    Hey everyone, First post here - and thank you for the help in advance!! I have a 2015 X5 and recently I have noticed that when I use the car in the morning ( quite cold where I live) and I use the heater, I see that there is white smoke coming into the vents when i park the car, or if i am...
  2. X1 E84 (2011 - 2015)
    Hi all, I have a problem in that when I start the car with the heater on, there is a blast of condensation that hits the bottom of the inside windscreen to about 12 inches upward, this is with the venting set to windscreen, there is also a horrendous smell of carbon monoxide/fumes which...
  3. E36 (1991 - 1999)
    I recently got my ‘97 project 318 “running” and it recently started heavily smoking. Before, it would idle even though it sounded like it was just on two cylinders. Recently, I start it up it climbs aggressively to 2-3k rpm’s and dies. Every time I start it smoke billows out from absolutely...

    Oil leaking on exhaust back passenger side of engine. Pretty sure coming from valve cover. I might be tripping but I feel like I can hear a tiny hiss back there too I feel a low rumble/vibration sitting in driver seat at idle, steady idle but idk. I cannot get car in shop for a few weeks, can...

    I have an 2011 750i Xdrive I was driving from work tonight and I got a transmission malfunction message, the car shut off and I saw smoke. After pulling over I popped the hood the smoke had stopped but there was a wire burning smell coming from behind the passenger headlight, I thought I fried...

  7. E90/E91/E92/E93 (2006 - 2013)

  8. X2 F39 (2017 - current)
    Hey! I have a 2019 X2 28i with 38000 km and I have noticed that the car smokes black on cold start. The temperatures oscillate in the -15c. I didn't worry too much at first but I find that sometimes the amount of smoke is quite impressive. I don't drive the car short distances so it always has...
  9. E46 (1999 - 2006)
    First post on here Title sums up my problem. Had the valve cover gasket (along with other gaskets done) about a month or so ago that also showed smoke and a smell. The smoke came into the cabin one time. I know for a fact that it is not a valve cover gasket leak. I had the same people who...
  10. E46 (1999 - 2006)
    I had a issue with my BMW e46 320D . It was losing power and had black smoke . After problems investigation I was focused on Turbocharger Pressure transducer or so called Turbocharger regulator, it’s purpose is to control an vacuum actuator valve which control on the other hand the geometry of...
  11. X3 F25 (2011 - 2017)
    Folks, my X3 started doing something fairly unexpected recently and I do not know enough about the car to even make an educated guess. It is, first of all, a 04/2014 production 35i with 73kmi on the clock. It's been more-or-less OK in the past, save for necessitating a rather premature - I...
  12. E90/E91/E92/E93 (2006 - 2013)
    2011 318D N47 once warm (20 min of high rev driving) plumes of blue grey smoke when at 1.5k revs and over when constant pressure on the accelerator is maintained. known fault: DPF is blocked, and I’ve read it could be the failing regen causing excessive pressure and pushing oil into the...
  13. 7 Series - E65 / E66 (2002 - 2008)
    I have a 2003 BMW 745i with a Oil leak problem. I am going to a car show soon and I heard about products called “Oil Leak Stop” and I was wondering if it would work for a small amount of time because the engine randomly smokes and I won’t want that happening at the show. So is there any...
  14. E90/E91/E92/E93 (2006 - 2013)
    Hi, new to the forum, I’ve tried to include as much detail as I can think of. I was wondering if anyone has an educated guess on why I get intermittent exhaust smoke plumes when the engine is hot. scenario: 107,000 miles, no error lights or codes, and nothing out of the ordinary in a live log...
  15. E46 (1999 - 2006)
    2004 325i E46 aka “nymphoE4666” Also more exhausting and mind boggling than angsty children 😅🤦🏻‍♀️ Any way she blows thick white smoke out rear exhaust Not all the time Sometimes it’s a perfect ride Other times we white out the chic fil a parking lot while idling at the drive thru and want to...
  16. 3 Series & 4 Series
    Hey guys! I recently bought a 2003 325i with 225k miles on it. When it gets up to temp it blows smoke from exhaust. But it doesnt use any coolant. It also sounds like it has a “miss” but it doesnt throw any codes for a miss. It vibrates the car a little. Has lack of power. And it does throw...
  17. General BMW Questions
    What’s good everyone? I have a 2002 X5 3.0i 3.0L w/ 231k miles...and its smoking like a chimney. Sluggish, acceleration virtually nonexistent. Only way I can keep up with traffic is manually switching gears. My MAF sensor is bad, that’s in process as we speak. Codes pulled : P1347, P0455, P0161...
  18. X3 E83 (2004 - 2010)
    I have an X3 E83 M54. A few months back, I realized that there was smoke coming out from the vent and I thought it was just an one time event because it did not happen for a few days. The second time it happened, I tried to figure out where the smoke was coming from and it seems that its coming...
  19. E90/E91/E92/E93 (2006 - 2013)
    Hello, my e90 has some serious problems I've been trying to fix for months now. IF YOU WANT TO SKIP DIRECTLY TO MY QUESTION YOU CAN GO DIRECTLY TO THE NEXT PARAGRAPH The car throws no codes other than a VERY rare "DME MIXTURE CONTROL" code. The car stumbles, cuts off, has really choppy...
  20. E63 / E64 6 Series (2004 - 2010)
    Hi everyone! I've had a couple problems with my car. I REALLY love my car and do not want to get rid of it. First : sometimes when I'm driving the transmission malfunction light comes on and the car slows down to 40 mph. IIt will not drive any faster or change gears. Sometimes pulling off to...
