Exploring my new to me 2007 XKR convertible. I discovered that the Drivers seat lumbar and Bolsters don't adjust. The passenger ones work fine, and all other driver seat controls work fine. Not a big deal, but I like my cars sorted.

Should I be looking at fuses, or crimped wires under the seat?

 

No. My first guess is a module reprogram. Been there, done that.

 

My first thought would also be a Seat Module fault but the logical way to troubleshoot this is an SDD session which will show extended codes. The Workshop Manual lists a long series of relevant codes for lumbar and bolster harness faults.

+1 Graham.

 

OK thanks, SDD system is on the way
