This bulletin applies to Volkswagen vehicles equipped with the TDI engine, where the customer complains about a lack of power. One area to check is the mass air flow (MAF) sensor reading in the measuring block, group 00, field 10.
The value should reach 255 under full load. If the reading is low, check the air filter and air box for restrictions. If the filter and box are OK, suspect the MAF is at fault.
