Yes, that is a 7A, great engine when bored and stroked out to 2.5 (83x92.8). That screw is the Co adjusting screw and should not be altered without thee use of a 4 gas analyser, the removal of the fuse on top of the fuel pump relay and a diagnostic computer running but often VAG-COM refuses to communicate with these, I end up using my old Omitec Omiscan.

They are on the right side of the block under the exhaust as far as I can remember, I will check.
