Or stuck injector...

he said he smelled when waiting for tow truck this is my guess too

go to the cluster of connectors on the drivers side under the intake manifold. the largest connector of the 3 has the fuel injectors in it. disconnect it and probe top pin to bottom pin with a multi meter across the connector. the resistances should all be similar. if one is shorted or open thats a dead injector.
spec i found in the MM says resistance at the injector at 20C should be between 12-20 ohms

Does the tach bounce when cranking?
G28 engine speed sensor is on the front of the block. probably going to have to pull the throttle body pipe to get to it.
other thing to check would be (sorry it sucks to read, but its the best i could do):
3.5.23 Engine Speed Sensor, Checking
Note
Use only gold-plated terminals when servicing terminals in the electrical harness connector of the Engine Speed (RPM) Sensor -G28- .
Special tools and workshop equipment required
♦ Multimeter.
♦ Wiring diagram.
Test requirements
• The Motronic Engine Control Module (ECM) - J623- fuses OK.
• Battery voltage at least 12.5 volts.
• All electrical consumers such as, lights and rear window de‐ froster, switched off.
• Vehicles with automatic transmission, shift selector lever into position “P” or “N”.
• A/C switched off.
• Ground connections between engine/transmission/chassis OK.
• Ignition switched off.
Function
The Engine Speed (RPM) Sensor -G28- detects RPM and refer‐ ence marks. Without an engine speed signal, the engine will not start. If the engine speed signal fails while the engine is running, the engine may stall.
Test procedure
– Perform a preliminary check to verify the customers complaint. Refer to ⇒ “3.1 Preliminary Check”, page 8
Start diagnosis
– Connect the scan tool. – Start the engine and allow it to idle. – Using the scan tool, check the engine speed:
– Switch ignition OFF.
If the specified value was Not obtained:
Checking internal resistance
– Disconnect the Engine Speed (RPM) Sensor -G28- electrical harness connector .
– Using a multimeter, check the Engine Speed (RPM) Sensor - G28- terminals 1 to 2 for resistance.
Specified value: 650 to 1100 Ω
If the specified value was Not obtained:
– Replace the Engine Speed (RPM) Sensor -G28- Refer to the Repair Manual.
If the specified value was obtained:
Checking wiring
If the manufacturers test box is being used, perform the following step.
– Install the test box.
If the manufacturers test box is not being used, perform the fol‐ lowing step.
– Remove the Motronic Engine Control Module (ECM) -J623- . Refer to the Repair Manual.
– Using a multimeter, check the Engine Speed (RPM) Sensor - G28- electrical harness connector terminals to the Motronic Engine Control Module (ECM) -J623- electrical harness con‐ nector terminals for an open circuit.
pecified value: 1.5 Ω Max.

the specified value was Not obtained:
Check the wiring for an open circuit, high resistance or a short circuit to Battery (+) or ground.
Check the electrical harness connector for damage, corrosion, loose or broken terminals.
If necessary, repair the faulty wiring connection. the specified value was obtained:
Remove the Engine Speed (RPM) Sensor -G28- and check the sensor wheel for proper seating, damage and run out Refer to the Repair Manual.
If the sensor wheel is OK:
– Replace the Motronic Engine Control Module (ECM) -J623- . Refer to the Repair Manual.
Final procedures
After the repair work, the following work steps must be performed in the following sequence:
1 -
2 - 3 -
Check the DTC memory. Refer to
⇒ “3.3.3 Diagnostic Mode 03 - Read DTC Memory”, page 13 .
If necessary, erase the DTC memory. Refer to
⇒ “3.3.4 Diagnostic Mode 04 - Erase DTC Memory”, page 14 .
If the DTC memory was erased, generate readiness code. Refer to ⇒ “3.2 Readiness Code”, page 8 .

Here you go buddy:
Confirmed: Engine Code CCTA
VW has issued an extended warranty coverage on the Intake manifolds as of 02-19-2010. Coverage 20130515
This warranty will be good until 02-19-2020 or up to 120000 miles, whichever is first.
The fuel injectors have been covered up to the same time or miles - Coverage 20130516

Ready to race!
Should still start with a bad intake. My guess is either a chain tensioner or a injector stuck open flooding that cylinder.
