Hello all,

So in the aftermath of the coolant failure/the nipple of the expansion tank breaking off and spraying coolant throughout the engine bay, I’ve now got a new issue immediately thereafter in my XJR.

BONNET OPEN warning ⚠️ started after a few days along with the dreaded random activation of the car alarm. Thankfully not happening at home since the car is unlocked in the garage. But very embarrassing when it goes off when I’m out and about town. I’ve tried opening/closing the bonnet. No change. Both mechanisms look fairly dirty. Would not be surprised if coolant got into the mechanism/s and fouled them. Thinking a bit of GOO GONE sprayed inside and some cleaning with a shammy as best as I can?

Tried rinsing then with hose but water alone did nothing.

Otherwise it’s back to mechanic…?
