Make sure coolant level is as it should be. If level is low look for evidence of leak(s). Top off fluid if necessary. The engine coolant temperature sensor is a very common issue with these vehicles and may be the cause of your issues if no leaks are found. Also a faulty thermostat cans cause the sensors to read voltage high but most likely a sensor issue. The sensor is a potentiometer (variable resistor). The computer sends 5v through one of the wires this voltage goes through a resistor which will vary the voltage based on temperature sensed by the engine coolant temperature sensor. The sensor has a negative temparature coefficient meaning the resistance will go down when temperature is high and up when temperature is low. The less resistance the more of the 5 v gets back to the computer. The PCM detects this high voltage and set the check engine light on warning you of an issue. Whe this sensor goes bad it is usually accompanied by temperature gauge fluctuation or erratic operation and the cooling fans run long or all the time even though the vehicle is cold. Hope this helps.

SOURCE: My car is running codes P0011 and P2181. Can you

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

How do I build/repair a damaged wiring harness for a 1984 VW Jetta GL 1.6L non-turbo diesel 5 speed, manual steering?

You could try to just cut out the bad part and solder in the new wire to the good part of the old. Also clean up the affected area.

Valve job for 2000 VW Jetta GL w/105,000 miles

is he sure it isn't the rings are worn also?  If so don't waste money on a valve job, when you really need a rebuilt motor.  Had you changed the oil more you wouldn't need this repair at this time.  Good uck as his price is decent.  Ask him the price for a long block?
