M56 SULEV fuel filter replacement question

Curious,
I have 62K on the car now. I know from the Bentley manual, the fuel filter is built into the tank. I assume I would have to drop the gas tank to get to the filter. Has anyone had theirs replaced on a M56 engine? Wondering what amount of $$$$ damage is charged to do this. Also, has anyone with a M56 had engine programming done? From what I have searched from the forum, Dinan programming will not work on a M56 SULEV. Will a shark programmer work with the M56? Thanks all. There is not much info here on this engine so I take what I can when I can get it.

The fuel filter is indeed built into the tank, and it's supposed to be a lifetime fuel filter. Doesn't need replacing.

Exactly. Replacing the fuel filter on an M56 means replacing the whole fuel tank...

That is good and bad news....good news is a lifetime filter, bad news...I do not believe in lifetime auto parts. Anyone had a issue with the M56 fuel filter going out early? Thanks for the posters above, makes me feel a bit at ease....I know from the Bentley manual there are a few differences from the M54:

325ia (sedan, coupe and sport wagon) models sold in California, New York, and Massachusetts as of model year 2003 and in Vermont as of model year 2004 use an updated 2.5 liter engine designated M56B25 SULEV (Super Ultra Low Emissions Vehicle) to meet the stricter emission requirements.

The M56 SULEV uses Siemens MS 45.1 engine management and includes many emission control system changes. The emission relevant components are warranted for 15 years or 150,000 miles. M56 B25 engine power output and performance is the same as the comparable models with the M54 B25 engine.

M56 equipped vehicles meet SULEV tailpipe emission standards, which are approxamately 1/5 of the previous ULEV standards. The vehicle also conforms to Partial Zero Evaporative Emissions requirements (PZEV).

Notable modifications to the M56 SULEV engine include:

. Additional carbon filter in the air filter housing and closed throttle valve actuator for hydorcarbon blocking.

. Metal fuel system components constructed of stainless steel and fastened together using permanent couplings. Stainless steel components include fuel rail, injectors, tank ventilation valve, fuel tank, tank filler neck, and evaporative canister. The fuel pump sealed inside the tank and is not serviceable.

. Crankcase ventilation valve in the aluminum cylinder head cover.

. Wide band precatalyst oxygen sensors.

. Pistons with 3 mm wide ring lands.

. VANOS set to fixed position during start up.

. New style fuel injectors with 4 hole design.

. External heat exchange surfaces of the radiator coated with catalyst to reduce ozone in air drawn through radiator.

. Secondary mass air flow sensor for improved monitoring of secondary air flow.


ABOVE INFO POSTED FOR OTHER M56 OWNERS INFO, not much info on the site about it so do what I can. I can verify it has the 330 muffler with the butterfly. Not sure on the 330 throttle body as I have no size to compare. I can say it is over 3 inch dia when installing my open air filter, about 3 1/2 if I remember.

I like the fact the fuel system seems heavy duty...but secondary smog pump seems to be an issue, as well as SES lights for the smog system. Any way I can mod this system to take advantage of the injectors, exhaust, and throttle body? Seems like Dinan programming will not work from second hand info on the board. Siemens MS 45.1 engine management, has it been cracked?

Again, thanks for the info on the M56. I learn as I go and post what I know. With so many Cali guys on the board....some of them have to chime in with info on this engine and mod capabilities. MODS, if you could take the M56 info and make a stickey on it, would be appreciated.

Not sure about SULEV, but my 2004 325CI has MS45.1, ESS managed to update the software when I installed the TS. It seems only US spec 325s post facelift has 45.1 whereas all other spec cars has MS43.

Also note the alternator controlled by MS 45.1 has cylinderal plug similar to Z4 parts whereas the normal MS43 cars has square plug. When you need to find replacement for the regulator it will be come PITA to find! If any one has the correct P/N for this regular, please chime in. thanks!
