Dude, I'm going with a question, is there anyone here who does BMW? I'm solving a problem with a 535d 200kw, it says error 4530 that it doesn't work, if I give 1/2 gas from lower revs around 2000, it cuts off and adds swinging, and sometimes when I kickdown it goes normally, vacuum is ok, I haven't found a leak in the sled anywhere , all solenoids are new, the DPF is gone and off and the EGR is also flush and there is a Stage 2 400hp 800nm. It's been about a week since it started doing this.
