I have a '95 M3 with an Euro S50b32 swapped. Using a Foxwell scanner I'm getting the following codes, but cannot find out what they mean:
8a DTC -DME: DMS Digital Motor Electronic: fault stored
2a DTC -DME: DMS Digital Motor Electronic: fault stored
42 DTC -DME: DMS Digital Motor Electronic: fault stored
35 DTC -DME: DMS Digital Motor Electronic: fault stored
12 Instrument Cluster code 20 DTC Ignition Key Contact Operation not plausable
The car fires up and idles just fine, but during moderate acceleration I can hear a "wha, wha, wha" as the engine revs. I hope that understanding what those codes means, I can chase down what is causing that noise.
Thanks for your help!

S50B32 is an engine found in european spec cars, which usually have a 20pin round BMW connector in the engine bay. If your car has such a connector then get a cable and the software to read codes through that, it will give a more detailed code description.

I have the Schwaben by Foxwell BMW/MINI Scanner 14020SCH with the 20 pin adapter and those are the codes that showed up. I am struggling to find any resource or software to interpret what those codes mean.

If nobody can tell you what the codes mean and you can't find it using google, then I don't see another option besides trying INPA and hoping it can give you more information.
Also, INPA can provide more engine data and values that could help diagnose your problem.

I think you should use INPA, software is free in the z3 diagnostics forum. Get the cable off eBay or Amazon.

Click the search button, select "search single content type", select the "e36 sub forum" specifically, try the "search titles" then try the "search entire posts".

Google showed the following:
8a code was related to body control module
2a code was a speed sensor
42 and 35 were related to the dsc stability system.
Not sure how accurate these are, take it with a grain of salt.

Do you feel a hesitation during acceleration or is it just a noise? Was the vanos ever rebuilt?

The VANOS seals were replaced 10k miles ago. There is a slight hesitation during acceleration when that noise is present and then the noise disappears when holding a constant speed.
I appreciate everyone's comments and helps as I chase this issue down.

I have nothing to add but am curious what sort of mileage is on the engine.
