What is a CAC?? I haven’t heard of tgat one. What engine is in it??
I had a 15 with a volvo d13 and it never d-rated but went through throttle position sensors quickly. Best day was the day I sold it.

Hello, i got volvo semi tractor, VNL 670, year 2017. Back in december gave it to mechanic because of engine derate issue. they changed fuel water separator and changed CAC pipe. within two months, engine light came up again, and engine derated, mechanic now suggesting to replace CAC. would need advice, whats going on with engine? is there any relation of CAC replacement with CAC pipe or its just normal wear tear? market is crazy and seems im paying mechanic $4-5 grnads every second month.
