2005 MK4 BEW. Our MAF sensor seems to be lazy based on plotting the output at full throttle in VCDS. It spikes over 900 then diminishes to under 700 while holding the pedal to the floor the whole time (15+ seconds). Turbo is showing great >2000mbar and boost specified follows boost actual very closely. No codes.
So having nothing to lose, we took the sensor out and tried to clean it. No improvement at all (I didn't have much hope anyway). But I found that it appears to be missing the little diode thingy on the side:
Isn't it supposed to look like this? Or is it different on our model?:
I looked could not find this missing diode looking thing in the air passageways or air filter, so either its not meant to be there or it had fallen out a long time ago. Anybody thoughts?
