engine management light - lamba censor

[maz172cup]

been driving my car for 600 miles after rebuild with engine management light on, they said they will sort it out when I return for 1st service.

Went back on saturday, they took the light off and driving home the light when back on, they said it means you need to change lamba censor.

clios have two censors, he didnt even tell me which one i need to replace.

I wanna this is problem sorted before it damages the Cat.

can someone advise me what to do?
