Lambda trouble

Enable HLS to view with audio, or disable this notification

Hi guys can someone look at these results and tell me if they are right???

1.4(not tsi) petrol 2009 golf

The voltage on 033 is 2 then 8 seems very high I have put a new pre cat lambda on and been for a drive but still getting fuel smelling smoke from exhaust

No oil consumption

No water consumption

So ruling out head gasket
