O2 graph looks pretty good.
You really need a MAF based upon the Gram per Second values you are reading. I had my 1.8T VW out today and it even was getting up to 70+ Grams per Second when I jumped on it a bit, not wide out.
I was still using my Launch Creader VI for this.
Suggest a source like ECS, BimmerZone, AutoHausAZ, BMA Parts, possibly even Amazon.
I will try to see what my 2006 E46 330cic looks like if I can get any info without removing it.
Since it is not original, I would think it is a counterfeit or wrong application??
I put the Siemens number you had on Google and almost everything came up Ebay and had China associated with it.
DO NOT BUY ON EBAY.
Replace your MAF, you will be likely have a good running engine.
