986 Tiptronic Emergency Run, please help

[indoboxster]

Hi all

i just bought 2004 986 boxster 2.7, and right now the "tiptronic emergency run" warning always showing up.

when first i bought the car, the "tiptronic emergency run" sometimes show when i'm driving in the middle of traffic and when i am free from the traffic to restart the car the warning goes off. So i took it to local porsche workshop and ask about it, they said i need Transmission switch replacement and some fluid change so i do the transmission switch replacement and transmission fluid also.

after couple a days out the shop the car is fine no warning showing up, and yesterday the warning comes up again even when i first started it and this time the gear change feels rough

i already restart the car and disconnect the battery also, but the warning stand still

is anybody here ever had an issue like this? please help

sorry for my bad english, hope you guys understand what i said

thanks
