Unfortunately I only have the Haynes manual for my Mk4 Bora. I have had higher than average fuel consumption and some black exhaust smoke when hot. This is not all the time. Sometimes it runs ok but then others it chews through the fuel. My shareware vag shows faults in the MAF and the Lambda sensor.
The manual is next to useless for the petrol engine emissions but in the diesel section, it says there is supposed to be 12 volts between terminal 2 and 3 of the MAF connector and around 5 volts between terminals 3 and 4. I have the 5 volts but nothing between terminals 2 and 3. Both terminal 2 and 3 seem to be earths as the multimeter shows battery voltage when connected between each terminal individually and the battery.
Any suggestions?
Thanks in advance
