I have a 2011 XF Supercharged; A few months a go while evacuating from a wildfire (I live in California), it was extremely smoky and we were stuck in traffic when the car stalled out. It started up again after a few minutes and was fine immediately afterward (obviously this could be completely coincidental). A couple of weeks back, it started stalling out again. (Unfortunately, I wasn't driving it either time, but my wife says that as she was coming to a stop, the car would stall.)
I've taken it into my local Jag mechanic, and they are unable to figure out the issue. It's not showing codes and they are stumped.
Any suggestions are greatly appreciated.

 

Is it 'hunting' at idle? A couple of times mine has begun to hunt to the point that it will occasionally cut out- the problem both times was a bad connection at the MAF sensor on one of the air intakes. A bit of contact cleaner, along with making sure they are pushed all the way in, has solved the issue.

 

Thank you, I will certainly try that.

 

She probably wants a new car.....

 

Bump,
A month later and still no luck, any suggestions appreciated

Thanks,

 

Smoke test. Likely an air leak.

 

Starter fluid and spray around the intake pipes, these plastic pipe crack and cause serious issues after the MAFs.. Also check the PCV tube, check all tubing that goes to the blower. If all checks out, the throttle body might be retiring. Normally, JLR SDD would show something in the DTC timeline and advise where to look..
