I did a search for this problem with little luck.

My 2013 Jetta Sportwagon TDI dies under very specific circumstances:

The car has been sitting out in the sun all day. It is then started and moved in 2 or 3rd gear around a parking lot, for example. Then when coasting to slow down for a stop sign, I press the clutch in and the engine dies.

I have not been able to reproduce this regularly. I will be taking it to the dealer since it is brand new, but I wanted to know if anyone has any idea what could cause this or how I could reproduce it.

Thanks.
