My Jetta swap MAF (image of another Jetta swap MAF): is located lower than OEM (Jetta) position (image looking up at my intake, MAF on RH): so may be more prone to oil fouling than in the original Mk3 configuration. That said, I haven't noted any fouling issues and usually clean it when I replace the air filter. David's comment below makes me think that "yes", it burns off any oil during use. There is a protective mesh on this MAF. The Jetta engine management uses a wiper & resistive strip in the throttle position sensor. It is similar in function to the WBX AFM strip, but is smaller with only 3 wires (in manual transmission form). It tests in a similar fashion to the AFM on a WBX but I have yet to put an analogue meter on it to check for dropouts. Neil.
