    Sorry but electrical issues are above my pay grade. I also had some AC issues this spring but had to send it to my indy to resolve. Glad to hear you got your other issue resolved.

    Hey Fudman
    This is Kingfish that problem I had a few months ago that we assumed was a vacuum leak.... in the end... it was the intake throttle position sensor, I replace the exhaust sensor at the same time. The steelership wanted over $600 buck to fix it. I did it myself for the price of the sensors, very easy job. Got a new problem, my pusher fan has bitten the dust, can't run the AC in town only on the highway. I can do the job, requires removal of the front bumper, I've r&r the front bumper, been there dont that. Unfortuntately the male/female connector is BAD. The new pusher has the male connector but I have to replace the female connector to the harness, the steelership wants to sell me the harness for a reasonable fee, yea right. Where can I find a female connector, I've tried several sources? It requires a 12 guage 3 prong connector but I would like to use the male on the new fan rather than cutting it to adapt. You have any suggestions? I also need an MAF sensor, I read somewhere that Ford uses a Bosch type on their trucks that interchanges with a BMW just don't let BMW find out about it. The steelership wants $390. The Ford truck version, which is suppose to be the same costs about $75. Does any of this sound to good to be true?

    That is correct. I found this on a BMW I-6 blog:

    The order of the cylinders for all BMW 6-cylinder engines is 1 through 6, starting at the front of the engine. In other words, cylinder #1 is at the front of the engine (behind the radiator) and #6 is at the rear of the engine (close to the windshield).

    Hi Fudman, I hope you are enjoying your Easter. So let me see if I understand this. You are saying that Bank 1 is closer to the front of the vehicle (radiator) and that Bank 2 is closer to the rear of the vehicle (firewall). Do I understand that correctly? So cylinder 1 is closer to the front of the vehicle (radiator) and cylinder 6 is closer to the rear of the vehicle (firewall). Do I understand that correctly?

    Bank 1 and Bank 2 indicates the different exhaust streams that the sensors are located in. Bank 1 refers to cylinders 1, 2, and 3; Bank 2 is cylinders 4, 5, and 6. Bank 1 is the exhaust manifold toward the front of the car and Bank 2 is the exhaust header immediately aft of that. I think that hissing sound you hear is the secondary air pump kicking on during a cold start.

    Hi Fudman,
    I'm the guy with the 01 525i that had the vacuum leak. In the end it was 2 coils and intake position sensor, did it myself $200 parts. car runs fine unfortunately I keep getting that pesky CEL about every 60 miles. The latest and only code is
    P0174 pointing to the Oxygen Sensors Bank 2. Question I have for you,.... is Bank 2 closer to the radiator or firewall? Is Bank 2 comprised of cylinders 1,2,3 or 4,5,6? Is the only difference between the Oxygen Sensors the length of Leadin Wire? And where is the location of the Post-Cat electrical conections? I'm going to do Bank 2 tomorrow and Bank 1 next month to keep the expenses down. I'm still concerned about a vacuum leak being I get a slite hissing sound when I first start up the car, but it goes away after warming up. The car drives and excellerates fine.
