Hello All. ... the MAF sensor ...As I read through the diagnostics I saw that the computer automatically resets the fuel management to whatever reading it was at just as the wire went open. Though I wasn't seeing smoke, I'll bet the wire broke at cold idle which would account for the poor fuel economy. ...
Bruce,I had a similar thing with my 04 TDI. The check engine light came on, and the Advance Auto code reader indicated MAF sensor and EGR valve, but my power loss and slow acceleration felt like a clogged fuel filter. I replaced the fuel filter(It might have been in-line for over 75K?) and my power and acceleration returned, but the check engine light was still on. After driving about 50-60 miles, the check engine light went off by itself. In this case I am glad that I followed my "gut" and procrastinated buying the MAF($$$$$).Steve
That's what I like about you Gary--always looking out for the welfare of others. How about letting me hook up my scanner on your bus? It won't communicate but then I'll only charge you $100 which is half the going rate so it will be a good deal. Jack
