Lambda sonda for audi s2 aby

[valjo]

hi!
well i will change lamda sonda in mine audi s2 aby.
According to akte there is 2 different lambda sondes for audi aby:
-034906265f-for cars with cats
-053906265-for cars without cats

now i am a bit confused becaus according to mine konwledge all s2 aby have cats original.
The questation is whitch one should i bought because my car has original cats but i removed them?

any ideas?
thanks

S2's exported to countries like south africa (ZA code in family album) had no CAT as they didn't have unleaded petrol at the time.

Its a good question on which is best lambda probe... It may be that the 'without CAT' option assumes use of leaded petrol. I honestly dunno.

Personally I'd replace like for like so you'll need to get the part number off the lambda on the car, although that might have already been replaced! Not very helpful, sorry
