I already posted it on different forum but nobody has replied back. Hope you guys can help.
I would like to apologize if anybody has already posted the similar problem. I am new to DIY and, thanks to youtube, I was able to replace brake pads and oil filter housing and coolant gaskets myself. The starter has been replaced by friend.
My car BMW 525i 2007 – 140,000 miles.
One day at the parking lot, my car just wouldn’t start. So my friend checked the battery and decided to go after the starter which he was right. He removed all the filters, sway bar and other parts in order to pull the starter. That was not easy at all as many probably know. He took the starter to the shop, tested and it was bad. A few weeks later, after I got a new starter, he replaced it.
Things didn’t go as we expected
. After, he put everything back, one connector/adapter was left unplugged. He could not find where was it located at. Eventually, we realized it was a crankshaft sensor connector. Upload is a picture of connector (it has three pins with a green thing), let me know if I am wrong.
So anyway, when we tried to start the car, it went through a number of repetitive clicking noises (can’t explain the noise very well, but I uploaded a sound I recorded, you can hear what it does when I try to start the car ) before it started. I tried a few times later, same problem. Could the unplugged connector be the cause? Or maybe the air or solenoid? At this point I don’t know what that is. ..
In addition, I received the transmission malfunction error that reads: “gear can be engaged without depressing the brake….” and my “Service Engine Soon” light came on.
When I tried to drive, it won’t shift gears. It shifts to first and second but doesn’t shift into higher gears, therefore can’t really drive more than 40 miles an hour without completely killing the car.
Semiautomatic transmission doesn’t even work. It doesn’t shift at all. Also, when I tried to leave my underground parking garage, I stopped the car right on the hill to see if it has torque to drive upward without pressing the gas pedal , it started falling backward.
Also, (it’s worth mentioning) before my friend pulled starter, he took off shift gear holder while testing neutral cutoff. I didn’t get that part but long story short he took it off and put it back in. The reason I am saying it because after the starter was replaced, I began to get the transmission malfunction error that reads: “gear can be engaged without depressing the brake….” So he felt that might have caused the error.
So the outcome (after starter replacement):
1. Connector is left unplugged
2. Transmission malfunction error with the message ““gear can be engaged without depressing the brake….”
3. Car drives but doesn’t shift into higher gear
4. The delay on startup (clicking noise or missfire)
5. The service engine soon light is on
I am thinking of taking the car to autozone to read the codes. Should I drive this car at all to a close autozone?
Also, I wanna plug that connector back, but I am uncertain which parts I need to take off to make a room for plugging it back? Pelicanparts say it’s located below the starter. I saw the video on youtube how the guy replaced the crankshaft sensor taking the air intake off only…
My main concerns remain to be: the transmission failure, car wouldn’t advance into gears, and clicking noise on startup. Have you ever experienced the same problem? Besides the connector problem, what other issues I might have? Where should I go from here?
Thank you in advance guys. Your input is crucial.
