Just bought the car and drove approximately 30 miles and the tire pressure monitoring system light came on. Drove another 10 miles home and arranged for an appointment with the dealer for correction/repair. Noticed that the error warning did not come on initially after vehicle was parked but, seemed if I drove about 25 miles or more the light would come on and stay on, and this is what occurred until I went to have it serviced. Dealer get me for 4 hours and told me they could not get the tires to read. The dealer then made an appointment with Volvo for correction/service, and they kept me for 3 hours and said they checked the tires and reset the sensors, and believed it was the battery because the voltage was not high enough. So they were trying to get the battery to fail...this did not even makes sense. Anyway they said, they cleared the code and drove it and it was fine. I left and got about 20 miles away and the light came on again. The third time I took my car back to where I purchased the car (not Volvo) who took it to another Volvo dealer and it one week to tell me, the tire pressure indicated on the door panel which is 35psi is incorrect and it really should 38psi and the codes were cleared and they drove it and all was corrected. I left and drove about 25 miles and the TPMS error light was on again. Needless to say they cannot detect what was wrong.
