Hi can anyone help I keep getting the mil light on ie the engine symbol and the fault is thermostat connection? but the garage can find no fault. Also the light will come on a few seconds after the first start up when engine is cold so thermostat not operating. Other times when driving. I,m sure it,s not the thermostat as engine gets up to temp ok and runs at 90c must add I live in spain and the temp here in summer is 40c plus but never had any overheating problems. Many thanks for any help. regads mgm
