Hi all i have a big problem in hand as owner just called the cops on me i brick his car!
Story
car came to me with dme dead DME 1
i copied out ISNa nd stored on pc, went o ebay and ordered DME,CAS4, KEY AND ZGW belonging to BMW F10, i put in the unit and car started with engine steaming well, i then drill a hole with a punch
using using ISN boot mode i wrote in ISN and car started after coding with engine shaking cylinder 1-4 not working properly, i then did valvetronic reset through launch V, still no luck i then used autohex to update both dme and coded them and car ran fine, drove car around for 3 days and updated other module around car, Tacho of KOMBI (speed clock ) was not working when driving car so i opted to flash KOMBI but was unsuccessful kombi bricked.
after kombi bricked car would no more start or start hard with message dme cannot communicate with kombi over flex ray bus, i tried all but no luck, i then bought ICOM with ISTA-p and ESYS, ISTA-p could not flash KOMBI also i then decided to use ESYS, read FA save it and activated read SVT got to expert and read I-STEP which was F10-12-11-503 did TAL calculation went back to TAL processing on comfort mode and flash 4 unit zgw,kombi,amp,hud 3d,hu_cic, after update kombi worked with car starting well but with engine reduce power cylinder 1234 no more working car in LIMP mode.
now if i try to program DME1 and DME 2 autohex flashes the 2 dme's with same part number 2dme is now on single address (12) instead of DME1 on diagnostic address 13 and DME2 on address 12,bootloader of dme same coding file CAF same software end with _30 same details is contained in 2 dme so 2 masters map file instead of 1 master 1 slave map file.
dme 1is not seeing camshaft exhaust bank 1, even when i swap dme and code and start
dme 's work on F10 m5 after programmed with autohex to M5, checked dme details after flash on donor car 2 ecu flashed with different softwares and shows dme 1 and dme 2.
DME have been tested to be ok
FA that autohex uses for programming is corrupted after flash with ESYS, how do i get the original FA back and restore ECU back, thanks everyone for contributing.
