Hi We bought a 2008 range rover sport from someone and did not realize that the heater core was leaking coolant onto the floor cause a can bus problem. Randomly my care will have TPMS fault and the light will come on, the hazard lights start blinking, car will lock and unlock, and the radio says system shutting down. I read that this could be a cluster issue however I am leaning more to the wires on the passenger side floor because they were soaked with coolant. I have cleaned everything multiple times with electronic cleaner and even took out the transmission control module as well and cleaned it and the same thing still keeps happening. I not there is a connecter that I move will sometime cause it to happen and when someone is sitting in the passenger seat seat it will happen more frequently, but when I take the seat out and mess with the wiring the car does not ever want to do it to me. Please help me I am so frustrated and lost about this issue. Thank you.

 

Hi I had this happen when back in my P38 days -- Carpets were soaked -- turned out I went under the car and using a straitened coat hanger cleaned the AC drain ( you will get wet doing this ) -- I suggest you research this - it might help you
