When engine is cold glow plug warning light comes on when you accelerate hard, and seems to go into limp mode. If you pull over and turn engine off and restart the problem goes away. It a octavia 1.9 2017 diesel. Has anyone else had this problem? 

Tried an OBD2 reader to see what the car thinks is wrong with it?

Mine flashes dependent on ambient temperature as it has a weird glitch with an EGT sensor and ECU.
