Question about 2001 Volkswagen Jetta TDI
2001 Jetta VR6 is dying when I come to a stop; i try to restart but nothing works no lights or anything - and not even a ''click click click'' like when dead batter - eventually it does start up after 5 or more tries; battery and alternator are fine; took to shop & replaced mass airflow sensor & cleaned throttle, but still dying
error codes still coming up from check engine light: 16518/P0134 Oxygen Sensor No Activity; 16519/P0135 Oxygen Sensor Heating Circuit Malfunction; 17511/P1103 Oxygen Sensor Heating; Performance too Low; 16795/P0411 Secondary Air Injection System: Incorrect Flow Detected
Check (ALL) fuses period, and corresponding relays for the Secondary air pump with an amp in the car sometimes these stick or just fail to contact. also make sure your Battery is 100% not 80% have it load tested a weak battery reeks havoc on the electrical system. Also check the ignition and starter solenoid have them all tested also fuseable links this problem sounds to be in the ignition a loose wire on the starter somewhere in this realm. When this happens get under your hood and do a wiggle test. This is a test where you just start wiggling wires everywhere while someone else ids trying to start the auto. I am sure you will find your problem in doing this test. Also when the engine is running do the same test to see of the engine stabilizes to an idle. If you notice any change for the better in doing this test mark the area then inspect it thoroughly for normal electrical problems such as wire loose, chafing, Melted and so on. Your problem may be difficult to find if electrical so make sure you do all harnesses IAC, MAP MAF,ECM etc (ALL) of them you will find it this way.

Sounds like your secondary air system is doing a job on you.Do the following for the secondary air system:
The secondary Air Injection system, this is basically an inspect and replace broken hose detail. leave the inlet hose disconnected and start the engine. Listen and feel for exhaust hissing at the check valves.The check valve(s) will make like a gurgling sound as air is drawn in However , if exhaust is felt or heard replace the valve.
Now with regards to your O2 sensors problems once the AIR is repaired reset the codes and see what happens. Don't forget the AIR directs fresh air into the Catalytic converter. Hopefully you didn't kill those O2 sensors. Good luck

Check for any loose or improperly connected wiring connectors. Some newer cars have lever in the wiring connectors to lock them properly. Also located the computer. Maybe fluids has spilled around the connectors, and caused the problem. These all boil down to bad connection.
