    I just bought an 06 325i and noticed within a few days the battery is bad and needs to be replaced. However I Have not yet had the opportunity to do so. Now yesterday I noticed a sudden very strong “rotten egg” smell only inside the cabin and trunk. Everything I’ve read suggests a bad catalytic...

    Hello guys. I have a 2011 BMW E92 328i X-Drive with an N51 engine. The car has 66 000 miles on the clock. From 4-5 months ago I have strange problems with the car: 1. The fuel consumption has increased, most noticeably on highway, with 20-30%. (Before it was around 10L/100km with 130km/h and...

    Hi, I have a 2012 BMW X3 f25 35i in great condition, only 30K miles. Recently I've noticed a smell like burnt plastic coming out from my AC left vent, only when my car is in a traffic light or stopped with the engine on for more than 10 minutes (Traffic is insane sometimes here in Miami). It is...

    I have a 2014 535d xDrive, 56000 miles. Recently I noticed a slight diesel exhaust smell coming from under the hood of my car. The car seems to run fine despite this. When I pull the sound deadening engine cover off and look at where the injectors are on top of the cylinder head, I notice...

    Hi there, So I started to notice a plastic like smell coming from the trunk of my car. I replaced my battery a few months ago, so i had my suspicions about what was causing the smell. I opened up to find that part of what i assume is called the (bst) was melted near the positive terminal...
  6. E60 / E61 (2004 - 2010)
    I have a 2004 525i, and since last year it started to smell more and more in the cabin. Its a very musky almost like moldy smell, and it gets worse when I open my rear left window. I still have not taken the door apart, although I know its easy. But I was wondering what it can be, how I can...

    Hello, I bought a pre-certified 2012 335i in April, 2015. I have been noticing a crayon/wax like smell in the car when AC is OFF, moonroof is OPEN and if I am driving. The smell gets worse in bad weather and I live in Texas. I read a few threads on this, but has anyone noticed the smell in...
  8. X5 E70 (2007 - 2013)
    Hi: I have been chasing a strange burn smell coming from the A/C vents. It only happens shortly after a hard braking or if I take a tight / sudden turn. It is definitely "different" than the smell of Oil dripping on top of the exhaust manifold (I had that issue with a e39 VCG leak a few years...
  9. 7 Series - E65 / E66 (2002 - 2008)
    Car: 2006 BMW 750i I am posting here in hope that someone might be able to give me some insight as to what is burning up in my engine bay causing my battery to completely drain. Thank you. (Note: I was not able to verify that the battery was completely drained after this event due to lack of...

    By now, we're probably all familiar with the infamous BMW HVAC system stink. There's just something about the design of the BMW heater box - the large, complex black plastic enclosure that sits between the dashboard and the firewall and contains the HVAC blower, A/C evaporator and heater core -...
  12. X3 E83 (2004 - 2010)
    I just wanted to share my valve cover gasket (VCG) experience for fellow X3 owners My symptoms: oil leak on driveway – a drip or 2 per day (adds up quick though!). Also, a slight burning oil smell, usually noticeable in park (when the car is warmed up). Oil was dripping down the transmission...

    Hello , i have a 320D , E91 2.0L . which has had it's engine overhauled, they promised med that they would change the particulate filter.

  14. E36 (1991 - 1999)
    Hey guys, I have a 95 325is and have had no issues with it after owning the car for awhile. But in the past couple weeks I have noticed a strong smell of gasoline coming from the rear of the car. I have read other threads and it seems like it could be the fuel lines or the seals on top of the...

    Hi guys, I got my 03' 330i M-sport a few weeks ago and I've began to notice that in either reverse or 1st gear (it's hard to tell which), I can smell burning coming from somewhere in the car and it's beginning to worry me. It smells a bit like oil, but my oil hasn't dropped and I can't see any...

    My 2011 328i has developed a really bad smell coming out of the A/C. I dscribe the smell as a horse or barn smell. Based on what I have read in this forum, I'm pretty sure it's the evaporator. A couple of months back, I had South Bay BMW in Torrance, CA take a look at it. They determined the car...
  19. E30 (1982 - 1993)
    Last week I filled up my 87 325i convertible for the first time in awhile. (I usually put $20 in at a time) I then drove to a friends and pulled up on his driveway (he was outside) and he commented " I can smell your car". I didn't think anything of it but then a little while later I started...

    Hi, I have been getting a musty smell when I run the heat or AC. I used some of that AC duct cleaning spray for cars and it made a little better, but did not remove the musty smell completely. My assumption is that there must be some mold or mildew in the area of the evaporator. Is there a...
