Many years ago I uploaded S91_AJ6 4.0 Engine Management.pdf to a few Jaguar related sites. It will explain EVERYTHING you ever wanted to know about the AJ6 4.0 engine management.
The file is over 13mb so I cannot upload it to this post.
Just search S91_AJ6 4.0 Engine Management.pdf and you will find it somewhere on the internet.
Gus will have it on his site.

An FF37 fault code is identified as a EGR Circuit fault (exhaust gas return). This can be caused by a number of things, but primarily it is the EGR Valve or EGR solenoid. The Valve is on the right hand side of the cylinders, the solenoid is on the left rear of cylinders. Likely the cause of the fault is the connectors in the solenoid are grimy, or the solenoid itself is faulty.
I cleaned the connectors, disconnected the battery, reconnected to reset the fault. All seems to be running well again.
