Hi everyone, I recently purchased my first BMW a 1 family-owned 2002 330xi automatic with 160k on it. It served me well until I decided to replace the fan belts and camshaft position sensor. To do this I made a mistake, I broke the plastic crosshair on the MAF taking out the aribox. This might...

I am experiencing no torque under 2500 rpm, almost feels like a turbo lag. And car spews black smoke but not instantly after pressing the pedal. You can hear the turbo spool I have changed the air filter, changed MAP, and an injector The previous MAP read 1300kpa at idle and without turning the...

First post here, so please let me know if I missed anything important in this post that could help with diagnosing the issue. Ive noticed my 320d saloon will occasionally lose acceleration power, and at the same time, kicks out black smoke from the exhaust, sometimes a good amount of smoke...

Hello, I just bought my 325i and it has around 190k miles on it, should I just change the oil right away? There's a sticker in the window and it says that I have like 3k left until a change but I was wondering if I should do it anyway for peace of mind There's a little bit of sludge visible...

Hey guys, I was just driving to the store today and noticed some smoke coming from the engine bay, pulled over and traced it to under the intake manifold area. I figured just some oil leak from the valve cover gasket and didnt think too much of it. After coming out of the store, the car was...

2005 330xi w/220,000mi. Car is in perfect condition, so would like to repair if I can. Short story: drove car to airport end of December - car was fine. Went to start car on return 5 days later (single digit temperatures for days), and as soon as car was started, it was producing EXCESSIVE...

I just bought a 03 e46 (owned 2 others and an e36 so I'm not new to bmw) -- really tight car but it was stumbling a bit around 2k rpm and threw a misfire code that moved with a coil so I replaced the plugs, bad coil and MAF sensor and now it's a very happy feeling engine. Silky smooth, plenty of...

So this issue has been happening for maybe the last 6 months or so, so definitely not a sudden thing. But I thought I'd finally ask for an answer. On a cold startup, about 3-4mins after the engine has been running (so the temp needle is just lifting off the blue) the engine starts to smoke a...

Hi all Been driving my e46 318i with loving care for the last 5 years. I have been experiencing engine smoke coming from the engine bay during driving. It generally occurs when the car has been running for a minute or two, and happens for about 10 minutes and then goes away. It does come...

Hi folks, I have a 2001 318ci (E46, with N42B20 engine). Recently I was performing some routine maintenance on the car (droplinks, brakes, springs etc), and after a short drive, it felt as though it had entered the dreaded 'limp mode'. Sounding as if it was badly misfiring, I hoped it was...

2005 BMW 325i with 124k on the Odo. I was driving at about 35mph along a back road and had to pass a slow truck in my lane. I must've sped up to about 55mph very quickly and passed the truck safely. A mile down the road, I stopped at a light and turned the climate control on(it was off since it...

So just got done driving to school. Its really hot, like 95 degrees F and the humidity is up and UV index is high as well. I'm slowing down for a stop light. I had the fan on max with the A/C on and re circulation. I also had the radio on blasting some Rush. Then I smell a sweet chemical smell...

Hi my car has a smoking problem when I turn my car on it throws out a lot of blue white smoke and it's not just when it's cold when I drive it for a bit and turn it off for like 20/30mins it's trows smoke out agen and when it smokes and I try to rev it struggles to rev up but when the smoke gose...

After week holiday and not driving, last night when i turned my car on to go to the shops i could smell something wrong under the hood. Opened up and this is what I found. Is this a VCG issue or something else. Whats bothering me is that the oil is leaking underneath the screws not around the...

I just replaced my VCG today and still have a smokey smell, and can see the smoke(albeit very little) burning in the top left corner of the engine(That is looking at it from the front with the bonnet open) I can see smoke coming up. This is where it was coming from before the VCG replacement...

So my car needed a new valve cover gasket, so i put a new one in it today. Afterwards, the car drove normally until i got it up to 60 mph then stopped at a redlight. Smoke appeared to come out of the engine. Once i got home, i opened the engine and noticed white smoke poring out from the...

About 3 weeks ago I noticed a funky burnt smell come from under the hood of my 2003 325i after I turned the car off. I noticed the smell a few more times but thought it started to go away so I kind of forgot about it. Just a couple of days ago I noticed the smell again, opened the hood, and...

So I won't profess to know very much about cars, and have a potential problem I need help diagnosing. I have a 2002 320i, and I drive this little beast about 45-60 mins each way to work and back. For a couple days in a row I've had a strange problem where I see a puff of smoke about 1/2 way...

Been a while since I've been here but I thought I'd give it a try. Just recently had to garage my e46 due to smoke and misfires. These are the symptoms: 2002 bmw 325xi, 2.5L inline 6 cylinder -smoke from tailpipe -very low power and erratic idle -cylinders 1,2,4 misfire with fuel cutoff...

i have had my 330i for 2 months now and all has been ok until i popped into the town the other day for some shopping and when i got back in the car ad started it i got quite a lot of smoke out the exhaust and a really strong lingering smell of burning oil! after a few secs it cleared as if it...
