Re: 159 warning symbol
Dealer said temp gauge sensor combined with thermostat was causing temp gauge problem. Not sure about engine warning symbol but it's gone now.
Had to have wiper rack re-aligned because area in my vision was not being cleared at speed, apparently common problem on these models.
Lastly would you believe my alarm came on when I was on my way to the dealership and wouldn't turn off, I sounded like a cop car!!!, they have ordered a new unit as it showed up on their digagnostic equipment.
Will be selling next year as I don't fancy owning an Alfa without warranty.
