UK-POLOS.NET - THE VW Polo Forum

Hi all, newbie here. Trying to help out a non-technical friend with his beloved, stock 2016 Polo 1.4GT. At 60.000 miles, it's occasionally stalling from idle, getting worse, and I offered him to read out the error codes. I got an astonishing 66 of them falling in 3 categories: O2 sensor, Boost control pressure sensor, and assorted camshaft/timing codes. All listed below. Does this sound familiar to anyone?

Should one suspect low battery voltage or similar as the culprit for such a vast array of codes (including several "circuit failures")?

Any ideas welcome!

Thanks, Mike
