Hi All My A6 lost all drive in any gear after popping out of 3rd gear one day. I thought the box had grenaded as I had lost 4th and 3rd/5th had whines. Clutch and master were replaced with SACHS items about 4K previously. I have just replaced gbox and I’m still in the same position, can’t get drive in any gear. I have changed the master back to the old one and bled system but still no joy!!!! Please help?!?!?
