    Hello! I have recently come up on a 2005 325Ci with an M56 SULEV , unfortunately, it is not in driving condition (input shaft seal and bushing broke, getting it fixed, slow transmission shop, blah blah blah...). Anyways, on the more exciting hand, I am looking at the road ahead. In this case...

    Hey everyone! My E46 325i just crossed 200k miles a few weeks ago (Yay! I made it), but with that milestone has now come some very strange electrical issues that are making my head spin. The predominant issue I'm facing is what seems to be the alternator not producing enough current to run the...

    Hello Fanatics, I have recently purchased a 2005 325 ci SULEV with out keys and thought I could make it work by just switching out the DME/EWS with new key but fell short because of not knowing the difference between an m54 and m56 engine. Long story short purchased a 325i DME MS45.1 (PL06671)...

    Hello, I recently saw a comment on here for people who have put an m54 gas tank into an m56 SULEV. When this swap is done- the m56 gas gauge in the cluster will never reach the “full” level. The comment mentioned the ability to change the instrument cluster somewhere in the INPA menu to the...

    Looking for the fuel relay for 2003 BMW 325i (M56) Sulev model. I've checked the forums, pulled the glove box and only see 3 relays where there should be 4. Was the fuel pump relay moved somewhere else because it's a SULEV? Any help would be great. Thanks.

    Hey guys, I’ve been around e46’s for a long time and have always loved them but I’ve owned an e90. I just took a leap and bought a 2004 325CI sulev today for a really great price. The only catch is that it needs a transmission as the previous was taken out by a shop and never put back in. So my...

    I have a 2003 325I with the M56 engine, it was basically given to me so of course I know there's some problems. It was running and driving fine when I first got it, but the radiator was cracked so I didn't get much driving in either. I just put a brand new radiator in it the other day and it's...

    Over the past six months I have been going through the process of building a 2004 330ci to OEM+ specs. I started with a dirt cheap M56 325ci with a bad motor, and went from there. A lot the the information I had to figure out or find for myself, and thought that I would share what I've learned...

    I've searched and read many posts and have gotten a ton of information but I'm still lost on certain specifics. For starters, I have a clean title 03 325i sulev with 216k miles. Reverse is out with a ZF tranny and motor is garbage. Interior and body are perfect. The other car is a 325i 03 m54...

    I'm just finishing up my 04 coupe project and I'm having a transmission/TCM issue hopefully someone can help me out with. The car is an 04 sulev M56 car. I bought it with a bad engine (no compression on #5). It ran rough but was able to drive on the trailer and around the driveway. No...

    Hi Guys! Long time member here. Recently completed a full m56 Valve cover swap - including PCV delete. I'm now getting a large amount of positive pressure through the crankcase which is leading to oil leaks around the engine. When removing the Oil fill cap I get the sound of air pushing out...
  14. DIY: Do It Yourself
    Ok so I'm looking to hear if anyone has any info. The M56 SULEV engine has a hydrocarbon filter built into the air box as a part of the emissions system. This to me says "restriction" removing it would be simple enough however would mean you can not replace it in the future if needed. The one in...

    Hey there guys I'm pretty new to forums but i haven't seen a thread that speaks on risks for installing an e46 330 intake to a e46 325 m56 engine. Is that okay or am I hopeless having a m56..? If there are no risks Im considering installing the AFE .. or K&N..with a dry filter

    In this first post, I am including any important information I find for SULEV owners, regarding warranty, part compatibility, etc. The Air Resource Board approvals indicate a service life of exhaust and evaporative emissions components as being 150,000 miles. I'm just curious how many M56B25...

    This weekend I decided to change my spark plugs so I looked over the DIY and found some great instructions and thank you for posting that. However, I have a M56 engine and I believe that the last (6th) spark plug if farther back in the engine bay than a M54 engine. My question is, how in the...
