Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
DO you know if the Jag dealer was able to read any fault codes? Does the fault occur as soon as you turn the radio on?
Ok I actually think the radio is just a coincidence. Maybe the problem just occurs after driving for some time. I suspect the problem could be an issue with the electronic throttle system specifically the throttle body assembly. This will cause al those warnings and the limp mode. There should definitely be fault codes stored so I am surprised the dealer did not read any faults. Usually a P0121 or P2135 is stored. We can try using a generic OBD II tool to see if we can read the faults when the vehicle goes into limp mode.
