Evening all,
Got my car scanned today thanks to AD1.8T and broght up a 17704 code.
I have allready replaced the temp sender but the ecu light keeps returning
Im getting a slight missfires when boosting at 20PSI but not sure if thats got anything to do with it.....
What else could be the problem, could it be the thermostat??

I had this issue and code, I replaced both the G62 temp sensor and the termo, and mine was ok after that, I would highly rekconmend you use VAG parts thou DO NOT use euro car parts termos/sensors there crap and will break.
Also take a read of this (From ross tech)
17704/P1296/004758 - Error in Mapped Cooling System
Possible Symptoms
Cold start issues
Possible Causes
Coolant Temperature Sensor (G62) faulty
Coolant Thermostat faulty
Possible Solutions
Check Coolant Temperature Sensor (G62)
Check Coolant Thermostat
Special Notes
Check the stored Freeze Frame data with this fault code. Freeze Frame information will be found in the fault code description (if the module supports it) or in Generic OBD-II if the vehicle complies with those regulations.
Freeze Frame data stored at -40*C is generally an indication of a faulty ECT or wiring.
Freeze Frame data stored at +140*C is generally an indication of a faulty ECT or wiring.
Freeze Frame data stored with in the 68*C ~ 80*C range is an indication that the vehicle was close to, but not within, the cooling systems normal operation range. The Thermostat itself or Cooling system components may be at fault.
