This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Warm or cold engine. Light throttle use similar to in town and highway driving conditions any gear (in manual transmission) around 10-40 mph steady speed and when transitioning from acceleration to coast to acceleration, and occasionally under hard acceleration car seems to "hiccup" or lose power and go through a throttle cut and follow on "confused" state (pulsing on and off the throttle) requiring the operator to let off the throttle until it stops being "confused". could cause accident due to inability to accelerate if needed or unexpected "hiccup" causing someone who is being tailgated to be rear ended. Through checking publicly available forums I have found several complaints from users with responses indicating owners of this model tdi motor may be experiencing these same symptoms and when taken to VW (according to online forums) can take anywhere from 1 day to 1 month for them to come back with "we don't know what it is". software fixes when done do not seem to fix the issue completely (acording to forums) nor does "purging" soot by doing high RPM (above 4000rpm) appear to fix the issue permanently with the issue coming back afterwards. Through commuting in my vehicle ~1500 miles per month I experience the pulsing every day at all speeds from 10-40 mph with low/steady throttle input when maintaining a steady speed. I also experienced the "confused" symptom today after an emergency stop at highway speeds necessitating a hard acceleration afterwards which I could not complete due to the engine cutting and acting "confused" around 3000 rpms in 3rd gear. Symptoms do not appear to incapacitate or immobilize the car and appear to be more of an "annoyance" but could effect safety and long term reliability with the constant loading and unloading motion of parts in the drive line. No indicator or alarm lights lit. Google tdi hiccup and 2013 tdi hiccup for forums
