WHAT DOES SULEV MEAN REGARDING BMW'S 3 SERIES SEDANS?
super ultra low emissions vehicle.
Also means it has a special engine (M56) with more expensive parts. E.g. the PCV valve is built into the valve cover. So to replace it, I was quoted $1500. The fuel pump is integral to the gas tank. The tank must be replaced if the fuel pump goes out. Look it (M56) up on line. If considering buying one, especially an older one look for the non-SULEV engine.
The original question was about the 2012 3-series BMW, which doesn't have an M56 engine. The 2.5L M56 ended in 2005. Since then, the 3- series SULEV engine has been the N51 3.0L, which has just a few parts different from the standard N52 but the same torque and HP and doesn't have the fuel pump and PCV valve repair costs of the M56.
I just ordered a 328xi and they ordered it this sulev. Is that bad ? Should i ask for a change ? Does it change preformance im leasing so repairs are all covered for 4 years so no repair cost issue just worried about pep preformace etc
The sulev feels more like a regularly asperated engine than the non- sulev. I had a 2013 non-suluv and when it was totaled I replaced it (unknowingly) with a sulev (which was also a South Africa build- which I also didn't know). I much preferred the non-sulev. Under full throttle the non-sulev feels like it rev's easier and I could feel the turbo kick in... not so with the sulev. Also the sulev takes premium gas and the non-sulev regular
