Ok so got a check light checked and gave off these codes

P0115= Engine Coolant Temperature Sensor Circuit Malfunction

P1135=  Heater Circuit Malfunction Bank 1 Sensor 1

P1155= Heater Circuit Malfunction Bank 2 Sensor 1

The bloke at garage told me to get new P0115 Coolant Temperature Sensor and it should fix the other error codes is that true or do I need to replace all sensors

Probably true.  It often happens that a fault in one area gives false alarms in others.  It's very unlikely that both heaters went wrong at the same time.

Before changing the CTS, try cleaning the contacts - could just be a poor connection.
