2012 Bmw f20 Automatic issue please help

HI guys,

Just wanting to see if anyone else has had issues with the 8sp auto. I noticed the other week that there was a slight jerk between shift 1 to 2nd gear.. after driving for a bit it kept on happening and even slowing down in the gears, it happen from 2nd to 1st. Then the drivetrain warning came up and put the car into limp mode.

Obviously i took the car to a mechanic and they cleared the errors and cleaned the plug and works fine. week later happen again, mechanic did the same thing only this time it was a transmission mechanic. Now his saying i could need an possible rebuild but will need to look into it more by actually removing the gearbox.

The bmw is a 2012 model 118i sportline and only has 72,000km on the odometer. WTF? any suggestions or help. The error that came up was "gear ratio monitoring during gearshifts 5 - >x" and "ICM - direction of travel cannot be determined"

How many miles are on the car? Is it possible that ZF still can't build a transmission with valve body components that will actually last the life of the car? I'm going to go out on a limb and guess "yes".

post how many miles you have on the car.

This is the thing, it comes and goes and it's not a continues problem... So the car has 72,000km which translate to about 44,700miles it's travelled in total.. It's not much! Also considering it's just out of the 3yrs warranty by 8months
