So Iv tried to do basic settings and even that does not work despite following correct procedures this time.
Spoken to a VW tech mate of mine who suggests that the clutch or the actuating mechanism from the mechatronics is faulty in some way and that is nothing basic settings will fix.
With all this news, and the fact gearbox was unused dealer stock, Iv lost faith in this gearbox. I shouldn't be the one to fork out repairs for gearbox that should be fully working. Mechatronics are a 4 figure sum and clutch is around £400 for LuK Repset so its a false economy to try and repair it and I couldnt repair it with my limited expertise so gearbox specialist's labour would be on top.
Asked the seller to repair it or give me a full refund, awaiting their reply but either way the gearbox will have to come out again and await repair/look for a replacement box
Iv come tooooo far to put the manual box back in. I knew something would inevitably go wrong due to my mistake but the gearbox seems to be the faulty piece of my DSG coversion project. FFS!
