EGR valve gaskets, sooting.
Had a mare of a week in France, the blessed 159 gave up on the first day!
No power and a whining, blowing sound when asking for power, esp up hills.
Towed to the local Alfa garage, EGR and absolute pressure sensor diagnosed.
600 euros later......and it feels ok.
Not perfect, feels like is back to 150bhp stock rather than the previous 180+bhp.
Checked the valve when we got back to the gite, 200 miles return drive.
The EGR has soot showing on the exhaust gasket, manifold gasket looks clean.
I wiped the soot away and will check later, the gasket and seal doesn't look that good to me.
Would a blowing gasket reduce power?
I can also hear a blowing noise at higher revs.
Will have to re-torque the bolts when I get home, or re-do the gasket.
Moved over to the dark side
And loving it
