Golf vi gear indication on MFD

[Brett6R]

Hi Guys
I've searched hi and low for a clear answer on the topic , I have a golf 6 TDI manual transmission which used to show the gear I was in when driving and would suggest a change once you reach the correct rpm for fuel economy , I know it's not important to some when it comes to correct driving and knowing when to change and I can understand that but I want to problem solve this as my specific vehicle came out with this option and it's now missing on the MFD , I know it might seem silly to want to fix such a small problem but it matters to me and I really need to sort it out , I've cleaned the sensor plug on the gearbox with no joy , I am wondering if anyone could assist me with a fix ?
