Went to the dealer with SIB 12-09-12 in hand for low speed intermittent loss of power. I have the PPK installed with previous integration version E89X-12-03-502. Left the dealer with a 1in long scratch on the door and a gutless E90. They upgraded the software to E89X-13-03-504. Final report shows ISTA/P version 49.4. The car seems to have lost a bit of power. Does anyone have any insite as to what this software version has done to the DME? I have an appointment at the dealer again to have the car door resprayed at an indepentant bodyshop. What can I mention to them about the car's lack of performance? Is it possible that the PPK did not make it back in the DME?
