Volvo S70 ProblemsMaster Window Switch Assembly May Fail
The master window switch may fail, allowing the windows to move in one direction and not the other.
The anti-lock brake system (ABS) Control Unit has a high failure rate. When this fault occurs, the ABS light will illuminate and codes may be stored indicating a problem with the ABS Pump Motor, or Wheel Speed Sensors, but the problem is the ABS Control Module.
Other symptoms may include an illuminated Check Engine and transmission shift light. and the speedometer may stop working as well.
Note: The brake system will operate normally however during a panic stop the Anti Lock Brakes will not work and the wheels may lock-up, causing a lack of vehicle control under these situations.
Many complaints have been reported regarding Volvo S70 transmission shifting issues. Long shift times between gear shifts, hard shifting, hard downshifting and a loss of transmission operation all together to name a few.
If the issue is minor, a transmission software update may fix this issue so if available, the software should be updated before any repairs are made.
There are several technical service bulletins (TSB's) available from Volvo that address these shifting issues and they should be consulted by the repair shop during the automatic transmission diagnostic process.
Regular servicing of the transmission fluid can help with preventing transmission failure, but not in all cases. Follow the suggested fluid replacement interval recommended by Volvo. You will find this in your owners manual, or find it here: http://bit.ly/Volvo_Owners_Manuals
