VW Passat B7 (NMS) white smoke from bonnet and leaking sound heard from inside.

Hello,
I have Passat B7 live in South Korea. Total mileage is about 120,000 KMs (about 75,000 in miles).


First of all, please watch the videos I recorded:

https://www.youtube.com/watch?v=l_RvJ0Dd6F4 (gas-leaking sound)




This is my third time to see white smoke from bonnet. With white smoke there're more symptoms:

- White smoke from bonnet
- Belt-slipping sound.
: I cannot write it to words, I'm not good at English.
: Engineer said it might be belt-slipping sound.
- Heard gas leaking sound when I'm in car


First time was end of October last year. I was waiting for my colleagues to go business trip with them.
I drove about 50 KMs(about 30 in miles) to get to meeting spot and got out of car with engine running.
After 5 to 10 minutes, phenomenons described above occured.
I was freaked out and could not use my car.

I went to service station and replaced several parts:

- Air-conditioner condenser
- Replenished refrigerant
- Water pump
- Timing belt set
- Operation belt set (I'm not sure this is right word)
: Timing set, V-Belt, Tensioner


Second time was December last year. I was waiting for getting in parking lot of deparment store. Same phoenomenos occured.
I want to same service station next day, but they didn't know what causes those problems.


Third time was last friday. The phenomenons happened again. ***.
I asked these symptoms to forums in South Korea, no one said clear causes.
Today, I'll go to service station again.


Is there anyone know what is wrong with my car..?

Thanks.
