Hi all, picked up an XJ8 yesterday with a few problems. I've read loads about the gearstick sticking in park in the J-Gate but was wondering if there was a fuse or fuses to start off with witch would cause all the above problems at once. The previous owner has tried a 2nd hand comfort ECU which is currently hanging in the passenger footw (glove box is in the boot along with old comfort ECU) any help would be grateful.
I
​​​haven't really had a chance to look into it yet because I've been trying to get it out of restricted performance mode

I've read the codes so getting there

Car is a XJ8 sport 3.2 2003
