So I recently broke down with what I thought was a bad fuel pump. Had the car towed because it just wouldn't turn over. Got it home and installed a new lpfp and new fuel filter. Car ran perfect for about 2 weeks and then clapped out on me again with fuel pump message on the Idrive. I have had the mhd stage 1 tune on the car when this all took place. Once it wouldn't turn over( after the new parts) I flashed it back to stock and 2 hours later the car turned back on and I drove it home. The codes that showed up when the pump failed were 29DC, 29F2.
wondering if any one else is having these issues, and where i go from here with this thing.
