Hey guys, new here and did some searching, and I couldn't find an answer to my problem. I have an 09 r56 JCW bone stock, no tune, no aftermarket parts. I was driving one day and my diverter valve sounded like a dove between shifts and the car went into limp mode no turbo spool threw a diverter valve code (I will post later when I have my scan tool I don't remember it.) I did some reading and found the diverter valves get fragile so I replaced it hoping the code would go away. It didn't. So I hooked up my scan tool and watched a few parameters, and noticed my boost pressures looked a little high. I took it to Mini paid $145 for the guy to tell me everything is working like it should it is getting too much boost and he's never seen an overboost issue. So no resolve. It only happens when the engine is at operating temp. The longer I drive the easier it is to make it happen and I can't have fun driving in limp mode. Sorry for the long post but I wanted to make it clear.
