Most likely crank sensor - contact Gary at GT Autos in Burntwood, he looks after my GS (07877 053671) jetgta
I bought an OBD2 fault code reader and that shows the error I'm getting is P0128 Coolant temp below thermostat regulating temp. Done a few searches and this typically points towards a dodgy thermostat but will wait and see what Migiliore say
I had this fault code and replaced the sensor which was good for a week or 2 but the P0128 came back. I also have similar issue when starting after filling up, for me I noticed if the car battery is not full charged I get the issue, which shows P0128 - reset the code and the car starts fine. if the battery is fully charged its fine and I don't get the non start issue after filling up
so would also be interested in your results from Gary (GT Autos) - Burntwood only an hour away so would also be interested in booking the car in
I've noticed as I've used the car more it hasn't suffered with the issue so much, maybe due to battery having better charge?
Had the temp sensor replaced (part 000180137) and it now seems to be ok but I'm hoping it doesn't come back in a few weeks like what happened to EnzoMC
Gary at GT Autos is a great guy, real enthusiast and will definitely be the man I have to look after the car
this is what I had replaced - M000180137 Water Temp sensor - £17.89 would be interesting to see you still don't get the issue after the cars been left standing for few days
