F47 and F48. It looks like there are 12 relays in the links below but not marked. This link above has them marked and none for Windows, so check the fuses

Before starting any repair work, it is advisable that you get the car scanned with an OBD scanner to get the trouble codes. Repairs should only begin after the code is interpreted. That is more cost effective and precise.

Probably a clutch fault.
Possibly maladjustment, failing hydraulic system or something the transmission must be removed to fix.

I suggest you take it to an experienced guy who will be able to tell you the fault from the feel of the pedal and a couple of cursory checks.

No way Jose.

look on the sidewall of your Tire it will say what the P.S.I. should be....

Few days ago my Son bought from a Fiat garage a second-hand Doblo (2002, diesel). The maintenance work was done at the garage before delivery the car. From the beginning an intermittent problem appeared: impossible to restart the car after having lef it unstarted from a moment (short or long does not change anything), after several retries can be started again. The mechanic guy of the garage tested the car with the electronic tooling but found nothing abnormal. Do you have any idea about what could be the cause ?
Looking at the forum I've seen mentions about the RPM sensor (defective or misaligned ?).
Thank you for your help,
