TCM error software
 

Hi Guys , am new to the forum.

I need ur help my car has problem in tcm software error C30 2008 Turbo T5.
My car has shifting flares and jesk gear 2 and 3
The specialist told me need to update the software only i went to the dealer and to update it but the issue is that they could need perform the update coz it says " 131 A non-compatible hardware part detected for node TCM "
They said i need to change the gearbox which does not make sense to me.

despite i purchased the car from them.

Can anyone help me what i need to do to resolve it?
