Most Common Volvo S90 (SPA) Faults & Repair Costs
ERAD (Electric Rear Axle Drive) Failure on T8 Recharge
Like other SPA hybrid models, the rear electric motor can suffer coolant ingress past seals, damaging internal bearings and disabling pure EV propulsion.
Whine from rear axle in electric mode, "Propulsion System Service Required" message, Petrol engine runs continuously
- Drive in Pure mode at various speeds
- Check service history for ERAD coolant inspection campaigns
Front Suspension Lower Control Arm Bushing Wear
The heavy executive saloon chassis accelerates wear on front hydro-bushings, leading to knocks over urban speed bumps and front-end tramlining.
Clonking noise over sharp road imperfections, Vibration through steering under moderate braking, Uneven front tyre wear
- Inspect front lower arm rear bushes for perished rubber or fluid stains
- Check steering precision on a test drive
D4/D5 Diesel EGR Cooler Soot Blockage & Leakage
On high-mileage or town-driven D4 and D5 diesel models, the EGR cooler and valve can clog with soot or develop internal coolant leaks, triggering limp mode and coolant loss.
Check Engine Light with EGR flow codes, Gradual coolant level drop without external puddles, Sluggish acceleration
- Inspect coolant expansion tank level
- Check for soot accumulation around the EGR pipework
- Review service history for EGR recall campaigns
