Hi all I am new to this group. I have a 2014 vrs 2l tdi Skoda octavia. My car is lacking power and keeps showing code p0299, I have replaced 

turbo

actuator

boost pressure sensor
map sensor

maf sensor

along with other other sensors changed, 

checked all air lines- no leaks- no cracked pipes

however my car is still under power with glow plug light flashing and engine light on. 

can anyone please advise or had similar problem and how did you fix it

thank

Ideally you need to have your car live data logged to see what it is or is not doing correctly. Has the car been remapped at all? My old mk2 VRS flagged the same code when it was mapped but still drove fine.

Any fix for this issue
