just checked my car for error codes using a kkl interface cable i bought of fleebay and fiatecuscan s/w

and picked up theses errors

P0235- SUPERCHARGING PRESSURE
PO380- BOARD RELAY, THERMOSTARTER OR PREHEAT. ECU
P0236- OVERBOOST VALVE
P0110- AIR TEMPERATURE SENSOR
P0101- AIR FLOW METER

managed to clear them except PO380- BOARD RELAY, THERMOSTARTER OR PREHEAT. ECU. keep coming back after i cleared it. does this mean i need to check glow plugs?

P0235- https://www.fiatforum.com/stilo/276358-boost-control-valve.html?p=2812643
PO380- defective glow plug/s or a problem with the Glow Control Unit (cold solder on the board , was in my case)
P0236- probably caused by the same valve as p0235
P0110, P0101-- MAF sensor
