02 sensor problems!
Posted: Tue Dec 05, 2023 6:48 pm
Hi guys,
So I have recently replaced my whole exhuast from the downpipe back on my 2014 1.4 polo (CGGB). The Downstream sensor was seized so I replaced it with an NTK sensor (which I heard was the best without paying dealership prices for OEM part). Cleared the codes and after a few cycles bank 1 sensor 1 codes start showing so I assumed it was aged and had to also be replaced. So I did the same with an NTK one.
Cleared the codes and after a few cycles it’s throwing codes for both. I can get specific code numbers if needed.
Any help would be appreciated, it’s been a real pain! Hoping a don’t need to pay the £300-£500 for genuine parts.
Cheers.
