Hello everybody! It's me again with another problem!
 

I was driving my Škoda the other day on the highway (1.4 TDI, BMS engine code) and the glow plug light popped up out of nowhere with the message "Engine Fault: Visit Workshop" along with a slight loss of power. The light kept blinking for a few seconds, went away, came back up, and went away again.

After all that, the car drove normally BUT while accelerating (between 2200 and 3000 rpm), I hear a strange high-pitched noise (NOT like a police siren kind of noise), but it is very strange and very hard to capture on video (I will try, though).

Thanks in advance!

EDIT: forgot to say that there is no check engine light.

Check a hose hasn't popped off.
