We had that conversation already, in another thread. This thread is mostly about testing fuel economy by removing EGR, changing nothing else. Instrumentation with the SG is unfortunately problematic, so ABA testing is going to take a while, especially in winter where my biodiesel ratios, ambient temperatures and warm up time vary.
However, if I can verify my defeat circuit emulates the lack of EGR accurately, perhaps the SG can be used as a guideline. I'll have to see, right now I still get an occasional P0402 code, so I need to hook up the VAG COM to see if the expected MAF is too high or too low over the operating range.
