cupra r fault codes. help :(

[kieran969]

hi guys, i have a lcr 225 with a decat and full cobra, im getting 4 fault codes and im not sure if there due to me decat or the sensors are faulty

does a decat show up codes for both lambda sensors or just the one after?

the codes i have are :

17526- oxygen lambda sensor heating: B1 S2: open circuit: P1118

17524- oxygen lambda sensor heating: B1 S1: open circuit: P1116

17511: oxygen lambda sensor heating: B1 S1: performance too low: P1103

17522- oxygen lambda sensor B1 S2: internal resistance too high: P1114



are these all because of the decat or is the sensors faulty and does anyone have part numbers?

thanks

Lambda or oxygen sensors as they sometimes known, you got emissions light on? Using more fuel than normal?
