@Leopard - You also need to check the actual engine coolant temperature, not the fascia gauge value. The gauge will (by design) read 88C when the actual coolant temperature is anywhere between 70C and 105C, and from what you've already said there's a reasonable possibility that there is sludge in the bottom of the engine radiator reducing its ability to cool (the engine, but on this model because of the oil-water transmission cooler also the transmission).

 

Are the radiator fans turning over, even with the air conditioning (if fitted) turned off? (with Climatronic this means putting it into "Econ" mode using the control button)

@KenONeill yes the fans is running after few min of starting engine even if the AC is off or in Econ Mode , this afternoon i will receive ELM327 OBD2 interface and i have already installed torque application on my android head unites and will inform you with reading of coolant temperature as soon as i get it

@Leopard - Well, on that basis I think you may have a weak cooling system. Use the software to establish the actual engine coolant temperature, which will give us an idea of where to go next.

@Leopard - I just read a post by someone else who reported having an aircon problem, which gave me an idea. Check all the electrical connectors for the fans and thermoswitches on the radiator, and make sure they're making electrical contact.

@KenONeill i get the ELM327 wifi yesterday and plug it in but seems not working , keep giving me message can not connect to car ECU so seems not able to get real time data for temperature reading and also i have another issue to figure out why this interface not working  , any way i attached my car label for motor and transmission code , also i attached the ELM327 photo if you know some post about this
