I have a 2016 XF. I brought my car to the dealer last year with a similar issues with water in the passenger door. The dealer stated they were not able to find the cause. Last week, I tried to auto start my car and it would not start from inside my house. However, I was able to start with the key fob once I was at the door of the vehicle. I had no reoccurring auto start issues that week. One week later, I went to auto-start the vehicle and the car wouldn't start. It gave a message stating the key was not detected.
So after some research, I found there are few reasons for this message. I started with the easiest fix... a jump. The car still would not start. So, the next option was to change the key fob battery. That didn't work. I still was getting that message as well as the message battery low. So, I moved to the next fix ...change the battery. When changing the battery, I discover about 2 gallons of water in the battery well. Oddly enough, I remembered the same type of issue with the water in the passenger door. So, I removed the water from the well and totally dried the area. I then removed the battery and installed the new battery ....temporarily. And still the car did not start. But, I then realized although the car wasn't starting, I was hearing a clicking sound in the front near the engine which was indicating that battery was good and working properly.
So, now I am stuck as to what is the true issue. Is it a key fob issue? Do the key fobs just need to be reprogrammed? If so, how without having to tow my car to the dealer? Is it auto shut off issue? Is it a battery issue? Is it a electrical issue? Does, it have anything to do with the battery sitting in water for days, or weeks or even months?
The car still will not start and I cannot figure out what's the issue. And it seems that I cannot rely on Jaguar as they didn't resolve the issue last time or expose the common water issue on my last visit to the dealer.
Seems this is a common issue with Jaguar. Can anyone help?????
