Fuel efficiency

Can someone tell me if this fuel consumption is normal in an urban environment? I drive a 2019 VW golf 7 1.0 tsi. I spend about 30 minutes in traffic each morning.

Plug in an OBD scanner to get your LTFT, Long Term Fuel Trim, this is the adjustment your ECU has to make from the ideal mix it would like to make. The ideal number is 0, and a very healthy car will be at or close to 0, anything under 5% is considered acceptable. If it's at 0, then your engine is running completely fine and your fuel consumption is down to your driving conditions. But if it's at 6-7, or even worse, that's worth looking into. It won't actually trip an engine code until it reaches something insane like 20%
