Well just an update, my code reader arrived at 8.30am this morning and i plugged it in, told me it was either the Thermostat or the temp sensor, looked on here to see if others had same issue and found they had, changed the temp sensor and
problem sorted and the best part i have brought the reader and sensor for less then the Seat Main Dealer wanted to charge just to plug in there test equipment, took me all of 5 minutes to find the fault and 5 minutes to replace the part.
This is the dealer who we brought the car from new and there have seen the car for every service and mot in the last five years,.
Well guess what.
They will not be seeing the car again all the time i own it.
