    Hi All! Hoping there's someone who might be able to help me diagnose a new engine noise that has sprouted, I'm having difficulty locating the source. Happened shortly after an oil top-up. Can't hear it at idle and disappears from around 3500-4000rpm This is from a 2004 E46 330ci Convertible...

    Hi again! After swapping an M54 into my N42 2003 Touring with a blown engine, i've just managed to get it driving for the first time. At first, the power steering worked, but after ~5 minutes it suddenly seemed like it was completely gone. After shutting the car down and starting it again a...

    Hi Fanatics, I am in the UK and in line with government policies, E10 fuel has arrived and is now the standard unleaded fuel replacing E5. Having checked on the government website, it says all BMWs are fine to run on the new E10 fuel. So I've just wanted to ask if anyone has run on the new E10...

    My e46 320ci with the m54 engine has had this problem awhile where the idle is kinda bouncing and if i rev the engine it will stall when "coming" down to idle again. It stalls very easily when trying to "take off", the idle is better if AC is turned off. Replaced CCV including O2 pilot mod...

    Hello! I am having an awful time trying to get my 2000 BMW 323ci manual in which I have swapped in a m54b25 running. I have taken the dme from the 325 which the engine came from and have had it reprogrammed with an ews bypass. The drive by wire accelerator pedal I have also wired up to the DME...

    Hello, So I drive a 330ci approx. 145k and of late have noticed a strange ticking coming from the engine bay while driving. The noise comes and goes with various levels of volume. It sometimes does come right away when starting the vehicle but usually comes after driving for a minute or two. I...

    I recently did a turbo install on my 2004 325ci, m54, SMG, ms45.1 and I have run into the problem of knocking or loud pinging when at idle or cold, in addition to a very rough idle. Parts installed listed below. 35mm Bov Universal aluminum intercooler and 2.5inch piping. AEM boost gauge Oil...

    Hi, PLEASE HELP!! I have a 2001 330i. About a month and a half ago the car was idling rough, running lean, misfiring, super down on power and appeared to be in limp mode. I found the issue to be a bunch of torn inlet pipes and a faulty MAF sensor. I replaced all of these, scanned with the scan...

    Alright, I recently switched over to the dark side and picked myself up an 04’ 325i (with manual trans) for cheap and I’ve been fairly happy so far, just trying to patch up the oil and coolant seeping from every orafice. But after driving for a week I’ve found myself looking for a little more...

    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...

    Hi just wanted to get some opinions on what I’m gonna do to my e46. I’m getting a burble tune and catless headers. Now of course that’s gonna be loud already but I want loud so I’m gonna delete the muffler with a cherry bomb glass pack muffler which will give it a nicer sound. But do you think i...

    Hi guys, bit of a back story, for my 18th birthday I was given an MOT Failure 320ci which has sat at my local garage for nearly two years. it failed on the exhaust cam sensor throwing the emissions off, which I've changed and the code has cleared. However, it has a misfire on cylinder two and a...

    So I'm going to check out an '03 325i wagon in the next couple days which is a car I've had my eye on for a while (I'm glad I was able to find this community first!). I was just wondering if you guys had some tips for what to look for and what to watch out for before buying. In addition, the...

    Hello. I have a problem with my e46 320ci. The car wont idle and it feels like it doesnt have any power at all. It also runs very rough when i press the throttle and the rpms jumps up and down. I diagnosed the car with an OBD scanner and it said it was a bad mass air flow sensor so i changed it...

    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...

    Hey, does anyone have a euro2 flash file that has the EWS disabled for an M54B25? Can't find anything online that would help me combine the two. I've tried flashing euro2 and changing the hex values to the 512 file according to Siemens MS43 Immo Off Guide [430037, 430056, 430066, 430069] , but...

    Hello, on my 2003 325i touring I have recently changed original power steering pump because of it’s broken driving shaft. I’ve replaced it with new aftermarket one and turned the wheel back and forth to get system rid of the air, however the steering still feels heavy once at idle and when...

    First post here - wanting to say hello and thanks to everybody for such an awesome site and community. As the title states, I'm looking to hear anybody's thoughts on the possibility/feasibility of swapping engines from my 325xi with a M54 with an N55 out of a 535i. A bit of backstory:my...
