I just brought my 335i into the dealership yesterday to have them look at my wastegate rattle and do the battery cable recall work. I have recently realized I don't have the same pull in second gear I used to have when I first drove my car so I am definitely experiencing turbo lag now but haven't seen the half power symbol yet so I guess I'll see what happens. I'm kinda pissed because I bought the car CPO in January and have already had to have the fuel injectors replaced 3 weeks after I purchased it and now this is happening.
I'm just glad I'm having my local dealership look at it and not the stealership I bought it from.
I still love my car though, just pissed the crooks I bought it from didn't find any of this.
