Same thing for my 2004 XJR.. Twice it has stalled going through a car wash. And always at an inconvenient time.
check your climate control filter housing drain could be clogged with debris, filling to fast and spilling over engine ecu which unfortunatly is located inside car under outside air intake right foot well change filter clean out airbox it will eventully ruin ecu
I told the Service Manager at the Jaguar Dealership, and they echoed what you had said. But then added, let's hope you don't need a new ECU because it is very expensive. Also told me to not park under trees.
yes my customers that have to park under trees i remove cowl and install a prefilter under cowl so the big stuff does not get into the airbox, unfortunatly wants the circuit board gets wet the corosion process starts copper turns from green to black and then the big sleep
