Different types of lamba sensor for 97/98 cars?

[Trevor /chedder]

Hi all
what do you think of this article about titania lamba sensor for the 97/98.
The one I fitted seems to be for any m44.
Do you think this could be part of my high emissions problem?
Thanks

BMW Z3 - O2 Sensors - Get the Right Ones

Describes how BMW used 2 different types of O2 sensors on various year Z3's. When you replace sensors, you must get the correct type, based on VIN.

My understanding is that the titania O2 sensors were only used on some M52B28 Z3 engines.

They run on a 0 to 5V system whereas normal Narrow Band O2 sensors run on a 0 to 1V system. Plus the rich/lean settings are the other way around.

The chances of you having titania on a M44 would be low.

Thanks NZ, my emissions reduction continues!
