Howdy,

Anyone know what fuse #26 (driver’s side panel) covers? Car in question is a 2007 Jag XK.

 

All fuses are listed in the User Manual

 

@Cee Jay That's just one of three fuse boxes in the 4.2L X150. I believe that that one is in the front left side of the passenger compartment, with another in the engine compartment and the last one behind the leather cover in between the rear seat backs. Watch this excellent video for details:

If you have an XKR and want to enjoy hearing the exhaust all the time, you can keep the Active Exhaust valves open by removing Fuse 19 in the fuse box in the rear seat. I removed my Fuse 19 many years ago and have had no problems. I recall that the reason for the active exhaust is to provide a bit more back pressure at low engine speed to generate more low-end torque, but I'm not sure if that's true. I think it's so your neighbors don't think you're a hooligan!

Yeah, that's the one he asked about.

 

You're right, of course.

 

I was going to put all three in the post, but they all cover several pages with the diagrams and such. I didn't want to start all that copy-paste-posting.
