O2 sensor signal stuck lean; bank 1 sensor 2 issue.

[Abertawe1972]

Evening everyone.

Just purchased a 2015 Audi S7 V8 450bhp petrol with 96000 miles, lovely car but has just thrown up the error on my ODB2 o2 sensor signal stuck lean; bank 1 sensor 2. Is this an easy fix to do at home, or a garage job? If it can be done at home where can i find it?

Thank you.

If bought from a dealer they should fix this free of charge in the first 30 days after sale.

Wasted advice I'm afraid Steve. Swansea has not been back to the forum since posting his question.
