    Hey first time posting on this thread but i am kind of at a loss of what i should do at this point. I have a 2004 325xi. Vehicle will only start about 1 in every 5-6 cranks. I can hear the fuel pump cycling. If i let it sit for 10 min, the fuel pump cycles about 10 times with just the key on...

    Couldn't find any older posts like this so here we go. I knew that my battery wasn't great and a few days ago I accidentally (stupidly) left a door open for around 40 minutes causing the battery do die. Brand new battery in, cranks just like when it was working but no signs of starting...

    Hi everyone, I have a 2000/2001 325i auto, UK spec. A couple of weeks ago I started suffering intermittent "no crank" issues, and diagnoses pointed to the EWS. I'll try to keep this post brief, but please let me know if I should provide more information. I would really appreciate your advice...

    Recently decided to change the CCV system on my E46 330i since I live in a cold climate and it seemed lika a fun project. It has turned into a not so fun project, since the car no longer starts after the intake was off, CCV changed and everything put back together. When we were done, I sat down...

    Hi guys, this one has me stumped, very confused as to why this is happening. have had poor fuel economy recently and due to increasing fuel comets here in the UK (and elsewhere!) I decided to replace my MAF as I had code for bad MAF. I have just done this no problems. Brand was BOSCH. went to...

    Hey guys, I have a 2001 325I, recently I changed the spark plugs and the entire machine stopped turning on. No crank; no start; no noises. Ive replaced the starter, fuel pump, coil packs, and battery. Everything turns on and all lights show up, but my temperature gauge shoots up to the middle...

    Replaced motor mounts today along with swapping catless headers back to the oem headers. Also changed the ecu from a pop and bang tune back to stock. Battery was dead so tried to jump start and it would crank but nothing else. At first I thought I forgot a connection on the ecu but evrrything...

    I recently bought an 03 325xi from a friend of mine. He had the key taped up. The buttons didn't work and upon peeling off all the tape I found out the battery was missing (the original terminals were still soldered to the board). I watched the battery replacement procedure and didn't seem any...

    Hey E46ers, My '03 325Ci is giving me some trouble. Won't crank or start. Would start after a few tries before, but now nothing. I've done a ton of troubleshooting with ISTA and no go. I've got an "80 - EWS transmission/parity" code among others pictured. From what I understand, the problem...
  11. E46 XI
    So the other day I was i driving and noticed my battery light, abs, brake light, and the other one came on and shortly after that the gear with the exclamation point inside appeared. I pulled over and examined shit and disconnected my stereo system. The car fired right up. I drive up the...

    Today I changed my Crankshaft Sensor with a brand new VDO sensor, I don't have a voltmeter so I couldn't check if it was faulty. I changed the sensor due to the P0335 code and of course the no start ( as shown here ). But I also had the P0700 code show up as well and that scared me. Again today...

    Hey guys, Just bought a 330ci ZHP (or ZAM as the fanatics call it) up in Vancouver B.C, Canada. 2005, 88k km’s. bought from the original owner. It ran great for the first 3 weeks and now im having issues with the cold start. I’ve read tons of forums regarding symptoms and fixes. These are the...

    So real quick I have a no start no crank condition....battery is good....starter is good alternator well didn’t check yet...but it has done this before and I swapped keys and it ran fine so I continued. No it happens again. So I put a 30 amp fuse in the female EWS connecter bypassing it and it...

    On my '03 325ci tonight my car cranked for just a second then the car cut the crank and all i heard was the fuel pump. I turned the key back off and then on again and the car started right up. I feel like its probably my crank sensor going bad but my question is if the crank sensor is going bad...

    Hey all! I have been getting issues with my 01 330ci manual (Swapped from an auto) for quite some time now. I'm gonna have to keep it reasonably short. My car won't start, as the title implies, I get a crank but no start. Sometimes it will, but over time my chances of it starting have...

    Can someone please give me a step-by-step for re-aligning the EWS with the DME on MS42? I want to virginize the DME, make it work in my 328, then once start is confirmed, I'm going to custom tune from there. Well, DME is flashed with virginized BIN file, from the Wiki page, and now when i try...

    Found myself switching vehicles the other day as I needed to get to the airport. My 330Ci (automatic) wouldn't start... Car ran fine on Friday night then it sat until I needed it on Sunday afternoon. Turned the ignition key and got the typical whirrs and clicks and full dash power but only a...

    This morning I stopped for coffee, and when I returned to the car and turned the key, the starter didn't respond at all. Dash was fully illuminated, radio worked, and good voltage, it was as though the ignition was not connected to the starter circuit. I pop-started it - take that...
