I have an 2003 Jetta, automatic TDI with 165000 miles on it, I've only had it for about 3 months and checked the MPG on the last 2 tanks of fuel and it is only getting 30 to 31. Ive put on a new timing belt, changed oil with synthetic, new air filter. The car runs good not slugglish with no TDCs. I am going to run some Lucas injector cleaner through it to clean the injectors and pump. Can anyone steer me on the next steps too get the MPG up or should it be better than 30 MPG. Also I do not have the program to check the timing with but do have access to a Modis but I am not sure if it has the ability to read timing. Does anyone know if this is possable with the Modis?
