Subjective:
2.8 Liter V6 Quattro w/ 90K miles presents with hesitation upon acceleration between 1200 and 2500 RPM, mostly in 2nd (its a manual tranny) and 3rd gear. Symptoms began around one month ago, without provocation. Seems to be progressively worsening. Nothing seems to make it better. Already replaced MAF sensor.

History:
For about the last month, I've endured this new problem without a CEL. My concern was elevated enough to take her into a local European tuner, who ran a VAG-COM. No faults were detected. All cylinders good, no misfires. ABS control module out (for a while). Pulled the MAF...car ran fine without any disruption in idle or acceleration. Therefore, a new MAF was ordered and installed.

Recent:
Just installed the new MAF. Left battery unhooked for about 30 minutes. During the test drive, the car presented with the exact same symptoms as before.

Remote:
Timing belt and water pump replaced at 73K. Tuneup (new plugs) also at 73K. New battery one month ago.

Need help diagnosing this one.
