PO455 and exclamation mark
hey guys just wondering if anyone has run into this problem . Car is running fine but had a check engine light come on and then after a short period of time a red exclamation mark light up on the left side of the instrument cluster. has anyone had the same problem. For now i cleared the code and the light is staying off. anyone had a similar issue?

Check the connector on the right side of the throttle body. There is a fuel vapor line with a solenoid/pump. Unplug the electrical and re plug it. If not, is that part... like $300 +/-

FWIW:
P0455
Leakage in fuel tank system
Diagnostic conditions
--Vehicle speed = 0 km/h
--Engine speed = 0 rpm
--Correction factor, height > 0.73
--Coolant temperature upon starting the engine may be no more than 6.8 K above ambient temperature
--Coolant temperature when engine starts > 3.8 °C
--Period for which the engine needs to have been running before ignition is switched off > 20 minutes
--Ignition has been switched off for at least 10 seconds.
--Ambient temperature 4 … 35.3 °C
--Active charcoal filter load < 3 for minor leak
--Fuel tank fuel level 10 … 54 litres
--Battery positive voltage 11.02 ... 14.5 V
--No fuel tank filling
--No faults detected for ambient pressure sensor, coolant temperature sensor, vehicle speed sensor
--No output stage faults detected for DMTL pump motor, DMTL switch-over valves and tank vent
--No fault detected for tank vent (flow)
>> The diagnostic conditions can also be established using the PIWIS Tester via the short test "tank leakage test". After the test has begun, the ignition must be switched off.
NOTE
In this context, please also observe the function description.
Possible fault causes
--Tank cap not closed correctly, leaking or missing
--Purge air line leaking
--Tank vent leaking
--DMTL (Tank Leakage Diagnostics Module) leaking

If you are not aware the red exclamation mark is to alert you to a new fault code or change in computer programming. I believe the mark would go off after a period of time without resetting the code and would light up if a new code was triggered.

well i cleared the code 400kms ago and it still hasn't returned. Hopefully it was just the fuel filler cap not completely seated although when i checked it seemed to be just fine
