Diagnose Low/No Boost on a Turbo Volvo

IPD's CBVI started looking at my boost gauge when accelerting to see if was loosing boost and I deffinetly seem to be…

Let OFF the gas pedal suddenly at 4000-5000 RPM and listen for a “fluttering” noise of sorts – if you hear that, your CBV is definitely dead. IPD sells a good replacement.

  1. I own a 1995 volvo 850 (non-turbo fw-drive) and the light is on for ABS. Is there a way to find out what is wrong with it? I took it in
    for a diagnosis and they want almost $600. for the part alone and another $100 for labor. I am hoping to find
    someone here in Salt Lake City that is reputable, and will do a good job. Do you have any ideas?

  2. Mine did the same thing. There are a couple people on eBay that will repair them for 50.00. I did this and it works great. You have to have it removed and mail it off though. It is an easy job, and there are videos on YouTube.
