Chosen Solution
I purchased a 2010 BMW 328i from a dealership for 5k and about 1k in taxes, and the parts that I bought and replaced, all together it was a little over 6 grand and the person selling it said that he read the codes and it needed a transmission filter an fluid change and rear breaks. Driving it home it sounded like I had a flat tire coming from the rear, and I was under the impression that it was the breaks, and lights came on saying ABS 4x4 I ordered the parts and about 2 weeks later they came in an I installed everything, and when i start the car and start to drive the still ABS 4x4 light comes on, and it sounds like i have a flat coming from the back of the car, any ideas or suggestions on what it could be? I replaced the rear break pads, and brake sensor wire, and that didn’t help with anything. Note when I bought the car and drove it home it was making this noise, but I was thinking after I fix the rear breaks it would go away, but it didn’t. I greatly appreciate any tips, thank you very much, an I already know I am a dumbass for this purchase, but I bought this for my wife, just celebrated 25 years, 19married, she never had a nice car and she fell in love with this, but now its been in the driveway sitting for 3 months and she never got to drive it once, it still has the same mileage from when we bought it . Anyway long story short, I’m out of money and just want to fix the car for her. I currently drive a 2004 Ford Explorer with 292475 miles, so this was kinda of a big deal for her and us, we were supper exitcted to have a really nice car complety paid off, and as you can see, that blew up in my face. Again sorry so long, and thank you very much for any information or advice to get this car on the road again First pictures are normal scan second set of pics is the full system scan
@unionmandan I wonder if what you experience like a flat is actually the DSC kicking in trying to do its job. Take a look on here as well as this on to check the ABS ring and sensors. The DSC components are under the Brake section in the service manual. BMW E90 BrakesCheck those parts and see if that sheds a bit more detail into that. It’s a challenge to do this over the internet (kind of like adjusting a carb with a long screwdriver through the tailpipe) but no matter how frustrating it can get, eventually we should get there. Would be easier to wrench on this on a Saturday while drinking a beer and all but this will have to do :-) I am sure my colleague @dadibrokeit will agree with me on that.
