Hello guys... I have the following codes from inpa, and would like to sort these once and for all...
2724 CDKLSH2 Oxygen sensor2 after cat
2727 CDKLASH2 Lambda sensor ageing after cat bank 2
I have done some research on this and it seems the N42 has 5 sensors, 3 regulating and 2 monitoring. Question is, which sensors are the codes referring to? To me "after cat" could be relating to after the two manifold cats, or after the last cat. Parts drawing is below, any help is much appreciated. Thanks.
