I have some problems with my 2009 Passat CC 2.0 125kw. At some point the car looses performance then i see some flashing lights, see video :

youtube.com/watch?v=FZXeVogTR-A&feature=youtu.be

Also the car acts like it has half of it power. Between 1000 rpm and 3000 rpm it is like it has half of her power.

Error :
000665 - Boost Pressure Regulation P0299 - 000 - Control Range Not Reached

Full report : pastebin.com/0QAPH9kJ

What can it be?

Thank you.

My TDI did that every time I washed the engine compartment, something shorted
when it got wet. A real heavy rain would cause it too, but once it all dried
out it was finre

It's an under-boost condition, check for leaks after the turbo.

If it's all tight, then sensors.
