All 3 Known Issues
The 3.0L inline-6 T6 engine (B6304T2/T4) in the S80 uses a BorgWarner BV50 twin-scroll turbocharger that develops oil leaks and bearing failure, typically after 80,000-120,000 miles. The turbo oil feed line develops cracks and the banjo bolt copper washers harden, restricting oil flow to the turbo bearing. The turbo also suffers from oil coking due to high underhood temperatures. The S80 T6 shares this engine with the XC60, XC70, and XC90 of the same era. The turbo failure often coincides with PCV system degradation, which creates a cascading failure pattern.
Common Symptoms
- Blue smoke from exhaust on acceleration
- Oil consumption increasing progressively
- Turbo whine or grinding noise
- Burning oil smell from engine bay
- Loss of power and boost
- Check engine light with turbo-related codes
How to Fix
Replace turbocharger (BorgWarner BV50, Volvo part 36012488). Replace oil feed line and return line with new units. Replace banjo bolt copper crush washers. Address PCV system simultaneously (part 31338685 oil trap). Clean or replace intercooler to remove oil residue. Use quality 5W-30 synthetic oil and change every 5,000-7,500 miles. Let engine idle before shutdown after highway driving.

The Aisin TF-80SC 6-speed automatic transmission in the S80 develops valve body issues and torque converter shudder, particularly between 60,000-100,000 miles. The valve body solenoids lose calibration, causing harsh shifts and delayed engagement. The torque converter lockup clutch shudders at 30-50 mph under light throttle. The transmission fluid breaks down over time (despite Volvo's 'lifetime fill' claim), accelerating internal wear. This same transmission is used across many Volvo models (S60, V70, XC60, XC70, XC90) and has a well-documented failure pattern.
Common Symptoms
- Shudder at 30-50 mph under light throttle
- Harsh 1-2 and 2-3 upshifts
- Delayed engagement into Drive or Reverse
- Transmission warning light or flashing gear indicator
- Stuck in 3rd gear (limp mode)
- Clunk on deceleration when torque converter unlocks
How to Fix
Perform transmission fluid drain and refill with Volvo-approved JWS 3309 ATF (3x drain-fill-drive cycles for maximum fluid exchange). If shudder persists, replace torque converter ($1,500-2,500 installed). For valve body issues, replace solenoids and separator plate ($800-1,200). In severe cases, complete transmission replacement or rebuild is needed. Preventive maintenance: change transmission fluid every 40,000-50,000 miles. Never use non-approved ATF - it will cause shifting problems.

The electronic parking brake (EPB) system on the S80 is prone to motor and control module failures. The EPB uses electric motors on the rear brake calipers to engage and release the parking brake. The motors can fail from water intrusion and corrosion, especially in northern climates with road salt. The EPB control module can also fail, leaving the parking brake either stuck engaged (vehicle won't move) or unable to engage (vehicle rolls freely). The system requires VIDA diagnostic software for service and calibration, making DIY brake jobs more complicated. Volvo recalled some S80 models for EPB-related issues.
Common Symptoms
- Parking brake warning light on dashboard
- Parking brake fails to engage or release
- Vehicle rolls when parked on inclines
- Grinding noise from rear brakes when EPB activates
- EPB stuck in engaged position - vehicle won't move
- Service required message for parking brake system
How to Fix
Diagnose with VIDA to determine if the motor or module has failed. Replace EPB motor on affected caliper (Volvo part 31262415 left, 31262416 right). If the control module has failed, replace EPB module (Volvo part 31329245). The EPB system must be calibrated with VIDA after any component replacement. For stuck-engaged EPB, the emergency manual release cable is located in the rear cargo area. Check for water intrusion in the caliper motor connections and apply dielectric grease to prevent future corrosion.
