Had this from another garage. EML on. Fault codes P1116 heater open circuit intermittent. P1103 heater capacity too low and also P1297 Valve connection pressure loss intermittent (turbo) Checked live data using Solus, and at tick over closed loop but 'blip' the throttle, goes open loop. Again closed at idle. Also heater switching all the time. I think it has a Titania sensor. I know these switch the heater on and off but the above does not seem normal. I have not done any other checks so far and this is the first time I have come across a problem with this type of sensor. vehicle done over 70000 miles so could be due a sensor but would like to understand my readings more. Hope you can enlighten me.
