Help. After replacement of the alternator, I started getting the dreaded Restricted Performance warning. No fault codes showing up on my cheap Bluetooth adapter. At the time of replacement, mechanic suggested getting battery replaced. Thinking that would be the sensible thing to do on the basis that these cars are a bit suspectible to electronics, I replaced battery. Still getting the dreaded RP though. Would the battery monitoring system cause this? 2009 XF 3.0D Any help appreciated.
