Oil pressure gauge goes beyond the max reading under normal driving conditions. It does not return to zero when engine shuts off but, only returns to 129psi reading. Oil level & oil pressure are good

Cluster replaced and still having issues.
Took to dealer to have it repaired twice.
Insttrument cluster causing coolant temperature to stay stuck at 260. Doesn't have code for overheating showing nor does it have any other signs of overheating, checked with pyrometer. Lower hose is cooler than upper house but both are within range
