2001 Xc70

MVS Volvo Forums member jcb went to great lengths to isolate the ECU in his 2001 XC70. He did work to make sure it was the culprit. This forum topic is how he diagnosed a failing ECM/ECU on his P2 Volvo. After two days of troubleshooting, I’m ready to send my ECM out for repair (2001 […]

Fast Friday Volvo Performance and Tuning

Two weeks ago today we started working with RZ Design on the R32 turbo kit they offer for 2004-2007 R models.
