the car is a 2015 F20 bmw 118d.

i did a Carly health check as a i recently bought the car .

it came up with the following codes in the engine section

Fault code: 284E00 Lambda probe according kat, nernst voltage signal: interruption
Fault code: 283400 Lambda probe according kat, controlling heating: interruption
Fault code: 282E00 Lambda probe after catalyst, triggering heating: short circuit to positive.

there are no warning lights ,car does not misfire and drives well


i have erased these codes and Fault code: 284E00 Lambda probe according kat, nernst voltage signal: interruption has come back after few days,

any idea what this means?

i think the post catalytic 02 sensor is somewhere underneath the DPF and i could not see it from the engine bay.

just foudnd this answer from another forum--"You’d be surprised how many of these cars have this fault and it makes no difference to the day to day running.Usual pick them at at end of warranty checks with no complaint from the owner.After cat sensor will be faulty.Its under the car right next to the DPF flexi joint.Condensation forms in them with lack of use and this shorts out the heater element.
