    I have a 2021 Kenworth T680 paccar. The red engine light came on and beeping started. Went to Kenworth. Hooked it up for testing. They said it was the turbo actuator. Bought new one. Put it on. Programmed it. Went on my haul and the red engine light and beeping started again. Kenworth said they had to reprogram it again. They did and now the amber engine light, red engine light and beeping are all on. Anyone have any advice. I'm frustrated...

    The best advice i can give you is to learn how your truck works. Because these dealers will just throw parts at it until your bank account is dried up and the problem wont ever be fixed..

    for starters what code is it throwing and what is ur symptoms? i dont think a bad turbo actuator would throw a red stop engine code but i could be wrong. Its most likely emissions related

    I assume they hooked it up to a Davie tool for diagnosis.
    I got a red light and derate a month ago,it was the water pump speed sensor.2021 MX 13.$279 for the part.
