Carly error code: 005139

Hey Guys,

I ran a diagnostic with Carly tonight and I got the following error:

Transmission Control
Transmission / Getriebe GS 19
sorry, unknown fault
Code: 005139



Now I have noticed that when I get to an intersection at a set of traffic lights and I bring the car to an almost dead stop and then try pull away again it has quite a pronounced hesitation and then pulls off. I know my intercooler has a very small leak in it as I filled it with water 2 weeks ago to check for boost leaks and it has a tiny hole, however the car is still managing to reach 9.5psi with stock everything! no software etc.
So I am not sure if that is causing the hesitation, it doesn't seem to have any problems with top end power or reaching peak boost so I am not sure what is going on but this transmission error is concerning me.

I have got an aftermarket big intercooler that I will fit to replace that leaky stock intercooler however it means I have to fit my after market charge pipe too and its allot of work so I need a weekend where I am free to do this.

Please can someone in the know give me some insight.
