My 2014 TDI Sportwagen has developed troubling symptoms over the past 2 days. It has a sudden, but brief, power loss under acceleration. Usually accelerating from a standstill the car's power will drop of alarmingly, shudder twice, and then resume abruptly. It runs great, otherwise. It has done this maybe 4 times in two days? I've had the car less than 6 months. I am the second owner, bought it as a CPO with 37K on it and I just tripped 50K. It was serviced at the dealer about 2 months ago. Again, this problem just cropped up. I've poked around a bit and see that both fuel filter problems, transmission issues and a cam position magnet are potential culprits? I am utterly new to modern VWs, modern diesels and DSG transmissions, so forgive my cluelessness, I'm learning over here.
