Fuel consumptions,
It burns 20 liters per 180 km,
I've replaced the throttle body unfortunately same results!
I placed new exhaust but still same problem
I think it is the O2 sensor, but how can i get sure?

What type of Fuel Injection System is in your Golf? Post a picture of the engine bay so I can see.

We don't have the 1.4L engine here in North America.

Check:
- fuel pressure
- coolant temperature sensor
- disconnect the O2 sensor to see if there is a difference
- Vane Air Flow Meter? MAP sensor?
- 4 Injectors? Throttle Body Injector?
- check the fuel pressure regulator vacuum hose (if it has one) for wetness

Waiting for your picture(s)...
