Reset the DTC and see if it reappears.
My 1992 525i e34, US version M50 non-vanos engine have check engine light permanently while driving. The error code on its OBC is 1221 which is oxygen sensor. But this version is without O2 sensor and catalyst from the factory. What are the possibilities to have this error code and check engine light.

a 1992 E34 US version without oxy sensor and without cat?
let me know the VIN and I will check that out.
So far I have only seen U.K. and Italian spec cars without cat, as that was an option in these countries in these days, but USA in 1992?
I thought almost all gasoline cars in USA were equipped with cats since around 1975?
VIN- BF97758, in realoem there is O2 sensor and cat, but actually no. The entire exhaust system of the car is all original.

Nothing mentioned in the VIN decoder that the car came without cat originally ex factory. Normally in case of U.K. cars that is mentioned.

My Feb '92 525i M50 NV went to the breaker's a short time ago so feel free to use the VIN: GA11907. That certainly left the factory without a cat/O2 sensor and unlike yours, you can see they are not listed in realoem. I dont think ZA bothered with emissions until about 2005 :-) BMW probably used the same ECU with software differences for with/without CAT.

That was assembled in ZA. Not much data available in VIN decoder

Yes, I contacted BMW ZA but they couldnt provide any more information than what you posted. It is a little poor when they didnt even record the colour of the car :-) The VIN plate said it was an AHL. BMW ZA had to contact Germany about that and confirmed it was similar to what the UK calls 'SE'. I have only seen HL it applied to a 6 series! Anyway, getting a bit OT.
Has the car had an ECU change or electrical issue recently?

If its a US version then it definitely had a o2 sensor and a cat in 1992
I had a UK import 525i without cat and o2 sensor. This is how it was listed on a vin decoder. I believe that your car would have left the factory with the cat and o2 sensor.
I actually added the cat and sensor to this car and it ran so much better. I took the front exhaust section from a wrecked car, so it was a straight bolt on and plug in job.
