Thanks for the suggestion. I agree that the ABS does not seem to be involved. I disconnected the wiring and I still have the problem. Does the OBD port on a Volvo require a special code reader or will any of them do? I think my next move is to find out what codes are logging.

Hi all, I'm new to Volvos as of 2 weeks ago. I only know what I have read on the web. I bought a 99 V70 FWD with 101,000 miles on it from a small lot in Chicagoland. Driving it home the speedo dropped out and came back. A day later it happened again with all kinds of dash light activity. Sifting tho...
