have you run it with maf unplugged? brittle things mafs, new ones have been known to be broken
also second code suggests running rich... either lambda fault or boost leak somewhere, id be betting on a boost leak. have you checked all the boost and vac hoses for splits, especially the ones under inlet manny? any acces to vagcom for logging?

one under manny has been replaces, the smell of fuel i thought it might be lambda, do they have 1 or 2 and not sure which one i would have to change,
no not run it with it unplugged, |

2 sensors, one pre cat one post cat... code suggests bank 1 too rich which is the first sensor afaicr..
id unplug the maf nev and see if it runs better first. could do with some fuelling logs to check lambda, or at least voltage test to see if its working. is there an eml?

try the maf unplugged first nev, if not then id look for boost/vac leaks, mybe get it pressure tested before looking at lambda (costly).
Vagcom logs are the crucial part here tbh
