my ABS control module warning light came on while driving during a road trip. no other malfunctions were noticeable. no power failure. no other warning lights. and eventually the ABS light went out. I called volvo dealer and scheduled service to come in and have the car checked out. I was told the ABS control module needed to be replaced. I authorized the repairs since my car was still under an extended car warranty. three days later the light came on again so I returned to the dealer. by the time I got to the dealer the light had gone out. the dealer called to inform me that the unit was working properly. I took the car on a road trip, the light came on again, so on my return from my trip I immediately went to the dealer. now 3 weeks later they have called me to tell me that the ABS pump was faulty and that they have replaced it at no charge to me. after I pick my car up and see the result I will report back here.

All incidents in year 2011, car is 6 years old with 32,000 miles.
Incident #1 - ABS failure message appeared upon starting car. I drove it around the block, power was noticably supressed like it was in a low gear or the brake was on. Parked, took another car to airport. Came back week later and problem was gone.
Incident #2 - Month later, ABS failure message appeared while driving. Ignored for a mile or so. Brake system failure message appeared. Electrical system failure message appeared. Pulled over. Followed instructions in manual to turn off car, let sit for few minutes, turn on again. Did not clear out problem. The car started fine, but then shut itself off by the count of 3. Towed to dealer. Replaced software for $300. Drove home 7 days later. Worked for a month.
Incident #3 - ABS system failure message came on as I started the car when leaving the mall. Car immediately shut itself down. Waited a few minutes, and it started and stayed running, but power was supressed, all readings (speed, odometer, temp, etc.) were flat lined at 0. Barely made it home, then it wouldn't drive (start, then shut itself down). Towed to new auto mech shop. Replaced BCM (Brake Control Module) for $2000. Drove for 1 month.
Incident #4 - Started car in driveway and it shut itself down by count of three. ABS message appearing again. Tried several times throughout day with same result. Added gas. No help. Towed to mechanic again today. No verdict yet. March 2011
