Codes from 2003 VW Beetle 2.0L manual transmission
I've got a 2003 VW Beetle 2.0L manual transmission that I picked up a couple months ago. After driving it for 50 miles the check engine light when on. I scanned it with a VAG-COM and got the codes below.
I reset the codes and drove the car for another 800 miles before the check engine light came on again. The car runs fine. The only notable exception is that sometimes when I'm driving on the highway in 5th gear the engine seems to slow down for a few seconds before it picks back up and it kinda jerks when it picks back up.
I climbed under the car and was able to locate the Engine Speed Sensor close to the base of the oil dipstick. I may be able to disengage the harness and get to the bolt without taking anything off. I'm wondering if replacing the Engine Speed Sensor (CKP?) would solve the P0321 or if there's anything else I should check first.
I'm wondering if anyone has seen this before or might have some wisdom they can share.
Much appreciated!

Welcome to the forum. 
That's an old VAG-COM Version: Release 409.1-S

That's an old VAG-COM Version: Release 409.1-S
VAG Error Code: 16705
EOBD II Error Code: P0321
Fault Location:
Engine Speed (RPM) Sensor (G28) - Implausible Signal
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Engine shuts off.
Engine doesn't start.
Speedometer inoperative.
Glow Plug Indicator Lamp (K29) flashes.
Engine Speed Sensor (G28) loose.
Engine Speed Sensor (G28) faulty.
Possible Solutions:
Check Engine Speed Sensor (G28).
Special Notes:
The Engine Speed Sensor (G28) is also used as a reference sensor for the crankshaft position and correlates with the Camshaft Position Sensor Bank 1 (G40) and Camshaft Position Sensor 2 Bank 2 (G163).
When found in a VW Golf/Jetta (1J/9M) or Audi A3 (8L) with 1.9l TDI-PD (AXR), check Technical Product Information (TPI) 2007067 which explains issues with electro magnetic interference. A modification to the wiring will fix this problem, extensive details can be found in the named Technical Product Information (TPI). Even though this Technical Product Information (TPI) was originally released for VW Golf/Jetta (1J/9M), a customer of ours came across the same issue on an Audi A3 (8L).
When found in a 2004 VW Golf, Jetta, or New Beetle with 1.9l TDI-PD (BEW), check for Technical Service Bulletin (TSB) 2010461 (01-07-45 formerly 97-05-03) or 201463 (01-07-44 formerly 97-05-04) calling for a flash update to the Electronic Control Unit (ECU) and a secondary ground installation.
When is the code detected?:
The P0321 code is triggered when the Engine Control Module (ECM) detects the signal is out of range.
Description:
Ignition failure sensor is used to check whether the spark ignition is occurred correctly or not and also used to tachometer drive. The sensor monitors the voltage difference between a resistance which is on the battery circuit for ignition coil. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. This is confirmed for every ignition event with the crankshaft sensor and the camshaft sensor. If Engine Control Module (ECM) detects a malfunction, no ignition is possible, so the engine would not start. If there is no ignition signal for a predetermined cycle for one or two ignition coils, an ignition coil circuit failure exists.
You can use Read Measuring Value Blocks (MVB) to read the signal from Engine Speed (RPM) Sensor (G28).
