The radio is in Lock-Out mode. You only get two attempts to enter the code, then it enters Lock-Out mode. Put the key in ignition and turn on the radio for an hour (maybe a bit more). The radio should reset itself after about an hour and then you can re enter the code.
P0016 refers to the Cam shaft sensor and crank sensor not in sync , the P0011 refers to Variable Valve timing and Variable Camshaft Timing , as the P0016 has shown i would expect that is the issue between these sensors and the PCM , dont waste your time and money on trying to get a cheap fix this is a know issue with VW and a VW dealer will have the appropriate equipment to readily rectify the issue, i think this link will show why is best to go to a VW dealer, but the choice is yours , incidently there is no need to check for electrical issue as is a component based issue so a waste of time and money if your mechanic does the se first tests

Autodata publications show it as a timing belt
recommended timing belt change at 80.000miles
this is qualified by driving conditions , highway speeds , dirt , dust and oil leaks all of which will drastically reduce the service life of the belt
the engine is identified as an intereference engine which means valve damage if the belt breaks or the replacement is not done according to correct procedure
the labor time in an accredited service shop is listed as 3.8 hours
if you have been having the services done according to the service book it should be correct in what has been ticked
you can always verify it at a service dealer shop
as the manufacturer runs engine with both chains and belts , you can verify it is a belt if it has a plastic cover over the area of the timing belt.
if it is a chain it will be a full metal cover
If the radio is an OEM Volkswagen can give you the code using the VIN number. If the radio is not the original the only way you'll be able to get the code is from the manufacture using the model# and the serial number.
