Mein Auto: 02 BMW 525i M54 auto 130K
Today, Ågent99 had to replace his DISA valve because he failed California smog with lean error codes. So I added his before & after results (he lives right next to me so our numbers & environmental part of the test on the dyno should be similar).
- System Too Lean Error Codes and Others

Here's the combined E39 smog data so far
(Note all California tests are with the rear wheels on a dynomometer):
--------------------------------------
- Northern California (bluebee), 2002 525i, 87 AKI (just after rebuilding the ABS control module)
- Northern California (bluebee), 2002 525i, 91 AKI (after clearing P0500 code & driving for two weeks)
- Northern California (Ågent99), unknown E39 (before and after replacing DISA valve which caused failed smog tests)
- Southern California (Gian), 2002 530i
- Southern California (bugratu), 1997 528i
- Southern California (bugratu), 1997 528i (after adding CRC "Guaranteed to Pass Smog Test", plugs, engine air filter)
- Southern California (+moulin), 2002 530i 5-spd 105K
- Canada (bmw_n00b13), 1999, 528iA
- UK (dunk1127), year? 540i

Note: This list will be updated with new data for as long as the forum will allow us.


It's interesting the effect the new DISA had on Ågent99's results:
- Hydrocarbons went down by more than a quarter!
- Carbon monoxide went down (for the most part)
- Nitrogen oxides went up (way up) by something like 500%
- C02 & oxygen remain unchanged
