2009 XF Supergharged Compression Issues
#1
![Exclamation](https://www.jaguarforums.com/forum/images/icons/icon4.gif)
Need help. Well maintained XF Supercharged has a compression problem and local Jag mechanics are stumped.
"Restricted Performance" alert came on.. Hot day 95 degrees... driving in stop and go traffic. Limited compression.... step on gas, no response.... no downshifting, just maintain current speed. Limped into dealership. Had it for three days,,, said it was the mass air flow sensor. Replaced... $500... All well next day until hot afternoon, 94 degrees... same issue "Restricted Performance" light came on. .Limped back.
Had it for five days... "cannot duplicate"... kept "to drive in hot weather"... still no resolution.
Diagnostics verifies "Restricted Performance" illuminating.
Still in shop and they are stumped.
Anyone?
Thanks, Joe Glasson
