    Hi everyone, I recently tried to start my car after having sat for three weeks to which it started but stalled out almost immediately. The car has never missed a beat up until this moment, it is serviced regularly and has just under 90k kilometers on the clock. After consulting roadside...

    I turn my 2001 325i idles at 750 slowly dropping as it warms up has a rattle that I think is the exhaust lifted the car up and it is welded and hanging and mangled. Muffler bounces hella.Once it gets down to 500 rpm not fully warmed up yet the rpm goes down kinda hesitating and sometimes it does...

    hallo guys I'm using an e46 325i with a zf5hp19 transmission. I just replaced all the seals and clutch matic using original ZF parts. I also replaced my speed output sensor with the original zf part. I feel if I use the transmission in the "D" position when I stop suddenly the shift from 2...

    I have a m54b25 engine which burns oil and smokes occasionally. After a fresh oil change and about 100miles in and the yellow oil light comes on the dash. I recently put forte oil fortifier and forte valve stem seal conditioner which are oil additives. Now I put over 150miles on the car and the...

    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...

    Hi all, I have an 04 325i 5mt touring. Since it's getting colder in the Netherlands I've been hearing this strange rattle on cold starts. the engine only does this the first second while it's cold. I had the Vanos unit revised about 2 months ago. so that shouldn't be the problem. the engine...

    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...

    Hey I’m new here but I was wondering what would be a good camshaft upgrade for my m54b25 would be. I’ve been doing some research and I seen somebody replace the intake cam with a 3.0 cam. I’m wondering if this is a good option or if I should do something else?

    Hey guys. New to the forum, not new to BMW's. I have a 320i Touring with the 2.2L motor. I have the opportunity to grab the full intake off of a 325ci. So I'm wondering if there are any sizes differences in the 2 manifolds and/or throttle bodies? If there are, i'm definitely not expecting...

    Now in most circumstances I'd just buy a 330i. However my 325i has a cracked block and I don't have the money to buy a whole new BMW, so I found a guy who's giving me a smoking good deal on a 330i M54B30. He's selling the whole car for 1500. The car was written off buy insurance after some one...

    I have a blown m54b30 in my 330ci Vert. I found a M54b25 to buy. Can i just swap it in there? I have searched far and wide for a thread like this, didn't find anything.. Everyone wants to go from 2.5L to 3.0L , but i never saw anything about going the opposite direction. Any thoughts?

    I'm not super familiar with working on AC systems but I get the basic gist of how they work. What will happen if I disconnect the heat insulated line that runs down the right side of the engine bay by the exhaust manifold? Catastrophic explosion? Freon release? End of the world? D: I need to...
