I have a 2007 4.8.

Changed the battery last year because my car died.

They told my they ran all the electrical faults and started troubleshooting them all. Somehow, they came to the pdc harness and unplugged it. Drove it for about 15-20 miles and now faults at all.

So here's the new story. Here's were it gets interesting. After giving the X a final car wash and taking it on a final test drive, the transmission malfunction light turned on! They didn't know what happened. They think water obviously has something to do with it.

They basically took the car apart. Front and rear seats, carpet, etc.

I know the tech is good. He always serviced my cars when he worked at bmw for 20 years. He also mentioned that the 07 X5 has electrical problems.

Any help so I could pass this along would be appreciated.

Starting to think I should trade in the X. Sad part is it only has 66k miles.
