Hi there, With a little one on the way I finally made an upgrade and got my mrs an A4 56plate avant Sline SE 2.0TFSI. It's a lovely car and love it to bits, it has been blue finned but even before that it returned poor mileage to a tank. Since we have had it I think its been close to 400miles to a tank everytime. Works out to be around 30MPG on most tanks, though we had a bit of a motorway run for 200 miles the other weekend and it went up to 33 average on the tank. This is working it out rather than the dash display. Since we have had it I had replaced the PCV valve as the EML came on, changed the diverter valve and it was serviced before we had it. The temp doesn't sit bang on 90 so I have a new stat and temp sensor to go faults on VCDS. Next steps for me are to check the air filter and the mesh, change the stat and temp sensor to make sure that's reading okay. Though the temp prob flicks from 75-90at extremes. Any help would be great as I'm getting it in the ear for buying a 'rubbish car that's rubbish on fuel'! If it doesn't get better than this I may have to sell my mk4 golf 1.8t aspiring track toy to buy a B6 1.9tdi wagon as the long range car! Cheers, Mark.
