector 7. Got it cleaned but still can’t clean code after a regen. Dealer says to replace the hydrocarbon module. Thoughts?
I’m getting a code( spn 3490 fmi 1)aftertreatment purge air actuator I bought an after market part on eBay do you think this can be causing the truck to not complete a full regen
I just had a code on my 2015 d13 for ahi module. I was thinking after market do to the cost and that i only use this truck to pull a fifthwheel trailer camper. I bet i wont go 5000 miles this year. Waht did you get on that after market one again.
Thanks for the video, very helpful.
