If on a gradient then yes, it's the hill holder system.
It would appear that you gents are correct. It does not happen on the flat:thumbs:Your 159 will have the hill holder - It is an integral part of the VDC system.
From the hand book - Will operate on slopes with a gradient greater than 6%
OK my 10 Day old 159 2.4 has started doing this on the flat as well. The pedal stays slightly depressed and if your out of boost revs its dam hard keep the thing moving through roundabouts in 2nd gear!!Had the same problem. It was fixed by having the pivot pin on the foot pedal replaced under warranty - since then no problems. Apparently some of the pins have a layer of paint that's too thick and causes the pedal to stick on.
:lol: :lol: :thumbs:Well perhaps I should have joined and read this post previously. Had this problem with my 159 SW and it took the dealer 2.5 weeks to sort it out. New master cylinder & slave cylinder (dashboard out!), ECU remapping etc etc.... Sorted now under warranty, but how I now laugh that they were not aware of the pivot pin sticking. Still the excessive bill Alfa UK now has for the replacment parts, and the hours spent trying to fix my car seem to sooth my annoyance at the time it took to fix.
In all, a beautiful car that drives me up up the wall! But I wouldnt change it for the world.
