Hi guys ive had this problem with my car shortly after i bought it last year September. Ever since we’ve been experiencing cold weather my car fails to start up properly in the morning or after being left for more than 2-3 hours. In the morning it can take up to 6-8 times before my car will stay on. It starts with the engine making a struggling noise the just dies completely . The engine light remains on. Ive changed the battery earlier this year to find it wasn’t that. Took it to a few mechanics, still no difference. Ive had a diagnostic test which came back with ‘P0115 water temperature sensor’. If anybody has an idea on how i can resolve this I’d be truly grateful.

A couple of thoughts:
1. It's always worth getting a copy of MES with these cars then you can do real diagnostics: https://www.multiecuscan.net/
2. The temperature sensor is cheap: https://www.shop4parts.co.uk/?name=store&op=Details&ProdID=2373&sku=40428
3. Have a read of this thread: https://www.fiatforum.com/grande-punto/433189-p0115-engine-coolant-temp-sensor.html Map sensors are not so cheap: https://www.shop4parts.co.uk/?name=...50&term=Fiat_Grande_Punto_1.2_8v_Sensor_-_Map

Thanks for the information, ill look to buy those items and let you know how it goes.

Hi guys I changed the MAP sensor the other day have had no problems since! Definitely worth a try if experiencing the same issue.

Thanks for the update !
