Scanners - more than a few functions

[motco]

I have a problem with my X-Type auto-levelling of the HID lights and I am narrowing it down by eliminating each component. However I understand that I shall need to recode the system once the fault is rectified - whether it is a harness break (likely) or the control module, or a suspension sensor. I am almost 100% sure it's not the stepper motor(s). Where can I get a scanner that includes headlight controls that is Jaguar compatible? The system is Hella and was fitted at least to the S Type as well. Thanks chaps!
