The Hill Climb Assist (HCA) is only a low range gear feature and does not seem to be a shipping feature on US cars. The US website considers this feature a "delayed introduction" item. Can anyone verify whether this is on their US car?
My car's VIN ends in 40xxx which was manufactured in 11/2003. The window sticker that came on my car does not list it in the "Performance and Handling" section of the standard VW sticker. However, my window sticker mentions all the other three letter features: HBA, EDL, ABS, ESP, EBD, EBA and ASR. Unless your VIN is higher than mine, it is unlikely that your car has this feature (if you have a US vehicle).
