Popped my cherry - First Alfa breakdown! Fault P0191
Had my first breakdown this morning.
To begin with the car was a little harder to start, took two tries.. never done this before.
Then 15 mins into my journey 'Motor Control System Failure' and I had lack of power. 2 minutes later the car died and refused to start.
Luckily I was only 15 mins walk from work and someonce stopped and gave me a lift in the rest of the way!
I had my bluetooth OBDII reader still plugged in and the android app 'Torque' Which read;
P0191 Rail pressure monitoring
Possible causes of fault:
Low pressure circuit:
* Fuel filter blocked
* Pressure release valve defective
* Electric fuel pump
* Safety switch
The other thing I noticed was my voltage read 11.9 volts with the key in, not running (headlights and radio on). Is this too low?
