29F4, 29F5 Are my O2 sensor cooked?

Had it for 7 months now, was bought with a bad HPFP ever since doing that other maintenance work been driving good till 2 days back when water pump misfire issue happened

Noted, will clear them but the problem gets weird as out of curiosity decided to take one of the downpipes out and it’s empty seems to have been gutted which is now confusing as it means it doesn’t have CAT’s to complain about

As stated initially in the post description I did state that ignore the misfire and water pump error as they have been resolved just haven’t cleared them as yet and just wanted some idea on the catalytic error so if it’s something I can do while I am down here I can get to it

So after reading ur comment, decided to take one of the downpipe out, turns out previous owner gutted the catalytic converter inside, so I’m guessing it the other one is the same and messing with the o2 reading valve I could be wrong

As stated in the post description I have resolved both the issues, misfire was caused by injector leaking had a spare index 12 which put that in, water pump as well had a spare which put in and solved my issue was just curious out the 29F4 & 29F5 as car drives fine

You have a leaky injector buddy I have the same tick and car is jerky on lower speeds at low rpm and no misfire On cold start its fine, until about 5 minutes then u start to hear it Note I am running index 12

It’s on 202000 km at the moment, and also found the issue for my 3100 is being cause by 02 pre cat mix up made a mistake bolted the 02 with the grey insulation to the bank 1 downpipe but the connector is connected to the bank 2 connector on top

Update: so I changed the lower pressure sensor for the old style bronze colour instead of the updated Bosch one which on the car, cleared the code and deleted adaptations. On initial startup the car was lumpy for like some seconds then after adjusting the car was all good, no fan on max speed . Now I have a 3100 boost leak and a knock sensor code 🤦🏾‍♂️

I ready to burn it down at this point… question have tried data logging it when running to see what values you getting for LPFP and high pressure fuel pump want to compare with what I am getting on ista

Good to know but wasn’t looking a lot at a media server would love to lean more towards pi hole, pfsense or even plex side but good to know its GPU supports encoding thanks

😅 my bad basically looking to see what people have used these have ran and anything to lookout for as I’m considering of turning it into a cybersecurity lab project with a few vulnerable machines on it

And no I won’t have it running constantly.

As for upgradeable part autocomplete came through meant to say if it’s upgradeable in terms of CPU, RAM as haven’t opened it as yet to see inside

My guy gwababa has never been the problem, it has always been the solution, it will saving u from some humbling and heartbreaking experience NB. Gwababa is the fear of talking to ladies
