Dear Siena,

I have a VW passat with the following details:
01) VW
02) Passat
03) 2.0 turbo petrol
04) 6 speed automatic
05) 2007 model
06) milage 92000

I am experiencing the following problems:
1. The engine starts with the one push of the start button but struggles to stay on as if it does not
have enough air.
2. Once in motion there are no issues except for the whisling sound that comes from the front passenger side
as you step on the gas pedal.
3. Finally, the AC cools very well when external temps are low but in the heat of the day the cooling is very low.

Siena, what do I do to solve this problems.

Regards
John.
