I guess when you buy a car it might be a good idea to ask, "what's the most expensive part to replace" and it's a $7k fuel pump - run.
There has to be some way to retrofit the plastic gas tank and add the fuel filter plus fuel pump to the M56 SULEV. That would be the route I would take if mine went out.

I have Dinan Stage II programming, a Gruppe M intake, and Dinan exhaust....no codes here. Really interested in if a fuel system conversion would be possible. For token pic, inserted is a shot of my engine. The Dinan stage II programming did not have any issues or any of my mods with a check engine light.



I do believe a retrofit can be done to the M56 fuel system. When my radiator went, I had it replaced with a NON SULEV radiator. You have no idea how much they want for the SULEV catalyst coated radiator. They actually have different part numbers.

just a quick fyi the fuel tank/pump/filter/sending unit assembly is low mileage about $1500 from a dismantler. called a reputable one today and he knew exactly what i was talking about and says they almost always have them in stock

i would presume that is cheaper than retrofitting the entire fuel system

Here is a great link on the SULEV
http://www.ge39.com/files/M56sulev.pdf

It is actually a pretty phenomenal car to be honest, a lot of the components seem to be of higher quality over the M54.

My Ride: BMW 2004 325 Ci
I've got a 2004 BMW M56 SULEV with 41K miles - Fremont BMW just told me that the secondary vacuum line and hose need replacing and the DME reprogramed. They want $895 to do the work but my independent mechanic said it was covered under the extended emissions control warranty and BMW should replace it for free. Any comments?

technically that tampering with federal emissions and is a fine..... Not that I wouldn't do the same but........

The TSB posted states:

"The emission relevant components are warranted for 15 years or 150,000 miles."

The specialized stainless fuel tank assembly seems to be included in that.

My biggest concern is that my CPO warranty is about to run out, and I'm at that uncomfortable decision point of whether or not to get an extended, 3rd-party warranty. I was leaning TOWARDS doing so b/c of the high cost of M56 components failure. But if there's a special 15/150,000 warranty on our precious SULEV systems, I'd really like to know.

Anyone find the link?

Happy to find this thread. We M56'ers have to stick together.

~Update~ Here's the TSB: http://www.ge39.com/files/M56sulev.pdf

But the question remains... What exactly is covered by the 15 year warranty?

05 sulev w/ 67k miles here

anyone know any fuel filter/pump starting to go bad symptons? other than of course no start. I've been having hard starts lately w/ my car, suspected it was a dirty fuel filter. I had battery replaced and spark plugs changed back around 50k miles. possible starter problem?

unfortunately that sounds painfully like the fuel system (pump/filter) upon initial thought. fortunately, although a hassle, it will be free for you.
