TomsFocus Posted November 27, 2022 Share Posted November 27, 2022 Still the same problem as before, you have the wrong cat fitted. 2 Quote Link to comment Share on other sites More sharing options...

Seriously though, it can take months or even years before faults show up. Same happens with DPF deletes and EGR removal on some engines. They work fine for a while, but then the ECU seems to suddenly realise somethings wrong and start throwing faults months or years down the line. 1 Quote Link to comment Share on other sites More sharing options...
unofix Posted November 27, 2022 Share Posted November 27, 2022 I'm a bit puzzled by the fact you say it is Bank 2 on a straight 4 cylinder engine. 🤔 Quote Link to comment Share on other sites More sharing options...

His vehicle should have 2 cats in parallel therefore bank1 sensor 1 and sensor 2 is one side and bank2 sensor 1 and 2 the other side. 1 Quote Link to comment Share on other sites More sharing options...

steplce74 Posted November 28, 2022 Author Share Posted November 28, 2022 been quoted £500 for a new cat plus the cost of 2 more lamba sensors so about £700, no guantee of stopping the engine light going out due to all the electric problems i have had so far, Quote Link to comment Share on other sites More sharing options...
