Gearbox codes

[H15DTL]

Hi can anyone tell me what the code for my gear box is please? It's the 54 ref Leon tdi 150 6 speed box? I know some codes are o2o & o2y just wondered which one mine is?
Many thanks

Got the same car & year. I think the 6-speeder code is 02M.

02M is a generic description, but does not define the ratios. Your gearbox is likely to be ERF or FMH, but I don't know which. My build sheet doesn't tell me either, and I can't find a marking on the box itself...
