So, background on the car and its current maintenance
2001 Golf TDI
150000 kms
Automatic
The car currently gets an average of 30-33 mpg (~700 kms per full vented tank)
Steps taken to increase mileage
1) Timing belt done (timing is slightly advanced but within spec)
2) New fuel filter, air filters
3) New OEM nozzles
4) Brakes do not drag
5) tires inflated to 90% of max
6) Snow screen is clean
7) Replaced all vacuum lines
8) thermostat is okay, tested with thermometer
9) intake is clean
Driving habits are extremely good. No stomping on the pedal what so ever.
Don't know what else it could be.
Testing the MAF, i unplugged it and the car seems the same. The only thing i notice is the lack of power above 100 km/h. Car struggles to get past 110. But the mileage seems correct. It gets 45 mpg with it unplugged based on the scan guage. Is the MAF slowly failing.
With the MAF plugged in, at 60 km/h in 4th gear, the scan guage reads around 55mpg. but once you get up to 100 km.h, its sitting around 30. meaning if i was doing only highway driving, i would get 30 mpgs. something is wrong.
