The throttle body boot is the rubber Y hose right into the throttle body in front of your motor. With a vag com you can check to see if any un-metered air is entering the engine. Use a flash light and try to seperate the TBB hose and see if its cracked. They have been known to do that.

Default MAF Spudder Update

I removed both diverter valves and the TBB. The TBB was blown up on the bottom. So I believe that's where the Vacuum leak is so I will order one today. Also the bigger hose coming off of the bottom of the passenger side Diverter valve looks dried so I will replace that also. Another question what sensor sits on top of the TBB? So I believe that my MAF was good the whole time I will keep you posted on the out come. Thanks

The sensor on top of the TBB is a boost sensor for the ECM, it never really has any problems. A new TBB should take care of your problems.

The reason I ask is because it seemed really oily in that boot will that hurt that sensor? And why would it be oily? Thanks

No oil won't hurt the sensor, its normal to have a little oil in the intake system. If there is an excessive amount in the intake lines (like a quart!) then the PCV system is clogged up. You would need to change the valve attached to the back of the turbo Y pipe and all the hoses attached to it. The dealer sells it as a complete set. More than likely you're fine, i usually just take the valve off the Y pipe and spray some brake cleaner in there to clean off all the crusted oil in there.

I am having this same issue, I have not checked the TBB but I will in a bit. I too bought a new MAF Sensor and have the same damn issue. It sounds like a lot of boost is coming out of the atmosphere so maybe I have the same issue.

Did anyone figure out the outcome of this issue?? Thank you
