First off, let's simply define the OBD-II Trouble Codes:
Yes, 18032/P1624/005668 are the three codes that indicate "MIL Request Signal Active."
So, what does THAT mean (in plain English)??? This means that Fault Codes are stored in the TCM. SO WHAT'S THE SOLUTION?

P0011 - Camshaft positioning sensor
P2181 - Engine cooling temperature sensor.
If you have a repair manual (chilton/haynes/etc) these should be fairly simple fixes.
Camshaft positioning sensor for my car was $35 and took about 15 minutes to change.

2carpros.com suggested the P2181 is also fairly easy to replace

It sounds like either the mixture is bad or you need a new 02 sensor. If you have never replaced the o2 sensor I would get that done anyway. Next I would get a general tune up and have your throttle body cleaned.

02 sensor is 300 try scrap yard 40pound 02 sensor is on front of exhaust 3 wire sensor

You'll need an oxygen sensor tool (wrench) available at your auto parts. The size is standard for all VW 02 sensors.

Check the water pump... the impeller may be loose and the water/antifreze is not circulating.
