Hi all
I just replaced my high pressure fuel pump in my 2011 e90 n55 335i x drive, it recently went and stopped giving fuel injection and threw all sorts of codes got a remanufactured one off of FCP euro for like 600. Got it all back together and took it out for a drive and after warmed up and all I did a couple pulls and it simply didn't feel as hard as it did before (stage 2+ fbo, and xhp stage 3). Went back home and noticed I had a rattle coming from the turbo side of the engine, now before on start up, in particular cold starts I had a rattle but it ran fine and pulled great, rattle would go away once it warmed up, now it seems to be there even at temp. I also replaced coil packs and spark plugs (ngk 2 step colder). And through the process I have ZERO codes thrown right now.
Any insight on what's going on??
Could this be the infamous wastegate rattle and it's all going bad at the perfect time I replaced my hpfp, and THATS why my pulls aren't as hard? I'm really not sure.
Thanks guys.
