I have one big problem with BMW X5 V8 4.8i ecu, the car no start. Starter relay and fuel pump relay turn on-turn off-turn on-turn off-turn on-turn off (intermittence synchronize between two relays).Battery is Ok. Ground connections from engine is OK. Strange it fails. Scan tool not recognize.
ECU flashing tool I use:
Galletto 4 V54 I can read flash and micro with Galletto with BDM mode.
Pin out for this BoschECU…
looking from the left: as the above pictures…
pin_7 and 8 +12v
Read points with BDM system. (Read with Galleto 4 v54) For security verify correctly ground pin position.
