vag com help please!!
 

I have the p0130 o2 sensor malfunction MIL, so I replaced the sensor and of course the MIL came back. I just bought the car and can't get it to pass with this issue it's a 99 audi A4 Quattro 1.8t. I was wondering if someone with vag com could diagnose the issue? It does have a slight exhaust leak but I'm not sure if its before the sensor. Thanks.

Also the douchebag kid said it has a KO4 turbo but it doesn't have a tune. It also throws a lean condition code.
