Fabia 1.4 does not start

[Andreia]

My car does not start (sometimes). If I insist, for about 4 or 5 times, the engine starts to run.
The battery was changed 2 weeks ago and both sonda lambda are new. There is no problem with reles and the diagnostic device reports no errors.

Does anybody have any idea about what could be the problem?
Thanks in advance

Don't worry as it is a simple thing to replace by a garage. You need to change the temperature sensor. I have had to do this twice in 6 years.

Thank you very much for the tip. The motor light turned on last night and the diagnostic machine could detect the problem this morning. In fact, it was the temperature sensor

Glad it's sorted.
