hello everybody i hope i can my problem say with my bad english

in my bmw f10 year 2011 everytime i become a error from my lane change warning and it turned off..

when i starts int he morning the car and i activate the lane change warning with the button everything is ok

if i drive 2 kilometres everything is ok iv i drive 25 km everythink is ok too.

BUT if i turn off the car and then for example on gas station or wherever  and then starts the car again  then i become an error when i drive 70 kmh and the lane change warning  goes off.

the error says me  bad communication with SWW slave  so its the left sensor.

but i think the left sensor is ok because when the car stand a while then all works fine only when the car stay  for few minutes then i have an error. when the car is in sleep modus and i sztart then the car it works good

when you on park LCW is not working its activate but not work
starts working on specific speed and thats why its erroring when starts working

[budddyyy]

yes that i know but at the first start after the car sleeps it works when i drive more then 70 kmh, the error comes only when the car turned off and starts again and when then i drive more then 70kmh

if its stock LCW not retrofit check plug in SWW slave if this not help replace module

it is possible that an impact has caused the slav module to be released from the seat, you have to dismantle it in the rear bumper and check and if it is put back into the seat correctly, unfortunately it is stuck with some reliable hooks

I bought 2 for a retrofit from a seller on eBay for £40. PM for details

i must buy 2 pieces or only the slave?

and is there a different between lci an pre lci model?

a friend buyed one and after flashing it was broke

[DayvG]

I would just buy the slave and code it to your vehicle, I can't see why it wouldn't work. I have no idea if the Pre-LCI and LCI modules are different.

[budddyyy]

ok you think only Vo coding is enough it dont msut be flashed? becauce my master i think has a other istep?
