OBDSTAR DC706 now will virgin Mercedes Benz FBS4 VGS4–0-NAG2 gearbox TCU on bench mode without drilling a hole. Here comes the latest user feedback on VGS4 TCU. "Just wanted to give you some feedback regarding a job on a Mercedes W205 that came in for a gearbox replacement. The gearbox is a VGS4–0-NAG2. I used the OBDSTAR DC706 (I renewed my subscription specifically for this job). I connected the old gearbox and was able to read it without any problems in bench mode. Then, I successfully virginized the new gearbox without any issues (3 minutes, depending on your connection). Next, I successfully transferred the immobilizer data and entered the VIN. The whole job took 10 minutes. The vehicle started and is working perfectly. I should mention that the entire process was done in bench mode with MP001."
