Hello everyone, for about two months I am proud owner of Fiat Bravo 2009, 1.6 jtdm 88kw with dualogic gearbox. I like how car drives, and I got used to semi-auto gearbox.
My problem is, that sometimes, hydrulic pump won't start when I open drivers door. I found that little "tap" on (i think that is electromotor of hydrulic pumo) geta it going, and everything works 9fine then.
And when pump doesn't work, I can't start the car. Also I noticed after driving for about 30km,and if I wont to go again in 30 min I can't start the car.
When I plugged in diagnostic I got errors
P0945 - pump relay driver
P0942 - hydrulic circuit preassure
P2904 - clutch sub-system
I think that problem is with the electromotor or some connections, because i checked on diagnostic some parameters, and I think that they were fine.
Thank you for any opinion or help.
