Wanted to share my experiences with this. I had several instances which I assumed were caused by the intercooler icing/water ingestion. In short, car would start normally and then shut down within a second or so and then on the subsequent start, car would crank normally, start and then run rough but recover in a very short time. Most recently it happened when I drove to work in sub freezing temp with rain/snow and then parked at work. Temps rose through the day and problem would occur when I went to start vehicle to go home. Maybe two times in the last month.
I took the car in for its first 10,000 mile oil change and let the service advisor know about the problem, I also typed up what exactly was happening and included the TSB for the tech. Received a message on my phone the car was ready to pick up yesterday and said something was replaced/installed and the tech wanted to keep the car overnight from the previous day, but the message was vague. Picked car up this morning, looked at invoice and it stated "customer states the car is running rough, hard start, runs rough for 30 seconds- stalls after a few seconds, was raining snowing out. Road test ok, checked GFF no faults, checked TB found one for that concern, performed TB211301, installed intercooler kit"
I was surprised it was done considering many dealers can not duplicate and therefore won't install. I do not know if anything was found in the intercooler lines. They must of had the kit in stock as there was no wait for it nor did they tell me they were specifically installing it.
Dealer was Douglas VW in Summit, NJ. Specifically took car there instead of original purchasing dealership as they have good service reviews. Oil was also changed with proper gold bottle 507 Castrol. I am very pleased with them.
