2005 Jetta TDI, BEW engine suffering intermittent power loss, I recently replaced the MAF sensor and I am still getting a low voltage code. I just bought VCDS a few days ago so I'm not really sure what data would be best to obtain, but the engine codes are:
Here's something I noticed that might help narrow it down, there's a hissing sound coming from the exhaust when it has normal power, then it will change to a deeper tone and it will have no power. This is also when the MAF goes to zero. I made a log on VCDS while idling, not sure what information would be helpful but at least it's a start.
