2014 Sportwagen Sudden Power loss during acceleration.

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.

Take it in to the dealership.

I had this problem, possibly to a lesser extent, on my 13 sportwagen. The egr turned out to be the culprit.

Good luck, happens to mine now and then.

No codes no indication of what causes it.

The general consunsus I've found is "that's just how it is" but it's likely due to the rediculous amount of emissions crap bolted onto these cars.

Exhaust flapper choking out exhaust flow, DPF choking out exhaust flow, EGR, bad fuel, dirty fuel, watery fuel, dirty fuel filter, water in the intercooler, fuel cut due to excessive egts during a regen, and on and on.

Search and you'll find all of those and more as potential culprits with no definitive answer.

I had similar issue.... the result was 5 failed fuel pumps and 5th time they realized why not check the fuel tank? BEHOLD! It was covered with mold/mildew due to sitting 2 years by buyback program. Please have them check your fuel tank.
