  2. F30 / F31 / F32 / F33 / F34 / F36 (2012 - current)
    Hi guys this is my very first post here as I am very new to the BMW community. I just got a 2014 BMW 428i from Florida and without a full inspection, I bought my first BMW. Now, everytime I get in the car and start the engine, it would say "reset time and date". I changed a new battery and got...
  3. X5 E53 (1999 - 2006)
    I'm new to the forum and recently purchase a used x5 which needed an engine. I swapped the current engine, an 01 x5 3.0 AWD with an 01 330ci 3.0 front wheel drive engine. The engine starts, runs and idles fine. The transmission gear selector and linkage appears to be connected properly but the...
  4. E60 / E61 (2004 - 2010)
    Started my 2004 E60 the other day and it blew the BST (battery safety terminal) out of no where and motor shut down. Purchased the C310 code reader (amazing) and cleared all faults but A375. Communication error between TCU and airbag control module. Fiber optics seem to be good. turns out I have...

    Hi guys, I am reaching out to you as a last resource since I have almost lost all my hope to get issue resolved. I have owned my E90 330i sedan for almost 7 years now and I love it. Couple of weeks ago once in a sudden out of the blue I got this warning "SOS system failure", my radio sound...

    Hello, I am new to the E90 ownership, used to have a E21, bit of an upgrade now. I just bought it used from my friends father, who took very good care of it. I did have some questions as to why the phone button does nothing on the steering wheel and the main head unit. I have searched around...

  8. E60 / E61 (2004 - 2010)
    okay guys, i decided the other day to add an aux lead to the idrive system and code it, this was easy enough :) so i started thinking what else could i add the the car at minimal expense. Almongst reading through the forum on here i decided to look and see if i could get the bluetooth working on...

    Hello, New, used, BMW owner. I am a huge DIY guy and glad to see all of the support for BMW stuff. Having an issue though that I can't seem to find a good answer online. I bought this cable for One Stop Electronics with the 7/8 pin double K line support black adapter...
  13. E60 / E61 (2004 - 2010)
    OK, so on Memorial Day I had a cooler tip over in my trunk. I lost all audio because the water went in under the spare tire and fried all the electronics under there. (Great place to put all those high priced electronics.) So after some research I decided the TCU had to be bad. I bought a used...

    Hi I recently diagnosed my sons 318i Auto to have a TCU (transmission Control Unit) problem. The initial problem was a pair of issues. battery going flat(I will explain) and the car randomly having shift problems. The trans fail light would come on and shifting gears was amazingly abrupt. so...

    I've scanned through this and other BMW forums, but I still haven't been able to locate the Bluetooth passkey for my 2005 325i. I purchased the car in 2009 and, though it came with much documentation, the passkey code was not one. I first thoroughly looked for the sticker showing the PK...

    Hello, I have a 2011 x5 35d. When I turn on the car I am getting "no warning tones" and my sound and comfort access do not work. I understand there is a problem with one of the modules in the fiber optic loop. I am getting a blinking light to the amp and no light to the TCU. I have ordered a...

  19. E90/E91/E92/E93 (2006 - 2013)
    I'm having some peculiar problems with the TCU/BMW Assist Module in my 2006 325i. I purchased the vehicle used in March of 2014 from Carmax, and the car was sold from there with a non-functional TCU. I found this out when I took the car ~November 2014 to a dealer because when I tried to...
