    My recently bought 2013 X3 2.0i is showing signs of engine wear and I’ve been advised it’s only going to get worse. I’m wondering if its possible to swap this engine for a 2.8i or even a N52 6 cylinder for more power?
  2. E60 / E61 (2004 - 2010)
    Hello all I saw a few threads about ECUs but none in particular with the E60 and I was wondering will a Reset help it relearn with its High flow panel filter and Muffler delete only. The Car has seemed confused after the delete (mainly the MPG needle gets confused such as going to the lowest MPG...

    Video of noise here: It was low on coolant so I filled up the reservoir a bit under the max. I drove it around after fixing an electrical problem and everything seemed fine. It wasn't making this noise when it started up, but it has been sitting for a few months. After about 10 minutes of...
  5. E60 / E61 (2004 - 2010)
    Hello first time here in the BMW forums and as a owner of a BMW, as a past 97 Thunderbird owner this euro thing is all new to me haha. I’m not looking for Crazy gains but atleast some more pep in the step. I believe the N52B30 on this makes 215HP however I’m testing the waters to see if I can...

    Hey (Sorry for bad English) I would really appreciate some tips or something that might lead me in the right direction. Bought a 335d e91 for about 3 months ago.

    Hoping for some insight here please! Had a catastrophic N63 failure 2 months back due to losing an oil cooler line while on the highway. Long story short, car towed to mechanic, new N63 long block swapped, and now mechanic doesn't know why there are about 80 something error codes when car...

    My 2013 BMW X3 (103,000 miles ) , went into Parking mode while at 70 mph speed and was not accelerating or going into drive mode and I had to pull it to an emergency lane. I turned off the engine button and then when I tried to turn it back on, nothing was happening. Everything was normal on...
  10. E90/E91/E92/E93 (2006 - 2013)
    Hey! I was wondering if anyone else has had this issue, and if yes, what it turned out to be. I’ve taken my car to a certified BMW technician three times and my car refuses to do it while it’s with him, so I’m getting sort of desperate because this is kind of freaking me out. Sometimes, when...
  11. E39 (1997 - 2003)
    Hey y’all, this is a follow up post to my last one. I have a 2003 525i auto. I’m having a big leak on the underside of the car near where the transmission meets the engine. The leak looks to be a mix of burnt oil, coolant, and possibly some sediment (not 100% sure). I will attach some pics here...
  12. 7 Series - G11 / G12 (2016 - current)
    I thought this would be useful for all new owners, but also for myself as I am just getting a remanufacture engine installed by BMW in my 2016 750Li xdrive. Here are a couple of links I found and I thought I would ask everyone to see if they had specific tips to promote Engine Longevity and...

    Hello, I have a little worry with my vehicle. Thanks in advance, to whoever reads this text and sorry in advance for the length and my bad English. :-) In the German forums you will find absolutely no help. There are statements like: "Throw the car away" and no help at all. ### Vehicle BMW...
  14. F20 / F21 1 Series (2012 - Current)
    Hey guys, This morning I started up my F20 and heard an unsual noise from the cabine. I opened the car's bonnet and there was a loud "whistling" noise coming from the engine bay. After driving the car around a bit and getting it to warm up, the sound seems to fade. Here's a video where you can...
  15. General BMW Questions
    Recently bought a 2nd hand 320i and it passed its MOT with no advisories so assumed everything was fine. Had it a few days and when I get up to 4500+ RPMs in 3rd/4th/5th gear the engine cuts out. The yellow engine light has come on and starts blinking when the engine cuts out but then returns to...

    Hey X5 family. Im having an issue with a rattling sound coming from the engine of my X5. It sounds like its coming from the top of the engine and it just started maybe a week or so ago.

  18. E30 (1982 - 1993)
    I'm breaking down my e30 to attempt an electric conversion and need to get rid of some parts. The main thing is the engine. It's a little underpowered and puts out a top speed of about 60mph, some of which is due to a broken radiator. I was wondering if anyone would like to purchase the...
