Octavia 1z doesnt move DSG keeps revving

Okay, I had couple of issues (yellow electromechanical steering light, loss of power with emissions control message, and airbag faulty message) so I was taking it to a garage today to get it checked and rectified I started off and electromechanical steering warning light got off and I driven around 40-50 feet and i had to stop by for a minute so I put the DSG to Park and again when I was starting I put the DSG to D as usual but when I press the throttle engine keeps revving and wheels do not move. Engine revs to a maximum of 2000 rpms and when I put it back to neutral the engine revs normally (I revved it up to 3500). But in D mode S mode and R mode car refuses to move an inch. 

The second thing I noticed is that my gear shift doesnt feel normal I mean when i take it to P its quite tight and the lever is not coming out as usual unless until I use some pressure to move the stick forward and the lever comes out. 

Hope this isn't some really huge issue.
