BMW SULEV

Been searching BMW 3 Series online and noticed SULEVs popping up more often.

Initial googles say expensive repairs, e.g. fuel pump is integral to fuel tank... like $7K to replace if fuel pump bites it. Blah, blah... BMW extended warranty on fuel system.

Also, claims of lower power output vs non-SULEV, I dunno. Didn't google that deep. GRM has the answers. Whattya got?

TIA

Had to Google it myself. Had never heard of it before. I can't help,but thanks for the interesting car knowledge.

SULEV only means that it's just really low emissions, and an on-board diagnostic that matches it.

Early SULEV cars do have some special hardware- but that would be limited to the 2002-2005 era, generally. Now making PZEV (which is SULEV with really low evap emissions) is more about an expensive catalyst.

The more complex cats might lead to lower power, but the later the car is, the less likely that it would matter.

If you care, SUELV is 0.010 g/mi Non-Methane Organic Gasses, 0.020 g/mi NOx, and I think it's 1.0 g/mi CO (but that's never the issue) run on an FTP75 test, and the car is capable of that at 150,000 miles.

I can't answer any BMW specific questions, but have been working PZEV/SULEV since 2002.

i cant seem to find the choke adjustment on the Carter AFB on my ford f-100...any insight? and what do you do when the diaphragm in the vacuum advance fails?

Makes me chuckle.

The only time I've ever touched a carburator while at work was when a guy I sat next to gave me a perfectly new Carter 1 barrel for my '77 F100 truck. Why he still had it was beyond me- as it was 1993.
