    my engine idles rough after cold starts and when i'm in gear, mostly when in drive and reverse but it does happen in park and neutral but not nearly as severe originally had codes for my vanos solenoids, after replacing both with brand new oem replacements the rough idling hasn't gone away...

    In that video we gonna work on BMW E46 320D facelift 150hp M47N engine ! Mass air flow ( MAF ) sensor (part number: 13712247002) is quite easy to replace, but not the case with charge air pressure sensor (boost pressure) replacement. Let me show you how to replace it and where is located ! BOOST...

    Hello there! So I've been having some trouble with my 1999 BMW 528i lately. It started while I was in traffic about a month ago when the check engine light came on. I promptly drove it down to the local autoparts store to use their OBDII reader and it came back with the following codes - P1421-...
  5. E90/E91/E92/E93 (2006 - 2013)
    There is absolutely no difference in measured air flow in INPA when i connect and disconnect the MAF sensor, even went as far as testing the MAF being connected, but the whole sensor being taken OUT of the intake tube, which in my opinion should make the car go crazy - absolutely NO difference...
  6. E36/7 Z3 (1996-2002)
    I have a 2000 Z3. I took my car to my mechanic and he said I needed to change my MAF because of some issues I had been having and the airflow codes it was throwing out. So I changed the old one out with a brand new one and thought awesome! It ran better and I was excited. The next day I had an...

    Hello everyone, i have ran into a problem with my e36 320 ´94 After my car had started to run bad sometimes it threw a code for the maf, so i replaced that but it seems that it hasn´t done a difference and instead a new code showed up: 37 DME Main Relay : Delay Has anyone ran into this kind...
  8. X3 E83 (2004 - 2010)
    Hi. Please forgive my potential ignorance here, as I am a relatively new BMW owner. But I was just quoted $1075 to replace calipers, rotors, pads and sensors on the front of our 2006 X3. Does these seem reasonable? I am also questioning that that all of that went up suddenly as well, but I...
  9. X5 E70 (2007 - 2013)
    I have a 2011 X5 35D. I had a check engine light (3FDO) and I replaced the MAF , but I still have a cel. I have driven it about 500 miles since the replacement, but the cel is still there. It seems to run just fine and I got almost 30 mpg on my last road trip. I now think that maybe I need to...
  10. E90/E91/E92/E93 (2006 - 2013)
    Hi All - I have a 2007 328XI that is throwing a SES code (to be diagnosed) after servicing and while at a intersection, the idle RPM fell below 600 and the engine shut off. It nearly did the same the next day while the engine was cold. It seems to stabilize after its warm but when its cold it...

    Hello all, First time poster and first time BMW owner. We have a 2002 325xi for my kids' daily driver. While leaving the neighborhood, the CEL came on along with the transmission cog light. Car stopped moving. After turning off the car and letting it sit for a while (as per the manual), the...
  12. E90/E91/E92/E93 (2006 - 2013)
    So I plan on purchasing a Burger sports DCI and a ARM motorsports Charge pipe along with a Tial 11 psi BOV for my 335i 08' I already have a COBB on the OEM map. I am unfamiliar with the tuning process and read somewhere that it could be a problem if I used a mass airflow system but does that...

    Hi, i'm owner of e46 320i 2.2l car. I bought it with totally failing MAF (air consumption 0.0 on started engine, MAF error in INPA). To fix it bought used one OEM VDO from the same model car. Before buying i checked if it gives readings in INPA, started car, everything seemed ok. But after i...
  14. X5 E53 (1999 - 2006)
    2001 BMW X5 E53 3.0 160K miles Got codes for MAF replacement. Also, transmission light came on after changing bad alternator. Disconnected battery & transmission light went off. Past few days, car runns fine but transmission light came back and downshifts hard.. Replaced MAF & disconnected...
  15. 7 Series - E38 (1995 - 2001)
    My check engine light came on and showed code P102 - Mass or volume air flow sensor A circuit low. I bought a new Bosch MAF and put it on and cleared the codes. Now, the next day, the light came back on showing the same code. I wonder IF I could have purchased a bad MAF through Eeuroparts OR...
  16. 7 Series - E65 / E66 (2002 - 2008)
    Good evening, I just recently replaced the valve stem seals on a 2007 BMW 750i with a 4.8L N62B48B engine. I went to start it up and the engine runs rough then stalls. This problem never existed prior to the job. I did disconnect the and remove the intake manifold during the process, upon...
  17. E90/E91/E92/E93 (2006 - 2013)
    Recently my 2011 318D E91 LCI Touring had to go into an independent to have the timing chain etc replaced after it snapped suddenly. The car had sat for a few months on the driveway while I got together the funds. When I got it back I was informed the EGR was stuck causing hesitation/dropping...
  18. E85 / E86 Z4 (2003-2008)
    Hello all, new to this forum so take it easy on me! I've recently diagnosed my car with the horrid error code which is P1100... Again. Which I believe is caused by the MAF sensor playing up (correct me if I'm wrong). I then cleaned my MAF sensor, reset the codes and drove - after a week the...
