  1. E46 (1999 - 2006)
    New guy here... I have a ton of experience with VW & Audi, just not BMW so much (love my German cars). I'm ripping apart a 00 323 that I'm turning into a death cart. Please don't bag on me, it had a lot of body damage and it didn't make financial sense to fix. It runs and drives good and was...
  2. E60 / E61 (2004 - 2010)
    I've got a 2005 525i with the older 2.5L M54 engine. I've been having the P0011 or 28B6 error intermittently for the past couple of years. I have noticed that when the error is gone (service engine soon light is off on the gauge cluster) it typically comes back on startup when its a bit colder...
  3. F10 / F11 (2011 - 2016)
    Hi, wonder if someone could help me. I’m not a car expert at all. I had an amber engine warning light for a little while on my 520d (F10) so rather than pay a garage for a diagnostic I bought an OBD2 reader. I got these 5 error codes: P00BC P00BD P22AE (twice) P0471 I thought it was the...
  4. 7 Series - E38 (1995 - 2001)
    So my 2001 740iL acquired a cylinder 5 misfire and fuel cut off over night. When I ran the code scanner, one other code popped up. Not only was I getting the misfire code, I also got a “Camshaft Position Sensor A Circuit High Bank 1 or Single Sensor” (Code P0343). I didn’t know if this code...
  5. E39 (1997 - 2003)
    Hey guys, my 1997 523i had a crash back in 2018, only radiator was damaged, nothing much, and was fixed by previous owner, however, i'm pretty new to BMW's i bought it a few months ago, and i was doing the usual check of the engine when i found out that the coolant temp sensor that is located on...

    Hi there can anyone help?, i have a e46 2003 2.L with cam sensor errors. I've recently changed one with no trouble at all but the after market intake sensor seems to be too big for the hole.. I've seen online people just changing them with ease but mine just dont seem to fit. unless i need to...
  7. E39 (1997 - 2003)
    hi everyone. recently i had a short in my o2 sensor connector for b1s1 which was fixed by my mechanic. however ever since i have been getting this p1083 code and the b1s1 voltage flatlining at ~0.33V when driving i just then checked with key on engine off and the voltage is at 1.275V whereas...
  8. F10 / F11 (2011 - 2016)
    Hey everyone, So I keep getting a notice that my coolant level is low; however, my reservoir is maxed. I recently drained what I could and replaced the sensor in the bottom of the overflow tank and I am still getting the same notification. Engine isn't overheating otherwise and everything else...
  9. X5 E53 (1999 - 2006)
    Hello, so I have e53 2002 diesel and I noticed that the engine is quite loud, also when I am driving for a long time especially when going uphill for example in the countryside, after 1.5 hours of driving the oil pressure warning light comes on and it is flickering when pushing the gas pedal...
  10. X5 E70 (2007 - 2013)
    So today, car threw codes - P0072 - Ambient Temp U0155 - Network P0674 - Powertrain After much googly searching, and this forum, I'm at a loss as to where to find the Ambient Temperature Sensor unit. I've seen many pics and videos of them exposed under the passenger side area, but our 2013...
  11. E36/7 Z3 (1996-2002)
    Hi all, I'm new to the forums, but have seen some great trouble-shooting tips here, so hoping I can get some tips here related to my Z3. I have a 2001 2.5i with a brake issue. I've had it for a while but finally got around to trying to actually fix it. Initially I could drive down the road...
  12. E39 (1997 - 2003)

  13. E36 (1991 - 1999)
    Hi folks. My Brake Fluid light is mostly on these days. I have bought some DOT-4 fluid and topped it up. The reservoir is still full. It hadn't dipped. But the light still is on. No sponginess (in fact it reduced when I topped it up), and brakes are fine. What could be the problem...

  15. E63 / E64 6 Series (2004 - 2010)
    I am getting fail codes on Catalytic converter.. also on BanK 2 up and down on the O2. Do you think it is the Cat or the O2 sensors? or something else. ?
  16. E36/7 Z3 (1996-2002)
    After a few days and some work I have figured out that my 97 1.9 Roadster isn't starting because of my fuel tank pressure sensor not being plugged in. Does anyone have any info or links that can point me in the right direction to finding where that sensor is located and where that pesky...
  17. X3 E83 (2004 - 2010)
    Replaced it today. What a pain in the butt! Easy procedure in theory: 1. Remove plastic engine cover (I keep mine off so that was already done) 2. Remove two e8 bolts holding bracket above o2 sensor and pull out bracket 3. Remove O2 sensor. 4. Put everything back Tools: 22mm 3/8 inch crows...
  18. E46 (1999 - 2006)
    So my dash is reading the classic -40 due to what I thought was a faulty sensor. I buy a new sensor and go to replace the old one. I drive a RHD 2001 325Ci, when I get to where the sensor should be located I find this: First of all what I thought would have been an old faulty sensor was not...
  19. E82 / E87 / E88 / F20 1 Series (2008 - 2014)
    HI all, I recently replaced my Upstream O2 sensor as it had failed (shorted). I ordered one checking the correct part (11787569930) and it arrived with a short (!) cable but the connector was correct so I extended it using my old cable harness (soldered + heatshink). Now I am constantly getting...
