Fault code B1200-66, check for frontal damage. Exept I haven't touched anything at all. But I have travelled some atrocious witer roads which are icy and very bumpy. I haven't bottomed the suspension though. When my local specialist tried a readout with autologic the sytem threw up "Too many transient events".
Any pointers to what part of the system is causing this? There are several sensors and of course the "airbags" at the rear corners of the underbonnet area.

 

I'll guess it's an XF but Model Year would also be a useful addition as your forum Signature.

The PPS (Pedestrian Protection System) is notorious for false warnings on other Jaguar models and was even known to deploy on early XK's without any impact.

If you definitely haven't touched anything, the most likely cause is a failed impact sensing sensor. There are two - left and right behind the front bumper. Relevant Part Number depends on VIN range.

The diagnostics said: Too many transients / events. So I think I have a case corresponding to this (XK) TSB as my XF is a MY2008:
