Default Vag Com Help July 17th midnight

Hay Guys and Gals
LurkerMike and I will be diagnosing my 2000 NB with the help of a vag-com, which LurkerMike is bringing over to my place. We both are new at doing the decode thing and would love to have the help of everyone and anyone who has worked with a vag com. We will be posting the codes and asking for help from ya'll.

My NB has no power and is hard to start. I have R&I the intake and cleaned it, cleaned the egr, changed the vacuum lines, cleaned the IC, checked all electricial connections, replaced the fuel filter, primed the IP, replaced the battery (it just went bad, nothing to do with this problem), the turbo seems to be working, when you take the hose off the egr there is lots of push, the actuator on the turbo is moving about 3/4 of an inch, replaced the MAF as it was throwing that code with an OBD.

The problem started gradually with two or three limp modes, than just driving down the interstate it went into limp mode and has not came out. Yes there is lots of white smoke on start up. Now no power over 2200 rpms.
I don't baby this beauty, always about 80 in 4th while getting onto the interstate. It is meant to be driven hard.

This will be fun and interesting for all of us who have not worked with a vag-com before, we will be giving step by step (play by play, blow by blow) results as we go through this process.

Stay tuned, same bat time, same bat station, tomorrow night at the witching hour of midnight. Hope to get lots of ya'll looking and making suggestions. We will look at them all and answer as we can.

Thanks in advance.
P.S. Midnight July 17th EDT.

Thanks for the input, as of yet I have not replaced or cleaned the N75, I think that may be the problem, just wanted to wait for the vag com before throwing more $ at it.
I will steal the one off LurkerMikes car to check it out, don't tell him he doesn't know that yet. ops he will read this thread won't he?
how do you clean it?

I have used the dielectric on it and no differance. Anything else or can I tear it apart and clean it. I seems to be holding a vacuum, with a vacuum pump it does not leak down. Could a bad N17 make it run this way?

P.S. The onset of power loss was gradual and the battery was found to be outputting only 11 volts.

The battery was replaced yet the power loss remained.

We cleared the codes and they did not return yet it was hard to start and was still way down on power.

VAG-COM showed a good fuel balance between all 4 cylinders but the IQ was 9 - 10. The timing was under the upper green line, about half-way from the center blue line to the green upper line.

There was no noticeable blow-by from the dipstick tube.

I did not think about checking the voltage while I was there to verify the alternator was putting out at least 13.5+ volts.

What's the deal with the mash the throttle down and hold it to reset the ECU deal? Could that help?

I don't know what the MAP/MAF should look like or what else to look for?

We didn't swap n75's... I didn't think about it and after meeting me he probably did not want to risk me getting stranded for the night... or three...

Lurker is so full of s88t, he is a great guy to get to know. He can all the way from Atl to Rutledge with his trustie vag -com in tow, spent 3-4 hours showing me the ropes and on top of all that is a really nice (sic) guy.
Thanks publicly Mike I know I will see you again soon.
If anyone has any suggestions please chime in.
I probably will tow it to Roger next week if no one can come up with an answer from this forum. Roger is booked for the next week or so.
I want my NB back.
Mike the stars are great in the country, aren't they!

I forgot there were stars in the night sky... heck, I even had forgotten the night sky is supposed to be black and not a light shade of pastel baby blue...

Bro
David moved to Philly about 4-5 months ago, he was the one who looked at and took care of this NB, when I needed something done.
