AUDI A3 SENSOR PROBLEM

2006 Audi A3 • 70,000 miles

I have sent my audi a3 2006 with 150000km on the clock in for a diagnostic. The following codes were returned:
16825 - evap emission control system incorrect flow
18610 - sae system too rich of idle bank
17748 - cam shaft sensor (640) eng speed sensor incorrect

The reason the car was sent to a diagnostic is because after a wheel alignment was done after about 200m, when I stopped the car stalled the moment it idled. This only happens whenever I stop I need to keep my revs up so it doesn't stall.

The mechanics have not said what the issue is and want to charge me more money so they can look further. Please could you tell me what the possible problems are that could be causing this?
