mbm8800: Thanks..Can I have the contact number for the BMW authorize workshop you went? My mech need to charge RM5k plus for this service. which he say need to service the gearbox...

I am doubt too, because I still can drive even it is on the stall speed.means the gear indicator light alert is still on...

Hi there,

Hey guys,...finally I got my problem resolved....is not the gear box problem...I changed a computer board located at the left side of the car(passenger seat side)...and it's blue color circuit board....which cost me RM1.6k(used parts)...

Don't got cheated to changed the gear box!....my car is now working for a month without any problem....Thanks God!...

after the transmission ecu change, does the engine ecu throw a fault code on the serial number mismatch?

usually the transmission, engine and dashboard ecu have the same serial which needs to match.
