I Have only had this 1993 240 for about 4 months, but it ran great the first 2-3 months. Then I had a safety check done at a Volvo shop. They pulled wheels and inspect brakes etc. And from then on, I have the intermittent problem of the ABS warning lamp coming on while driving, and the speedometer & odometer stop operating. It sometimes seems to happen after hitting a slight bump, then other times the lamp comes on, and shorlty there after (like seconds) the speedo and odometer stop. Sounds like a wire problem, but I'm wondering if something has been tampered with behind the whole instrument cluster.
