I looked at my spreadsheet. I didn't write down the specific code. I do remember it saying insufficient flow. The pump was screeching when it was about to fail. It set the insufficient flow code. I tried the SKP and URO from RockAuto. Both were returned for a HELLA*728124190. $202.79 I don't see it offered on their website. The part number is now listed at PIERBURG.

I have a Foxwell 520 Pro with BMW software. I can activate all components on my X5. I like to use for fan activation and smog pump testing. It's good to test if switches or a motor have failed.

If you return the part, mention why. I stated the first two set insufficient air flow codes. I had no trouble returning them. Plus, I ordered the next expensive one.
