I Dec 19th 2011 I experienced what I believe was a hard start. Weather in the morning was in the teens, afternoon in the low 40s. Leave work, get in car, put key in ignition & turn to on position, put seat belt on, and start. Car starts right away but is idling rough, shaking violently like a washing machine off balance. I drop into neutral and rev it up to 2k, still idles rough for about a minute more but does not stall. I experienced something like this once when my Subaru legacy's #2 injector quit, a misfiring boxer engine does not idle smooth. The ride home was uneventful, stopped at the bank and restarted fine. Everything was normal this morning, temps in the low 40s. What I believe happened to my car was moisture accumulated in the inner cooler and was ingested into the intake tract causing a "hammering effect" as the engine tried to compress this moisture. Vw has issued a TSB #21 11 06/2025464 but no recall as yet. When I brought my vehicle in for service they found no moisture so nothing was done. I believe this to be a safety issue because the vehicle could ingest this moisture at any time without warning causing the car to stop and strand in an unsafe location. A recall and fix should be issued.
