Volvo S70 Problem Report
Volvo S70 Check Engine Light Due to Failed Secondary Air Pump
This is an easy fix. Check valve fails, condesation enters pump, bearings freeze, shazam CEL light is on. Air pump is under battery tray. Buy a rebuilt pump with warrenty on ebay ~$150. Buy a new check valve ~$50. Buy a new relay (#2 in main fuse box) ~$20. Replace parts. Done. - Visitor
