bmw lsu4.9 problem

[r.hellenbrand]

Dear,

I noticed a problem on BMW lsu4.9 sensors.

The sensor is working, but I notice a lot of noise on the lambda signal.
If I look in the raw values, I do also see this noise.

I connected a VW lsu4.2 sensor, and voltage is stable (changed back to lsu4.2 in sensor type)!

Is this a known M800 problem, and is there a cure?

I run the latest software version!

I hope someone can help me out!!!!!

Thanks,
Ron

Ive had difficulty doing air calibrations on some 4.9`s. The calibration number would be very unstable and would sometimes run into negative numbers. Only some do this.
