03 325i low idle

The car seems to have a low idle when the I put it in drive. I have cleaned the ICV, throttle body and rebuilt the disa valve. The idle is around 650 with it in drive and Im not getting any CEL or EML lights. I wish it was about 700 to 725.

if i remember correctly from my previous 325Ci, it was normal idling at 650RPM when in D
to be on the safe side, get it scanned for codes

Why? Normal idle is about 550. That's where my 325 sits in D and its dead smooth.

I think that you'll find that while the tachometer on the dash says about 550, your actual engine RPM is around 700+, if you check it with a scan tool. That's the case for mine anyway.
