I had the same fluctuating boost problem last week...

I did a search and found the advice to clean the BPC. I used brake cleaner to avoid residue. Afterward, the boost was much better, with only a hint of fluctuating. I assume it is because the valve is bad, and even though the cleaning helped, the fix will be short lived. Only thing I missed is disconnecting the ECU, and doing the adaptation run, which I will do tomorrow.
Based on the above, I now think I need a new BPC valve. Do I just shop for the cheapest one, or is there a difference in these things?
