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.

 

Dealing with engine issues can be quite a puzzle, especially when you're facing recurring problems. It's frustrating to keep investing time and money into repairs. While I'm not a mechanic, it does seem like there might be a connection between the CAC pipe replacement and the subsequent need for CAC replacement.
