Alfa 156 2.5 v6 Q System Cold start with poor brake servo involvement
I've came across this bulletin in the following website
Alfa Romeo Technical Help
and i'm facing the same problem on the brakes during cold starts.
Alfa Romeo 156
The brake pedal stays initially hard after cold start with poor brake servo involvement.
All vehicles having Q-System Automatic Transmission.
After cold start, the vacuum at low speed is not enough.
Check the vacuum intake system type and if required, then change the vacuum intake pipe with one having part no 60664715 and change the corrugated intake hose with one having part number 606673919. Also use two collars of part numbers 13126170 and 13126770.
I've managed to find the all the parts from eper but the corrugated intake hose with the part no 606673919 doesn't seem to be listed in eper.
Anyone here has managed to fix the problem with the right part no.
