My alh jetta with the notoriously terrible 01m auto has always gotten really poor fuel mileage. Last tank I averaged 24.8 mpgs (mostly city/some highway) which is pretty embarrassing. The tank has a "ventectomy" so I fill it all the way to the top every time and am pretty confident I am calculating fuel mileage correctly. It runs great. The egr was removed and cleaned thoroughly as well as the beginning of the intake(where I could reach with the egr removed). It was pretty clogged, so I wouldnt be surprised if the intake manifold is clogged further down. I kept the egr off for a year in favor of a "race pipe" hoping to clear out the intake but saw no improvement in fuel economy or power. The brakes aren't sticking, I checked and adjusted timing with vcds (was advanced off the chart, now is dead-on), and replaced the injector nozzles. The new injector nozzles are way better than the stock ones, but my fuel mileage has remained the same. I don't expect to get 50 mpg with the automatic obviously but 24 is a little ridiculous. Eventually when I get my hands on a good donor car I'll swap the tranny. Any input would be appreciated, thanks.
