A guy in my area helped me out bigtime...

Here's the codes I pulled...

Low voltage (I need a new battery)

MAF sensor (I'm going to clean it and see if that works)

boost limit exceeded (this is the one I don't know how to fix)

We cleared the codes and I had my boost back but as soon as I pulled out of his driveway and sped off the boost got shut down again, I have a sh*tty DV of ebay now (I think thats the problem) and a 710N in the mail (tuesday). I've replaced the vac lines that were frayed and leaking. I'm getting a new battery and will I get my boost back after i replace the DV and clear the codes again?

Any suggestions on how to fix these things? Help is appreciated! thanks!

 

might be your N75 valve

 

any idea where I can get the N75J valve? I've found the H but heard it has a good chance of not working with my car in particular. thanks

 

How do you plan on cleaning your maf???

 

I heard you flush the sensor with rubbing alcohol or some kind of cleaner.. I read about it on here but not sure exactly what the method is I'll have to look into it tomorrow at work...

hhahaha I work for the government

I ordered a N75 from ecs... do you think that will make a big difference? I will have to clear the code again right?

Does anyone know where to get the N75J valve or do they cease to exist?

 

Here is the exact log from the VAG tool... any inputs are apprecaited greatly

you can get either bale at the dealer for like 60

 

MAF is covered under warranty up to 80 or 88k miles. dealer wont charge you to replace it

 

The low voltage code usually just means the battery or ECU was disconnected. That code will not limit boost. You can check to see if your MAF is limiting boost by disconnecting it. If you have normal boost with the MAF disconnected, your probolem is probably the MAF. Don't run your car with the MAF disconnected for too long. It will run really rich and stain the crap out of your bumper.

Before you replace the N75, check the connector and condition or the wires going into the connector. You'll need to pull the boot off the back of the connector to inspect the wire. The wires are known to break at the connector.

 

hey thanks buddy! I appreciate the help any idea what the third code is? when I cleared the codes I had my boost back until I pushed it... then I literally felt it go into limp and the limp doesn't go away when I turnoff and restart only when i clear codes or disconnect battery... is that race valve related? I will inspect the MAF and the original race valve... preesh!!!!!!!
