Bmw 550i 2006 PDC blinking sensor on i-drive

Initially the PDC system generated a PDC malfunction, the dealer said it was the left center sensor, I replaced both left and right center sensor with aftermarket. It still did not work, took to dealer and said still reads left center sensor, possibly the wiring harness in the front bumper. A 5 hour replacement process. I ordered the front sensor harness from BMW and when I got the car back from the dealer after other service work, the system was now working, but occassionally the left center sensor blinks all colors on the i-drive screen and beeps at the same time it is blinking but otherwise the system is now working find. I suspect that maybe the front harness has a short or open for that sensor. Any help before I take out the bumper to replace the harness.

Testimonial: "I can swap left and right sensors to see if the problem stays in the same place or moves. I also have the old one that was on the right side and can put in the left. I suspect it is the harness but didnt want to remove the bumper first. The swaps are easy to try. Even the dealer didn't think the aftermarket sensor use would be an issue."

2006 550i BMW What causes it to stop charging the battery

All modern vehicles have belts to drive the Alternator system which keeps the battery charged. The belt can get old and slip or even a new belt can get oil or anti-freeze on it and slip and then the battery gauge should show a low charging condition.There is also a main fuse on most cars after 1995 and on some earlier ones > Check your owners manual for fuse and main relays. The index should show you what page and then look and see if you have a main " PDC " or Power Distribution Center next to your battery. It should tell you in the manual which is the main fuse for the Alternator System. They can be anywhere from as low as 40 amp fuse to 60 amp and on certain vehicles higher. Pull the fuse if you have a PDC and look to see if it is blown. If not make sure your belt is adjusted correctly and look for any broken wires near the alternator or battery. that should help you start to find the problem...

How reset the flat tire on a 2006 bmw 550i

The tire pressure monitors I have seen require you to drive a certain distance after correcting the low pressure condition.I believe it uses the wheel speed sensors to detect a tire with low pressure(then one that is low will be essentially be giving a different reading because it is rotating more times at a given speed).I am assuming the system IS sensitive enough to get a false reading if one of the tires is a mismatched size,so keep this in mind.

I have a 2006 BMW 550i. This morning my Engine Service light came on. While I was backing out of the drive way I noticed I had a lot front end vibration in the engine area which never happens. As I started...

Sounds like its missing on one cylinder. Could be a failed plug or a blocked injector, or something more serious.

Call your dealer, who will likely suggest that you bring or more likely tow the car to them.

The dealer can scan the ECU for a fault code which will point to an accurate diagnosis.
