Dear All, I drove a Y62 2010 model. Few months back while driving in 100-120 kmph with cruise control ON, suddenly the car had a jerking and immediately cruise control turned OFF. And first indication came on the display is of traction control. Within 2 mins all the other check lights turned ON and immediately car dropped the power and stopped in the middle of the road. I restarted the car and it started running normal. Again after 15-20 mins same issue came. there was a knocking from the differential side and gear was not moving from the 3rd. RPM was not going above 1500 i believe. This keep on coming and i consulted a garage and they were unsure about the season. Diagnosed and scanned the OBD, no faults came. Later another so called expert came, diagnosed and said the software is making the trouble and he suggested to reprogram it. I did it and it was ok for 5 months. Again i faced the same issue yesterday. Same trouble, same fault indications and same errors. I have noticed this is happening when the cruise control is ON. Don't know, maybe i am wrong. I have no idea what to do and what is the exact root cause of this. Anyone here facing the same issue? Any successful diagnosis done? what need to be checked and rectified? The so called expert technicians are lacking knowledge on identifying the exact root cause and exactly what need to be changed. Kindly advise on this.
